Executive summary
Recent developments have shown that the global energy transition has gained sufficient
momentum and that it is now more a question of when, rather than if it will be achieved.
Renewable energy cooperatives (RECs) are one of the important accelerating elements in the
European energy transition. Allowing citizens and companies to invest in renewable energy
power plants and thereby to become independent power producers, has helped accelerating the
acceptance of renewable energies among the population and moving towards a more
decentralized and sustainable power supply.
The Erasmus Center for Future Energy Business, a think tank of the Erasmus University
Rotterdam, intends to apply the benefits of RECs to the Port of Rotterdam, one of the world’s
biggest industrial hubs and, according to several authors, a major energy cluster. To support the
Center in its endeavor, this thesis researches how a REC would have to be designed to increase
solar energy deployment at the Port. A progressive case study, containing 18 interviews within
the German and the Dutch REC sector and the business community of the Port of Rotterdam,
leads to identify specific characteristics this REC would have to contain. The results of this
thesis show that there are 14 characteristics a REC should contain to increase solar energy
deployment at the Port. Since most of these characteristics are independent of the scope of the
cooperative’s activities, the results of this thesis can - in fact - be an inspirational source for the
Center, irrespective of how it eventually decides to launch the cooperative. Additionally, this
thesis provides insights on the general readiness of the Port to engage in energy cooperation
and it discusses the effects an energy cluster might have on a REC at the harbor.
It is shown that establishing a REC at the Port of Rotterdam is a promising idea, but that the
success of this project will depend on its implementation. Therefore, concrete recommendations
on how to design and launch a cooperative at the Port are given and future research topics that
will increase the understanding of the research topic are provided.

1. Introduction- Energiewende at the Port of Rotterdam?
"Do you know how the [German] word Energiewende translates in Spanish? Or in Arabic? Or
in Indonesian? The answer will surprise you, because it simply translates into Energiewende."
These were the first words of Franz-Walter Steinmeier’s - Germany’s foreign minister -
inauguration speech of the 2015 summit on Energy Transition in Berlin. The German word
Energiewende can be translated as energy transition and refers to the transition from energy
provided by finite fossil fuels to renewable energies (Hennicke et al., 2007). In fact, Germany
belongs to the leading suppliers of renewables in the world, as alternative energy resources have
covered a third of the country's energy consumption in 2015 (Meyers, 2016). Therefore, it is
not surprising that the German foreign minister takes some pride in presenting this anecdote to
the public.
Having observed the energy transition closely throughout the last years, it is interesting to
witness a change in narrative regarding renewable energies. Only five years ago, major German
energy companies still lobbied against the support of renewable energies (Schultz, 2011) and
the 2009 UN climate summit in Copenhagen was considered a failure (BBC, 2009).
In 2015, however, it seems like a turning point was reached. After having suffered severe losses,
major German energy companies such as E.ON and RWE decided to pivot their strategy
towards the use of renewable energies (E.ON, 2015). At the same time, the public discussion
has moved from debating whether renewables should be part of the German energy mix at all,
towards how fast 100% renewables could and should be reached (Presse- und Informationsamt
der Bundesregierung, 2015). Furthermore, at the 2015 UN Paris climate summit, a noticeable
deal was signed, which stated in surprisingly clear wording that renewable energies shall be the
energy source of the future (Harvey, 2015).
This development shows two things. First, results of the energy transition so far have convinced
many stakeholders within the energy industry that renewable energies are not simply a utopist
idea, but that they can be a highly profitable and smart mean of procuring electricity. Second,
even though the word Energiewende might have the potential to become a linguistic
Germanism, it would be wrong to categorize the energy transition as a mere German
phenomenon. In fact, recent developments such as the 2015 Paris summit or China's massive
Moritz Hentschel, 441663 – Master Thesis

Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
investments in renewable energy sources (St. Fleur, 2015) leave little doubt that the energy
transition is just getting started on an international level as well.
This can be seen as one of the most promising global developments in recent history. The reason
for this optimism is that renewable energies, especially solar energy, offer two major benefits.
First, they are relatively clean; second, they can be used in a decentralized manner (Robyns,
2012). While the first benefit is widely known, the latter rarely receives the attention it deserves.
In fact, decentralization has played a crucial role in the Energiewende, as private households
and companies invested in solar systems for self-consumption to decrease their energy bills
(Braun, 2009). This led to a more varied energy industry and eventually evolved into what is
called the "democratization" of energy supply (Kaphengs and Velten, 2014, p. 41).
Since the energy transition led to an increasing democratization of the energy market, new
players, different from the conventional energy corporations, entered the industry. One of the
most visible developments was the emergence of Renewable Energy Cooperatives (RECs). As
Graph 1 shows, Germany witnessed a significant increase of new registrations of energy
cooperatives in the last decade. Whereas in 2006 86 new cooperatives registered per year, in
2013 this number had increased more than tenfold.

Based on the well-known concept of cooperatives, which emerged in Europe in the 19th century
(Bonus, 1994), RECs (not to be confused with Rural Electric Cooperatives) give individual
citizens and companies the opportunity to on the one hand bundle resources and become a
renewable power producer and on the other hand participate in cooperative energy
consumption. Through the increasing international acceptance of renewable energies, RECs
gained ground in many countries. For instance, the European federation for groups and
cooperatives of citizens for renewable energy and energy efficiency currently counts 1,240
RECs within its federation and a total of 650,000 European citizens as members.
Given this remarkable rise of RECs, it is expedient to look for new opportunities for energy
cooperatives in the global energy transition. Therefore, this thesis will analyze how such a
cooperative could help the Port of Rotterdam, one of Europe's major conglomerates of
companies and a macroeconomic power house, in achieving its own energy transition.
The idea for this research topic emerged at the Erasmus Energy Forum 2016, an industry event
organized by the Center for Future Energy Business of the Erasmus University Rotterdam.
During this conference, Professor Dr. Wolfgang Ketter, founder and director of the Center,
introduced the idea of an energy co-operative at the Port of Rotterdam aiming to facilitate an
energy transition at the harbor. As shown above, energy co-operatives, and in particular
Renewable Energy Cooperatives (RECs), constitute a growing phenomenon in the European
energy landscape and have been a highly successful answer to the challenges of the energy
transition (Agentur für erneuerbare Energien, and Raiffeisenverband, D. D. G. U., 2011).
Inspired by the idea of launching an energy cooperative at the Port, the researcher decided to
dedicate his master thesis to this project. Due to the researcher’s working experience as a solar
energy project developer and since photovoltaics is the most commonly used technology by
energy cooperatives (Yildiz, 2013), it was decided to investigate how this REC would have to
be designed to increase the solar energy deployment within the harbor.
In fact, the Port of Rotterdam has ambitious targets regarding the usage of solar energy. In its
Vision 2030, a working paper through which the port authorities lay out a roadmap for the
evolution of the Port in the next decades, the authorities state the goal that by 2030 “almost
every roof [of the buildings located within the port area] has solar panels” (Port of Rotterdam
Authorities, 2011, p. 25). Apart from the well-known environmental benefits such an
Moritz Hentschel, 441663 – Master Thesis

Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
undertaking could bring, there are several practical reasons that help explain this ambitious
target:
The companies located at the Port of Rotterdam have an immense combined electricity demand,
which according to the port authorities sums up to approximately 10-20% of the entire Dutch
electricity consumption. At the same time, due to their economic activities, most companies
own large warehouses with plenty of roof space available for solar energy power plants. The
port authorities estimate that there are 3,500 hectares of available roof space (Port of Rotterdam
Authorities, 2011), which with current photovoltaic technology could harbor an impressive
solar power plant with a peak capacity of 4.5 GW. This would be roughly 3 times the amount
of solar energy power plants installed in the entire Netherlands at the end of 2015 (International
Energy Agency, 2016). Furthermore, most of the roofs at the Port, especially those of the
warehouses, are made of trapezoidal sheets, which provide one of the most economic surfaces
to install photovoltaic systems on (Riedel, 2010). Finally, there are many cold storages located
at the Port, which could be used as batteries to balance the variable output of solar energy.
Hence, theoretically, the Port of Rotterdam harbors highly promising conditions for the
deployment of photovoltaic roof top power plants. Surprisingly, on its website, the port
authorities state that the "use of solar energy in the port is still in its infancy". It appears that,
until now, individual companies at the Port did not have enough incentives to make use of solar
energy on their own.
This thesis posits that by pooling resources with other companies, synergies can be reached,
which make it much more attractive for the Port community as a whole rather than for individual
companies on their own, to deploy solar energy. Since a REC can be an effective mean to pool
resources, launching a renewable energy cooperative at the Port could be a possible answer to
the mismatch between the harbor’s potential and actual deployment of solar energy.
In the following, the research question will be presented that will guide this thesis towards
finding out how an REC should be designed to support the Port in its energy transition.
1.1 Research question
Having posed that a REC at the Port of Rotterdam might have the potential to increase the
likelihood of solar energy deployment by the companies located within the harbor, it is
Moritz Hentschel, 441663 – Master Thesis
5
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
important to understand how such a cooperative would have to be designed to facilitate this
outcome. Consequently, the goal of this research will be to investigate the following research
question:
Which existing or potential characteristics of renewable energy cooperatives would an
energy cooperative have to contain to increase the likelihood of solar energy deployment at
the Port of Rotterdam?
This research question is divided in two parts. The first part aims at identifying common
characteristics of RECs. The second part aims at researching, which of the existing
characteristics as well as which characteristics lacking within the current structures of RECs
would lead to an increase of solar energy deployment at the Port.
Having gathered this information, the researcher should be able to provide recommendations
on how a REC should be designed with the intent to support the Erasmus Centre for Future
Energy Business in its endeavor to successfully establish an energy cooperative at the Port.
Furthermore, by carving out the most important characteristics a REC would have to contain to
facilitate the deployment of solar energy at the Port, this thesis shall support the latter in its
quest to become “…the most sustainable port of the world.” (Port of Rotterdam Authorities,
2014, p. 6).
The structure of the thesis will be as follows: first, a literature review on relevant topics
concerning the research question will be performed. Second, a research framework, capturing
the reasoning of this thesis will be presented. Third, the methodology of this research will be
outlined, including a description of the research process. Fourth, the research findings will be
depicted. Fifth, conclusions will be drawn from the results to answer the research question.
Finally, the conclusions will be discussed, limitations and future research topics will be
presented and theoretical and practical implications will be outlined.
2 Literature Review
This thesis follows the progressive case study research strategy (see Research strategy).
Accordingly, the literature review will have three general goals: first, creating awareness of
what is already known about the topic researched, second sensitizing the researcher for all
Moritz Hentschel, 441663 – Master Thesis
6
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
crucial concepts related to the research question and third, enabling the researcher to direct the
data collection in promising directions (Steenhuis and De Bruijn, 2006).
Consequently, this chapter will be structured as follows. First, the concept of RECs in general
will be introduced. Second, literature on how RECs can lead to increased solar energy
deployment will be presented. Third, RECs composed of companies will be explained in more
detail by analyzing theory on strategic alliances. Finally, the concept of energy clusters will be
introduced to provide a better understanding of the environment in which the REC would be
placed. Emphasis will be put both on academic articles as well as publications of public and
private entities that are active in the energy industry.
2.1 (Renewable Energy) Cooperatives
In the literature review on RECs, three concepts will be discussed, gradually increasing
specificity: first, the general concept of cooperatives will be introduced. Second, the more
specific concept of (renewable) energy cooperatives will be presented. Third, literature on
photovoltaic energy cooperatives, a particular type of RECs, will be reviewed, preparing the
reader for the subsequent research on solar energy deployment at the Port of Rotterdam.
2.1.1 Origins and definition of cooperatives
Cooperatives are organizations enabling economic collaboration among individual actors.
According to the International Cooperative Alliance, corporative businesses employ 250
Million people worldwide. Especially in the agricultural sector, cooperatives constitute a
"prominent [...] organizational form" and in many European countries, agricultural cooperatives
control approximately 50% of the market share (Ménard, 2000, p. 335).
Some authors define the founding of the Rochdale Equitable Pioneers Society in England in
1844 as the birth of modern cooperatives (Pezzini, 2008). Subsequently, the International
Cooperative Alliance has evolved as the predominant authority on the matter. According to this
non-governmental organization, a cooperative should be defined as follows:
"A co-operative is an autonomous association of persons united voluntarily to meet their
common economic, social, and cultural needs and aspirations through a jointly owned and
democratically-controlled enterprise."
Moritz Hentschel, 441663 – Master Thesis
7
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
There are several aspects within this definition that should be highlighted for the purpose of
this thesis. First, this definition applies the word persons, meaning physical as well as juridical
persons. Accordingly, cooperatives can be composed of both, individuals as well as companies.
Second, cooperatives assemble persons with common needs and aspirations. This hints at
aspirations that would be too difficult to achieve by individual members of the cooperative.
Further, such aspirations can be limited in scope, meaning that a cooperative can tackle one
specific goal or set of goals. Consequently, cooperatives enable companies who normally are
in a competitive environment with each other, to collaborate on specific tasks of common
interest (BWGV, 2016). Finally, emphasis should be placed on the fact that cooperatives are
businesses that seek not only profit, but also have shared goals for a better world through
collaboration.
2.1.2 Cooperatives and transactional cost economics
Since the concept of cooperatives refers to a specific type of organization that governs how
agents interact with each other, research on cooperatives is often linked to the academic field
of transaction cost economics. Among other things, this research area focuses on the question
of which form of relationship a person should chose when working with others (Ring and Van
de Ven, 1992). The initial answer, transaction cost economists provided to this question, was
that one could either choose to use the market and contract other people or one could choose to
set up a proprietary hierarchical structure to vertically integrate all parties of the value chain
(Williamson, 1987). However, according to some authors, this view is too limited (Ring and
Van de Ven, 1992; Ghoshal, S., and Moran, P., 1996), since there are alternative types of
collaboration, such as alliances and cooperatives. It can thus be concluded that cooperatives
must be differentiated from hierarchical or contractual organizations.
2.1.3 (Renewable) energy cooperatives
Even though it has been stated that agricultural cooperatives are the predominant type of
cooperatives, energy cooperatives have significantly gained in importance in the last years
(Graph 1). To explain this phenomenon, this subchapter will provide a literature review on
energy cooperatives in general and RECs in particular.

Predominance of RECs
When researching energy cooperatives, it is striking that most publications on the matter refer
to renewable energy cooperatives. To understand why energy cooperatives are gaining in
importance and why this refers mainly to RECs, it is expedient to look at the history of German
energy cooperatives, whose origins trace back to the end of the 19th century (Yildiz, 2013). In
that time, due to insufficient grid infrastructure, local actors formed energy cooperatives to
organize electricity production and distribution network. This shows that originally, energy
cooperatives were not yet linked to renewable energies, but emerged out of the desire to provide
basic energy infrastructure. Then, after the Second World War, due to extended economic
growth, electricity demand increased dramatically. Since individual energy cooperatives did
not have the resources to meet this demand, they lost in importance and gave way to bigger,
national energy companies. As an exception to this trend, one should highlight the ongoing
importance of energy cooperatives in highly remote areas, where due to insufficient demand,
energy cooperatives, composed of local actors, continued to play an important role (Yadoo and
Cruickshank, 2010). Still, because of the above mentioned increasing energy demand within
the more densely populated areas, the dominant energy infrastructure in Germany (and
globally), has been organized in a central manner, often maintained by state owned companies
(Bauwens et al., 2015). However, due to the gradual re-decentralization that was caused by the
global energy transition, this situation started changing again. Since decentralized energy
systems offer several important technical advantages over centralized systems, a decentralized
energy industry emerged. This lead to a more active participation of the individual energy
consumer and to the development of the now highly popular term "prosumer" (Van Der Schoor,
T., and Scholtens, B., 2015, p. 2), which is a neologism composed of the words consumer and
producer (of energy).
The rising popularity of energy cooperatives and their strong entanglement with renewable
energies can thus be explained by the two benefits of the energy transition, mentioned in
Chapter 1. First, decentralization led to a more active involvement of energy consumers who
formed cooperatives. Second, the increasing profitability and the major ecological advantages
of renewable energies motivated cooperatives to choose renewables as their main energy
sources, thereby evolving into RECs. Today, the European Union's leading association of
RECs, the European Federation of Renewable Energies Cooperatives (REscoop) estimates that
Moritz Hentschel, 441663 – Master Thesis
9
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
there exist approximately 2,397 RECs in Europe of which most are in Germany, Denmark and
Austria, Sweden and UK.
Having established that RECs are currently the most common type of energy cooperatives, the
different classifications of RECs as well as their composition and main activities will now be
presented. This is intended to help grasping the nature of the concept of REC’s.
Classification of RECs
The most commonly used classification of RECs refers to their purpose (Yildiz, 2013):
Energy consumption cooperatives help organizing bundled and well-coordinated energy
purchases for its members. Through such cooperatives, peak demand can be optimized
and better prices on the spot market due to larger purchase quantities can be achieved.
Energy production cooperatives, the most common form of RECs, enable a group of
persons to produce and sell energy together.
Energy service provider cooperatives act as service providers for a group of already
existing energy providers and cooperatives. Their purpose is to bundle resources for
activities such as energy purchase and sales. Energy related service providers often also
offer consultancy services.
In addition, RECs can be differentiated by the technology they use to produce and choose as a
resource to consume energy. Here, photovoltaics is most commonly used, next to wind,
biomass, geothermal, water and wood (Yildiz, 2013).
Finally, other types of cooperatives include energy communities or technical parts purchase
cooperatives. This shows that the REC movement is highly heterogeneous, which is not
surprising, since the diversity of economic agents in the energy industry is one of the results
triggered by the decentralization aspect of the energy transition (Gailing and Röhring, 2015).
Typology of RECs
RECs are mostly composed of citizens, business involvement into cooperatives being the
exception. Vansintjan (2015) shows that in Germany only 3% of RECs' members are
companies. Additionally, he found out that the average German REC operates power plants
with a total peak capacity of approximately 1 MW, distributed among 7 plants (approximately
Moritz Hentschel, 441663 – Master Thesis
10
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
150 kWp each). REscoop further explains that RECs normally invest in local energy sources,
meaning facilities that are geographically closely located to the residence of its members. In
fact, the possibility to invest in local energy procurement is one of the main reasons why
cooperatives invest in decentralized energy technology such as photovoltaic energy. In addition,
the Federation mentions that it is not rare that RECs start by limiting themselves to one
technology, mostly solar or wind energy. However, once a REC is formed and it has
successfully implemented a project, the cooperative often becomes active in adjacent fields,
such as energy efficiency.
From a community psychology perspective, it has been shown that after a certain time of
continuous functioning, RECs enhance - just as other types of cooperatives - the social cohesion
of its members (Pezzini, 2006). This can have significant benefits for the general functioning
of a community and lead to a virtuous cycle of collaboration among its members. Other authors
have found that by being part of a cooperative that successfully implements renewable energy
projects, many members of RECs are significantly more convinced that a decentralized energy
transition is feasible, after having joined the cooperative (Yildiz et al., 2015).
When analyzing the activities cooperatives perform, the REscoop mentions that RECs vary
with regards to the scope of their activities. Accordingly, some only finance projects, while
others are involved in each stage of the project development. Also with regards to operations
and maintenance, as well as commercial handling of the electricity selling, RECs differ
significantly from each other. Few RECs even run their own distribution grids, like the
traditional rural electric cooperatives (Yadoo and Cruickshank, 2010). Finally, according to the
Federation, some RECs exist mainly to supply their members with energy, while others have
the proclaimed aim to act as energy provider for internal as well as external entities. It can thus
be concluded that the scope of activities RECs perform is broad and should be adapted to the
circumstances the cooperative operates in and, most importantly, to the needs of its members.
Having introduced the concept of RECs, in the following it will elaborated on how they can
facilitate the deployment of renewable energies.

2.2 How RECs facilitate the deployment of renewable energies
Walker (2008) poses several reasons why RECs facilitate the deployment of renewable
energies: first, they lead to a higher local acceptance of the technical installations. This is
especially important in the case of wind energy projects, since wind turbines can lead to
significant negative externalities, such as noise pollution, which in certain cases has led to the
protest of the local communities. Second, RECs lead to lower energy costs and a more reliable
energy supply for their members. The cost benefit applies to almost all situations, since
prosumers do not have to pay the profit margins of energy companies and have less grid costs.
The argument of supply reliability applies only to communities suffering from non-existent or
inadequate energy infrastructure. Third, the author argues that RECs help their members to
achieve ethical and environmental commitments, since it allows them to invest in a more
sustainable energy supply, often by procuring green electricity for their own consumption. This
is especially interesting for companies operating in an environment with high CSR aspirations.
Finally, RECs enable its members to perform load management (coordinating energy demand
and supply), which can lead to significant cost benefits as well (Rieger et al., 2016).
Other authors mention the benefit that financial barriers to the deployment of renewables can
be overcome trough RECs (Morris and Pehnt, 2016). This is an important element in countries,
such as the Netherlands, where state funding for renewable energies does not provide a stable,
long term cash flow for renewable power plants (as in the case of i.e. standard feed-in tariffs).
In such circumstances, developers and owners of renewable power plants have difficulties
financing such projects, since the return on investment is unclear. In fact, this is one of the
reasons why the Netherlands currently lag behind in the deployment of renewable energies
(Pieters, 2016). In the case of an REC, however, its members can decide to sign long term power
purchase agreements with the owners of renewable energy power plants, which could mitigate
the problem of future cash flow calculability and provide sufficient financial stability.
Especially at the Port of Rotterdam, where an REC of electricity consuming companies could
lead to the pooling of a significant portion of the entire Dutch national electricity consumption,
a long-term power purchase agreement of such a magnitude would provide a strong signal
towards financial institutions.

Yildiz (2013) names lower danger of opportunistic behavior as one of the main benefits offered
by RECs. Based on the above-mentioned theory of transaction costs (Coase, 1998; Williamson,
2000), the author argues that by giving ownership of their business activities to their members,
cooperatives can be a beneficial organizational structure, since they reduce opportunistic
behavior of the agents and thereby transaction costs. This effect, however, depends on the
transaction specificity of the activity the cooperative performs. Accordingly, it is difficult for
cooperatives performing a highly specific and complex business activity to gain benefits out of
the cooperative organizational structure. This is because business activities that involve a
complex value chain (i.e. bio mass power plants) make it more difficult to distribute ownership
in a way that does impede opportunistic behavior. The author argues further that photovoltaic
energy cooperatives are more suitable for energy cooperatives, since the value chain of
photovoltaic power plants is less complex and thus contains just the right amount of specificity
for a cooperative to benefit from the lower transaction costs cooperative organizational
structures can bring. In other words, because they minimize the cost of market contracting
(hiring external companies) and do not generate too high costs of ownership, photovoltaic
energy cooperatives constitute the most prominent form of energy cooperatives (Huybrechts
and Mertens, 2014). It is thus no surprise that among all RECs registered in Germany in 2013,
69% percent were photovoltaic energy cooperatives (Debor, 2014).
In the preceding subchapter, it has been shown how RECs can help to increase the amount of
solar energy installations by, for instance, lowering financing barriers. Once solar systems are
installed, there is, however, a second important challenge that has to be met: system integration.
Energy cooperatives in general, and RECs in particular, are good vehicles to address this task.
In the following it will be explained how.
2.2.1 Energy cooperatives as power brokers
The research question of this thesis raises the issue on how to increase the deployment of solar
energy at the Port. While, the first reaction to this question is to interrogate how the amount of
solar power plants at the Port could be increased, such a research would only shed light on one
half of the issue. It is true that solutions must be found on how to develop a more sustainable
energy procurement. However, since renewable power plants behave fundamentally different
than conventional power plants (higher volatility etc.), it is expedient to close this subchapter
Moritz Hentschel, 441663 – Master Thesis
13
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
by discussing system integration as another reason why RECs can lead to more renewable
energy deployment.
In fact, in countries where the Energiewende has already profoundly shifted the energy
landscape, such as Germany, integrating renewables into the existing energy system has become
a bigger challenge than increasing the amount of renewable power plants (Bruns et al., 2012).
The current system design of “central power stations serving large populations of customers is
breaking down” (Collins and Ketter, 2014, p. 8), which is why the research community is busy
developing means to create “smart markets” (Bichler et al., 2010, p. 1). Meeting this task will
require large scale measures that include providing “efficient price signals that motivate
sustainable energy consumption as well as a better real-time alignment of energy demand and
supply” (Ketter et al., 2013, p. 1). To develop solutions aiming at better price signaling and
demand-supply alignment, Professor Ketter (Erasmus University), Professor Collins
(University of Minnesota) and Prashant Reddy (Google) have created the Power Trading Agent
Competition (Power TAC), which is an innovative competitive simulation of future retail power
markets. During such simulations, teams act as power brokers to develop solutions that intend
to perform efficiently in an energy system that is defined by decentralization, which leads to
high complexity and volatility. According to the authors, the Power TACs will lead to the
development of powerful, IT based broker agents, which will help modern societies to cope
with the above-mentioned challenge of renewable energies system integration. In fact, first
results of the simulations show that such virtual electricity broker agents (EBAs) can make
energy systems more adapted to the variability of renewable energy supply by providing better
information and incentives than current market designs. Accordingly, in a more complex market
environment, such EBAs can have a positive impact because they “autonomously set
competitive prices, forecast demand with acceptable accuracy, and make explicit use of many
strategic options such as sourcing from small-scale producers” (Ketter et al., 2016, p. 454).
A similar solution that has been proposed is referred to as demand side management (Rieger et
al., 2016; Gottwald et al., 2011). This approach poses that renewable energies can be better
integrated into our energy systems by aligning the electricity demand with volatile power
sources. This can be achieved through smart appliances, such as fridges who turn on only when
electricity production is peaking and thereby act as power buffers and storage. However,
according to the author, purchasing such appliances is currently not economically attractive
Moritz Hentschel, 441663 – Master Thesis
14
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
enough for individual energy consumers, which leads to a low market penetration and
consequently to insufficient buffer capacities. Therefore, Rieger et al. (2016) argue that larger
entities, such as cooperatives, should step in to bundle the energy demand of individual
consumers. In fact, the authors have shown that cooperative demand response can lead to
significant cost savings for customers and providers of energy by achieving a better
coordination of electricity demand and thereby reducing consumption peaks.
Another important part of a solution to demand-supply alignment is the concept of virtual power
plants (Pudjianto et al, 2007), which refers to aggregating many small power plants, such as
roof top solar energy systems, into one bigger system through smart metering and remote
controlling technology. This concept allows, in theory, to manage many scattered, decentralized
power plants in an efficient manner by regulating their output according to the demand in the
market. However, in practice, this concept is far from being a reality, since it requires significant
investment in smart metering and smart regulating infrastructure.
Ketter et al. (2013) name additional measures that can be taken, such as investing in storage
capacity, in electric vehicles or in modern transmission grid infrastructure. It becomes thus
apparent that there are variety of practical solutions available to meet the challenge of system
integration.
To conclude, it must be noted that there is an important underlying aspect that most of these
solutions contain: a successful integration of renewable energies into our energy system can
only be achieved by increased implicit or explicit cooperation among energy producers and
consumers, supply and demand. Consequently, the work of power brokers is crucial in that
regard, because they can set the right incentives to achieve such cooperation. (Ketter et al.,
2013). According to the authors, there are at least three entities that could assume such a power
broker function: energy retailers, utilities or cooperatives.
Having elaborated on how RECs can facilitate the installation as well as the integration of
renewable energy power plants, in the following it will be zoomed in on the topic of solar
energy, which is the research focus of this thesis.

2.2.2 How PECs facilitate the deployment of solar energy
Since the research question of this thesis aims at researching how to increase solar energy
deployment at the Port, it is expedient to have a closer look at RECs that focus on solar energy.
As outlined above, photovoltaic energy cooperatives (PECs) are the most prominent type of
RECs. In the following, this subchapter will portray aspects specific to PECs that have not yet
been covered by previous sections. For the purpose of this thesis, all elements will be
accompanied by a practical example of how it would affect the Port of Rotterdam.
One of the fundamental conditions for the deployment of solar energy is the availability of
suitable space to install the photovoltaic systems. Since policy makers want to limit agricultural
land wasted through free-field photovoltaic power plants, regulators increasingly favor the
usage of roof-top photovoltaic power plants (Neumann, 2014). However, even though potential
investors might be interested in solar energy, they often do not own suitable roof-space. PECs
can help overcome this barrier, because PECs enable a community of participants to jointly
own renewable power plants (Klemisch and Boddenberg, 2015). In the case of the Port this
means that if companies decided to form a PEC, those lacking suitable roof space could still
own a solar energy system that is installed on the roof of another member of the cooperative.
Consequently, through modern smart metering technology, they could produce their own solar
energy on another roof. In addition, strategically located storage facilities that are owned by the
cooperative could further facilitate the usage of solar energy. This effect could help mitigate
the mismatch between electricity consumers and roof owners.
In addition, since roof-top photovoltaic power plants are often limited in size due to a variety
of reasons (statics, unsuitable roofing, wrong inclination), photovoltaic roof-top power plants
generally belong to the smaller generators among renewable energy power plants. However,
through a PEC bigger solar generators can be installed by a group rather than by each member
individually. Consequently, scale effects constitute a crucial reason why PECs facilitate the
deployment of solar energy (Sommerfeldt, 2013). For instance, by pooling roofs and electricity
consumption, a PEC at the Port could lead to the installation of a photovoltaic power plant with
the capacity of several Gigawatts, as well as big strategic storage solutions (i.e. NaS batteries,
which are highly suitable for commercial large scale electricity storage) that help smoothing
solar energy production and peak demand. The sheer size of such a project would decrease
Moritz Hentschel, 441663 – Master Thesis
16
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
installation, operations and maintenance costs significantly, compared to the installation and
operation of smaller solar systems and storage solutions by each company individually.
Yildiz (2014, p. 680) explains why from a technical standpoint photovoltaic roof-top systems
are particularly suitable for energy cooperatives. According to the author, "modularity,
simplicity, high reliability, low maintenance requirements and short lead times" are specific
advantages of solar energy projects, which help groups of relatively small investors to overcome
several investment barriers. Applied to the situation of the Port, where an energy cooperative
would indeed be composed of a variety of relatively small investors (compared to national
energy companies or strategic investors, such as insurances), this implies the following: first,
modularity is important, because the companies at the port do not all have suitable roofs and
therefore it is crucial that the solar panels can be fitted in a flexible manner on different roofs,
thereby splitting the power plant in many small pieces. Solar energy is the only renewable
energy source that offers this benefit. Second, simplicity enables the companies to implement
photovoltaic energy projects without being experts in the renewable energy field and without
having to purchase extensive outside counsel. Third, high reliability is necessary, since this
aspect lowers the investment risk and increases the probability of earning a profit over the long
term. Especially companies (as opposed to individuals) cannot afford to make investments out
of purely ideological reasons and must be presented with a waterproof feasibility study before
making new investment decisions. To reach such sound levels of feasibility for an energy
project, high reliability of the technology used is crucial. Fourth, low maintenance requirements
enable companies to run solar systems while continuing to focus on their core business. Fifth,
short lead times (approximately 1-2 years from decision to switching on, depending on the size)
make it possible for companies to fit solar energy projects into their general short term planning
horizon.
Finally, it is mentioned that PECs are particularly suitable for prosuming activities (Klemisch
and Boddenberg, 2015). Since PECs rely increasingly on roof-top photovoltaic power plants,
the photovoltaic systems they own are often situated in proximity to energy consumers (i.e. on
their roofs), who in turn are often members of the PEC. In the case of the Port this aspect is
particularly relevant, since the companies owning suitable roofs often consume high amounts
of energy or are located in proximity to other energy consumers. Furthermore, the Port harbors
many refrigerated warehouses, which can serve as energy storage systems. This collective
Moritz Hentschel, 441663 – Master Thesis
17
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
organizing of energy production and consumption through a local community of energy
consumers has received the term "collective prosuming" (Klemisch and Boddenberg, 2015, p.
12).
Having elaborated on the concept of renewable energy cooperatives and how they increase the
likelihood of renewable energy deployment in general and of solar energy in particular, the
organizational form of RECs will now be analyzed from a strategy perspective. This will steer
the focus of this research towards RECs composed of companies. In fact, it is pertinent to review
literature on this topic, given that a REC at the Port would be composed of companies and not
of citizens, which is the case for most RECs. Consequentially, by comparing RECs to strategic
alliances, the researcher will be able to better understand the functioning of RECs composed of
companies.
2.3 RECs as strategic alliances
In this chapter, it will be shown how the concept of cooperative organizations can be linked to
the concept of strategic alliances and what can be inferred by applying what is known about
the latter to the field of RECs. Varadarajan and Cunningham (1995, p. 1) define strategic
alliances as “a manifestation of interorganizational cooperative strategies [which] entails the
pooling of specific resources [...] in order to achieve common goals as well as goals specific to
the individual partners."
There are several aspects of this citation that prove why this definition serves well the purpose
of this research: first, as opposed to cooperatives composed of individual citizens, a cooperative
of companies is also an interorganizational endeavor. Second, one of the fundamental aims of
a REC at the Port would be a pooling of resources. Furthermore, such a cooperative would not
lead to an all-inclusive cooperative behavior of the companies located at the port - many
companies are competitors - but to a pooling of specific resources, be it roof space or purchase
and bargaining power, which do not interfere with the balance of competitive advantage within
the port. On the other hand, by decreasing the energy costs and improving the image of all
companies, a REC at the Port of Rotterdam would also strengthen the competitive advantage
of the entire Port. This relates to the final elements of Varadarajan and Cunningham's definition,
as achieving improved competitive advantage towards other ports is clearly a common goal of
the companies located at the port, while decreasing energy costs by buying local solar energy,
Moritz Hentschel, 441663 – Master Thesis
18
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
generating additional income by renting roof space or investing in sustainable assets would be
goals specific to certain individual companies, depending on their properties (high energy
consumers or warehouses owning large roofs etc.).
Also Parkhe's (1993, p. 795) definition of strategic alliances, which the author describes as
"relatively enduring interfirm cooperative arrangements [...] that use resources and/or
governance structures from autonomous organizations, for the joint accomplishment of
individual goals linked to the corporate mission of each sponsoring firm" fits the concept of
cooperatives composed of companies.
Having established that a REC at the Port of Rotterdam would constitute a strategic alliance,
conceptual implications related to the field of strategic alliances will now be presented.
2.3.1 Different levels of integration
According to Varadarajan and Cunningham (1995, p. 283) the strength of linkages companies
form within a strategic alliance can range from complete integration of the entirety of a firm’s
functional areas towards cooperative action that is "limited in scope to a single functional area
and value creation activity". In fact, the authors name two different types of structures a
strategic alliance can form: alliances can either choose to establish a distinct corporate entity
or a distinct interorganizational entity. Both structure types involve sharing skills and resources,
however in the first case, alliance partner also hold equity positions within the alliance. The
authors further mention that since interorganizational entities do not involve direct financial
commitments, they allow for more flexibility.
2.3.2 Motives for strategic alliances
Renewable Energies at the Port, a strong case for a strategic alliance
After having analyzed a variety of authors active in the field of strategic alliances, Varadarajan
and Cunningham (1995) conclude that the main reasons why companies enter strategic alliances
are:
market uncertainty
drive for increased efficiency
resource dependency
skill and resource heterogeneity
imperfect factor markets
Moritz Hentschel, 441663 – Master Thesis
19
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
Viewing these elements in the light of renewable energies at the Port of Rotterdam, the
following can be inferred: first, since the current Dutch renewable energy regulations do not
provide fixed feed-in tariffs, they do not offer strong securities for investments in renewables
and it is unclear when and how this situation might change. Therefore, market uncertainty is
witnessed.
Second, due to high energy prices and increased expectations by consumers, Dutch companies
have a strong drive for increased energy efficiency (Ecofys, 2012).
Third, with regards to electricity, companies at the Port are resource dependent, since they rely
on external energy providers.
Fourth, companies at the port are specialized in many different areas and do not necessarily
own knowledge in the field of renewable energies, therefore there is a skill and resource
heterogeneity.
Finally, as mentioned by the Port Authorities, there is an immense potential for solar energy,
that is not yet used; a clear sign for an imperfect factor market. It can thus be concluded that
each motivating element fits the case analyzed by this thesis.
Resource pooling
Analyzing strategic alliances from a resource dependency theory perspective, Das and Teng
(2000) name the ability to pool resources as an important motivational factor the formation of
a strategic alliance. According to the authors, companies enter alliances because they see a
significant potential for value creation when they pool their resources together.
The authors further stress that if the resources to be pooled are imperfectly mobile (e.g. roofs)
and imitable (e.g. bargaining power regarding electricity consumption), they offer more
potential of value creation through cooperation.

2.3.3 Propensity to enter strategic alliance
In their highly instructive work, Varadarajan and Cunningham (1995) also describe internal and
external factors that incite companies to form strategic alliances (Figure 1).
Figure 1 - Factors influencing the Propensity of a Firm to Enter Strategic Alliances
The authors name three categories of characteristics that have an influence, namely: firm
(internal), industry and environmental characteristics. The - for this research - most relevant
characteristics will be pointed out in the following: firm size and resource position influences
a firm's propensity to enter an alliance, since the more resource independent it is (or feels), the
less it sees will be willing to enter an alliance and pool its resources. Prior involvement in
strategic alliances and top management attitudes affects a firm's propensity to cooperate, since
trust among top level management will help to share knowledge and resources with other
companies. A highly important factor in the case at hand is minimum efficient scale. Certain
Moritz Hentschel, 441663 – Master Thesis
21
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
projects within an industry require a sufficient scale to become feasible. This can be achieved
by pooling resources, for instance through a cooperative. Furthermore, the threat of competition
from substitutes may play an important role for the Port, since there is constant competition
with other major ports such as the port of Hamburg (Notteboom and Yap, 2012). As argued
above, there is also a significant market uncertainty related to renewable energies due to an
unstable and to some extend unfavorable political, legal and regulatory environment in the
Netherlands.
Having steered the research focus towards RECs composed of companies by analyzing the
concept of strategic alliances, in the following the notion of energy clusters will be introduced.
This topic will complete this literature review, since understanding the concept of energy
clusters will help the researcher embed the concept of RECs within the Port of Rotterdam.
2.4 Clusters - a fertile ground for cooperatives
Different from strategic alliances, which develop out of the decision of companies to share
resources and to cooperate in order to achieve a common goal, clusters refer to the
circumstances in which companies operate. Elaborating on the notion of clusters will give the
reader a better understanding of the industrial zone at the Port of Rotterdam and provide
additional support on why the Port could be a fertile ground for an energy cooperative.
In a visionary article on competition in a globalized world, Michael E. Porter (1998) introduces
the concept of clusters. According to the author, clusters are "geographic concentrations of
interconnected companies and institutions in a particular field" (Porter, 1998, p. 78). Porter
argues that, since companies can nowadays source globally, competitive advantage is shifting
from having access to certain inputs to making more productive use of the resources a firm
sources. Consequentially, the "immediate business environment outside companies plays a vital
role" (Porter, 1998, p. 78). Porter further argues that this environment should be viewed in a
broad sense and include institutions such as universities, which support companies in their
proximity to remain competitive (such as the University of Rotterdam intends to support the
Port of Rotterdam through the research at hand). In the article, it is stated that clusters can exist
in competitive environments and that they are in fact able to "promote both competition and
cooperation [emphasis added]" (Porter, 1998, p. 79). Porter explains that within a cluster
"competition can coexist with cooperation because they occur on different dimensions and
Moritz Hentschel, 441663 – Master Thesis
22
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
among different players" (Porter, 1998, p. 79). Since companies that coexist within a cluster are
situated in close proximity, there is a lot of exchange among them, which in turn fosters trust.
Putting emphasis on the fact that competitive advantage in modern times is achieved through
greater productivity, Porter argues that companies must achieve sophistication in the way they
produce goods and services, which in turn is highly dependent on the local business
environment they act in. Therefore, executives should expand their focus of attention from
matters internal to their firm and to their industry towards the situation of their cluster, because
"a vibrant cluster can help any company in any industry compete in the most sophisticated ways,
using the most advanced, relevant skills and technologies", such as renewable energies (Porter,
1998, p. 86). According to Porter, one of the main benefits clusters offer to its members is that
they allow "each member to benefit, as if it had greater scale or as if it had joined with other
formally" (Porter, 1998, p. 80). It can thus be argued that a cluster constitutes a fertile ground
for cooperatives, since it builds up an environment of trust and beneficial interdependence
among companies located in close proximity.
Having established this, one could ask whether Porter would consider the Port of Rotterdam as
a cluster. Interestingly, in his article the author answers this question himself (Porter, 1998, p.
84):
"A cluster’s roots can often be traced to historical circumstances. [...]. The Dutch
transportation cluster owes much to Holland’s central location within Europe, an extensive
network of waterways, the efficiency of the port of Rotterdam, and the skills accumulated by
the Dutch through Holland’s long maritime history."
Furthermore, in its 2014 report on the Dutch energy policies, the International Energy Agency
goes even further by directly calling the Port of Rotterdam an energy cluster (IEA, 2014, p.
168).
It can thus be concluded that there is evidence in academic and professional literature stating
that the Port of Rotterdam can be identified as a cluster. According to Porter this might set the
ground for a competitive environment where cooperation in certain dimensions is nevertheless
possible, which leads to the concluding assumption that due to its energy cluster characteristics,
the Port might be a fertile ground for the genesis of an energy cooperative.

2.5 Literature summary
In this chapter, the research has been prepared through a literature review divided in four
subchapters: first, the topic of (renewable) energy cooperatives was introduced. Second, it was
explained how cooperatives can serve as facilitators to increase the procurement of renewable
energies and as system integrators once renewable energies become a part of the energy mix.
Third, RECs composed of companies have been analyzed by presenting the concept of strategic
alliances. Finally, the notion of energy clusters has been introduced to help the reader
embedding the concept of RECs within the Port of Rotterdam.
To explain how these four topics are related and to outline the underlying logic of this thesis, a
literature summary model has been developed (Figure 2). There are two assumptions driving
this model:
Assumption 1
The main assumption of this thesis is that founding a REC composed of companies at the Port
of Rotterdam is expected to increase the likelihood of solar energy deployment at the harbor.
Assumption 2
The second assumption is that an energy cluster at the Port of Rotterdam would increase the
positive impact of the first assumption by providing a fertile ground for cooperation regarding
energy topics.
Figure 2 - Literature summary model
Moritz Hentschel, 441663 – Master Thesis
24
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
However, while in theory it seems easy to comprehend the above shown model, gauging its
correlations through empirical research is not as straight forward. The problem is that since
there is no REC established yet at the Port, there is no data available to measure the above
shown assumptions. It would also be difficult to gather new data on the correlations, since there
is currently no understanding among the stakeholders at the Port about how an REC at the
harbor would be designed and how it would operate.
Consequently, this model can only serve as a visualization of the general idea on which this
thesis is based. To capture the actual aim of the research at hand, a more detailed research
framework will be presented now.
3 Research framework
In this chapter the research framework of this thesis will be outlined. The research framework
aims at presenting the theoretical concepts and the interactions that are pertinent to the research
question. It will thereby help the reader to better understand the research strategy and eventually
the results (Miles and Huberman, 1994).
Figure 3 represents the research framework. Through this framework, it becomes clear that the
goal is to find out, which characteristics a REC at the Port should contain to increase the
likelihood of solar energy deployment at the harbor. In other words, it will not be measured
how strong the impact of the independent variable is on the dependent variable, but how the
independent variable should be designed to have a positive impact on the dependent variable.
According to the researcher, such a research objective is pertinent in the case at hand, where
there is no data available and theory must be built from scratch. In the following, the research
framework will be explained in more detail.

Figure 3 - Research framework
The figure must be read from left to right. Each topic has been assigned to its respective chapter
or subchapter of this thesis. The left dotted circle contains all the elements of the framework
that will be researched first and the right dotted circle contains all elements that will be
addressed in the second research phase. In the right dotted circle, the literature summary model
is presented, depicting the independent and dependent variable as well as the moderator.
In the following, each concept and interaction will be elaborated on. The goal of this explanation
is twofold: first, it will help the reader to understand the reasoning of this thesis. Second, it will
help to better comprehend the research methodology that will be outlined in the next chapter.
3.1 Existing cooperatives as guidance
The dotted circle on the left serves as foundation for independent variable. There are three
important elements that lead to the independent variable: first, RECs are the starting point of
this thesis and will therefore serve as initial data source. Second, this thesis postulates that RECs
have common characteristics. Third, it is assumed that these characteristics can be identified by
researching the motivation and goals of existing RECs, their history and founding processes as
well as challenges they faced and recommendations they can give.

3.2 The right characteristics of RECs lead to solar energy deployment at Port
The starting point of the second research phase is the box called most fitting characteristics.
This element has been highlighted, because it constitutes the centerpiece of this research.
Identifying these characteristics is the main goal of this thesis and it will be achieved by filtering
the common characteristics identified in the first research phase depending on their likeliness
to have a positive effect on solar energy deployment at the Port. The filtering process is what
connects both research phases, therefore it is placed in both dotted circles. The likeliness to
have a positive impact has been introduced in subchapter 2.2 and is depicted in the research
framework using a white arrow to the right of the most fitting characteristics.
It is proposed that by identifying common characteristics of existing RECs and filtering them
according to their fitness to have a positive impact at the Port, an effective action plan on how
to launch a REC at the harbor can be recommended, which can facilitate the deployment of
solar energy. Accordingly, the dependent variable of the framework – solar energy deployment
at the Port of Rotterdam - is expected to be positively influenced by a REC that contains the
right characteristics.
3.2.1 A fertile ground for a cooperative at the Port
Finally, the energy cluster above the white arrow represents a moderator to the effect of a REC
on the deployment of solar energy at the Port. The framework postulates that due to the
existence of an energy cluster at the Port, companies within the harbor area might be more
inclined to pool resources, such as roofs and purchase power to become part of a more efficient
and competitive ecosystem. Consequentially, the existence of a cluster must be taken into
account when designing the energy cooperative to fully exploit the positive moderating effects
it can have on the deployment of solar energy.
3.3 Chapter summary
To conclude, the research framework proposes that a successful emergence of a REC at the Port
will depend on the characteristics of its organizational design. Therefore, already existing
cooperatives should be analyzed to define common characteristics, which should be tested in
the Port context and thereby enable the researcher to develop a theory on how a REC at the
harbor should be designed. Additionally, the framework proposes that an energy cluster at the

Port of Rotterdam could enhance the positive effect of a REC on solar energy deployment.
Therefore, it should be researched, how the REC should be designed to fully exploit the positive
effects of this moderator.
Having presented the research framework, in the next chapter the appropriate methodology and
research process design will be presented. The design is intended to act as a framework to guide
the research through the operational process of this thesis.
4 Methodology and research process design
4.1 Methodology
In the following the methodology of this study will be presented. The research onion (Figure
4), developed by Saunders and Tosey (2012), will serve as guidance to depict the research
design.
Before starting to apply this tool, it is expedient to recall the goal of the research question, since
the methodology of a research should be designed in accordance with the general research goal
(Mackey and Gass, 2015): the aim of this research is to find out, what characteristics a potential
REC at the Port of Rotterdam should possess, to facilitate solar energy deployment at the
harbor. This research goal features three important aspects: first, it is highly specific and seeks
Figure 4 - Research Onion
Moritz Hentschel, 441663 – Master Thesis
28
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
a concrete answer that aims at being implemented. Second, it asks for data that is gathered from
existing RECs and that has its source in their practical experiences. Third, it aims at developing
a theory about a phenomenon that does not exist yet, since a REC at the Port is yet to be
established.
4.1.1 Research philosophy and methodical choice
This research will analyze “social phenomena in their natural environment” (Saunders and
Tosey, 2012, p. 58). Therefore, it will be embedded in the research philosophy of interpretism.
According to Saunders and Tosey, interpretism is often accompanied by a qualitative research
methodology, because it aims at analyzing specific phenomena through in-depth analysis and a
small number of samples.
The study at hand has exactly this intention, as it aims at developing a theory on the specific
case of a REC at the Port of Rotterdam. Therefore, a qualitative research methodology will be
chosen; a multimethod qualitative method to be more precise, since both interviews and desk
research will be conducted.
4.1.2 Research strategy
The next layer to be defined relates to the research strateg(ies). For the purpose of this research,
it is highly fitting that Saunders and Tosey named this layer strateg(ies), implying that more
than one strategy can be used. As we will see in the following, both case studies as well as
grounded theory would be highly fitting research strategies for this thesis.
In fact, since establishing an energy cooperative at the Port of Rotterdam is a new idea that has
not yet been implemented, there is no specific data available that the researcher could use to
answer the research question. In addition, this research aims at providing results that can be
directly applied. Hence, the researcher should make use of a research strategy that allows him
to gather new data from real live phenomena, enabling him to transfer these insights to the Port
of Rotterdam. Given these prerequisites, it is expedient to apply a case studies research strategy,
which is a suitable strategy to gather transferable information on already existing, real live
phenomena (Yin, 1994).
Moritz Hentschel, 441663 – Master Thesis
29
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
However, due to the lack of existing data and information regarding where to start the research
and what to research, the research strategy must be flexible enough to allow the researcher to
pivot during the process and to react to insights gained throughout the case studies. Therefore,
a step by step research method that progressively reveals information about where to continue
researching, appears to be crucial. This “continuous cycling between empirical data collection
and data analysis” (Steenhuis and De Bruijn, 2006, p. 5) calls for a grounded theory approach,
instead of a case study research strategy. In fact, when trying to develop a theory that is highly
practical and close to reality, such as in the case of this study, grounded theory might be just
the right approach (Glaser and Strauss, 1967).
Consequently, choosing among these two highly fitting strategies would be difficult. Luckily,
Steenhuis and De Bruijn (2006) follow Saunders’ and Tosey’s indication that several strategies
can be combined by proposing a research strategy that merges case studies into grounded
theory: the progressive case study. According to the authors (Steenhuis and De Bruijn, 2006,
p. 7), the goal of the progressive case study is to
“outline an inductive (theory developing) case-study approach that is oriented in the
interpretivist paradigm where the outcome is some theory that should not be considered
validated but rather it contains concepts and possible relationships which creates new insight
(grounded in empirical data) and that can be tested in subsequent research.”
There are several aspects of this citation that have to be highlighted. First, Steenhuis and De
Bruijn classify their strategy within the interpretism paradigm, which is consistent with the
research philosophy chosen for this study. Second, the authors state that a progressive case
study does not aim at generating a theory that is immediately validated, but which must be
tested in subsequent research. This perfectly fits the goal of the study at hand, since the only
way to validate the theory created by it will be by launching the REC according to the
recommendations given at the end of this research and then analyzing the results of the literature
summary model outlined in Figure 2. Since there has never been a REC at the Port, it is difficult
to build a theory that is validated any other way. Third, Steenhuis and De Bruijn’s research
strategy aims at generating new insights based on grounded empirical data, gathered through a
case-study approach. Consequently, this strategy enables the researcher to reevaluate his
approach case after case, which gives him the necessary flexibility in a context where very
Moritz Hentschel, 441663 – Master Thesis
30
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
limited to no starting information is available and where the entire theory must be built from
scratch, based on insights gathered throughout each case. It can thus be concluded that the
progressive case study strategy is a fitting method for this study, since each case will provide a
piece of the puzzle and steer the researcher in directions that he might not even be aware of
when starting the research.
An additional benefit of this approach is that by progressively advancing in the research, the
researcher can test initial results gained through the first cases within subsequent cases. Thereby
he will be able to confirm or discard results gained along the way by finding different sources
that validate the same data. This technique, called triangulation, increases the credibility of the
findings significantly (Steenhuis and De Bruijn, 2006). For instance, if the first case reveals that
professionalism is an important characteristic for the success of an energy cooperative, this
result can significantly gain in validity if the next case, whose study population is completely
independent from the first case, reveals the same information.
4.1.3 Time horizon and data collection method
Regarding the time horizon of the research, a cross-sectional approach will be chosen. This is
because this study aims at answering a question at a given moment in time: what is now the best
way to launch a REC at the Port of Rotterdam? According to Saunders and Tosey, cross-
sectional approaches are suitable for such questions and normally involve case studies, which
validates the above presented choice of the research strategy. Since an in-depth research of a
limited number of specific cases is required, interviews have been chosen as the adequate data
collection method.
Having defined the research strategy, in the following the research process design will be
presented. The aim of the research process design is to achieve transparency by explaining what
research steps will be taken and how these steps intend to eventually enable the researcher to
answer the research question.
4.2 Research Process Design
Figure 5 depicts a graphical representation of the research process design. Due to the
progressive case study strategy, the research will be composed of three consecutive cases
Moritz Hentschel, 441663 – Master Thesis
31
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
enabling the researcher to progressively build a theory that is grounded in the findings gathered
throughout the cases.
Steenhuis and De Bruijn (2006, p. 12) argue that “more inductive and interpretism oriented case
studies are generally considered of less quality than testing oriented designs.” Accordingly, to
assure a high research quality, a testing oriented research design that allows for triangulation
has been chosen. It will take the form of a two-phase approach with a total of five research
steps. This approach will allow the researcher to gather first results in research phase I (step 2),
which can then be validated (step 3) and if necessary revised (step 4) in research phase II.
Figure 5 - Research Process Design
In the following, each research phase will be explained in detail.
4.2.1 Phase I
Phase I is composed of two steps. The first step contains two case studies and aims at
understanding RECs in general. In the first case study, German RECs and in the second case
study, Dutch RECs will be researched. For both case studies, desk research on recent
Moritz Hentschel, 441663 – Master Thesis
32
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
developments regarding energy cooperatives and RECs will be conducted. Furthermore,
members of existing RECs will be interviewed. Their legal structure, business models and
organizational designs will be analyzed in order to understand their raisons d’être, functioning
and the issues they are facing.
In the second step of Phase I, common characteristics of RECs that have been progressively
identified throughout the two first case studies will be gathered.
4.2.2 Phase II
Having carved out these results, the second phase aims at identifying those characteristics of a
REC that fit the purpose of facilitating solar energy deployment at the Port of Rotterdam. These
most fitting characteristics will be composed of two different types of results. First, they will
be constituted of characteristics that have been named in phase I and confirmed in phase II.
These characteristics will be called confirmed characteristics. The second constituent of the
most fitting characteristics will be new characteristics that are proposed by the stakeholders
interviewed in phase II. These characteristics will be called potential characteristics.
To achieve this, three additional research steps will be taken. In the third step, a third case study
will be conducted. This final case study aims at investigating the opinion of decision-makers
within companies and other crucial stakeholders at the Port (i.e. the port authorities) on the
matter of solar energy and collaboration trough energy cooperatives. The primary data
collection method will be interviews. In addition, this case study will contain in-depth research
regarding the legal prerequisites a REC at the Port would have to fulfill to be effective as well
as possible business models it would have to put in place.
Interviews of this research phase will also contain questions regarding the existence of an
energy cluster and the general feasibility of a REC at the Port to gather insights on the
underlying literature summary model of this thesis.
Having collected this data, in the fourth step the most fitting characteristics a REC would have
to possess to be successful at the Port will be identified. Additionally, insights concerning the
second assumption of the literature summary model, namely the moderating effect of an energy
cluster on the positive impact of a REC on solar energy deployment, will be presented. Finally,
Moritz Hentschel, 441663 – Master Thesis
33
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
based on these results, in the fifth step a REC design will be proposed and practical
implementation recommendations will be provided.
4.3 Study population
The progressive case study methodology allows the researcher to adapt his research strategy,
including the study population, regularly throughout the research. This way the researcher can
react to indications given by the cases he analyzes. Consequently, the researcher will choose a
certain case as starting point for his study, which, since it will significantly influence the
following pace of the study, must be chosen with care (Steenhuis and De Bruijn, 2006). After
having analyzed this case, subsequent cases to be studied will be chosen depending on “what is
already known, which concepts provide promising new insights, which concepts need further
development, how much theoretical saturation already occurred, and what kind of practical data
is available” (Steenhuis and De Bruijn, 2006, p. 9). This sampling method is called snowball
sampling (Miles and Huberman, 1994) and fits well the purpose of the thesis at hand.
Consequently, the following sampling strategy will be chosen: in accordance with the above
mentioned research framework (Figure 3) and research process design (Figure 5), there will be
three study populations, one for each case.
4.3.1 Case 1
German RECs will constitute the first case and hence the first study population. German RECs
have been chosen as the starting point for this research for two reasons: first, they are at the
forefront of the contemporary energy cooperative movement and second, the cooperative
environment in Germany is comparable to the one in the Netherlands (Schenk, 2013).
Consequently, analyzing German RECs will lead to a rich pool of information that can be well
transferred and compared to the Dutch REC movement. Furthermore, due to the researcher’s
working experience in the German solar energy industry, he has good access to the German
REC network.
As mentioned above, the first case study must be initiated by a study object that has been
selected carefully. Hence, as a starting point of the research, a well-established and well
connected REC should be chosen to provide sufficient insights to steer the subsequent research
in the right direction.
Moritz Hentschel, 441663 – Master Thesis
34
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
4.3.2 Case 2
The study population for the second case will be Dutch RECs. The Netherlands have been
chosen as a research location to enable the researcher to gather information that is specific to
the environment of the Port.
As a rule regarding the study populations of case 1 and 2, cooperatives should have companies
(juridical persons) or their CEOs among its members and own photovoltaic power plants to
qualify for the study. Additionally, interviewees should be founding members of the
cooperatives.
4.3.3 Case 3
In research phase II, the environment within the Port of Rotterdam will be researched as well
as the legal and economic circumstances regarding RECs in the Netherlands. Therefore, the
study population of the third case will be composed of companies located at the Port of
Rotterdam and of other relevant stakeholders (i.e. the port authorities and banks). Interviewees
for case 3 should be as high ranking within the corporate hierarchy as possible in order to
provide rich insights into the strategy of their organizations.
4.4 Data collection
In the following, the practical and technical aspects of the data collection will be discussed.
Figure 5 shows that there are two main types of data collection techniques within each case
study: desk research and interviews. The results of the interviews will constitute the primary
data source for this thesis, whereas the insights gained through the desk research will help
preparing for the interviews and collecting in-depth knowledge about crucial information
gained through the interviews.
4.4.1 Desk research
Desk research in step 1 will allow the researcher to gather background information regarding
the general topic of energy cooperatives. According to Steenhuis and De Bruijn (2006, p. 8)
this is important to enable the researcher to become „sensitive to important areas in the
substantive field which allows the researcher to direct the case study data collection in
promising areas”. In step 3, desk research will enable the researcher to gather in-depth
Moritz Hentschel, 441663 – Master Thesis
35
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
knowledge regarding specific topics that he found out to be crucial based on the results gathered
in research phase I. This will include an analysis of the legal framework regarding energy
cooperatives in the Netherlands as well as their bylaws and business models.
Since the progressive case study methodology is influenced by the grounded theory method,
the desk-research will be in constant exchange with the interviews and its primary goal will be
to provide supporting information to the insights gained through the interviews. Accordingly,
to allow a continuous theory building, both the interviews and the scope of the desk-research
must be adapted to the results gathered throughout the research process.
4.4.2 Interviews
Research steps 1 and 3 represent the more practical research in the form of interviews. For both
steps, a starting semi-structured interview design will be constructed. Two important aspects
concerning this interview design should be highlighted.
First, the initial interview designs will be explicitly called starting designs to allow the
researcher to adapt the design depending on the results gathered throughout each case. This
flexibility is a prerequisite for the progressive case study methodology, which, according to
Steenhuis and De Bruijn (2006, p. 8), requires a “continuous cycling between data collection
and data analysis. In every single case, the data that is collected next is determined by the
analysis of the previous data, i.e. on a day-to-day basis“.
Second, the interviews will be semi-structured, to give the interviewee enough space to
elaborate on his answers - which is crucial for a rich qualitative research - while at the same
time making sure that all necessary elements are addressed. For the interviews of step 1 this
means that the topics motivation and goals, history and processes, recommendations and
challenges have to be tackled. Which topics will have to be addressed in the interviews of step
3 depends on the results of research phase I, but they should in any case include the topics
alliances and clusters.
Each interview will be either conducted in a face-to-face meeting or via phone and will have a
duration of 45 to 60 minutes. If possible, the setting for the interview will present as little
distraction as possible, such as the office of the interviewee. Notes will be taken by the
researcher during the interview in written, stenographic form and if the interviewee agrees, the
Moritz Hentschel, 441663 – Master Thesis
36
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
conversation will be taped. As an introduction to each interview, the purpose of the study will
be explained. Additionally, each interviewee will be informed that her/his name will not be
published; with regards to the name of the organization she/he works for, the interviewee will
be given the choice to keep this information confidential.
After each interview, the stenographic notes will be transcribed into more detailed notes, if
possible with the help of the taped conversation. This will enable the researcher to transcribe
while he is still under the direct impression of the interview, which will help him capture the
entirety of the information provided by the interviewee. Furthermore, each transcript will be
validated by the interviewee. Finally, if the researcher feels that, due to new insights he
gathered, the current interview design does not any longer address all necessary elements that
should be researched, the interview design will be adapted.
The researcher will try to visit as many interviewees as possible in their offices (both in
Germany and the Netherlands), since interviewing them in their environment will help create a
better understanding, which is an important aspect of the research philosophy of interpretism
(Saunders and Tosey, 2012). Due to the nationality of the researcher, the interview language
will be either German or English. In Appendix 1 and Appendix 2 the designs of both research
phases can be found. In accordance with the progressive case study method, the second
interview contains many insights gained in research phase I to confirm characteristics that have
been identified in the first research phase.
4.5 Data Analysis
In order to analyze the data, a predominantly descriptive coding technique will be applied. This
means that the researcher will assign a certain label to each answer of the interviewee by
summarizing its main idea (Saldaña, 2015). This labelling will enable the researcher to assign
each answer to a certain concept. For instance, if an interviewee states that a cooperative must
be professional to be successful, this answer receives the label professionalism. In a second
step, these labels will allow the researcher to code the interviews and to identify recurring or
diverging concepts among the interviews. In certain cases, where the interviewee provides an
answer in a way that is difficult to label in a more efficient or telling way, the researcher will
resort to the in vivo coding technique, which refers to directly extracting the words used by the
Moritz Hentschel, 441663 – Master Thesis
37
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
interviewee (Saldaña, 2015). These excerpts will then be displayed in the results section to
directly transmit to the reader the opinion of the interviewee.
In accordance with the progressive case study method, the coding will evolve progressively
throughout the research process. Consequently, in Phase I it will allow to identify common
characteristics among RECs and to identify other recommendations that can be deduced from
the results. In Phase II, the coding will enable the researcher to confirm, which of these
characteristics regarding RECs and other recommendations would indeed have a positive
impact in the case of the Port. Since initial results will thereby be tested by subsequent results,
this process will lead to triangulation, which will increase the reliability of the findings. More
information on data verification techniques will be presented in the next subchapter.
4.6 Data verification
In the following it will be explained how results will be verified. Since qualitative research can
quickly fall prey to a cognitive bias of the researcher (Chenail, 2011), Steenhuis and De Bruijn
(2006, p. 8) argue that he has to “build” credibility of the findings. Given the importance of
achieving high credibility levels for the research results, in this thesis two data verification
techniques will be deployed: triangulation and validation.
4.6.1 Triangulation
Steenhuis and De Bruijn (2006, p. 8) name triangulation as the main tool to “build” credibility.
They define triangulation as using “multiple data sources or methods” to research a certain
phenomenon. Once a certain result is provided by different data sources and methods, it
increases in credibility. Consequently, the more independent data sources and methods lead to
the same result, the more credible the finding.
The research process design of this thesis (Figure 5) has been crafted to facilitate triangulation.
First, two research phases will allow to gather data from a heterogeneous sample population.
Consequently, in many cases it should be possible to find several interviewees from diverging
backgrounds that independently form each other name the same characteristics. Second, two
different data collection methods will be applied, which will lead to two different types of data
sources: interviews and desk research. This should enable the researcher to test, whether
testimonies given by interviewees can be verified by secondary data that will be assembled
Moritz Hentschel, 441663 – Master Thesis
38
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
through the desk research. Third, the results of this thesis will be ranked according to a grading
mechanism that is based on triangulation. The more interviewees lead to a certain finding, the
higher the grade of this finding. This intends to allow the reader of this thesis to comprehend
how a certain result has been gained and how strong its credibility is.
4.6.2 Validation
The second data verification technique will consist of validation, which refers to confronting
participants with the data gathered. Also in this case, the research process design was crafted to
cater to this verification technique. Accordingly, two research phases will allow to gather data
in the first phase that can then be tested in the second phase. Furthermore, applying the
progressive case study will lead to “continuous cycling between empirical data collection and
data analysis” (Steenhuis and De Bruijn, 2006, p. 8). This will enable the researcher to adapt
the interviews throughout the research, which will allow him to test certain information gained
in an interview by confronting ensuing interviewees with this information. Thereby, targeted
testing of specific insights through validation will be possible.
4.7 Chapter summary
In this chapter, the research methodology has been outlined. This included information on the
research philosophy, methodical choices, the research strategy, the research time horizon and
the data collection method. Additionally, the research process design has been presented as well
as the different study populations. Finally, data collection, analysis and verification methods
have been depicted. Having presented the methodology of the research, its findings will be
outlined in the following chapter.

5 Research findings
The literature review, presented in Chapter 2, touched on renewable energy cooperatives on a
micro level and on cooperatives as part of a bigger system of alliances placed within an energy
cluster on a macro level. To satisfy both the micro and the macro level perspective of the
research, both RECs as well as the environment in which a REC would be placed at the Port of
Rotterdam were analyzed. This approach helped to shed light on the relationships between the
main elements of this thesis that have been displayed in the Research framework in Chapter 3.
As mentioned in Chapter 4, the main data source for this thesis are the interview results, the
results of the desk research serving as support information. Consequently, this chapter will
focus on displaying the research findings of the interviews. First the three cases that constitute
the data pool of this resource will be presented. Second, the results that were coded from these
cases will be outlined.
5.1 Case descriptions
Throughout this research a total of 18 interviews have been performed. Table 1 provides an
overview about how these interviews were distributed among the cases and which types of
organizations have been analyzed in each case. In Appendix 3 a more detailed list of the
interviewees can be found.

content will be given. The interviews will be grouped by case. In accordance with the
progressive case study methodology, the interviews will be presented in chronological order to
Moritz Hentschel, 441663 – Master Thesis
40
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
allow the reader to comprehend the gradual evolution of the insights gained throughout the
research.
5.1.1 Case 1
Case 1 contains the data gathered on German RECs. The research framework (Figure 3) will
serve as framework for presenting the findings. Accordingly, after a brief introduction of the
REC, first the motivations and goals that lead to the founding of the cooperative will be
described. Second, the founding process will be shortly depicted. Third, the main challenges
that the REC faced will be outlined. Fourth, the answers of the interviewee regarding the most
defining characteristics of her/his cooperative will be presented. Each interview will be closed
by presenting her/his recommendations concerning potentially beneficial characteristics of a
hypothetical REC at the Port of Rotterdam.
The attentive reader will notice that the first interview does not disclose any information
regarding challenges that the REC faced. The reason is that the question on challenges has only
been added to the interview after having analyzed the results of the first interview which lead
to the observation that the topic challenges should be included in the research. This is a good
example of the progressive case study methodology, which calls for a “continuous cycling
between empirical data collection and data analysis” (Steenhuis and De Bruijn, 2006, p 8).
Interview 1 - REC Heidelberg
The REC Heidelberg was founded in 2010 and is one of the most innovative German energy
cooperatives; in 2014 it was honored with the German solar energy price. Due to a strong
network within the German energy cooperative movement, this REC has been chosen as starting
point for the progressive case study. The interview was conducted with one of the co-founders
in his office.
The motivation that lead to the founding of this REC was a strong interest in the business model
of producing and selling electricity through collectively owned solar energy power plants and
later on, the societal change that can be brought through it. Furthermore, the founders
appreciated the democratic aspect of the cooperative model. The goal of the cooperative was to
develop as many renewable power plants as possible, financed directly by interested citizens or
companies.
Moritz Hentschel, 441663 – Master Thesis
41
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
The founding process was initiated by four students sharing the above-mentioned goals. First,
they designed together the necessary elements for the founding (business plan, bylaws etc.),
then they searched for more interested people and invited them to a founding event, during
which the founding documents were signed and membership was awarded. After the founding
event, most of the members did not take on operational tasks and the managing core of the four
founders had to assume all the work. Companies joined the REC later, when the cooperative
could prove that its concept worked by successfully installing some first rooftop solar energy
projects. The reason for companies to engage was either that renewable energy fitted their
strategy (municipal utilities pushing for more renewable energy within the municipality) or
because they could use the cooperative for business development purposes (i.e. banks becoming
members to finance the activities of the cooperative). A notable observation is that members of
the REC mainly entered because membership offered attractive investment opportunities, but
as soon as the cooperative started functioning well, these members would start to lobby for a
more sustainable energy system. In addition, it should be noted that the one man one vote rule
established a high level of trust among the members.
The following characteristics define the REC Heidelberg: first, the cooperative is tailored to
the local needs of its stakeholders. For instance, one of its members is a social housing company,
for which the REC developed a model that allowed the tenants of the social houses to make use
of a shared rooftop solar energy plant. Second, its founders showed entrepreneurial spirit and
courage to overcome the initial barriers every business endeavor faces. Third, the cooperative
was professionally managed from the beginning, meaning that the cooperative could pay the
managing directors a salary. Fourth, the cooperative engaged in a political dialogue with
regional and national administrations to influence renewable energy policy making.
Finally, the following potential characteristics of a cooperative at the Port have been
recommended by the interviewee: first, since the Port harbors not only an abundancy of roof
space, but also a lot of energy consumption, the cooperative should make use of smart
prosuming models. Additionally, it must work efficiently, which means that members should
not have to put too much effort into the smooth operational functioning of the cooperative.
Therefore, the cooperative should be professionally managed, maybe even by an independent
entity. Second, the business model of such a cooperative must be well designed to balance the
potentially diverging interests of three groups of stakeholders: renewable electricity consumers,
Moritz Hentschel, 441663 – Master Thesis
42
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
energy producers and roof owners. Third, the interviewee recommended to design the
cooperative with the active participation of each founding member. Further, the cooperative
should not have too many founding members (not more than 8-20). Fourth, from the beginning
a clear organizational structure should be outlined. In addition, the managing director should
be chosen with care, because experience has shown that he/she will have to assume most of the
tasks. Finally, throughout the REC’s entire lifetime, full transparency has to be exercised
towards all members.
Interview 2 - REC Helmetal
The REC Helmetal was founded in 2013, based on a master thesis on sustainable energy
systems written by a student of the local university. The interview was conducted on the phone
with this student who is now one of the founding members.
Generating an additional income for the region by renting out roofs and providing attractive
financial investment opportunities for its citizens served as main motivation for the founding of
the REC Helmetal. Furthermore, in 2013 RECs were highly popular in Germany, which helped
motivating stakeholders.
Four people were involved in the founding process. Each co-founder was chosen because of a
certain benefit he/she would bring to the team (lawyer, mayor etc.). Then, this team prepared a
small business plan and the bylaws and presented this to 17 potential founding members in an
initial meeting. During this gathering, each member paid 500 € membership fee, thereby
receiving membership status and access to the cooperative.
The interviewee mentioned certain challenges that the cooperative encountered along its way.
In the beginning, establishing trust between the members and the management of the
cooperative was challenging, since the management team is significantly younger than the
average age of the members. Additionally, managing an energy cooperative was time-
consuming but had to be mostly assumed by volunteers.
According to the interviewee, the following characteristics define the REC Helmetal: first, the
cooperative collaborates closely with the regional administration. This facilitates the project
development and establishes trust between the local citizens and the cooperative. Second,
companies are not involved as juridical persons, but rather via their CEOs, which eventually
Moritz Hentschel, 441663 – Master Thesis
43
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
has the same impact, since the CEO can influence the decisions of his/her company significantly
and thereby involve the company in the REC as if it was a member. Third, there are roof owners
among the members of the cooperative, since this allows them to not only rent their roofs to the
REC (which they could do also as a non-member), but also to purchase the solar energy that is
produced by the cooperative on their roof. Finally, the REC has no external investors, since this
is difficult to organize due to national legislation on cooperatives.
Finally, the following potential characteristics of a cooperative at the Port have been
recommended by the interviewee: first, the cooperative should have a big outreach from the
beginning, meaning that as many Port companies as possible should be informed about the new
REC and its vision. Accordingly, the name of the cooperative should be inclusive and match
the local spirit of the Port. In fact, the cooperative should rather be seen as an industry
association with investment opportunities in energy projects. Second, a REC at the Port should
analyze in detail the consumption patterns of port companies to understand how the energy
procurement at the Port is organized and what synergies can be created. Third, the founding of
the cooperative should be organized in a small circle of stakeholders who have a concrete
project in mind that can help orientating the founding process. Additionally, the founding
members should be provided from the beginning with a clear roadmap of the next steps the
cooperative will take. Finally, once the REC has successfully developed its first projects, it
should expand its activities into adjacent topics, such as electric mobility with the final aim to
become a regional renewable energy provider.
Interview 3 - REC Odenwald
Founded in 2009, the REC Odenwald belongs to the first generation of German RECs and is
one of Germany’s biggest renewable energy cooperatives in terms of invested capital and
members. The interview was conducted on the phone with the managing director and co-
founder of the cooperative.
The motivation for the founding of the REC Odenwald was twofold: first, citizens and
cooperative banks wanted to invest in renewable energies and second, roof owners wanted to
benefit from roof renting. Hence, the regional cooperative bank seized the opportunity and
founded a REC.
Moritz Hentschel, 441663 – Master Thesis
44
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
The founding process was guided by the local cooperative bank, which delegated employees to
prepare the necessary founding documents. Once these were ready, 12 founding members were
gathered, including the mayor of the biggest city in the region, and the founding documents
were signed. From the beginning, the bank delegated one employee to professionally manage
the cooperative’s activities.
The interviewee mentioned establishing trust between the cooperative and its stakeholders as
the main challenge that the REC Odenwald encountered. Furthermore, it was demanding to
convince other municipalities to join the REC instead of founding their own cooperative. This
was crucial, since the business model of the REC Odenwald relied on a centralized approach
that would gather many municipalities of the region under one umbrella organization.
The following characteristics define the REC Odenwald: first, compared to other RECs, the
REC Odenwald has a high percentage of companies among its members. This can be explained
by the fact that one of its founding members was a company (local cooperative bank), which
lead to the creation of an organizational structure that attracted other companies. Most
companies joined either for idealistic or for business development reasons (the REC prefers to
hire local companies for its projects which incites local companies to become a member).
Second, the REC cultivates a close and good relationship with the local administration, which
enabled it to gather many municipalities within its organization and to follow a centralized
approach. Third, this strong regional presence and good public relations, as well as the fact that
local companies are preferably hired for the execution of projects, has led to an equally good
relationship with the local community. Fourth, 5% of its members are roof owners and there
are no external investors involved.
Regarding potential characteristics of a cooperative at the Port, the interviewee could
recommend the following: it would be crucial to explain each stakeholder his benefits in detail
and full transparency to gain the trust of the Port community. Furthermore, the one man one
vote regulation might not be the right approach in a situation where only companies are
members of the cooperative. Finally, it would be important to sign long term power purchase
agreements and roof renting contracts with the members of the REC to generate the necessary
security for all parties that are financially involved with the cooperative.

Interview 4 - REC Köln
Founded in 2010, the REC Köln is now a highly professionalized energy cooperative. At the
time of the interview, the cooperative was expanding as it was hiring additional full time project
managers for future projects. The interview was conducted on the phone with one of the co-
founders who also works as managing director of the REC.
The motivation of the founders was twofold: first, they saw that with a cooperative it would be
possible to achieve societal change regarding our energy supply. Second, they believed that a
cooperative could be an interesting mean to achieve such a societal change through the power
of economic incentives. Hence, their motivation was a mix of ideological and financial
considerations. This was enhanced through the fact that cooperatives offer the opportunity to
apply a democratic decision making mechanism without having to forgo the benefits of a
financially motivated organization.
The founding process was initiated by two co-founders. They prepared the necessary documents
and then invited six friends, who they believed would have specific competences that the
cooperative might need later. During the preparatory period, the other founding members were
kept informed about the process, but they were not actively involved in the work. Thanks to
diligent preparation, the founding gathering happened without incident and all members quickly
signed up. The cooperative had a concrete first project in mind. Unfortunately, this project
failed and it was only after the second project eventually succeeded that the REC Köln started
growing in members.
The interviewee mentioned three big challenges the cooperative had to tackle: the biggest
challenge was achieving professionalization. Professionalization was from the beginning the
goal of the founders, but it was only after the first big project was completed that they could
start paying salaries out of the cash flow of this project. The second challenge was and still is
the project development itself, since developing solar energy projects is time consuming and
always related to a lot of uncertainty. Finally, the cooperative had to cope with the constant
regulatory changes of German renewable energy regulations.
The characteristics of the REC Köln can be described as follows: first, the cooperative
originally gained new members from the regions where it installed solar energy systems; new
members liked the local character of the investment they would make. Second, companies are
Moritz Hentschel, 441663 – Master Thesis
46
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
members, but mainly because their CEO was convinced by the idea of the cooperative. Main
motivations for companies are marketing and ideological aspects. Third, the cooperative has a
strong safety mechanism for its members, by not involving any debt into the financing of the
cooperative itself. This is achieved by a separation of the cooperative and the projects it
develops. Hence, by becoming a member of the REC Köln, one gains the option to invest in the
projects developed by the cooperative. There is, however, no obligation and the financial
performance of the cooperative is decoupled from different projects. This construct leads to an
important fourth characteristic, which is a centralized structure organizing decentralized
projects. This means that there is one project development bureau within the cooperative that
develops projects in different regions in which only parts of the members invest each time (often
with a local character). This lean structure saves cost and leads to the above-mentioned safety
benefits for all parties involved. Fifth, no roof owners are members of the REC. According to
the interviewee, roof owners normally only have one interest, which is renting out the roofs, no
strings attached. Sixth, the REC Köln initially only used funds from members as its own capital.
But throughout time it developed mechanisms for external investors (no banks) to contribute
subordinated debt to projects. This helped the cooperative to realize projects for which there
would not have been sufficient funds from members.
Finally, the interviewee mentioned the following potential characteristics as beneficial for a
cooperative at the Port: first, it should be managed professionally from the beginning. Second,
its scope should be local and explicitly focused on the Port area. Third, its organizational design
should allow for easy integration of latecomers, since many companies will only join once they
see success. Fourth, the typical one man one vote rule should not be applied to its fullest extent.
In fact, in Germany it is allowed to soften this rule. Accordingly, bigger members should in
some way receive more weight in the voting mechanism. Fifth, the cooperative should not only
focus on solar energy and roof top projects, but it should also enter adjacent areas in order to
allow its members to prosume. This could be achieved by developing power heat coupling or
organizing bundled renewable energy purchasing.
Interview 5 - REC Heilbronn-Franken
The REC Heilbronn-Franken is a well-established REC that was founded in 2010 and develops
projects in Southern Germany. The interview was conducted in its offices with one of the co-
founders who now works as managing director and project developer.
Moritz Hentschel, 441663 – Master Thesis
47
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
As motivation for the founding of the cooperative, the interviewee mentioned achieving the
energy transition through a scalable business model.
The founding process was initiated by 10 founding members who had a specific first rooftop
project in mind, which they would not have been able to finance on their own. After some
research, they decided to apply the cooperative model, since this organizational forms allows
its members to easily realize many projects together. To gain some first insights on setting up
a cooperative, the founding group sought consultation from an umbrella organization, which
provided them with bylaws and other useful documents. After having gathered this information,
they organized a founding event with 46 members, who all signed up for a membership that
same day. The motivation of the founding members was a combination of protection of the
environment and financial return. After the founding event, the circle of active members quickly
decreased.
According to the interviewee, the biggest challenges the REC faced were the following: first,
the REC had to constantly adopt to the regulatory changes. Second, the cooperative had to
quickly achieve professionalization, which meant that it had to generate cash flows that would
pay a full-time salary for a managing director. Apart from that, a third challenge remained to
motivate competent volunteers to support the management.
The following characteristics define the REC Heilbronn-Franken: first, the cooperative is
professionally managed by a managing director. This enables it, second, to achieve scalability
and to develop large scale solar projects. Third, companies are members of the cooperative.
Their motives are business development, long term investments and for one company its CSR
policy. Fourth, the REC fosters a strong ecological image. Fifth, it enables its members to
receive a financial benefit from their membership (many RECs are in fact non-profit
organizations). Sixth, there are no roof owners among the members of the cooperative, since
according to the interviewee, roof- owners prefer to keep contractual relations with the REC at
a minimum and are only interested in the roof rent. Finally, the REC does not receive external
funding and finances its projects exclusively with the money of its members.
To conclude, the interviewee suggested the following potential characteristics for a REC at the
Port: first, the cooperative should understand very well that it would have to deal with a variety
of stakeholders that have diverging interests (roof owners, energy consumers, Port authorities
Moritz Hentschel, 441663 – Master Thesis
48
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
etc.). Second, since many companies will not be willing to invest in projects, (the cash flows of
solar energy projects are not attractive enough compared to their core business), an external
investor might be required to contribute at least parts of the required own capital. Third, a REC
at the Port would have to engage in prosuming activities since, if there is no pairing of
consumption and production, the roof renting could be done by a fund or something similar. In
this case, there would be no need for a REC. Finally, once the first roof-renting projects are
successfully completed, the cooperative should offer additional services in adjacent areas, such
as energy management or bundled electricity purchase.
Interview 6 - REC Heidelberg (second co-founder)
In the spirit of the progressive case study method, it was decided to close the first case
interviewing the REC Heidelberg for a second time as one way to achieve cycling between data
collection and data analysis. One of the benefits of this approach was that it allowed the
researcher to apply the enhanced interview that had evolved throughout the first case study to
the REC Heidelberg. Thereby, it could be ensured that all relevant questions which developed
throughout the research would be asked to the REC Heidelberg, which was considered
important enough to be the starting point of this research. The interview was conducted again
at the offices of the REC Heidelberg. This time, however, a different co-founder of the
cooperative was interviewed. In the following, only content that is of additional value to the
first interview will be displayed.
The motivation leading to the founding of the REC Heidelberg was of ideological nature, in the
sense that it aimed at achieving the energy transition through a scalable business model. This
scalability, however, should be achieved in collaboration with citizens.
The founding process was initiated by four students who had a specific first project in mind,
which they wanted to realize.
The biggest challenges that the REC encountered were: first, achieving economic viability.
Since the REC Heidelberg wanted to be professionally organized to achieve scalability, it had
to be able to finance the salary of its managing directors. Second, due to the regularly changing,
complex renewable energy regulations, the cooperative had to constantly evolve its business
model.
Moritz Hentschel, 441663 – Master Thesis
49
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
Accordingly, the characteristics that define the REC Heidelberg are: first, professionalism and
economic viability. In contrast to most other German RECs, the REC Heidelberg can finance a
salary for its managing directors through its own cash flows. Second, due to the need to adapt
to new regulations, the cooperative has developed a good understanding of energy trading,
which enables it to sell energy to tenants of social houses. Third, the cooperative has no external
investors and procures the capital for its projects exclusively from its members via subordinated
debt.
The interviewee recommended to develop the following potential characteristics for an REC
at the Port of Rotterdam: first, roof owners should be among the founding members. Second,
the cooperative should develop a simple smart grid with smart meters among its members to
enable the cooperative to expand into adjacent business activities, such as energy trading and
combined storage. Third, employees of the companies that are members of the REC should be
allowed to invest in the projects developed by the cooperative. This would spur a more profound
energy transition at the Port, since by investing the people working at the harbor would become
more aware of the need of building a sustainable energy system.
Conclusion
Case 1 served as starting point for this research by gathering general information on RECs in
Germany, one of the leading countries in the field of energy cooperatives. This sensitized the
researcher for crucial concepts related to the research question and directed the data collection
in promising directions (Steenhuis and De Bruijn, 2006). In the following, case 2 will be
presented.
5.1.2 Case 2
Case 2 contains the data collected on Dutch RECs. In the spirit of the progressive case study
method, this case will enable the researcher to refine the data gathered in case 1 by collecting
data within the environment of the research object, the Port of Rotterdam. Similar to case 1, the
results will be presented in accordance with the research framework presented in Chapter 3
(motivation and goals, history and processes, challenges and recommendations).

Interview 7 - REC Amsterdam South (Zuiderlicht)
Founded in 2013, the REC Zuiderlicht is now one of the most active renewable energy
cooperatives in Amsterdam. The interview was conducted after a conference of RECs in
Amsterdam with the managing director and co-founder of the cooperative. Zuiderlicht was
chosen as starting point for the second case of this thesis, because this cooperative is well
connected within the Dutch cooperative environment and the managing director has developed
an extensive knowledge about cooperative business models that involve companies as
members.
The motivation of Zuiderlicht’s founders was of idealistic nature. They wanted to engage in
creating a more sustainable energy system for the region of Amsterdam. Furthermore, they saw
that there was a clear business case and that cooperatives receive favorable treatment with
regards to attracting senior debt. Their goal was to create a societal movement, following their
conviction that the energy transition must happen through a bottom up approach that
fundamentally changes the way people perceive energy. Finally, they are fully convinced that
prosuming is the right approach to the energy transition, since it keeps the profits generated
through energy procurement and sales in the hands of the local communities, which will lead
to additional investments in renewable energies and thereby initiate a virtuous cycle.
The founding process was initiated by five people with a specific roof that they wanted to equip
with solar panels. Due to their limited knowledge, they contacted RESCOOP (see Chapter 2),
who provided them with the necessary support material and guidance. Eventually Zuiderlicht
ended up adopting the bylaws of one of RESCOOP’s Belgian members. Finally, the five
founding members signed the bylaws and realized their first project, after which other members
quickly joined the cooperative.
The main challenges the cooperative faced were: first, finding the right business model, since
the Dutch regulations on renewable energies and cooperatives are not easy to apply. Second,
developing the projects and running the cooperative, which is highly time consuming. Initially
this was a big issue, since all members worked on a voluntary basis. Therefore, the third
challenge was professionalizing the REC, which was only possible after a certain threshold of
projects were completed and sufficient cash flow was being generated.
Moritz Hentschel, 441663 – Master Thesis
51
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
Zuiderlicht’s characteristics were defined by the interviewee as follows: first, the REC asks its
members to pay a low membership fee of 1 € to have access to all the services Zuiderlicht
provides. This characteristic developed out of an initial challenge of the cooperative. In the
beginning, the founders of the REC planned to ask external investors to fund the projects of the
cooperative. However, due to Dutch regulations, this is difficult to organize. Therefore, they
decided to ask for a 1 € membership fee from each investor, which had two important benefits:
first, there would be a constant increase in members due to low entrance barriers and second,
once an investor would be member of the cooperative it would be more probable that he
continuously engaged in other activities of the REC. The second characteristic mentioned by
the interviewee was that Zuiderlicht has companies among its members and that they often have
special roles, such as renting out their roofs to the cooperative or purchasing electricity
produced by the REC. Third, Zuiderlicht tries to keep the fun-factor of the energy transition
alive. The cooperative is convinced that making the energy system more sustainable is an
exciting mission and tries to sustain this ambiance among its members, by making their
membership experience as pleasant and stress-free as possible. Finally, Zuiderlicht is only
financed by capital of its own members and solely borrows senior debt for the individual
projects.
To conclude, the interviewee recommended two potential characteristics to the design of a
REC at the Port of Rotterdam: first, it should apply a combination of the SDE+ subsidy and the
post-code regulation. Thereby it could receive subsidies from the Dutch state for each kWh
produced (SDE+) and at the same time earn more per kWh by selling the electricity directly to
companies of the port instead of on the energy market (post-code regulation). Second, the
cooperative should be open not only to the companies at the Port, but also to the employees of
the companies at the Port. This would lead to a more profound engagement of the port
community and allow for a bottom up change of the system.
Interview 8 - Industry Journalist
This interview was conducted with a journalist who is specialized in researching the Dutch REC
sector. By consulting various organizations that are active in the field of disruptive innovations
and by writing about the evolution of RECs in the Netherlands, this journalist has gained a good
understanding of how renewable energy cooperatives work and what challenges they face. The
interview was conducted during a conference on RECs in Amsterdam.
Moritz Hentschel, 441663 – Master Thesis
52
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
According to the interviewee, many RECs’ main motivation is to drive societal change
regarding the energy transition. Thereby, they have become a successful mobilizer within the
Dutch society when it comes to aiming for a more sustainable and democratic energy system.
Further, RECs are a brilliant place for social experiments, (i.e. a load capacity test that was
organized by the REC Lochem, see below), but also to receive financial support from the state
that can lead to powerful success stories. Consequently, RECs can be seen as energy transition
accelerators, which make sure that the transition happens rather sooner than later.
In the eyes of the interviewee, a perfect REC should contain at least the following
characteristics: first it should have a professional management core, whereas much of the work
can still be assumed by volunteers. Second, the cooperative should design a clear
communication strategy, since it is crucial from the beginning to explain well to all stakeholders
what the cooperative is about and why each stakeholder can benefit from it. Therefore, the REC
should know and understand its stakeholder very well to be able to communicate its goals in
the right way.
Regarding potential characteristics, a cooperative at the Port should develop, the interviewee
named the following: first, it should be checked what companies, start-ups or organizations are
already active in the field. Often there are many interesting initiatives but the breakthrough is
not achieved due to a lack of communication and collaboration among the different initiatives.
Second, the cooperative should define a clear goal, which is simple, easy to understand and not
too unrealistic to be achieved. This goal has then to be well communicated to first movers
together with a consistent road map of how to achieve the goal. Third, the REC should intend
to design its structure in such a way, that it “works with the community and not for the
community”. For this, low entrance barriers for future members are required. Fourth, it should
be considered to brand the REC not as cooperative but as a smart city initiative, since
cooperatives often do not have an appeal of modernity and success. In fact, this would suit
Rotterdam’s recent modernization efforts. Finally, it would be very important for the
cooperative to quickly achieve first results, which it should then display well to motivate second
movers. This could be done through an app that shows how many roofs are already equipped
with solar panels.

Interview 9 - REC Lochem
The REC Lochem was founded in 2010 and is one of the oldest and biggest Dutch prosuming
cooperatives owned by citizens. The interview was conducted with the founder and managing
director of the cooperative via phone.
The underlying motivation of the founding was to enable the people of Lochem to perform a
local energy transition. Hence, the cooperative was founded mainly for environmental and
political reasons, but also for economic reasons, since its business model allows its members to
have access to affordable solar energy for self-consumption.
The founding process was first initiated by the government and a local energy company.
However, since this initiative did not receive the endorsement of the population, the interviewee
was asked to organize a founding process led by the citizens of Lochem. Therefore, he gathered
36 volunteers and prepared the founding via six workshops. Eventually, the group decided to
opt for a cooperative, since its organizational model would provide sufficient safety regarding
the investment of each member. Another reason was that cooperatives are a good vehicle to
attract senior debt.
The interviewee mentioned two main challenges the cooperative has been encountering so far:
first, the project development is highly time consuming and every project might fail until the
very last moment of its development stage. Second, since the project development is so time
consuming, the cooperative had to hire project developers, which was not easy due to the REC’s
limited funds. Hence, professionalization was also a big challenge.
The following characteristics define the REC Lochem: first, due to the regulations at the time
of its founding, the REC initially developed a business model that allows its members to rent
solar panels from systems purchased and installed by the cooperative. Second, the cooperative
does not accept companies as members, since it wants to avoid power. According to the
interviewee, cooperatives that have both citizens and companies among its members cannot
function well, since there would always be a concentration of power among few companies.
Third, the REC Lochem is a pioneer in the Netherlands when it comes to technical and
organizational research regarding renewable energies. For instance, the cooperative once staged
a community overload by organizing an event where all members located in a certain area would
turn on all electrical devices to measure, how much load the local grid could handle. Fourth,
Moritz Hentschel, 441663 – Master Thesis
54
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
due to its research, the cooperative has good connections to universities and grid companies.
Fifth, there are no rooftop owners among the members of the cooperative, because the
regulations in the past did not allow to develop a business model that would have suited roof
top owners. However, this situation has now changed (see below). Sixth, the REC Lochem only
invests member funds as own capital.
According to the interviewee, the following potential characteristics could be beneficial for a
REC at the Port: first, the REC should apply new regulations, especially the post-code
regulation, which allows owners of photovoltaic power plants to directly sell the solar electricity
to consumers in the same or surrounding post code area. Interestingly, this regulation only
applies if the producer and the consumer of the electricity are linked through an organization,
preferably a cooperative! Second, the cooperative should also engage in adjacent business areas
such as power to gas. According to the interviewee, the Port of Rotterdam is an important
energy port that might suffer significantly form the decreasing gas production of the Groningen
gas fields. Hence, engaging in green gas, generated by local solar energy could be an interesting
alternative.
Interview 10 - REC Amsterdam North (NDSM)
The REC NDSM has been founded in the industrial area of what was once the biggest shipyard
in the world, the NDSM shipyard. Located in northern Amsterdam this area was long
underdeveloped, after the shipyard had to declare bankruptcy in the 1980s. In the last 10 years,
the area has witnessed a strong revivification and is now a vibrant, modern industrial zone that
houses among others, offices of HEMA B.V., the BAM Group as well as the European
headquarters of MTV. Within this community the REC NDSM was founded in 2012. The
interview took place at the former shipyard NDSM with the current manager of the cooperative.
The motivation of the founders of the REC NDSM was to develop renewable energy power
plants in their industrial zone through a cooperative. This had essentially two underlying goals:
first, to supply green energy to their businesses and second, to build up a strong connection with
the local community. In fact, according to the founders, energy is a highly apt mean to connect
the local companies to the people living in the area. Furthermore, since the cooperative was
established within an industrial zone that is located on an island, it benefited from a strong
feeling of common interests among its business community, which facilitated the foundation.
Moritz Hentschel, 441663 – Master Thesis
55
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
In addition, the cooperative has received the support of the Amsterdam municipality. Finally,
it must be noted that the general culture within the industrial zone clearly facilitated the
founding of the cooperative, since there is a good mix of creative and traditional, as well as
small and big companies on the island.
The founding process was initiated by four entrepreneurs who run companies in the NDSM
industrial zone. They prepared the documents and used their network to lobby for first member
companies before the official launch of the REC. Then, they prepared a launching event, where
they created an inspiring atmosphere, which lead many companies to sign up on the spot.
Another important strategic move was that they could present some first member companies
who had already signed up during that event. This way, they quickly attracted new members.
The biggest challenge that the REC is facing is the long duration of the development of its first
project. NDSM decided to develop wind turbines in the area as a first project. However, the
project development of wind energy power plants takes many years. Currently, the cooperative
is in its fourth year of existence, without having realized one project. The goal is to install the
windmills next year. Until then, however, the management will be busy explaining the long
duration of the project development to its members. Another challenge is a shortage of hands.
Even though the cooperative can pay one FTE, there is still a lot of work that has to be assumed
by volunteers, which are difficult to find and to manage.
The characteristics of the REC NDSM can be described as follows: first, the cooperative has
been professionally organized from the beginning. Second, to achieve this, it had to collect
financial funds through membership fees. These fees are categorized, so that smaller companies
have to pay less than bigger companies. Third, the cooperative painted a clear picture of its
goals from the beginning and made sure to communicate to the local businesses, that it would
create value for the community, which would in turn increase the value for each business.
Fourth, as mentioned above, the REC benefits from a particular location, due to the island
character of the industrial zone and the creative spirit that reigns there. Fifth, the cooperative is
fully supported by the local government. Sixth, the founders of the cooperative have been very
persistent and persuasive in the beginning, which has been helped by the fact that they are
members of the business community. Finally, the cooperative managed to establish the one
Moritz Hentschel, 441663 – Master Thesis
56
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
man one vote system, which has led to a feeling of familiarity and trust among the current
members.
The interviewee named the following potential characteristics as beneficial for a REC at the
Port of Rotterdam: first, the cooperative should to be managed professionally by at least one
FTE. Second, therefore it is important to find a way to gather initial funds to finance the launch.
This can be done through a membership fee, as in the case of NDSM. Third, to gather funds in
the beginning and to give the cooperative sufficient weight in the eyes of the Port community,
it is important to motivate some big companies at the Port to become founding members.
Fourth, the founders need to be highly motivated and convinced of the task, since the first steps
will not be easy. It would be of great help, if personnel from the Port authorities and the
municipality could be among these founders. Fifth, the cooperative would have to understand
the Port environment very well to know, to which companies to pitch the idea of a REC first.
Furthermore, a clear and easily understandable business plan must be prepared, which includes
financial calculations, since business communities are highly pragmatic. Sixth, before
organizing the launching event, 5-6 companies should already have signed up to the cooperative
(preferably 1-2 big ones). Finally, the REC should make an effort to explain the benefits that
the different stakeholders can achieve by joining and each member should have the option,
never the obligation, to invest in projects of the cooperative.
Conclusion
Case 2 marks the end of the first research phase (see Figure 5). Information has been gathered
on German and Dutch REC that will serve as data pool to identify common characteristics of
RECs. In the following, case 3 will introduce the second research phase.
5.1.3 Case 3
Case 3 contains the data gathered on companies located at the Port of Rotterdam and of other
relevant stakeholders. Different to case 1 and case 2, the results in this case will not be presented
in a completely uniform manner. This means that some interviews will be structured according
to slightly varying topics. The reason for this deviation from the first two cases is that case 3
has to cover a broader study population that is at the same time closer to the research topic than
the populations of case 1 and case 2. Therefore, case 3 must tackle a more varied panoply of
Moritz Hentschel, 441663 – Master Thesis
57
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
topics. This highlights the progressive nature of this thesis’ research strategy further, case 3
having a more specific data gathering aim than case 1 and 2.
Interview 11 - Kloosterboer BV
The company Kloosterboer BV is located at the Port of Rotterdam and specializes in
temperature controlled food products. In 2014, the company installed a 450 kWp solar system
for self-consumption on the roof of one of its warehouses and thereby became one of the first
companies at the Port to deploy solar energy on a large scale. Due to this leading role, the
company has been chosen as starting point for the third and last case of this study. The interview
was conducted at Kloosterboer’s headquarters with the project manager who was responsible
of developing the solar energy project in 2014.
According to the interviewee, the motivation for Kloosterboer to deploy renewable energies
was partly related to its internal sustainability mission, partly because of the increasing demand
for sustainable warehousing from its clients. Another reason was that the roof of the building
where the system was installed on, was highly suitable for photovoltaics. Additionally, since
Kloosterboer can consume all the energy produced by the system on site, the business case was
quite strong. Still, compared to the company’s standard payback targets, the solar energy
business case was not attractive. So, without the sustainability argument, the project would not
have been realized. Furthermore, the interviewee stated that electricity prices are generally
crucial for Kloosterboer’s competitiveness. In fact, energy cost is the second biggest cost factor
of the company. Therefore, the company buys electricity on the spot market. Resource
dependency, however, is not perceived as an issue. Finally, achieving a green image becomes
increasingly important for Kloosterboer, since the Dutch government and clients expect
sustainability measures. The Dutch government also gives incentives to investigate what can
be done to increase one’s degree of sustainability through initiatives like the lean and green
program. However, the problem remains that clients ask for more sustainability but are rarely
willing to pay higher prices to compensate for the necessary investments in green technology.
When asked about the discrepancy between available roof space and solar energy deployment
at the Port, the interviewee confirmed that solar energy is still in its infancy at the harbor. The
problem is that for companies the investment in solar energy is not attractive enough. Payback
periods currently range between 10-15 years, which is clearly too long for companies.

Furthermore, many warehouse roofs might not be suitable for solar panels, because they cannot
support the additional weight. Another problem might be that companies at the Port do not
expect the electricity price to increase significantly in the next decades. Given that the business
case of a solar energy project depends tremendously on energy prices, this decreases its
economic viability.
According to the interviewee, cooperation among companies at the Port is rare and only
happens if they can noticeably benefit from it. Examples of cooperation are Shell selling its
heat to greenhouses or shared bus services within the Port area. However, the Port area can
definitely be seen as an energy cluster and opportunities for cooperation are abundant. Hence a
REC could be a good idea.
When asked about whether he could imagine his company to enter roof or electricity
consumption pooling, the interviewee had a clear answer: if there is a business case for it, the
chances are high. The REC would have to offer conditions regarding the electricity price that
are at least equal to the current ones; the benefit then being that the energy would be clean and
self-produced. Furthermore, the cooperative would have to organize everything separately from
Kloosterboer, since if the company would have to put additional labor in the functioning of the
cooperative, this would generate costs. On the other hand, it must be made sure that the
cooperative does not touch on any confidential matters of its members.
Finally, the interviewee recommended the following characteristics for a REC at the Port: first,
it should present a strong business case offering better conditions to its members than if they
were on their own. This can be achieved through scale effects regarding for instance the material
purchase or the financing. A REC could also help with finding outside investors. In addition to
being strong, the business case would also have to be simple, since companies at the Port have
other core activities than energy procurement and trading and generally do not have too much
time to spend on deciding on such topics. Second, the REC could be initially financed by a
membership fee, but for Kloosterboer this should not be more than roughly 5.000 €. In any case,
the business case would have to include these costs and still be beneficial for the company.
Third, establishing a one man one vote rule would be tough, since companies are not used to
such decision-making mechanisms. Fourth, offering employees the possibility to become a
member could be a good idea, since it would increase awareness regarding energy costs among
Moritz Hentschel, 441663 – Master Thesis
59
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
the workforce, which would be beneficial for a company with high energy costs such as
Kloosterboer. Fifth, the REC would have to be an independent, professionally managed entity,
which does not require excessive management attention from its members.
Interview 12 - Port of Rotterdam Authority
The Rotterdam Port Authority is a company owned by the Municipality of Rotterdam (75%)
and the Dutch state (25%). Its aim is to manage the Port of Rotterdam and to provide a favorable
business environment to the companies located there. The company finances itself through
harbor fees and land leasing. The interview has been conducted at its headquarters with the
company’s corporate strategist.
According to the interviewee, the Port Authority is highly motivated to decarbonize the harbor.
In fact, the Port Authority wishes to develop the Port of Rotterdam into the forerunning example
of a well-functioning, sustainable port in a decarbonized world. Consequently, developing
renewable energies within the Port area is one of its main targets. On that matter, solar energy
is clearly still the “new kid on the block”. So far, the Authority has mainly acted as a facilitator
but is now starting to develop its own solar energy projects. The idea to develop a REC at the
Port has been presented by the Erasmus University of Rotterdam to the Port Authorities and
since then, both parties have been researching how to implement it. Up to now, they have not
been able to find a clear match between what such a cooperative could offer to the companies
at the Port and what the companies at the Port want. One of the explanations for this mismatch
could be, according to the interviewee, that the project’s scope has been too large. Maybe it
would be better to start the REC with some smaller pilot projects and then integrate these pilots
into one bigger system. The interviewee mentioned further, that energy costs are an important
issue for companies at the Port, which is why companies in the harbor area have developed an
impressive history of energy efficiency measures. Additionally, energy dependency can also
become an issue, especially for gas companies since the gas field in Groningen is depleting
faster than expected. To counter this issue, such companies have only two options: first, higher
efficiency and second, producing their own gas through technologies such as power to gas.
Consequently, the interviewee is convinced that the Port area is a favorable environment to
invest in renewable energy technology, self-produced energy being the next logical step for the
Port’s business community. In addition, the companies at the Port depend on the well-being of
the whole region, which is why they have a strong interest in adapting to the societal needs of
Moritz Hentschel, 441663 – Master Thesis
60
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
the local community (less pollution, more sustainability). Finally, the interviewee mentioned
that implementing a smart rather than a green image for the Port region would probably have a
higher impact, since it would show that the Port is an attractive region to invest in.
Regarding the discrepancy between available roof space and solar energy deployment at the
Port, the interviewee explained that solar energy companies could not yet present a business
case to the Port community that was strong enough. However, according to the interviewee,
due to the declining prices of solar energy, it is just a matter of time until such a business case
will materialize. The problem with the current subsidies is that they do not really suit the Port
environment. This applies especially to the Postcode regulation, since the Port harbors an
immense variety of different post codes. Another explanation for the discrepancy could be that
companies at the Port are used to large scale endeavors, whereas solar energy systems normally
constitute smaller, decentralized projects. A final explanation could be that many roofs at the
Port are not suitable for solar energy.
When asked about collaboration among companies at the Port, the interviewee stated that it is
common and often practiced. One example regarding energy would be large power-heat
cogeneration plants that have been built by joint ventures of businesses within the Port area.
Furthermore, cooperation is facilitated by the local industry organization Delta Links and the
Port Authority. Additionally, according to the interviewee, the Port can be called an energy
cluster, since there is a concentration of energy supply and demand. However, when compared
to other Dutch industrial zones, there are still a lot of energy efficiency synergies to be created
among companies. One example could be the Chemelot industrial zone, where it has been
possible to make use of the full potential its energy cluster provides by building a well-
functioning circular energy system.
Consequently, according to the interviewee, an alliance regarding solar energy at the Port of
Rotterdam should be a feasible idea. The business climate is ready and the community is highly
pragmatic. Hence, if a REC could provide a strong business case, there would be first movers
to enter it. Furthermore, the Port Authority would support such a REC, potentially financially,
if the REC could present a strong business case to the Authority. Such a business case would
have to stress that a REC at the harbor could bind the companies more to the community and
thereby increase the Port’s profitability. The interviewee further mentioned that establishing an
Moritz Hentschel, 441663 – Master Thesis
61
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
external legal entity, which organizes the cooperation among companies on energy matters
might be just the right facilitator.
Finally, the interviewee recommended that the REC should include the following
characteristics in its design: first, the REC should act as a match maker between compatible
parties, such as roof owners and energy consumers in the case of solar energy. Second, the
cooperative should only apply a one man one vote system if it has been agreed upon by the
founding members. Such a decision would have to be preceded by some negotiation among the
founding members. Third, offering employees cooperative membership is a good idea, since
this would foster a more sustainable bottom up approach to the energy transition at the Port.
Fourth, the REC should make energy flows at the Port visible and transparent to its members.
This could help them to better grasp the potential for collaboration. Finally, and most
importantly, the REC would have to present a clear and strong business case to all parties it
wants to convince of its endeavor.
Interview 13 - Rotterdam School of Management
The Rotterdam School of Management, a subsidiary of the Erasmus University, has always
been an active research partner of the energy industry, Shell being one of the school’s founding
partners. One of the recent developments in this context has been the foundation of the Erasmus
Center for Future Energy Business. The Center’s mission is to support the energy transition
through research. As discussed above, the Center is considering the option to establish an
energy cooperative at the Port of Rotterdam. The goal of this initiative is to establish a larger
research project that analyses the potential of collaboration on energy matters within industrial
clusters. This project could guide and support the energy cooperative at the Port of Rotterdam.
At the moment, the center is in discussion with companies and other stakeholders at the Port
about what scope such an energy cooperative should have and on which projects it should focus.
The interview has been conducted with the Center’s business director at the Erasmus University
campus.
According to the interviewee, the main motivation for companies at the Port to cooperate with
each other on energy matters is achieving synergies and thereby cutting costs. Another
motivating aspect that gains in importance is the rising pressure from the Dutch government to
increase sustainability. In fact, it could be decided relatively soon to shut down the coal power
Moritz Hentschel, 441663 – Master Thesis
62
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
plants at the Port, which would lead to a significant energy gap, in case no alternative energy
sources were being implemented.
The interviewee explained that the current research on the topic of collaboration at the Port
hints at a big challenge regarding trust. Companies at the Port are reluctant to let go of control
over important topics. Energy seems to be one of these topics. Since a cooperative would be an
organization that is external to the member companies, this might make companies reluctant to
sign up for it. However, the Port can clearly be called an energy cluster and it might be
interesting to analyze how other energy clusters organize collaboration.
The interviewee stated that the following characteristics would increase the likelihood of
success for a REC at the Port: first, when creating the cooperative, one must be careful of
leaving companies enough space within the organizational structure, in order to guarantee their
flexibility even after becoming a member. Second, financing the cooperative initially through
a membership fee could be a feasible idea, if the REC can present a convincing business case.
On that matter, it would be interesting to know, whether the Port Authority would also be
willing to contribute, since it has a strong interest in binding the companies at the Port. Third,
a one man one vote rule would probably not be a good idea, since companies would be involved
on different levels with different degrees of intensity. Fourth, integrating employees of Port
companies into the REC and giving them the opportunity to invest in projects of the cooperative
could be an interesting idea.
Interview 14 - Frigocare Rotterdam BV
Recently, the Port of Rotterdam earned a headline in the newsfeeds of the European solar energy
community, when it could announce the installation of Rotterdam’s largest photovoltaic power
plant on one of its cooled warehouses. In fact, in September 2016 Frigocare BV, a company
specialized in frozen foodstuff storage, commissioned a photovoltaic system of roughly 800
kWp on the roof of its cold storage facility. The interview was conducted at the headquarters
of Frigocare in the Port of Rotterdam with its managing director.
The interviewee explained the motivation behind this undertaking: in fact, the company did not
purchase the solar system. The project was realized in cooperation with the Dutch solar energy
company ZON XP, who financed and installed the system and sells the energy directly to
Frigocare. Frigocare’s only commitment is to purchase the entire electricity produced by the
Moritz Hentschel, 441663 – Master Thesis
63
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
system for the same price that it purchases the remaining electricity it obtains from its
conventional energy provider. According to the interviewee, this project has been a “no-
brainer” for the company, since it brings three major advantages: first, by eliminating grid costs
and taxes the self-consumed solar energy is 45% cheaper than the conventional electricity.
Second, the solar system acts as insulation, which due to the decreased direct solar irradiation
on its roof, will save the company 2-3% of its electricity consumption. Third, the company
increases its sustainability efforts significantly without any financial risk. Consequently, this
business model is highly attractive for Frigocare, since energy costs are an important cost factor
and as a subsidiary of Samskip it constantly tries to reduce its carbon footprint. According to
the interviewee, a green image is important for Frigocare, because it trades in fish, which is a
highly scrutinized commodity with regards to environmental impact. Therefore, the director
estimates that a green image is more important for the company than an innovative image, even
though both aspects play an important role.
Confronted with the discrepancy between available roof space and solar energy deployment at
the Port, the interviewee gave the following feedback: first, it is indeed striking that the,
relatively small, solar system installed on the roof of Frigocare increases the solar energy supply
at the Port by 40%. Second, the reason for this lack of solar energy deployment can be explained
by the long payback period of photovoltaic power plants. 10-15 years are too much for
companies at the Port who normally operate with much shorter payback periods.
The interviewee further commented that cooperation among companies at the Port is not
normal. Cooperation usually only happens among neighbors, where issues and synergy
opportunities are clearly visible and transaction costs are low. Another aspect that hindered
cooperation in the past is that managers have become careful of being accused of cartel building.
In fact, sharing basic information with other companies can quickly be interpreted as cartel
building, which can lead (and has led) to large penalties. This is why, according to the
interviewee, it is helpful to collaborate with an external entity, such as ZON XP, that takes care
of organizing cooperation. In fact, now that ZON XP has finished its first project at the Port, it
is expected that the company will contact other companies within the Port to apply the same
business model. The interest is rising. Concluding, the interviewee commented that cooperation
regarding energy in the form of heat has failed in the past and that he could only imagine a
cooperation in the electricity sector, similar to what ZON XP is doing. The main challenge
Moritz Hentschel, 441663 – Master Thesis
64
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
would be to find electricity consumers who would be willing to sign long term power purchase
agreements with the entity that organizes the cooperation (i.e. the cooperative).
According to the interviewee, the following characteristics would increase the likelihood for a
REC at the Port to succeed: first, it must be acknowledged that companies at the Port do not
like to give up flexibility and that there is not a lot of trust and familiarity among the business
community. Hence, the REC would have to be designed in a way that does not compromise the
flexibility of its members. Second, it would be imaginable to pay a membership fee, but only if
this was supported by a strong business case. The companies at the Port are highly pragmatic
when it comes to such matters. Third, the first companies to be addressed should have some
interest in energy issues. Fourth, a one man one vote rule would be a bad idea. The problem is
that such democratic decision mechanisms only function within a community that has other
goals than financial profitability. Fifth, allowing employees access to the cooperative would be
a very good idea. Sixth, most importantly the REC would have to present a strong and clear
business case on why it would be beneficial to become a member. Seventh, the Port Authorities
should be a member of the cooperative and support the initiative to its fullest extent. In fact, for
the solar project at Frigocare, the Authorities have been of great help, so there might be an
interest in supporting the REC as well. Finally, the first companies to be addressed as founding
members should have a visionary leadership. Unfortunately, this is not common among logistics
companies whose management teams generally practice a down-to-earth and highly pragmatic
business culture.
Interview 15 – Investment Fund
To get a comprehensive overview of the issue analyzed in this thesis, the researcher deemed it
necessary to also interview a stakeholder that has an investment view point on renewable energy
projects in the Netherlands. Therefore, an investment fund has been approached to provide
some insights on the topic. For confidentiality reasons the name of the fund cannot be
mentioned in this thesis. The interview was conducted at the headquarters of the investment
fund.
To start with, the interviewee explained that the fund invests equity and subordinated debt in
renewable energy projects in Europe. Therefore, the fund teams up with project developers to
realize projects by providing equity during the development phase. When asked about the
Moritz Hentschel, 441663 – Master Thesis
65
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
motivation of companies to invest in renewable energies, the interviewee commented that many
businesses have an interest in the clean and green aspect of the electricity generated. In fact, the
topic of green energy receives growing interest in the Netherlands. Another important
motivating element is to generate electricity independently and in a decentralized manner,
which has both financial and psychological benefits.
Regarding the discrepancy between available roof space and solar energy deployment at the
Port, the interviewee had two comments: first, this discrepancy is an interesting opportunity,
which the fund could potentially look at. The fund’s mission is to make things possible that
have not been possible so far. Second, to give a more detailed answer, it would be necessary to
look at the specifics of the different roofs. In fact, all smaller roof-top projects would have to
be bundled in one project, which would have to be well prepared and presented in a
homogeneous manner.
The interviewee further stated that there are potentially three main challenges related to project
financing that would have to be overcome at the Port: first, due to the size that a consolidated
project would reach at the Port, many developers would quickly run out of financial funds to
develop and eventually realize the entire project. Second, since the security for the senior debt
would be the projects to be built, the condition of the buildings on which the projects would be
installed, would play a crucial role. Such buildings would have to have an economic life of at
least 15 additional years. Also, maintenance of the buildings would have to be ensured for this
duration. Finally, if a power purchase agreement would be part of the business model, the
bankability of the parties to this agreement would have to be given for the entire duration of the
contract. Third, since many commercial buildings have been financed by other banks, it would
be necessary to find an agreement with these banks with regards to the ownership of the solar
systems. This means that these banks would have to accept that the solar systems could not be
used as collateral in case of an insolvency of a building owner.
Finally, the interviewee suggested that an important characteristic of an REC at the Port should
be the ability to aggregate many small projects into bigger homogenous projects. This would
make financing the projects significantly easier and increase the probability of large scale solar
energy deployment at the Port. Normally, such tasks are assumed by project developers.

Interview 16 – Rotterdam School of Management
In the first interview with the Rotterdam School of Management, the researcher was pointed to
a PhD candidate, whose research also touches on how to launch an energy cooperative at the
Port of Rotterdam. To exchange ideas, an interview was conducted with this PhD candidate at
the Erasmus University.
The interviewee noted that at the current state of his research, establishing an energy
cooperative at the Port seems to amount to a challenging undertaking. While the potential of
creating synergies is significant, it is hard to find common ground between stakeholders who
have very different interests and concerns. Generally, an energy cooperative at the Port should
act as an entity that “aggregates resources, which would be too small to be usable on a small
scale”. When asked about the motivations of companies at the Port to join an energy cooperative
and to increase renewable energy deployment, the interviewee stated two elements: first,
companies see a marketing benefit in using renewable energies and in presenting themselves as
companies that act within a collaborative environment. Second, companies are interested in
lowering their costs through decentralized and renewable energy procurement. Additionally,
the interviewee claimed that energy dependency is not an issue, which companies at the Port
deem important, costs being the main factor they are concerned about.
Confronted with the discrepancy between available roof space and solar energy deployment at
the Port, the interviewee answered that his assumption was that due to Dutch weather
conditions, wind energy is more cost effective than solar energy, which is why at the Port one
can witness the deployment of wind turbines instead of solar energy power plants.
When asked about cooperation at the Port, the interviewee answered that in his opinion
cooperation among direct neighbors is common. For instance, one company might have a
pressurized air outlet for which it does not have any use and, therefore, allow its neighbor access
for a small fee in case of need. However, on a larger scale, cooperation does not seem to be
normal. The interviewee further explained that this phenomenon might be due to the fact that
companies do not see the benefit of collaborating with other companies which are located far
away.
According to the interviewee, the following characteristics would make a REC at the Port
successful: first, its initial financing should be done by membership fees. While the interviewee
Moritz Hentschel, 441663 – Master Thesis
67
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
was not sure whether companies would easily accept this condition, he noted that this is the
way other RECs work, which leads to the assumption that it is an effective mechanism. Second,
the voting mechanism would have to be based on a smart solution. While big companies might
be reluctant to accept a one man one vote system, completely ignoring such an approach would
erode the concept of a cooperative. A smart solution could be to assign voting rights according
to a company’s energy consumption. Third, employees should be allowed access to the
cooperative as private citizens. Fourth, the REC should start with a focus on power purchase
bundling, but not limit itself to this activity, since it is in fact the “least intriguing” aspect of a
REC. The reason is that power purchase bundling is an activity that is already performed by
utilities, meaning that the REC would not contribute much added value. Consequently, other
activities should also be performed, such as crowd financing of energy generating and storage
projects as well as negotiating with the grid operator to establish pricing mechanisms that
stimulate grid friendly consumption patterns. Fifth, the REC would have to put effort in
establishing trust between the organization and its members. According to the interviewee,
many companies are reluctant to share information regarding energy. This issue must be
overcome. Companies “would not have to trust each other one bit, but they would have to have
absolute faith in the cooperative and that it handles their data with care”. The interviewee further
mentioned that RECs have shown to be highly efficient conflict resolution instruments, which
in the case of the Port would be an important feature to establish trust and manage stakeholders
with different interests. Sixth, a REC at the Port should start with a concrete project, since this
would help to motivate first movers and establish trust early on. Seventh, allowing external
investors access to projects developed by and for the REC could be a feasible idea However,
similarly to the voting mechanism, one would have to be careful not to erode the initial idea of
a cooperative. Another issue could be that allowing external investors access could lead to
greater conflicts of interest. Still, in the opinion of the interviewee, what should matter for the
Port and the REC is “where the project is located, not who finances it”.
Interview 17 – Hoogendijk Import Export BV
Hoogendijk’s activities as a fish trader date back to 1750, when the company still owned its
own ships. Nowadays, the company is specialized in trading with exotic sea food, operating a
large cold storage, which is why it is interested in deploying solar energy. The interview has
Moritz Hentschel, 441663 – Master Thesis
68
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
been conducted with the current managing director at the company’s headquarters in
Vlaardingen.
The interviewee started by stating that for his company, now would be a good moment to invest
in a solar system, since the roof of the company’s building will be renewed. The underlying
motivation to use solar energy for self-consumption is twofold: on one side, it will save costs
due to the elimination of grid fees and taxes. On the other side, it fits into the ideology of the
company. The interviewee stated further that the solar system his company will install will not
cover all its energy demand and that it would, therefore, be interesting to gather several
companies in the neighborhood that could produce a larger amount of solar energy together.
When asked how important a green image and an innovative image is for the company, the
interviewee replied that as a fish trader, achieving a more sustainable image through renewable
energies is significantly more important than engaging in innovative projects. If anything,
“really interesting” innovative projects could only be organized on a large scale, by a group of
companies.
The interviewee further argued that the discrepancy between available roof space and solar
energy deployment at the Port can be explained by three reasons: first, investment costs are too
high and payback periods are too long. Second, there are not sufficient economic energy storage
options. Third, companies normally do not see energy as a priority topic for their business.
When asked about cooperation, the interviewee gave a highly interesting answer. According to
him, cooperation in the business community of Vlaardingen has been growing significantly in
the last years. In fact, an association of 38 companies has been established, which is active in a
variety of fields. The first project it successfully launched was to hire one single garbage
collection company for all companies in the association. This drove down costs for garbage
collection by 40%! After this project was successfully implemented, more companies joined
the association and decided to broaden the scope of its cooperation. The next step will be to
invest together in surveillance cameras. A significant number of companies within the
association have even started pooling their energy consumption and appointing one person to
negotiate with energy providers, which has led to highly competitive energy prices. However,
the interviewee explained that cooperation is not something that is implemented easily.
Companies are not used to make money by collaborating with other companies. On the contrary,
Moritz Hentschel, 441663 – Master Thesis
69
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
it is competition that they are used to. Also in the case of the association in Vlaardingen, “people
first had to get used to the idea of cooperation”. It was, therefore, of big help that the first project
(garbage collection) was a success, because it proved companies that they could make money
together.
The interviewee stated that the following characteristics would help the cooperative to become
successful: first, engaging in roof pooling would be a good and feasible step, also in cooperation
with a company such as Zon XP, who has already financed and installed a solar system on the
roof of Frigocare, where Hoogendijk stores some of its products. Second, charging a
membership fee would only be possible, if companies understood well the risk they are taking
with it. This will not be an easy endeavor; however, it is also clear that one cannot expect to
launch such a project without prior investment. In fact, the cooperative should have more than
one professional manager. Two to three employees should take care of its functioning from the
beginning, since it would be too risky to put all the weight on the shoulder of one individual. It
would have to be highlighted as well that companies should pay a fee out of solidarity to their
community. The interviewee continued by mentioning that he is member of another association,
which employs professional staff and that in this association it is always made sure that there is
at least the sum of one year’s salaries in the bank account. Additionally, it would be helpful to
motivate a high number of members from the beginning, since this would distribute the
overhead costs among many parties and thereby lower the entrance barrier. The cooperative
would also have to present a strong business plan that allows it to finance itself after a short
while. Third, the voting mechanism would have to be realistic and should not be constituted of
a simple one man one vote rule. Nobody would accept that companies with little engagement
get the same voting rights as those who are heavily involved in the REC. Fourth, employees
should be allowed to invest in projects of the REC, since own capital will be needed. However,
the interviewee was not sure, whether they should also be granted membership. Fifth, the REC
would have to eliminate the fear of technical failure of the projects that would be financed by
its members. Sixth, especially in the beginning, the cooperative would have to show that it is
effective. Therefore, a concrete and simple starting project would be a good idea. Seventh, the
cooperative should be “big from the beginning”. According to the interviewee, the topic of
energy is important and needs attention. Therefore, it needs a strong cooperative, if possible led
by a big company located at the Port. Smaller companies normally do not like to take the risk
Moritz Hentschel, 441663 – Master Thesis
70
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
of being first movers. Eighth, external investors should have access to projects of the
cooperative, especially in the beginning when companies might still be reluctant to invest. The
interviewee added that energy is a commodity, which rarely touches upon the core business of
the companies at the port. Consequently, there is no need of being overly weary of cooperating
with other companies and external investors on that matter.
Interview 18 – Zon Explotatie Nederland BV
The closing interview for this research has been conducted with the founder and managing
director of Zon Explotatie Nederland BV (Zon XP). This company has caught the attention of
the researcher, when it was announced that it had developed, financed and installed Rotterdam’s
biggest solar system on the roof of Frigocare’s main warehouse at the Port, which was
commissioned in September 2016. Zon XP’s business model consists of renting the roofs of
buildings, installing a solar system on it and selling the solar electricity either to the roof owner
or to the grid operator at market price. Due to the SDE+ subsidy, the company is thereby able
to generate sufficient returns.
According to the interviewee, the motivation for companies to make use of Zon XP’s business
model is that they can save money on their energy bill and decrease their carbon footprint,
without having to invest themselves.
Regarding the discrepancy between available roof space and solar energy deployment at the
Port, the interviewee argued that there is a lack of entrepreneurship. The business model is
strong enough, so it is surprising that there are still so few systems installed.
The interviewee mentioned that establishing an external organization that takes care of energy
topics at the Port, i.e. a REC, would be a highly interesting idea. The characteristics of this
cooperative would have to be the following: first, it could be initially financed by a membership
fee. Zon XP would be willing to become a member through that mechanism if given the option.
Second, allowing external investors would probably be necessary to attract the necessary funds
to finance larger projects. However, when allowing external investors access to projects it must
be made sure that there are no ideological differences between them and the members of the
cooperative. Third, roof pooling of members of the REC would be a good starting project, since
Zon XP could then develop solar projects on the roofs and pay a yearly roof rent of
approximately 0.7 to 1 € per usable m² per year, for 15 years. Fourth, the interviewee mentioned

that potential founding companies would have to be well informed of the benefits a cooperative
would bring and that they should be “engaged by the founders”. Finally, the cooperative would
have to prove its effectiveness by successfully realizing a first project soon after its official
launch.
Conclusion
Case 3 constituted the final case of this research. Having presented the content of the interviews,
in the following the coded results will be outlined.
5.2 Results
As the research process design of this thesis shows (Figure 5), it has been the goal of this study
to identify common characteristics among existing RECs and to investigate whether these
characteristics would be helpful in the context of the Port of Rotterdam. In the following,
common characteristics that have been identified during research phase I will be presented and
explained first. In a second step, the results of research phase II, namely those characteristics
that can have a potentially beneficial impact on solar energy deployment at the Port, will be
outlined.
It is important to mention that the data presented here is not solely the result of direct questions
during the interviews. Certain insights have been coded from interviewees’ answers to
questions on other topics or from answers in combination with background material such as
bylaws or position papers. Finally, due to the semi-structured nature of the interviews,
interviewees had the opportunity to elaborate on topics that deemed important to them but that
provided data, which could not be directly used to extract characteristics. However, often these
insights were valuable for the goal of the research question. This led the researcher to gather
such information in a section called additional insights, which will be presented in a third step
and that will serve as supplemental data to answer the research question.
5.2.1 Research phase I
In research phase I, 10 interviews have been conducted with 8 different RECs and one journalist
who is specialized in RECs. In total, it was possible to extract 27 characteristics from the data
gathered throughout this phase. However, the goal of this this first step was to identify common
characteristics of the RECs interviewed. Accordingly, only those characteristics that have been

sufficiently verified through triangulation, which means that they have received a final score of
at least 3 (for grading mechanism please see below), will be considered as common. The
researcher knows that due to this threshold, valuable data might go missing. To avoid this issue,
an inclusive list of all characteristics mentioned throughout the first research phase can be found
in Appendix 4.
Common characteristics of RECs interviewed in Phase I
Table 2 presents 15 common characteristics that have been identified in research phase I,
meaning that they have received a score of 3 or higher. Each field marked with an “x” means
yes and has been awarded one point. Each field marked with a “-“ means no and has been
awarded with one negative point. Each time an “x” or “-“ is followed by a “o”, this means yes,
but or no, but and has been awarded with half a positive or negative point. The higher the
absolute value of a characteristic, the more it has been validated through triangulation. The list
of characteristics has been ranked accordingly.

Table 2 - Common characteristics of RECs interviewed in Phase I
Having presented the raw numerical data, in the following, each characteristic will be
elaborated on in more detail.
Professionalism is clearly the most common characteristic among the cooperatives interviewed.
While it is true that most RECs are run by private citizens on a voluntary basis, this study has
shown that those cooperatives that have companies as members (study population of this thesis)
are also predominantly professionally run. They have designed their business model in a way
that allows them to generate sufficient cash flow from the projects they own to pay at least one
FTE, mostly a managing director. This allows them to develop and finance more projects faster
and to achieve high visibility through professional marketing. One interviewee explained that
“if you really want to achieve an energy transition, it is important that your cooperative develops
a business model that is scalable and for this you need a professional management”. Other
interviewees pointed out that professionalization is also a real challenge for cooperatives and
that it is therefore important for RECs to state clearly from the beginning that they want to
generate sufficient funds to be able to pay salaries.
The second characteristic that could be deduced from the interviews is that successful launches
of RECs often involved a specific starting project. The underlying logic of this important
insight is as follows. First, the general public usually does not have a clear understanding of
energy procurement, let alone renewable energy power plants, their financing and installation.
Therefore, to find members willing to invest in the REC, it is crucial that the founders are able
to present a specific starting project that they can use as an example of how the cooperative
would operate. Second, having a specific starting project as reference point during the
foundation of the cooperative helps all parties involved to focus their time and energy in the
Moritz Hentschel, 441663 – Master Thesis
74
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
right areas and to make sure that results emerge of the endeavor. It has been recommended by
many interviewees to choose a starting project that is not too difficult to realize. For instance,
one Dutch cooperative started with the roof of a local tennis club and installed a mid-sized
photovoltaic power plant on it. Another important benefit of this approach is that once a first
concrete projected is implemented, it becomes significantly easier for a cooperative to attract
new members and financial funds, since it can prove that it is effective. This insight is supported
by the experience of the Dutch cooperative NDSM, who decided to choose a project consisting
of several wind turbines as starting point. Since developing wind parks takes years, the
cooperative, while making progress on the project every day, now has to spend a significant
portion of its time explaining to its members why there are still no visible results.
The third most important characteristic refers to the motivation of founding members. The
predominant answer to this question has been that the cooperatives have been founded to
achieve a mix of financial and societal goals. On one hand, due to good loan conditions for
cooperatives, financing renewable energy projects through a REC can lead to appealing returns
on invested capital for its members. On the other hand, cooperatives are a highly effective mean
to engage a community to achieve a certain goal (i.e. energy transition) and thereby to drive
societal change. The underlying logic of this second aspect is that people tend to take issues
more seriously, once they take ownership of it. Accordingly, by giving a community the
opportunity to invest in renewable energies and to benefit from generating its own electricity,
societal change happens because the community finally understands its responsibilities and
opportunities as an active member within a certain eco system. One interviewee explained that
this applies both to first movers as well as to late comers. Finally, it must be stated that among
the study population two cooperatives put greater emphasis on financial goals, whereas two
other RECs stressed more the societal goals. This shows that there are nuances with regards to
the importance of the two motivating aspects according to the general philosophy of a REC.
Consequently, a REC could be predominantly financially motivated, while still appreciating the
positive societal externalities it generates.
Seven of the eight RECs interviewed have been founded by 6 or less founders. Only one had a
significantly higher number of founders. This shows that successful foundations of RECs
should be organized by six or less private or juridical persons. Higher numbers of founders can
lead to nipping the endeavor of founding a cooperative in the bud, since too many stakeholders
Moritz Hentschel, 441663 – Master Thesis
75
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
want to contribute their opinion while no one feels responsible of guiding the energy in the right
direction. It is, however, important to distinguish between founders, which means people or
entities that organize the founding of the cooperative and founding members who are simply
the first persons to sign up once everything is prepared. In fact, with regards to founding
members, one interviewee stated that RECs composed of companies should not have too few
founding members. He argued that it is important to gather a critical mass of different
stakeholders (i.e. roof owners and energy consumers) in the beginning for the cooperative to
provide the kind of synergies it needs to build a strong business case.
Five out of eight RECs interviewed practice some form of prosuming, which makes it an
important common characteristic. This shows that one of the biggest benefit a REC can bring
to a community is the ability to give its members the ability to produce energy for and purchase
energy from the cooperative. One interviewee went as far as saying that if a REC at the Port
would not enable prosuming, there would be no point in founding it. His reason was that if it
gathered only roof-owners who would rent out their roof to the cooperative without consuming
any of its electricity, this task could also be assumed by a fund that simply rents the collective
roof-space and finances solar systems on it. Many Dutch interview partners also pointed out
that an important subsidy in the Netherlands called “post-code regulation”, actually pushes for
communities to practice prosuming.
Another common characteristic of the study population is that they tend to finance their projects
exclusively through own capital provided by their members and sometimes senior external debt.
This means that RECs tend to refuse to allow for investments concerning the own capital of the
project financing from external investors. This characteristic is also due to the fact that
regulations regarding cooperatives make it difficult to attract external funds from non-members.
Only one German REC designed a business model that allows external investors to co-finance
certain projects. Another cooperative mentioned, however, that given the short payback periods
of investments made by trading and manufacturing companies and the comparably high
payback periods for renewable power plants, a REC at the Port might not be able to attract
sufficient own capital from its members and might therefore be required to invite external
investors. The interviewee added that in the current situation (low interest rates on financial
products), it should not be difficult to find external investors to finance renewable energy
projects at the Port of Rotterdam.

Energy markets tend to be highly regulated. The same applies to current renewable energy
markets. Therefore, RECs often engage in political dialogue with policy makers. Accordingly,
half of the study population stated that they regularly engage with policymakers regarding
energy policy designs. This access to policy makers is somewhat surprising, given that most
RECs do not have a significant market share in their respective national electricity markets. The
reason is that RECs not only represent market actors in the energy industry, but also societal
movements with rich knowledge regarding energy consumers and producers that bigger market
actors sometimes lack, which is why they receive attention from politics.
Many RECs are managed by teams that work independently from the members of the
cooperative, which means that the REC de facto forms a legal entity that is separate from its
members. As a consequence of professionalization, this characteristic evolved within half of
the RECs and led to a centralized structure charged with developing new projects. Once these
projects are ready to be implemented and need to be financed, the members are included in the
process. One interviewee stressed this characteristic as highly important because it enables the
cooperative to “keep the fun-factor alive” for its members. Accordingly, there is a clear division
between members who finance the projects, rent out roofs or purchase energy and the
cooperative management that, as an independently functioning entity, takes care of all the
organizational work. This makes it possible to attract new members among people who are
convinced of the idea of an energy cooperative without wanting to be personally involved in
management activities.
Designing a clear organizational structure and a roadmap of steps to be taken after its creation
has been a crucial element for the success of many RECs. One interviewee stated that there are
two important elements to this characteristic. First, a clear organizational structure avoids
misunderstandings among members regarding their tasks, because even if there is a professional
management, voluntary work by members can remain an important component of success.
Second, presenting a clear organizational structure and a roadmap to new potential members
can increase their propensity to sign up because it shows that the business case of the REC is
well thought through.
Another characteristic that was named by half of the interviewees is the capability to remain
agile in the face of regularly changing regulations and market conditions. As mentioned above,
Moritz Hentschel, 441663 – Master Thesis
77
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
renewable energy markets are highly regulated, which means that changes in regulations have
a strong impact on its participants. According to the interviewees, it is therefore crucial for a
REC to develop the necessary dynamic capabilities and most importantly an innovative mindset
that enables it to react to such changes. Successful RECs are able to repeatedly find their niches
in new market conditions and to thereby continue to provide viable business models to their
members.
Four out of the eight cooperatives interviewed mentioned trust as one of the main challenges
they had to overcome. Especially in the beginning phase of a cooperative, new members have
to be convinced to join and then to invest in common projects. It is, therefore, crucial that
members trust in the effectiveness of the cooperative and in the fact that their invested capital
is well managed. Additionally, members also must build up trust towards other members, since
cooperatives are normally governed through democratic decision making mechanisms.
Consequently, addressing trust issues is an important characteristic that many of the
interviewed cooperatives have in common.
Closely connected to the characteristic of addressing trust issues, practicing democratic
decision making mechanisms has received an equal amount of points. In accordance with the
spirit of cooperatives, many RECs favor the one man one vote principle, where each member
has one vote, independent of his status, task or financial weight within the organization.
However, it has been mentioned by an interviewee that a cooperative, which is composed only
of companies, might not be suitable for such a voting mechanism. In fact, German and Dutch
regulations on cooperatives allow exceptions to this rule. It has to be mentioned, however, that
the NDSM cooperative, which is entirely composed of companies, has implemented a one man
one vote rule, which, according to its interviewee, has led to a “high level of trust and
familiarity” among its members.
Cooperatives often emerge out of a community that is concentrated in a certain geographic
region. For instance, the NDSM cooperative in Amsterdam emerged out of a business
community that is located on an island. Therefore, it is important for many RECs to cater local
needs to build up a good relationship with the community, which will facilitate their work and
attract new members. Also, many cooperatives have the intrinsic desire to connect with the
local community, because this fits their raison d’être. One interview stated that “in the eyes of
Moritz Hentschel, 441663 – Master Thesis
78
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
our cooperative there is no better way to connect with the people of our community than through
the topic of energy”. Therefore, a characteristic that has been mentioned by three cooperatives
is that their business activities are tailored to local needs.
As mentioned above, professionalization is the most common characteristic of the study
population. However, professionalization holds a significant challenge, which is generating the
necessary cash flow to finance salaries and other expenses. To achieve this, three of the
cooperatives interviewed charge a membership fee. This fee should be paid initially or on a
yearly basis by each member; one cooperative even differentiates between different types of
members (companies), which must pay different fees according to their size. According to the
interviewees, this characteristic brings another advantage next to the obvious benefit of
generating income for the cooperative. Charging a membership fee increases the feeling of
ownership among members, which often leads to a more sustained involvement and
participation. However, according to another interviewee, it must be made sure that such a fee
does not create too high entry barriers.
Finally, practicing intensive communication with stakeholders has been named as an important
characteristic by three RECs. According to the interviewees, stakeholders include the local
community, subsidy providers, local municipalities and (potential) members. Especially when
trying to convince new members to join, it is important to explain to them the benefits of
becoming a member. Also, during project development phases, which can take years depending
on the size of the projects, it is crucial to keep all parties informed about the current state of the
project to avoid dropouts, drying up of funds and loss of trust in the REC. This characteristic
aligns with the characteristic of establishing trust and of designing a clear organizational
structure and a roadmap.
Having presented the results of research phase II, in the following, the results of research phase
II will be outlined.
5.2.2 Research phase II
In Phase II, it was possible to extract 20 characteristics from the data gathered. Similar to Phase
I, characteristics had to pass a certain threshold regarding their triangulation grade to qualify.
A characteristic that passed this threshold could either confirm or reject existing characteristics
Moritz Hentschel, 441663 – Master Thesis
79
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
identified in Phase I, or constitute a potential (new) characteristic. Since in Phase II, 8 (instead
of 10) interviews have been conducted, the grading barrier was lowered from 3 (Phase I), to
2.5. The researcher is aware of the fact that due to this delineation, valuable data might be
discarded. To avoid this issue, an inclusive list of all characteristics mentioned throughout the
second research phase can be found in Appendix 5.

Table 3 - Confirmed existing, rejected existing and potential characteristics of RECs
In the following, only those characteristics that have not yet been identified in Phase I - i.e. the
potential characteristics - will be discussed to avoid repeating.
The port community constitutes a highly pragmatic business environment; this has been stated
and confirmed in several interviews. Since the primary goal of companies at the port is of
financial nature, decisions whether to invest in projects or whether to join a certain association
are taken based upon critical evaluation of the respective business case. Consequently, if a REC
at the Port wants to be successful, it must present a strong business case, this has been explicitly
stated by 7 out of 8 interviewees.
It is not only important that members of the REC have complete faith that the cooperative will
handle information with care and acts exclusively in the interests of its members. An additional
element of this characteristic should be that the REC concedes sufficient flexibility to its
members. Companies should not fear to lose part of their room for maneuver by joining the
cooperative. On the contrary, the cooperative should convey the certitude that companies can
gain access to opportunities they would have no access to on their own.
One of the RECs interviewed in Phase I suggested to allow employee membership within the
cooperative. In accordance with the progressive case study methodology, this idea has been
tested in Phase II and in fact, this characteristic has received a respectable score. Five out of
eight interviewees supported the idea that employees should have access to membership and to
investing in projects of the cooperative. Another interviewee also agreed that they should be
allowed to invest, whereas assigning membership and thereby voting rights would be a more
difficult undertaking. Generally, the reaction to this idea has been positive, since it would lead
to a real change in the mindset of employees regarding energy.
Half of the interviewees suggested that the cooperative should start with a large number of
participants. Two main arguments in favor of this characteristic have been brought forward.
Moritz Hentschel, 441663 – Master Thesis
81
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
First, dividing the overhead costs of the REC among many members would decrease the
membership fee. Second, energy is an important topic for the Port and a real impact can only
be achieved if large scale projects are implemented.
Acting as a matchmaker and make pooling of resources possible has been proposed as an
equally important potential characteristic. Accordingly, half of the interviewees see the REC as
an entity that organizes the bundling of resources to achieve scale effects and to enable its
members to have access to resources they lack. One example of such a match would be a
company with high energy consumption and no usable roof space for solar energy, which would
have access to the roofs of its neighbors through the REC.
Another characteristic that has been mentioned by three interviewees is efficiency. This refers
to the efficient functioning of the REC. The more efficient a REC functions, the higher the
benefits for its members and the easier it is to attract and retain members. This characteristic is
closely linked to professionalism, which implies efficiency.
The final characteristic is related to efficiency. Three interviewees stated that the REC should
partner with existing companies, such as project developers and utilities. Accordingly, by
outsourcing certain activities, such as project development or operations and management of
power plants, the REC could keep a lean structure, which would increase efficiency and keep
overhead costs as well as membership fees low.
Having presented the results that could be identified as characteristics, in the following insights
that might be of additional value for launching a REC at the Port will be discussed.
5.2.3 Additional insights
Throughout both research phases, interesting insights concerning the founding of a REC at the
Port have been gained that cannot be depicted as a characteristic. However, in the eyes of the
researcher, this information is valuable for the launch of the cooperative at the Port, since many
of them contain specific recommendations. Therefore, in the following, each insight will be
shortly addressed. Table 4 provides an overview of the insights gained, as well as an indication
on how relevant each insight is, based on the same grading system that has been applied to
identify the characteristics earlier. Comprehensive listings showing which interviewee gave or
supported which insight can be found in
Moritz Hentschel, 441663 – Master Thesis
82
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
Appendix 6 and Appendix 7.
Grades for insights gained in Phase II are higher since, due to the progressive case study
approach, in Phase I interviewees were offered more freedom to reply, which led to more varied
answers, whereas in Phase II more specific questions have been asked to confirm or reject
insights gained in the first phase.

Table 4 - Additional insights
Phase I
During research phase I, founders and managers of RECs with companies as members have
been interviewed. It can thus be argued with confidence, that the interviewees are experts when
it comes to founding and running industrial energy cooperatives. When asked how a REC at
the Port should be designed, many of them gave noteworthy recommendations.
Moritz Hentschel, 441663 – Master Thesis
83
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
First, the cooperative should be named in a way that allows many stakeholders at the Port to
identify themselves with it. Accordingly, choosing an inclusive name would increase the chance
to attract the amount and variety of members needed to have a real impact on the Port. Second,
one interviewee suggested that the REC should not be named cooperative but rather smart city
initiative. The interviewee argued that cooperatives have a reputation of being ineffective and
nonprofessional, whereas smart city initiative sounds attractive and might induce more
companies to join. Third, the cooperative should make sure to operate in such a way that its
members identify as part of a movement that improves the business location of the Port of
Rotterdam while upholding a certain fun-factor within the REC. According to the interviewee,
having the feeling to live an energy revolution inspires members of cooperatives to go the extra
mile and establishes trust. Fourth, one interviewee specifically recommended to integrate the
Port Authorities into the REC. This is why in Phase II, the Authorities have been interviewed
and asked whether they would join the project, which has been confirmed. Fifth, the cooperative
should put effort in signing long term contracts with its members regarding energy
consumption, roof renting etc., to provide sufficient safety for internal or external investors.
Two recommendations were given by two experts independently. First, the cooperative would
have to put a lot of effort in keeping the right balance between the interests of its members.
Since one of the characteristics of the REC should be to engage in prosuming, there will
certainly be stakeholders with diverging interests. For instance, members that mainly own roof-
space and do not consume a lot of energy would prefer the cooperative to pay high roof renting
fees, whereas members without suitable roof space but with a high energy consumption would
expect the REC to pay low rental fees to keep the electricity price as low as possible. The second
recommendation mentioned by two experts is that the REC should gather significant knowledge
on the energy consumption patterns of its members in order to find out where it can create
synergies.
Phase II
Six noticeable additional insights have been gained in research phase II. They will now be
elaborated on starting with the insight that has received the highest grade. First, six out of eight
interviewees consider establishing a REC at the Port to be a good idea, while the remaining
two interviewees abstained from confirming or denying such a claim. All companies
interviewed approved the idea. Second, companies and other stakeholders of the Port confirmed
Moritz Hentschel, 441663 – Master Thesis
84
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
that clients of the Port’s business community and the Dutch authorities increasingly demand
companies to take action on sustainability matters. This insight provides additional support for
the characteristic of having a mixed target composed of financial and ideological goals, since it
claims that both aspects will be increasingly intertwined in the future. Third, the business
community of the Port has been described as pragmatic by the interviewees. This insight is
connected to many characteristics, especially to the demand that the REC should present a
strong business case. All companies interviewed stated that, since they follow a pragmatic
business approach, they would be willing to engage in cooperative behavior if the underlying
business case showed that it would be worth investing time and money. The fourth insight is
related to the mediator of the research framework, namely the existence of an energy cluster at
the Port. Many interviewees confirmed that the Port can be called an energy cluster, no
interviewee denied this fact. However, it has also been stated that the potential of the cluster is
still not fully appreciated, which is why this assumption has only received an average grade of
3,5. Fifth, one interviewee recommended to search for companies as founding members that
have a visionary leadership. Since the cooperative would have to gather funds upfront to pre-
finance its overhead, it would be crucial that the founding members have faith in the success of
the REC. The sixth insight is related to the degree of cooperation among Port companies.
Regarding this topic, the answers of the interviewees have diverged, which results in a low
average grade. What most participants agreed upon was that cooperation could only be called
normal among direct neighbors. Consequently, it can be concluded that cooperation at the Port
on a large scale is not common, for now.
5.3 Chapter summary
In this chapter, the results of this thesis have been presented. Throughout both research phases,
a total of 47 characteristics could be identified. In phase I, 15 characteristics passed the
triangulation threshold that the researcher set up to build a high credibility level of the findings.
In phase II, 16 characteristics passed this threshold. This means that 15 common characteristics
of RECs have been identified in Phase I, whereas in Phase II some of them have been confirmed
to be beneficial in the context of the Port, next to several potential characteristics that were
identified. In a third step, this chapter provided an overview of additional insights that were
gained throughout both research phases. These insights could not be framed as characteristics,
Moritz Hentschel, 441663 – Master Thesis
85
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
but, according to the researcher, could be of value for the launching of a REC at the Port. Having
presented these results, it will now be possible to answer the research question of this thesis.
6 Concluding chapter
As has been mentioned at the beginning of this thesis, the underlying aim of this research is to
support the Erasmus Centre for Future Energy Business in its endeavor to establish an energy
cooperative at the Port.
Having conducted the research, three concrete contributions to this project can be provided:
first, the definition of characteristics this REC would have to contain to be successful. Second,
insights on the general circumstances in which the REC will be placed at the Port. Third, a
recommendation on how the cooperative should be launched.
In this concluding chapter, the first element will be addressed by answering the research
question. The two remaining contributions will be outlined in the Discussion chapter, as they
do not directly concern the research question.
6.1 Answer to the research question
The following research question was the starting point of this thesis:
Which existing or potential characteristics of renewable energy cooperatives would an
energy cooperative have to contain to increase the likelihood of solar energy deployment at
the Port of Rotterdam?
There are two types of characteristics that had to be deduced from the results presented in the
preceding chapter: existing and potential.
The research framework outlines the process that had to be followed to achieve this goal. First,
common characteristics had to be identified among existing RECs. The results of this research
step have been presented in subchapter 5.2.1.. Second, these characteristics had to be filtered
by interviewing stakeholders at the Port. Thereby, some characteristics were confirmed, some
were rejected, some did not receive sufficient attention. The results of this research step have
been presented in subchapter 5.2.2.. This lead to the identification of what is called in the
Moritz Hentschel, 441663 – Master Thesis
86
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
research question existing characteristics. Furthermore, stakeholders at the Port named potential
characteristics (5.2.3), that a REC should contain, which refer to the second part of the research
question.
In total 14 existing and potential characteristics of RECs that would increase the likelihood of
solar energy deployment at the Port of Rotterdam could be identified. They will be outlined in
the following.
6.1.1 Existing characteristics
Confirmed existing characteristics
Table 5 provides an overview over the existing characteristics of RECs that have been identified
in research phase I and confirmed in Phase II. The right column of the table depicts the summed
grade of the characteristic, which indicates its pertinence. The higher the grade, the more
pertinent the characteristic, 17 being the highest grade.

Table 5 – Confirmed existing characteristics of RECs
Research has shown that a REC at the Port of Rotterdam should contain at least 8 existing
characteristics of RECs. Since each characteristic has been explained in detail previously, they
will now only be put into context briefly.

Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
Most importantly, the cooperative’s mission should be composed of a mix of financial and
societal targets. The port community will identify itself with an organization that on the one
hand wants to achieve higher levels of sustainability within the Port and on the other hand aims
at helping its members to earn money. This will help the cooperative to attract members and
increase acceptance among stakeholders of the Port. Second, since the REC would be composed
mainly of companies, it would have to be managed professionally. Companies at the Port will
only be willing to invest time and money in an organization that presents itself as a highly
professional institution, since this conveys a feeling of efficiency, which in fact is one of the
potential characteristics that will be discussed later. Third, to convince companies to join the
cooperative, they first must understand its raison d’être. Consequently, the REC would have to
present a concrete starting project, which would help potential members to understand how the
cooperative would operate and what risks and benefits would be involved. This specific starting
project would have to be easy to understand and easily realizable. This would help the REC to
quickly establish trust. Fourth, a professionally managed REC has to finance salaries, an office
and other expenses. To be able to do this, it should charge a reasonable membership fee. Fifth,
the REC’s organizational design should make it a separate legal entity that functions
independently form its members. Thereby, companies could become a member without having
to worry too much about the cooperatives’ operations, while keeping full control over its
decisions. Sixth, research has shown that, currently, companies at the Port are careful to share
information and that they refrain from extensive collaboration. Consequently, the REC would
have to address this trust challenge actively, for instance, by presenting a specific starting
project that is easy to implement and thereby creates confidence. Seventh, for similar reasons
the cooperative must have a clear organizational structure and lay out a roadmap from the
beginning. Finally, the REC would have to engage in constant and intensive communication
with all stakeholders to explain the benefits of membership to potential members, create good
relationships with administrative bodies and the civil society of the Port area.
Rejected existing characteristics
Table 6 depicts those characteristics that have received a high positive grade in Phase I and a
high negative grade in Phase II, or vice versa. This means that these characteristics have a high
pertinence, but show conflicting results between both research phases. Consequently, these are
the characteristics that have been rejected.

Table 6 – Rejected existing characteristics of RECs
Even though the above shown characteristics have been rejected, they will be mentioned. The
reason is that due to their high pertinence in each research phase they must be considered when
recommending an action plan on how to launch the REC. First, the one man one vote rule has
been recommended by four out of nine respondents of Phase I and no interviewee advised
against establishing such a voting mechanism. Interviewees stated that even in a REC with only
companies as members, this rule should be upheld. However, respondents of the second
research phase rejected this rule with a clear grade of minus four. The second characteristic that
triggered opposing answers concerned the inclusion of external investors. Here, respondents of
the first phase clearly discarded the idea of allowing external investors access to the projects of
the cooperative. Hence, if confirmed, the characteristic would have been to keep external
investors out. However, interviewees of the second phase were more open to the idea. Since the
first phase led to a more pronounced negative grade than the positive grade of the second phase,
the final grade is still negative. Finally, it has to be noted that those characteristics, which did
not receive sufficient attention in Phase II are not mentioned here, since the results show that
they do not apply to the case of the Port of Rotterdam.

Table 7 provides an overview over the characteristics of RECs that have not been mentioned in
research phase I but which have been named repeatedly by the stakeholders interviewed in
Phase II, passing the threshold of 2.5. The right column of the table depicts the summed grade
of each characteristic, which indicates its pertinence. The higher the grade, the more pertinent
the characteristic, 8 being the highest grade.

Table 7 – Potential characteristics
Research has shown that a REC at the Port of Rotterdam should contain at least 6 potential
characteristics in addition to the 8 existing characteristics presented above. Since each
characteristic has been explained in detail previously, they will now only be addressed briefly.
By far the most important potential characteristic that has been named by the port community
is that the REC should present a strong business case. Seven out of eight interviewees indicated
that a REC would attract companies, if it could offer them a new opportunity to become more
profitable. All companies interviewed stated that they would join the REC given that its
business case is sufficiently compelling. Second, many interviewees confirmed that it would be
a good idea to allow employees of members access to the cooperative, which was a suggestion
of an interviewee of the first research phase. Third, the REC should start by acquiring a large
number of founding members. Fourth, the REC should act as matchmaker between companies
by pooling complementary resources. Fifth, the cooperative should convey an image of
efficiency and make sure to achieve results quickly and on a regular basis, to keep up the
motivation of its members. Finally, the REC should consider partnering with firms that already
have significant knowledge in the energy sector and, if possible, also with doing business at the
Port. Thereby the cooperative could focus on its core mission, which is enabling cooperation.
Conclusion
It can thus be concluded that 14 existing and potential characteristics have been identified by
the researcher. 8 of these characteristics belong to the category of existing characteristics and 6
of these characteristics have been identified as potential characteristics. Additionally, 2 of the
Moritz Hentschel, 441663 – Master Thesis

initially proposed existing characteristics have been rejected in the second research phase. In
the following this conclusion and complementary insights gained throughout this research will
be discussed.
7 Discussion
In this final chapter the two remaining contributions of this thesis to the launching of an energy
cooperative at the Port will be presented. Insights that have been gained but which are not
related to the research question will be outlined. First, those additional insights that shed light
on the literature summary model (Figure 2) will be discussed. Second, an action plan
recommendation for the launching will be provided. This recommendation will be based on the
results and conclusions presented in previous chapters and it will be the fifth and final research
step, as outlined in the research process design (Figure 5). After this, limitations of this research
and possible future research topics will be discussed. To conclude this thesis, practical and
theoretical implications will be presented.
7.1 Review of the literature summary model
The literature summary model of this thesis contains two assumptions, addressing the
underlying logic of the research question. First, it is assumed that a REC at the Port would
increase the likelihood of solar energy deployment (Figure 6). Second, it is assumed that an
energy cluster at the Port would have a moderating effect on assumption one (Figure 7). Based
on certain results of the additional insights section the following can be concluded concerning
both assumptions.
7.1.1 Assumption 1
Figure 6 - Assumption 1

There are two additional insights gained in research phase II that provide information regarding
this assumption. Table 8 depicts these insights and shows how each grade has been composed.

Table 8 – Additional insights concerning assumption 1
The results show that establishing a REC at the Port has been deemed a good idea by six out of
the eight interviewees, while none of the respondents argued against the launching of a
renewable energy cooperative at the harbor. Such a high grade reveals that the Port community
appears to be open to the idea of collaborating on energy matters through a cooperative. This
statement can be explained by the second result depicted in Table 8, namely that the Port
constitutes a highly pragmatic business environment. Five out of eight respondents indicated
that companies at the harbor tend to engage in business endeavors given that the underlying
business case is strong enough, even if this means exploring new territory. Again, none of the
interviewees gave answers that indicated the contrary.
It can thus be concluded that there is evidence confirming the first assumption of the model.
Many stakeholders at the Port, including all companies interviewed and the Port Authorities are
open to the idea of collaborating on energy matters. Additionally, the business environment at
the Port has been described as pragmatic. Consequently, if a REC could provide a strong
business case for Port companies, the first assumption would hold true.

Table 9 – Additional insights concerning assumption 2
When confronted with the literature on energy clusters and the fact that the Port of Rotterdam
has been used as an example to describe energy clusters, three respondents confirmed without
limitations that the Port can be called an energy cluster. One respondent agreed partly, while
adding that the full potential of the cluster lies untapped and that, therefore, the Port should not
yet be called a real energy cluster. None of the respondents denied the existence of an energy
cluster. Consequently, the results show that there is evidence indicating that the Port has at least
significant potential to function as an energy cluster. However, the results show also that
respondents were hesitant when confronted with that matter. One reason for this reluctance can
be found in the second finding depicted in Table 9. When asked whether they deemed
cooperation among companies at the Port to be normal, respondents gave mixed answers. In
fact, the grade of this insight is zero, since answers canceled each other out. What is interesting
here is that two respondents gave nuanced negative and positive replies for the same reason.
Moritz Hentschel, 441663 – Master Thesis

Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
While disagreeing whether cooperation in general at the Port is normal or not, both replied
independently from each other that within proximity cooperation is normal, whereas
cooperation on a large scale is still not common.
Interestingly, these results indirectly confirm Porter’s definition of clusters as "geographic
concentrations of interconnected companies and institutions in a particular field" (Porter, 1998,
p. 78). Interviewees agreed on the significant synergetic potential regarding energy matters at
the Port due to the geographic concentration of companies with complementary assets (i.e.
roofs, energy consumption). However, the respondents were reluctant to call the Port an energy
cluster since they witness a lack of interconnection (large scale cooperation). Accordingly, the
Port could only be called an energy cluster, if there was both geographic concentration of
companies with synergy potential regarding energy matters and an element of interconnection
among these companies. Consequently, by allowing companies at the Port to become
interconnected on energy matters, a REC could in fact be the missing piece of the puzzle that
would make the Port an energy cluster. To conclude, this confirms the second assumption of
the literature summary model, since apart from increasing the likelihood of solar energy
deployment, a REC would also lay the foundations for an energy cluster at the Port, which in
turn would facilitate cooperation on energy matters in general and thereby enhance the impact
of the cooperative.
7.2 Action plan recommendation
In a working paper on how to reduce CO2 emissions in the chemical industry through
electrification, VoltaChem, a Dutch organization whose mission is to connect the chemical
industry to the electricity sector, puts forward an inspiring vision for a more sustainable
chemical industry (Figure 8). Since the Port of Rotterdam is one of the major European hubs
for the chemical industry (Herder and Stikkelman, 2004), this figure can be used as a starting
point to discuss how to launch a REC at the harbor.
Moritz Hentschel, 441663 – Master Thesis
94
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
Figure 8 - VoltaChem’s dream of a sustainable, circular chemical industry
Figure 8 shows that one of the crucial prerequisites for a sustainable future within the chemical
industry – or any other industry - is an abundant supply of renewable electricity. It is evident
that electrifying the chemical industry with electricity that is generated by conventional
methods does not lead to a more sustainable future. Consequently, one of the first questions a
business community of an industrial zone, such as the Port of Rotterdam, must answer is: how
are we going to increase the supply of renewable electricity? As has been outlined at the
beginning of this thesis that solar energy is one of the low hanging fruits for the Port to achieve
this goal.
The results of this thesis indicate that in the case of the Port, a REC could indeed lead to a
higher deployment of solar energy. Furthermore, research shows that the industrial zone at the
harbor has a high potential to act as energy cluster, which could increase the impact of the REC
on solar energy procurement. Consequently, the circumstances for a REC to achieve the goal
of a more sustainable Port are given. Now, the important task is to launch the cooperative in
such a way that it has a high potential to succeed.

Based on the 14 existing and potential characteristics of RECs as well as several of the
additional insights presented above, the researcher could formulate an action plan on how to
launch a REC at the Port (Figure 9).
Figure 9 shows that the results of this thesis can be classified into four steps of the launching
process: how to start, with whom to start, how to manage (once started), how to continue (in
the future). Within each step, there is one result of particular importance that has been
highlighted. Additionally, two results have an impact on results of another step in the launching
process. In the following, the action plan recommendation is explained in more detail.

7.2.1 How to start?
Intensive communication
Before the official launch of the REC at the Port, the founders of the cooperative should prepare
well. Research has shown that intensive communication with relevant stakeholders is required
before the launch. Companies that could be potential founders should be identified and then
motivated to join the project by explaining them the benefits of the REC. Once they are inclined
to become founding members, an agreement regarding the following topics has to be reached
before the launch:
Inspiring mission
The cooperative’s mission should be composed of a mix of financial and societal targets. It is
important that it is conveyed clearly by the founders that the organization’s aim is to build a
more sustainable business environment and to enable its members to earn money by cooperating
on energy matters at the same time. The business community at the Port should develop the
feeling that a new era begins where affordable and green electricity becomes the norm.
Inclusive name
Additionally, the cooperative should receive a name that conveys a feeling of inclusion and
unity. The name should show that the goal of the cooperative is to unify the resources of the
entire business community at the Port to create a more sustainable and financially attractive
electricity procurement system for all parties involved.
Create trust
It will be decisive whether the REC will be able to convey a feeling of trust among the Port
community. Research has shown that companies at the Port will question the cooperative’s
effectiveness as well as its ability to handle sensitive data. To overcome these two barriers, the
cooperative must address this trust challenge actively from the start.
To prove its effectiveness, the REC should initiate its public appearance by presenting a strong
and simple business case. Given that in the beginning, companies will not be willing to invest
a lot of time in the project, such a business case must contain a specific starting project that is
easy to understand (simple and compelling financial calculations) and through which the
mission of the cooperative becomes clear immediately. Additionally, the first project should be
Moritz Hentschel, 441663 – Master Thesis
97
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
easy to implement, so that fast success can be generated, which would send a strong message
of effectiveness. In fact, launching the REC with a specific starting project that is easy to
implement is in line with research on agile project management methodology, such as the Scrum
approach. By breaking down large software development projects into “a list of smaller
deliverables” (Cocco et al., 2011, p. 3), developers applying the Scrum approach are less likely
to be overwhelmed by the complexity of the entire task and are able to advance in their work
step by step, while remaining agile in the face of changing circumstances. Similarly, by
launching the REC with a simple and concrete starting project, the cooperative might be more
successful in motivating companies to join, since the first steps would seem manageable and
promising. However, if the cooperative started by presenting a complex business case including
the full scope of activities a cooperative could perform at the harbor, the Port community might
get the impression that joining the cooperative would lead to too much work and that tangible
results might never be achieved. Interestingly, agility has been named as an important
characteristic in phase I, but did not make it past the pertinence threshold of the second phase.
Finally, making fast success visible should also be an important element of the launching
strategy, since visible success creates confidence in the cooperative’s ability to deliver results.
Rebutting the second prejudice will be more difficult, since a certain period of successful
cooperation has to pass before companies will be convinced enough to share data with the
cooperative. Consequently, the first step should be to engage companies as members, even if at
first they are not willing to share data on, for instance, energy consumption. To achieve this, a
clear organizational structure and roadmap should be presented showing potential members that
their participation will not force them to disclose sensitive information and that cooperation can
be started on a simple level. Additionally, becoming a member should not force companies to
invest in projects that the cooperative develops. This is common practice among professionally
organized RECs and lowers the entrance barrier significantly.
In subchapter 7.4.2 on practical implications, a suggestion for such a concrete and simple
starting project, which would not involve much information sharing will be presented.
Moritz Hentschel, 441663 – Master Thesis
98
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
7.2.2 With whom to start?
Port Authorities
One of the most important characteristics of the REC should be that it is fully supported by the
Port Authorities. In fact, the Authorities should be one of the most active founding members of
the cooperative. This will increase significantly the trust of potential members into the REC as
well as its awareness level among the port community.
Visionary Leadership
Furthermore, founding companies should have a visionary leadership. This will give them the
necessary perseverance to confront the skepticism they will encounter and to navigate the
cooperative through the rough waters of its founding. Founding members must understand that
in the case of energy at the Port through cooperation higher profitability can be achieved, even
if this goes against the conventional Machiavellian conception of rivalry and competitive
advantage. Additionally, according to Varadarajan and Cunningham (1995), it will be easier to
convince companies with visionary leadership to become a founding member of the REC. The
authors state that top management attitudes affect a firm's propensity to cooperate, since trust
among top level management will help to share knowledge and resources with other companies.
Finally, founders of the cooperative (i.e. the people organizing the launch, not the founding
members) should possess an entrepreneurial spirit, since they will have to conceive creative yet
robust business cases that will have to be defended against the above-mentioned skepticism of
the Port community.
Large size and external investors
Even though research phase I has shown that most RECs have been founded by six entities or
less, in the case of the Port it seems that a different approach is necessary. Many interviewees
of phase II stated that energy at the Port is a topic that must be addressed on a large scale and
therefore there should be many participants. Consequently, it should be considered to launch
the REC with a larger number than six founding members. Still, it should be made sure that the
initial size does not become too big so that the cooperative is still able to remain agile in the
beginning. Additionally, one of the founding members should be a company with a certain
weight at the Port, since this will convey a feeling of security to smaller companies, which will
attract new members. Finally, since the aim is to achieve large scale changes within the Port
area, which will require high initial investments, the cooperative should remain open to external
Moritz Hentschel, 441663 – Master Thesis
99
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
investors to finance projects. It has been warned throughout both research phases that this could
erode the concept of a REC, however other interviewees stated that it will be necessary to
engage external investors if large scale projects shall be achieved. In the eyes of the researcher,
cooperating with external investors does not necessarily erode the concept of a REC - especially
in the case of an industrial cooperative - if it is made clear to everybody that the main goal of
the organization is to enable cooperation on energy matters among the Port community and that
its first aim is to bring benefits to its members. Or as one interviewee stated: “[what matters is]
where the project is located, not who finances it”.
Matchmaker and resource pooling
Many interviewees have stated that the cooperative should act as a matchmaker between
companies whose demand for and supply of resources is complementary. This is in line with
research on strategic alliances, where it is stated that the ability to pool resources is an important
motivational factor in the formation of a strategic alliances (Das and Teng, 2000).
Consequently, the REC should start its existence by inviting companies with such
complementary resources to join and to engage in prosuming activities. This will make it easier
for the cooperative to present a strong business case since it will identify untapped resources
and make them available where they have the highest economical value. Additionally, the REC
should pool the resources of its members to achieve scale effects and to have access to markets
to which they would not have access to on their own. The ability to act as matchmaker and to
pool resources will be a crucial element of the REC’s raison d’être. Valuable lessons on how to
achieve efficient matchmaking, for instance by sending the right price signals to the right
parties, can be learned from the insights gained through the Power TACs (Ketter et al., 2013).
7.2.3 How to manage?
Efficiency and professionalism
Research has shown that a REC at the Port of Rotterdam would have to be managed efficiently
to gain the trust of the port community, which would be crucial for its continuous existence.
Resources would have to be spent in such a way that maximum impact is reached, projects
would have to be executed fast and effectively and a strategic marketing campaign would have
to be put into place to establish the REC as an accepted and valued member of the Port
community. Achieving this goal will require a professional management. Most RECs are
managed by its members and on a voluntary basis. This would not work for an industrial REC
Moritz Hentschel, 441663 – Master Thesis
100
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
at the Port. At least one FTE would have to be employed from the beginning. One respondent
even stated that it would be better to employ up to three people from the start so that the whole
responsibility would not have to be carried by one employee. In the beginning, the REC will
not generate positive cash flows, therefore a membership fee should be collected from new
members to finance the overhead of the cooperative. It would have to be decided whether a
one-time fee or a yearly fee should be charged. Additionally, it would have to be decided
whether the cooperative should differentiate among members. The NDSM cooperative, for
instance, charges fees depending on to the number of employees a member has. Furthermore,
the cooperative should make sure to design its business cases in such a way that a sustained
cash flow is generated that flows back into the cooperative so that after a certain time, the REC
would be able to finance itself. Finally, to keep the organizational structure lean and
membership fees low, the cooperative should always focus on its core capabilities and mission,
which is organizing cooperation regarding energy matters. Therefore, other activities, such as
project development and project implementation should be outsourced to existing firms. Since
the REC will have higher leverage than individual companies, the cost of market contracting
will be minimized and better conditions will be achieved than when each company would have
to negotiate on its own. This is an important benefit RECs can bring to a community, which is
in line with the literature on RECs stating that cooperatives minimize the costs of market
contracting (Huybrechts and Mertens, 2014).
Separate legal entity
Since launching a professionally managed REC would require its founding members to invest
capital, it is important to make sure that the cooperative is set up as an impartial entity so that
no member has to fear that the cooperative follows the interest of a certain stakeholder.
Therefore, the REC would have to be set up as a legal entity that operates separately from but
is nevertheless owned and controlled by its members. Research on strategic alliances supports
this characteristic, since Parkhe's (1993, p. 795) definition of strategic alliances, describes them
as "relatively enduring interfirm cooperative arrangements [...] that use resources and/or
governance structures from autonomous organizations, for the joint accomplishment of
individual goals linked to the corporate mission of each sponsoring firm". Additionally, creating
a separate legal entity would avoid issues of cartel building, since companies would not
collaborate with each other directly, but via a commonly owned, third party that has been set
Moritz Hentschel, 441663 – Master Thesis
101
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
up with the official purpose to facilitate collaboration on energy matters. Finally, creating a
separate legal entity would help building a compelling story and presenting a clear
organizational structure to potential members, as explained above.
Smart voting mechanism
Most cooperatives apply the one man one vote voting mechanism, which allocates one vote to
each member, independent of this member’s importance within the organization. Even though
many interviewees, especially those of phase I, claimed that this characteristic is crucial, many
others stated that applying such a rule within an industrial cooperative would not work. Those
supporting the rule argue that it creates a feeling of trust and familiarity among members, which
is one of the most rudimentary aspects of a cooperative. Those arguing against it state that
companies are used to systems, where more investment of time and money leads automatically
to more influence within an organization and that they would not want to engage in a
cooperative that functions otherwise. To the researcher, both arguments sound compelling,
even though it must be noted that the NDSM cooperative, which is a purely industrial
cooperative, applies the one man one vote rule. However, it must be added that the NDSM
industrial zone is composed of a significantly different business community than the Port of
Rotterdam, with a very diverse ecosystem and many companies that work in creative industries.
Therefore, this experience might not be transferable to the Port of Rotterdam business
environment, which has been classified as highly pragmatic and not as creative. Confronted
with these two opposing views, many interviewees replied that the voting mechanism should
eventually evolve out of a negotiation process of the founding members. Additionally, it has
been argued that a smart voting mechanism would have to be developed, which is not
necessarily linked to the financial possibilities a member has, but more to the amount of
resources a certain member is able and willing to dedicated to the cooperative.
7.2.4 How to continue?
Successfully launching the cooperative is only half the work. If a real change of the energy
supply of the Port is to be achieved, a REC would have to operate for a long time. Based on the
results of this thesis, certain recommendations can be given on how to achieve this goal.
Moritz Hentschel, 441663 – Master Thesis
102
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
Keep the “fun factor” alive
Next to financial benefits, being part of a progressive movement that creates a better future will
be one of the main motivating elements for companies to join the cooperative. This feeling of
being part of a revolution that creates a smarter and more sustainable business environment
must be held up by the cooperative. One interviewee called this aspect fittingly “keeping the
fun factor alive”. This does not mean that the cooperative should not be serious in its work. It
rather means that a constant feeling of progress and innovativeness should be created, triggering
the kind of out of the box (yet realistic) thinking that motivated companies to join in the first
place. One interesting idea that came up throughout the research could contribute to this feeling
significantly: allowing employees access to the cooperative. As long as this does not disturb the
efficient functioning of the REC, giving employees the option to invest (maybe even to vote)
in projects of the cooperative, could spur a feeling of revolution in which all stakeholders at the
Port are involved. Consequently, the Port’s energy supply would not only become more
sustainable, its profits would also remain local, fitting the purpose of decentralization, which
has been discussed in previous chapters. Additionally, as outlined in Chapter 2, successful
RECs enhance the social cohesion of its members (Pezzini, 2006), which can lead to the
creation of “a vibrant cluster [which] can help any company in any industry compete in the
most sophisticated ways” (Porter, 1998, p. 86).
Right balance between the interests of its members
It has been mentioned above that the REC should act as matchmaker between parties with
complementary resources. While creating such synergies will certainly constitute the backbone
of the cooperative’s business cases, it also bears an important challenge. Since members will
have different resources, they will also have diverging interests. For instance, roof owners will
ask for high roof rents, while energy consumers will ask for low roof rents, since the rent will
directly influence the energy price the cooperative will be able to offer. Therefore, to enable
continuous success and growth, the cooperative must put effort in finding the right balance
between the interests of its members. Fortunately, research has shown that cooperatives are a
highly effective mean to “handle conflicting interests of different stakeholders” (Rieger et al.,
2016, p. 130). A regular dialogue with all stakeholders will be as important as full transparency.
When expanding into adjacent areas, the cooperative should make sure to not engage in
activities that might harm some of its members. Members of the REC must at all times be
Moritz Hentschel, 441663 – Master Thesis
103
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
assured that the cooperative strives to achieve the best solution for all types of members,
independent of their interests and resources. Finally, keeping an atmosphere of mutual trust will
also require offering financing parties, internal as well as external, security regarding their
investments. This can best be achieved by signing long term contracts whenever possible and
by focusing on business cases that offer the possibility to create sustained cash flows for the
cooperative.
By doing this, the REC will be of significant added value, since long term contracts and
sustained cash flows will bring the kind of security, current regulations on renewable energies
lack in the Netherlands. Thereby, the cooperative will help the Port community to overcome
financial barriers to the deployment of renewables, which is in line with current research on
energy cooperatives (Morris and Pehnt, 2016).
Brand as smart city initiative
Launching a REC at the Port of Rotterdam has the potential of fundamentally changing the
energy system of one of the major ports and industrial hubs of the world. Therefore, the project
might gain a level of importance, which could elevate its impact beyond the Port area. For this
reason, one of the respondents, who had a strong focus on marketing, proposed to brand the
REC as a smart city initiative, rather than as energy cooperative. He argued that by calling
cooperative behavior to create a more sustainable future a smart city initiative, one would imply
that cities of the future should be composed of decentralized and smart ecosystems, where with
the help of big data, consumers become prosumers and the individual can assume more
responsibility for his actions. In the opinion of the researcher this is an interesting idea, which
could direct the current trend of more involved energy consumers towards a trend of more
involved citizens. However, the first goal of the cooperative should be to transform the energy
landscape of the Port. Having achieved this, branding the cooperative project as a smart city
initiative could be the culmination of successful joint efforts of the port community.
Adjacent areas
Once a first success is achieved, the cooperative should have enough leverage with its members
and the Port community to expand the scope of its activities into adjacent areas. To prepare this
step, one of the first initiatives by the REC should be to install smart meters at each building of

its members. This does not require high investments and will make it significantly easier to
identify and use synergies among its members.
In collaboration with the Erasmus Center for Future Energy Business, an activities matrix has
been developed by the researcher, which outlines other activities a cooperative could perform
(Table 10).

A detailed explanation of this matrix can be found in Table 10.
Additionally, while expanding into adjacent areas, the REC should not only focus on renewable
electricity procurement, but also on smart system integration of these unstable electricity
generators, by acting as an effective power broker, as has been outlined by Ketter, Collins and
Reddy in their publication on Power TACs (2012).
Having laid out a recommendation on how a REC could be launched at the Port of Rotterdam,
in the following, limitations of this thesis and future research topics will be discussed.
7.3 Limitations and future research
There are certain limitations to this research that must be mentioned. Some of these limitations
can serve as starting points for future research.
Moritz Hentschel, 441663 – Master Thesis

Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
7.3.1 Limitations
First, the underlying logic of this thesis (Figure 2) assumes a positive correlation between
establishing a REC at the Port of Rotterdam and solar energy deployment at the harbor.
However, since no cooperative has been set up yet at the Port, there is no prior research and no
data available to confirm or reject this assumption. Therefore, to support the Erasmus Center
for Future Energy Business in its quest to establish an energy cooperative at the Port, this thesis
had to focus on researching characteristics that would make this positive relationship more
likely. Still, it is certainly a limitation of this research that the main assumption of its literature
summary model has not yet been empirically tested.
Second, it has been pointed out by some interviewees that a cooperative might not be the best
organizational choice to organize the creation of a new energy system at the Port. In fact, the
scope of this thesis was limited to analyzing how a cooperative should be designed without
analyzing what other approaches and types of organizations could be fitting. Therefore, one
limitation of this thesis is that it exclusively analyzed energy cooperatives as a mean to increase
solar energy deployment at the Port.
Third, due to the lack of prior data on the research topic, a progressive case study has been
chosen to guide the data gathering process of this thesis. While this method proved to be an
excellent tool to gather information from scratch and to test information continuously, the
researcher had to collect and interpret this information on his own, which left room for bias.
Especially the grading threshold applied to filter the results of both research phases had to be
defined by the researcher himself. This is a limitation of this research, which has been remedied
as much as possible by the researcher through triangulation and validation techniques
mentioned in subchapter 4.6. However, since validating results is not the principal goal of the
progressive case study, other research techniques should be applied in future research to further
validate the findings of this research once a REC is implemented at the Port.
Fourth, this research has been limited to the Port of Rotterdam, which is a particular business
environment. Consequently, the results of this thesis cannot be generalized without further
research.
Moritz Hentschel, 441663 – Master Thesis

Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
Finally, the research question focused on increasing the deployment of solar energy at the Port.
However, solar energy is not the only mean to create a more modern and sustainable energy
system at the Port. While most of the recommendations outlined above can be applied to an
energy cooperative at the Port, independent of the scope of its activities, some recommendations
are expected to only apply to a cooperative aiming at increasing solar energy deployment.
Consequently, another limitation of this research is its focus on solar energy deployment.
7.3.2 Future research
Steenhuis and De Bruijn (2006) state that a progressive case study does not aim at generating a
theory that is immediately validated, but which has to be tested in subsequent research. This
thesis being a result of the progressive case study approach, plenty of ground work has been
laid out for future research. Based on the above-mentioned limitations the following most
prominent topics will be proposed.
First, since the energy cooperative will be launched soon at the Port by the Erasmus Center for
Future Energy Business, there will be data available on its impact on the harbor’s energy
system. Consequently, it might become possible to measure the impact of a REC at the Port on
solar energy deployment. It might also be possible to analyze in what way an energy cluster at
the Port might act as a mediator of this correlation. Consequently, measuring the literature
summary model outlined in subchapter 2.5 could be a topic for future research.
Second, one limitation states that cooperative might not be the only mean to increase
cooperation among companies regarding energy matters at the Port. In fact, certain interviewees
stated that other organizational forms might be more suitable to achieve such a goal.
Consequently, analyzing alternative forms of organizations, for instance joint ventures of
companies with complementary resources, could be an interesting topic for future research.
Third, since this thesis focused on characteristics a REC would have to contain to increase solar
energy deployment at the Port, it would be expedient to analyze other activities a cooperative
could perform at the Port and what additional characteristics it should develop the be successful
in these respective areas. In collaboration with the Erasmus Center for Future Energy Business,
an activities matrix has been developed by the researcher, which outlines other activities a
Moritz Hentschel, 441663 – Master Thesis
107
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
cooperative could perform (Table 10). This matrix can serve as inspiration to guide future
research on that topic.
Finally, researching other industrial zones and energy clusters that have a similar synergetic
potential could be a topic for future research. It would be interesting to analyze how cooperation
is managed in these zones and what generalizable lessons about cooperation in industrial zones
can be learned.
Having elaborated on limitations of this thesis and potential future research topics, in a final
subchapter, practical and theoretical implications of this thesis will be outlined.
7.4 Practical and theoretical implications
7.4.1 Theoretical implications
Since a REC is yet to be launched at the Port of Rotterdam, this thesis had to build theory from
scratch, leading to a variety of new theoretical insights, of which the most important ones will
be mentioned in the following.
To begin with, the researcher would like to reflect on this thesis’ research methodology: the
progressive case study approach, which was developed by Steenhuis and De Bruijn (2006). It
must be stated that in the case at hand this approach worked very well to develop new theory
on a practical question. The “continuous cycling between empirical data collection and data
analysis” enabled the researcher to advance step by step into unknown territory, to progressively
develop new theory and finally to provide relevant practical information on the research topic
(Steenhuis and De Bruijn, 2006, p. 8).
Having reflected on the research methodology, in the following, theoretical implications which
refer to the literature analyzed in Chapter 2 will be outlined.
The first implication relates to the importance of efficient brokers for the future of energy
systems. Ketter et al. (2013) have shown, that since our future energy procurement systems will
be more decentralized and scattered, efficient power brokers will be required to gather a bigger
variety of stakeholders around the supply and demand of energy. The research at hand
emphasizes the importance of such aggregators, since it found out that one of the main
characteristics of a REC at the Port should be to become a matchmaker that is able to find
Moritz Hentschel, 441663 – Master Thesis
108
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
common ground among stakeholders with diverging interests. Additionally, this research
showed that an important role of a cooperative should be to aggregate resources of its members
to achieve scale effects and to reach thresholds, which would be impossible to reach by its
members individually. This further supports Ketter al.’s (2012) argument, since it shows that
an energy transition at the Port would be much more likely in case a REC would act as power
broker among the Port community. Additionally, these results support Das and Teng’s research
on strategic alliances (2000), because they support their argument that the ability to pool
resources is an important motivational factor for the formation of strategic alliances.
Second, this thesis supports Varadarajan and Cunningham’s research on factors that influence
a firm’s propensity to engage in strategic alliances (1995). Results of this thesis lead to the
assumption that it will be easier to convince companies with visionary leadership to become a
founding member of the REC, since they will be more willing to cooperate and to trust in a
cooperative system. This reflects the authors’ argument that top management attitudes affect a
firm's propensity to cooperate and that trust among top level management will help to share
knowledge and resources with other companies.
Third, since results of this research have shown that an important benefit of RECs is that they
can negotiate with third parties on behalf of their members, support is provided for Huybrechts
and Mertens’ research on energy cooperative (2014), in which they state that one of the
advantages of cooperatives is that they minimize the cost of market contracting for their
members. Additionally, research has shown that a REC would help the Port community to
overcome financial barriers to the deployment of renewables, which provides support for
Morris and Pehnt’s current research on energy cooperatives (2016).
Fourth, this thesis supports the assumption that successful RECs enhance the social cohesion
of the environment where they are placed in, which provides support for Pezzini’s research on
renewable energy cooperatives, (2006).
The final theoretical implication touches upon the topic of energy clusters, which was discussed
in Chapter 2. As Porter (1998) and other authors have shown, industrial zones, such as the Port
of Rotterdam, offer high potential for synergies related to energy, which can make such zones
more profitable for all parties involved. This research added to this topic by showing that while
the Port of Rotterdam might indeed qualify as an energy cluster, the benefits that can result out
Moritz Hentschel, 441663 – Master Thesis
109
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
of it are not generated automatically. Since cooperation among companies within an industrial
zone such as the Port is not normal, much effort to overcome trust barriers by the business
community is needed to make use of potential synergies. In fact, such benefits can be left
untouched for a long time, if no external actor facilitates cooperation. It can thus be concluded
that energy clusters provide a fertile ground for cooperation, but that an external entity has to
help individual actors to achieve synergies by, for instance, building strong business cases
regarding cooperation. This is one of the main tasks of an energy cooperative.
7.4.2 Practical implications
14 characteristics
In Chapter 2, a literature study was performed on RECs and how they can facilitate the
deployment of renewable energies. This thesis provides new practical information, on how such
a REC should be designed in order to make achieving this goal more likely in an industrial area,
such as the Port of Rotterdam. This practical information has been outlined in the form of 14
characteristics, which shall support the founders of the REC at the Port and future founders of
RECs in similar circumstances to successfully launch a cooperative project. These
characteristics concern the general composition of the cooperative and most of them can be
applied independently of the scope of the REC’s activities. To further explain the
characteristics, they have been discussed and put into perspective through an action plan
recommendation in subchapter 7.2. Thereby, the practical goal of supporting the Erasmus
Centre for Future Energy Business in its endeavor to successfully establish an energy
cooperative at the Port has been achieved. However, since this study applied a progressive
research method, two additional contributions emerged throughout the research, which will be
outlined briefly in the following to complete this thesis.
Activities Matrix
In the first interview with the Erasmus Centre for Future Energy Business, the business director
stated that it would be helpful to develop an activities matrix to support the search for the right
scope of a REC at the Port. Therefore, in collaboration with the Center and based on Ketter et
al.’s research on Power TACs (2013), the researcher developed an activities matrix (Table 10).
The matrix shows different activities an energy cooperative at the Port could perform. The
activities are classified by the author according to riskiness and complexity. Riskiness refers to
the financial risk that is related to performing this activity. Complexity refers to how difficult
Moritz Hentschel, 441663 – Master Thesis
110
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
it would be to convince companies to perform a certain activity and then to coordinate a certain
activity. In Table 10, each activity and its placement in the matrix is elaborated on in more
detail.
What can be seen in this matrix is that bundled roof renting has been classified as the least
complex and least risky activity a REC could perform. Since this research has shown that it is
crucial to launch the REC with a specific first project that is easy to achieve and that has the
potential to result in fast success, the researcher recommends to bring the cooperative to life
through a bundled roof renting project. How this could be done in practice will be shortly
introduced in the following.
Specific example of roof pooling
The concept of roof pooling is simple and straightforward, which is why it qualifies well as a
starting project for the REC: solar project developers in the Netherlands search for suitable roof
space that they can rent to operate photovoltaic power plants on it. To initiate a roof pooling
project, the REC should do the following:
1. Sign a membership with the Erasmus University and the Port Authorities. Each new
member should pay a onetime membership fee (suggestion 8.000 €) and the Port Authorities
should be asked to provide an office within its premises. This will assign some first reputation
to the REC, which will make it easier to motivate new members.
2. Hire a general manager, preferably a young and enthusiast absolvent of Erasmus
University, which will help building a compelling story. This manager shall be responsible of
launching the roof pooling project. The salary of this manager should be composed of a low
fixed rate and success based bonuses.
3. Negotiate terms with a solar energy project developer, preferably a developer that has
references at the Port, such as Son XP. It might be considered to sign membership with this
developer to transfer ownership of the success of the project. The project development company
has to guarantee to the REC that it pays a yearly roof rent of at least 0,7 € per usable m², for
roof space that has been rented by the REC from its future members. Additionally, the developer
must guarantee that of each kWh, which is sold from roofs that have been rented from the REC,
Moritz Hentschel, 441663 – Master Thesis
111
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
a certain proportion shall be yielded to the cooperative. Thereby, the cooperative will be able
to finance itself in the long run.
4. Convince at least one company with at least 2.000 m² of suitable roof space to become
a founding member. The more companies decide to sign up in the beginning, the better.
However, the manager should make sure to only allow the amount of companies to sign up that
can be handled by the REC and its partners. The pitch of the REC towards potential members
shall be that the cooperative will rent the roof of the companies at the rate discussed above, for
15 years, no strings attached. Thereby, companies at the Port have the opportunity to earn
money with assets that have been left unused until now and to decrease their carbon footprint
without having to invest. Additionally, members will have the option to invest in projects of the
REC and to purchase the energy that is generated by the REC in close proximity to them at
market rates, eliminating grid costs. The manager should try to convince a company with a
certain reputational weight within the port community to become one of the first companies to
sign up on this proposal.
5. Having convinced at least one company with roof space, renting contracts should be
provided by the solar energy developer. Then, the renting contracts should be signed between
the companies with roof space and the REC. After this, the project developer will be charged
with developing a solar energy project on these roofs to eventually finance the project and to
operate it with the help of the SDE+ regulation. The developer should calculate from the
beginning with full sellback into the grid, since the REC might not be able to convince members
to purchase the solar energy via the postcode regulation.
6. During the project development phase, which takes several months, the manager should
approach neighbors of the roof owner(s) that signed up and offer them the opportunity to sign
power purchase agreements with the REC to purchase the cooperative’s solar energy. Via the
post code regulation, this might create more powerful synergies, which will lead to more cash
flow for the potential expansion of the cooperative.
7. Additionally, the manager should prepare an app that shows how many m² of available
and usable roof space at the Port is already rented out to the cooperative and how much potential
is left. This app should be freely available to any stakeholder who is interested in the topic.

8. Once these steps are completed and a pilot project is in the pipeline, the REC should
stage a big launching event, where it presents its pilot project and a clear roadmap of what it
wants to achieve. This gathering should be used as an accelerator to gain new members that
sign up for the bundled roof pooling.
9. The manager has to support the project developer throughout the development phase of
the pilot project and he should make sure to regularly inform all parties involved about the
status of the project. Once the project is installed, the commission should be celebrated to
increase awareness.
10. Having successfully launched the bundled roof pooling project, the REC should expand
the scope of its activities into adjacent areas. The matrix presented above can be used as
guidance. Energy purchase bundling could be a sensible next step, since the cooperative might
already have gained experience with this topic through the power purchase agreements of the
solar systems.
From here, the success of the REC will depend on efficient management and inclusion of all
stakeholders. Once the first solar systems are installed, the financial situation of the REC will
improve steadily, thanks to the cash flow it will receive from the solar system operator. With
these funds, it should be able to expand its staff to manage the cooperative’s expansion into
adjacent areas and to hopefully one day successfully lead the energy transition at the Port of
Rotterdam.

Appendix 1 - Final interview design (research phase I)
Interview RECs (Case 1 and 2)
Introduction
I am a master student at the Rotterdam School of Management and the topic of my thesis is how an
energy cooperative at the Port of Rotterdam could facilitate solar energy deployment. This energy
cooperative would be composed of companies located at the Port. Therefore, to gather data on that
subject I interview renewable energy cooperatives (REC) that have companies as members to identify
common characteristics among such RECs and to gather data concerning their opinion of founding an
energy cooperative and how it should be designed to increase solar energy.
Background information
1. Could you please introduce your organization and your role in it?
2. What is the year of foundation?
Opening Questions (motivation and goals, history and processes)
3. Reasons for foundation?
4. Short history of foundation and description of foundation processes?
Main questions (challenges)
5. Are companies involved? How?
5.1. Is it common in the Netherlands to have companies involved?
6. What are the most important characteristics of your energy cooperative? Why did you develop
these characteristics?
7. What were your biggest challenges so far?
8. Are roof/land owners among your members?
9. Do you have external investors or only internal financial funds of members?
Closing questions (recommendations)
10. Which characteristics of energy cooperatives would increase the likelihood that an energy
cooperative composed only of companies deploys solar energy?
10.1. Which new characteristics should be developed to reach this goal?

Interview companies (Case 3)
Introduction
I am a master student at the Rotterdam School of Management and the topic of my thesis is how an
energy cooperative at the Port of Rotterdam could facilitate solar energy deployment. This energy
cooperative would be composed of companies located at the Port. Therefore, to gather data on that
subject I interview companies at the Port or companies/organizations that are involved with companies
at the Port about their opinion of founding an energy cooperative and how it should be designed to
increase solar energy.
Background information
1. Could you please shortly introduce your organization and your role in it?
Opening Questions
2. Why is your company interested in installing a solar system?
3. Are energy costs an issue? How much do you pay per kWh (energy bill)?
4. How important is a green image for competitiveness?
5. How important is an innovative/smart image for competitiveness?
Main Questions
6. The Port Authorities state that there are 3.5 has of roof space that could be used for solar
energy but that solar energy deployment at the Port is still in its “infancy”. What is your
comment to that?
7. How common is cooperation among companies at the Port?
8. According to the IEA, the Port of Rotterdam can be considered an energy cluster. This
means that individual companies could benefit from each other in energy matters as if
there was larger scale. Do you agree?
9. Is an alliance regarding solar energy a feasible idea? To pool specific resources such as
roofs and energy consumption?
10. Do you think your company would engage in:
a) Roof pooling
b) Energy consumption pooling and long term energy purchase contracts
11. Would it be imaginable to form an organization taking care of that, i.e. cooperative?

12. Could you imagine paying an initial membership fee to finance the salary of a director of
this cooperative?
13. What do you think about a democratic voting system (i.e. one man one vote)?
14. How much should employees be integrated into the cooperative?
Closing question
15. In your opinion, how should an energy cooperative be designed in order to successfully
attract companies at the Port?

Bundled roof renting: In the eyes of the researcher, bundling the usable roofs of companies at
the port and renting them out as a package to a solar energy developer, represents the least risky
and complex activity a REC could perform. There is no risk involved because companies would
not have to invest, they would even receive a roof rent of approximately 0,7-1 € per usable m²
per year, for 15 years. There is low complexity involved, because companies are used to renting
out space, so little explanation is needed. Furthermore, contractual relations between the REC,
its members and the developer would be simple. This activity could be a good starting point of
the cooperative, since it would quickly generate interest among potential members and establish
a basic level of trust among founding members.
Energy purchase bundling: This activity also involves no risk, since companies would not have
to invest. Complexity is deemed to be medium, since it would be relatively difficult to convince
companies to allow a third party to look into their consumption patterns and to negotiate on
their behalf. A certain level of trust would have to be established before. Furthermore, the
financial benefits of energy purchase bundling are not clear beforehand. In fact, some
companies might already have negotiated terms with the utilities that are hard to beat by the
cooperative.
Negotiating with grid operator: The same applies to giving authority to the REC to negotiate
on behalf of its members with the grid operator (for instance to establish pricing mechanism
Moritz Hentschel, 441663 – Master Thesis
132
Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
regarding certain consumption patterns that could help stabilizing the grid). Additionally, a
certain threshold of members would have to be reached to have the necessary weight to be able
to present to the grid operator compelling arguments on what the cooperative could do for the
grid.
Energy Consultancy: This activity involves no risk, since companies would only receive
consultancy on what they could do to improve their energy consumption behavior. So no
investment needed. Complexity, however, would be high, since companies would have to trust
the REC significantly to respect its recommendations on energy matters. Furthermore, financial
benefits are difficult to predict.
Financing of RE power plants: Financing renewable energy projects is deemed to be medium
risky. Members would have to invest, which increases risk. However, the investment would not
have to be high per member, since external investors (such as green investment funds) could
provide the majority of the own capital needed. Complexity is medium, since contractual
relations between many parties would have to be arranged (roof/land owners, internal investors,
external investors, REC, project developers etc.) and members of the REC would have to trust
the cooperative enough to make an investment. Still, complexity is deemed to be medium, since
the coordination would only have to happen once, during the project development and financing
phase. Afterwards, most of the power plants would not need any more attention from most of
the stakeholders. The same applies to establishing a virtual power plant (VPP), which would
be a logical next step and initially mainly consist of installing smart meters and controlling
devices at each renewable power plant and bundling them virtually as one bigger power plant.
Demand side management: DSM by itself does not require a lot of investment. However, it
often requires changes in consumption patterns, which, in the case of companies, can amount
to changes in production patterns. Since the change in production patterns can lead to financial
losses as companies and their customers, partners and suppliers might have to get used to the
new status quo, the risk is medium. Complexity is high, since changing production patterns is
a time and management attention consuming undertaking. Furthermore, if companies at the Port
start operating according to new patterns, this can disturb supply chains. Due to theses dangers,
companies would only consider engaging in DSM if they had a high level of trust in the entity
organizing it and if financial benefits are significant.

Erasmus University Rotterdam - Supervising Professor: Prof. Dr. Wolfgang Ketter
Financing of storage: Risk would be high, since investments would be required and payback
periods for storage solutions are relatively long. Especially compared to investments in RE
power plants, storage solutions are currently less cost effective. With regards to complexity, the
same argumentation as in the case of financing RE power plants applies.
Local utility: Establishing a local activity can be seen as the summit of energy cooperation at
the Port. However, due to strong incumbents and very high investments as well as thresholds
of participants required, risk and complexity are high.
