Overview

Ladies and Gentlemen,

Over the past decade, renewable energy generation in Germany experienced an increase which was ten times higher than the OECD-aver-age. As a result, renewables cover almost 25 per cent of Germany’s electrical energy provided through the middle of 2012, compared with a share of substantially less than 10 % in 2000. The driving force behind this develop-ment was, above all, the political strategy followed since 2000, deciding on phasing out nuclear energy and setting ambitious climate change objectives. The events at Fukushima in 2011 accelerated the process.

The German policy striving for the promotion of renewable energy also has its drawbacks. Alongside a significant growth of wind energy, the Renewable Energy Act (Erneuer-bare-Energien-Gesetz, EEG) led to an explosion in installed solar power in Germany over the last three years. Photovoltaics consume roughly half of the EEG budget, but - due to the unfavourable solar radiation condi-tions in Germany - supplies only one fifth of the total renewable energy.

Keeping in mind corrective actions resulting from undesirable develop-ment and learning from negative and undue impacts, such as unrestrained growth of solar energy, Germany’s experiences can help other countries use their own renewable energy resources more effectively.

For energy supply systems integrating renewable energy, the early prepara-tion of an overall concept – also called energy master plan – is a prerequisite to create the necessary planning structure and certainty required by the state and private investors. In Germa-ny, it was learned that the lack of such a master plan was one of the main reasons for the undesirable develop-ment mentioned.

An effective energy master plan is, in the first step, based on an analysis and forecast of demand. When focussing on the electricity sector, the technical and economical potentials of renewa-ble energy should then be defined and mapped. The energy master plan should also consider suitable sites and the future infrastructure for the distribution and transmission of electricity as well as back-up capacity

from conventional power plants or from storage systems (e.g. pumped-storage plants).

The tariff framework for these systems and the development of a roadmap for implementation should not be forgotten.

In the current issue of our magazine “aktuell” we present our work as partner relating to the planning and development of measures in the renewable energy sector and in many other related fields. With this, we are proud to be making a significant contribution to making our world a more liveable one.

Sincerely,

Dr. Bernd Kordes

Looking Back: Trade Fairs 2012

Lahmeyer Successfully CertifiedThe new diN EN iso 9001:2008 certificates were submitted to lahmeyer by TÜV Hessen in october. They are valid for another term of three years, up to 2015. At the same time, the number of group members working in conformity with these standards has increased.

In the certification audit, the TÜV auditors called Lahmeyer a very powerful company, organised with clearly structured processes. “The quality specifications have been implemented in an exemplary manner by all employees”, confirmed Mr. Volker Rühl, Lahmeyer International’s quality manager. Lahmeyer guides projects from initial ideas through to success in a professional and highly competent manner – sustainability and the creation of values in the interests of the clients go without saying.

increasing Number of Certified EntitiesAlong with last year’s successful re-certification of the QM system, the group members already working in conformity with these standards, namely Lahmeyer Berlin and Lahmeyer Munich, also Lahmeyer GKW Consult and the Lahmeyer Branch Office in Abu Dhabi now fall under the matrix certification of Lahmeyer International. The subsidiaries Lahmeyer Rhein Main and Hidro Dizayn have own certifica-tions following DIN EN ISO 9001:2008.

QuAliTY MANAGEMENT

The Abu dhabi Branch officealso obtained a QM Certificate.

In 1994, Lahmeyer International installed a quality management system (QMS) covering the divisions energy, water, as well as building and transportation.

Thanks to the longstanding experience and consistent application of the process structures defined by QMS, there is an optimum time schedule and adequate budget for every project.

showcase Fair for Wind EnergyIn 2012, Lahmeyer International was again represented with a stand at the Showcase Fair Husum WindEnergy in Husum, Germany. With wind energy projects in more than 55 countries under close engineering supervision in the fields of planning, award, imple-mentation, and operation, Lahmeyer ranks among the world’s leading tech-nical consultants in this sector.

success at power-GenThe Power-Gen Trade Fair and Congress Event in Cologne was dedicated to future energy supply. As experienced partner in the realisation of power plants and power grids, Lahmeyer International presented its extensive range of services. “We have intensified our contacts and established new ones”, Michael Wünnemann, Depart-ment Head for Thermal Power Plants, indicated his satisfaction with the pro-ceeding of the fair. “European partners as well as our most important clients from Saudi Arabia and other countries visited our stand.”

panel discussion on AfricaThe question, whether “Clean Energy in Northern Africa“ will be a new market was 2012 the focus of attention for a panel discussion of the German-African Business Association in Munich. Mr. Kuno Schallenberg, Department Head for Renewable Energy within Lahmeyer International, was one of the seven par-ticipants. He confirmed that projects, such as Desertec show a change in the way of thinking in northern Africa. In this way, the business fields specialised by him – photovoltaics, solarthermal energy, biomass, geothermal energy, and small hydropower plants – gained further importance. All panellists agreed that, according to their current experience, there are positive business prospects.

Joint Contract for the Pumped Storage Scheme KemahThe daily lives of millions of citizens, as well as the industry and economy of Turkey, depend on a stable power supply. power failures can have far-reaching impacts. investigations of pumped storage plants (psps) in Turkey are therefore currently in progress to determine the feasibility of such schemes operating in pumping or standby mode outside peak demand periods. A joint venture between lahmeyer interna-tional and Hidro dizayn is preparing tender designs for the Kemah psp.

View from downstream of the main dam site in the Firat River gorge, Turkey

Threat becomes RealityOn January 14th, 2012, some 20 million people experienced a system-wide loss of power resulting from the failure of the 1,400 MW Bursa Natural Gas Combined Cycle power plant. Complete heating and transport systems as well as the industrial infrastructure came to a halt in the middle of a harsh winter, with major social and econom-ic consequences.

The authorities have stated that these impacts could have been avoided, had the regional power infrastructure included pumped storage plants (PSPs). Where solar and wind-generated energy comprises a significant proportion of the power “mix” integration of PSPs is essential for balancing out the different periods of regenerative energy generation and the timing of consumer demand.

project developmentThe Kemah project on the River Firat is to be developed in two stages. The upper stage, with an effective head of 70 m, is planned with an installed capacity of 180 MW, either as a conventional hydropower plant or as a PSP. If the PSP option is chosen the lower stage will be developed as the lower reservoir. A smaller dam 8 km downstream of the main dam would utilise 30 m of head in an integrated conventional hydropower station with an installed capacity of 58 MW.Agriculture would also in future ben-efit from the project, using turbined water for irrigation of the surrounding fields.

Tender designs for the complete scheme, with a combined capacity of 238 MW, commenced in April 2012.

Lahmeyer and Hydro Dizayn are providing engineering services in joint venture to the Client – Ak-El Kemah Elektrik Üretim A ,S for both the design and investigations phases of the project.

The project can utilise a combined gross head of 100 m. Full Supply Level of the upper reservoir would be at 1,135 m above mean sea level (amsl). Rapid fluctuations in water level are to be minimised in order to avoid both risks to the population and damage in the valley downstream of the lower barrage. In addition, the entire scheme will be designed to remain safe under severe earthquake conditions.

Topographic and bathymetric survey campaigns have been completed and the geological investigations are in progress.

The joint venture team has studied ex-isting geological and geotechnical re-ports, and prepared interpretations in respect of the stability and watertight-ness of the reservoir. The previously proposed concept was reviewed in the Value Engineering Report, in which alternatives were also formulated. One of these options will be selected for the tender design work.Akcaru, Burgehan

Punjab Province, situated in the north-east of Pakistan, is one of the most agriculturally developed provinces in which the globally popular Basmati rice is cultivated on a large scale.

Our project team in Lahore consists of more than 20 international and national experts from various disciplines, especially in the fields of water resource engineering and hydrogeology.

The project is programmed to last for two years and be completed in 2013. Project development is performed at all times in close collaboration with the Irrigation Department of the Government of Punjab.

Within the framework of the project a groundwater model has been applied to forecast groundwater levels, as an input into the development of sustainable management strategies for the groundwater resources.

Agriculture in Pakistan is dependent on large irrigation systems as a result of the prevailing hot climatic condi-tions. Many of these irrigation systems were planned and implemented at the end of the nineteenth century during the British colonial period.

The irrigation systems in Punjab Province consist of open channels with varying capacities. Due to the rapid increase in demand for agricultural products there is not enough surface water, and more water is being extracted from groundwater sources.

This has resulted in an over-exploita-tion of valuable groundwater resourc-es, and is exacerbating quality problems, since the older existing groundwater resources already have a high salt content and are thus limited in their use for irrigation.

To deal with the problem the Govern-ment of Punjab Province is promoting the sustainable use of groundwater resources, and this forms a part of the rehabilitation of the Lower Bari Doab Canal system.

Lahmeyer International together with its Pakistani partner, National Develop-ment Consultants, was awarded the contract for the monitoring and modelling of the groundwater resources of the Lower Bari Doab Canal system, and the development of strategies for groundwater manage-ment by the Government of Punjab. The project is funded jointly by the Asian Development Bank (ADB) and the Government of Punjab.

pAKisTAN

A consequence of the rising world population and scarcity of water resources is that efficient water management is becoming increasingly important. lahmeyer international is supporting the Govern-ment of punjab province in pakistan in developing strategies for the efficient and sustainable use of groundwater resources.

Sustainable Use of Groundwater Resources for Irrigation

A Geographic Information System (GIS) coupled with a relational database has also been developed in order to establish a better basis for water management. Comprehensive groundwater management policies are currently being developed to protect the groundwater resources for future generations.

To ensure the quality of the data, extensive field studies were carried out with the help of various appropri-ate technologies such as GPS, analysis of satellite imagery and geo-electrical resistivity surveys.

The project is making an important contribution to the sustainable use of water resources in the Province of Punjab in Pakistan, and will help to ensure the availability of sufficient water supply for future generations.Dr.-Ing. Axel Braxein,

Feasibility Study for Largest Hydropower PlantAlong with the gradually developing economy of sierra leone, a country rich in mineral resources, the availability of a sufficient and reliable energy supply becomes ever more important. The only hydropower plant of any size is located at Bumbuna. This plant is to be expanded in order to satisfy the growing energy demand, for which lahmeyer international has prepared the feasibility study.

With a total installed capacity of 80 MW and an annual energy production of 22 kWh per person, Sierra Leone is a country with one of the lowest levels of specific power generation per capita worldwide. Of this total, a capacity of 50 MW is installed alone at the Bumbuna Dam. This plant on the Seli River in the North-East of the country was designed already in the 1970s, with construction being able to start in the 1980s. Problems with the financing and the effects of the 1991 to 2002 civil war led however to frequent interruptions in construction, so that the plant was finally commissioned only at the end of 2009.

Already at that time an expansion of the plant in stages was under consider-ation. In the meantime it could not be ignored that the future power demand would continue to grow. In order to address this requirement the Govern-ment of Sierra Leone has established a Public Private Partnership with Joule Africa, an international investment company focusing on the development of power generation and supply in Africa. professional project supportJoule Africa initially engaged Lahmeyer International in June 2011 to prepare a pre-feasibility study for Phase II of the Bumbuna Hydropower Project. The contract for the preparation of the full feasibility study followed in September 2011. The feasibility study includes not only the design of the project works, but also the establishment of the topography of the project area, preliminary geotechnical investiga-tions, as well as the preparation of an environmental and socioeconomic impact report and the development of the associated mitigation programmes.

Lahmeyer submitted the feasibility study in September 2012, and tender documents were prepared – on the basis of the feasibility study – for implementation by means of an EPC contract (Engineering, Procurement and Construction). Lahmeyer will continue to provide support to the Client at least until this construction contract has been signed (foreseen to be within the first half of 2013).

Future capacity increased four-foldThe Bumbuna Hydropower Project comprises two power plants. Water will be diverted from the existing reservoir via a 2.4 km long tunnel to run four tur-bines, each having a capacity of 33 MW. A 1.6 km canal returns the water to the

river. This diversion arrangement thus bypasses the Bumbuna Waterfalls, and thereby increases the available hydraulic head by 40 m to a total of 112 m.

The second power plant will be located 32 km further upstream, at the head of the backwater from the existing Bumbuna Dam reservoir, where the 85 m high Yiben Dam is to be constructed. The significant improvement in flow regulation provided by the associated new reservoir (with a storage capacity of 2 km3), and the installation of two 33 MW turbines, will result in an average annual power production from the whole project of 810 GWh – four times the nominal production capacity of the existing plant.Dr. Jens Mödinger, Bernd Metzger

Forbach Pumped Storage Plant developing for the Future

Ausschnitt aus landnutzungskarte

The plant is located along the Murg River near Forbach village and was developed in two stages between 1914 and 1926. Major components are still in their original condition. It consists of several individual power plants: a low-pressure power plant of 2.2 MW, Raumünzach plant of 550 kW, Murg plant of 22 MW and the Schwarzen-bach plant of 43 MW including various reservoirs, among them the Schwarzenbach dam with a usable storage volume of 14 mill. m3. The expansion is planned to optimally utilize the existing hydropower infrastructure at Forbach and the existing reservoir of the Schwarzen-bach dam.

Effective solutions proposedBetween 2007 and 2010, Hydroprojekt Ingenieurgesellschaft - in cooperation with Lahmeyer - carried out several

studies in order to determine the possibilities for rehabilitation of the RFW and also the potential for pumped storage plants in the area near Forbach village. In the years following, Hydroprojekt prepared the technical documentation for the regional planning procedure for the Forbach pumped storage plant.

The gained solutions cover the construc-tion of two new pumped storage plants above and below the Schwarzenbach dam (upper and lower scheme). The upper scheme comprises the new con-struction of a 200 MW pumped storage plant with underground powerhouse and a gross head of approx. 319 m. This will use the Schwarzenbach dam as lower reservoir and a new upper reser-voir will be built on the near “Seekopf” hill, formed by a circular embankment with approx. 2 mill. m3 storage volume.

For the lower scheme, the existing Schwarzenbach plant will be replaced by a new 70 MW pumped storage plant in shaft construction with a gross head of approx. 360 m. In this case, the Schwarzenbach dam will serve as upper reservoir, the lower reservoir will be the existing Forbach compensation reservoir, being expanded to approx. 0.6 mill. m3 of usable storage volume by means of an underground water reservoir.

In August 2012, the JV PSW Forbach was awarded the contract for the design and approval planning with an option for subsequent engineering services during construction. The joint venture consists of Hydroprojekt Ingenieurgesellschaft mbH, taking the lead of the JV, and Geoconsult ZT GmbH and Lahmeyer International GmbH.Robert Achatz

The EnBW Kraftwerke AG operates the Rudolf Fettweis Hydropower plant (RFW) at Forbach in the Northern Black Forest. it is planned to be rehabilitated and expanded in a future-oriented manner. Together with lahmeyer international, Hydroprojekt ingenieurgesellschaft investigated possibilities for rehabilitation of existing plants and the potential for additional pumped storage plants in the surrounding area. The involved experts will also perform design and approval planning for the project.

Water Supply for Yaoundé from the Sanaga RiverThe population of Yaoundé, the capital of Cameroon, is growing continuously and currently stands at more than two million. The demand for water is growing with the population. planning has already been prepared for connection to a new source of water, the documentation of which will help the Government with decision-making on future steps.

The Ministry of Energy and Water Resources is continuously extending Yaoundé’s water supply and wastewa-ter infrastructure for the Ministry of Energy and Water Resources. However, satisfaction of the increasing demands has reached the limits of the current sources, so that new options for sustainable water supply have to be identified.

Studies with a 2035 planning horizon have shown that the most economical way to satisfy the increasing demand will be to use the River Sanaga, some 75 km from Yaoundé.

This major water supply project will deliver 315,000 m3/day of water with a static head of 100 m and should be completed by the end of 2015. The project includes, amongst other components, intake works, a raw

water pump station, a water treat-ment plant and two booster pump stations, as well as administration buildings and staff accommodation (for details see box).

Tight programmeThe project is to be implemented as an EPC contract (Engineering, Procure-ment, Construction) with Chinese financing. The Ministry of Energy and Water Resources contracted Lahmeyer International to carry out a critical review of the EPC proposal, with a focus on its technical, environmental and financial feasibility. Particular value was placed on technical improvements to the intake works and pump stations. Lahmeyer’s responsibil-ities also included evaluation of the scope for reduction of investment and operational costs and for optimisation of the construction planning.

In view of the urgency of the project and its tight timeframe, Lahmeyer’s team of engineers carried out a rapid assessment and in August 2012 presented alternative recommenda-tions to the responsible authorities in Cameroon.

The documentation prepared by the team for the Ministry of Energy and Water Resources now serves as an important tool to support their decision-making.Bernd Metzger

While remnants of the financial and economic crisis continue to have significant influence on market growth in numerous regions around the world, many Near and Middle Eastern countries have documented a return of economic growth and superlative. A considerable number of gigawatts of power plant capacity and thousands of kilometres of cable and line are installed annually in order to meet the rapidly growing demand for electrical energy. lahmeyer international is active in this region and is also locally positioned in all three core segments of power generation and distribution – in some of these countries and technologies as a market leader: regarding the construction of large thermal power plants, the emerging market of renewable energy and the expansion of power grids.

NEAR ANd MiddlE EAsT

Near and Middle East Forecasting Market Growth

ENERGY

The overall installed capacity of this region is approx. 170,000 MW with an annual consumption of electrical energy of about 570 TWh – both showing fast growth. As concerns the electricity sector, the countries of Saudi Arabia, Egypt, Iran and the United Arab Emirates (in this sequence) are of particular importance.

The region’s strong economic dyna-mism is primarily based on the income from oil and gas business, as a number of the most important countries for oil and gas exports in the world can be found here.

A considerable portion of this income is invested in expansion of the electricity sector. Ambitious plans for power plants and grid expansion result in part therefrom.

This becomes particularly clear with Saudi Arabia. Following the plans of the Saudi government, an installed plant capacity totaling 50 GW of thermal and fossil-fueled power is foreseen to be installed in this country by 2020, a total of 51 GW of renewable energy plants is foreseen to be installed by 2030.

The latter 51 GW include 41 GW gained from new photovoltaic and solar-ther-mal power plants. Thus, Saudi Arabia may evolve into the world’s largest market for solar power outside Europe and the USA in the coming years.

lahmeyer‘s presence in the Region Lahmeyer International has been active in the region for decades. Under the direction of Lahmeyer, power plants and/or grids have been installed in all countries, and also today Lahmeyer’s engineers play a full and active role. The majority of their current activities are concentrated in Saudi Arabia, Abu Dhabi, Qatar, and Egypt – countries, in which Lahmeyer International is also locally positioned with own entities:

The Abu dhabi branch office exists since the 70‘s; approx. 90 employees are presently working, almost exclu-sively, on projects relating to grid planning and new construction / expansion of grids. Lahmeyer’s business in Abu Dhabi is complemented by various mandates in the field of renewable energy on behalf of the clients Masdar and TAQA.

Lahmeyer also has a legal subsidiary in saudi Arabia, located in Al Khobar, with 32 local and international employees currently working here.

The Qatar branch office was founded in 2007, which, in 2011, was converted into an independent subsidiary. As in Abu Dhabi, the activities of their 67 employ-ees concentrate on electrical grids.

Since the 90’s, Lahmeyer International has also a subsidiary in Egypt, carrying out water and energy projects as well.

The Market: Near and Middle East The term “Middle East“ applied in common international practice is often overlapping with “Near East” in the German language. From a geographic viewpoint, the “Near East” essentially includes the states on the Arabian Peninsula, Egypt in the South-West as well as Iraq and Iran in the North-East.

In total, we refer to a region with an area of about 6.3 million km2 incorpo-rating approx. 263 million people. To have a comparison: the European Union covers an area of about 4 million m2 with 492 million inhabitants.

Qurayyah Gas-Fired power plant in saudi Arabia

The following paragraphs introduce a series of major projects, currently ongoing or recently completed.

Thermal power plantsQurayyah Combined-Cycle power plant in saudi ArabiaThe Qurayyah project on the east coast of Saudi Arabia comprises several installation phases of a combined-cycle gas turbine plant (CCGT). 15 gas turbines (GT), divided into five blocks, each with 3 type GE7FA gas turbines, were installed and put into operation in 2008.

The plant is to be expanded into a CCGT plant without interrupting operation. Installation will be made in a 3+3+1 configuration, which means that each of the five blocks will be expanded by three waste heat boilers, running together to one steam turbine per block. In addition, the entire plant will be expanded by a sixth block with the same design. The total installed capacity will be approx 3,800 MW.

Gas Turbine power plants in saudi ArabiaIn addition to support for utility companies, specifically on the inves-tor’s or owner’s part, Lahmeyer International also carries out engineer-ing services for power plant suppliers and contractors.

Over the last two years, Lahmeyer was charged with the overall planning of 10 crude oil-fired gas turbine systems at four different sites. This includes the Hail 2 power plant, expanded by four Siemens SGT6 PAC 2000E gas turbines with an installed capacity of 67 MW each, taking into account the local environmental conditions. In the meantime, the first two gas turbines started operation prior to the contrac-tually agreed deadline. The overall electrical capacity of all plants amounts to nearly 800 MW.

Consultancy for a Combined power and desalination plantLahmeyer International is active as technical consultant within a consortium comprising of a financial advisor and a legal office on behalf of the client, Partnership Technical Bureau (PTB), for the development of Kuwait’s first combined power and desalination plant financed by project funding (IWPP = Independent Water & Power Plant).

The services include: • Project management• Conceptual design• Feasibility study• Preparation of tender documents• Evaluation of proposals• Contract negotiations• Preparation of contract documents

The plant is powered by natural gas and has an installed capacity of slightly more than 1,500 MWel and 102 MIGD (Million Imperial Gallons per Day) of fresh water production.

The generated electricity is fed into the 400 kV grid, the produced drinking water is fed into the national water network, both operated by the Ministry for Electricity and Water (MEW).

Renewable EnergyNour one photovoltaic power plantThe Abu Dhabi Future Energy Company Masdar is in the process of developing a photovoltaic plant with 300 MW of installed capacity at the Al Ain site. For the first step, Lahmeyer International developed the overall design concept for the 300 MW facility. Afterwards, Lahmeyer aided in the project develop-ment for the first phase with a capacity of 100 MW in the beginning of 2011.

The conceptual design was prepared for this free field power plant using modules without tracking systems. According to this design, annual energetic yields of up to 175 to 220 GWh could be achieved. This design was followed by a PQ and tendering phase, evaluation of the proposals sub-mitted, and recommendations on contract award.

The special characteristic of this power plant under desert conditions – the larg-est of its kind currently planned in the region – is the application of different modules. The reason for this lies in the fact that the photovoltaic modules are manufactured directly by the client, and therefore it would like to use its own modules for part of the power plant.

solar-Thermal power plant project in EgyptAfter Egypt began operation of one of the world’s three Integrated Solar Combined Cycle plants in 2011, the Egyptian energy ministry currently intends to develop an even larger solar-thermal power plant project with an installed capacity of approx. 100 MW at the Kom Ombo site on the Nile River. Various development banks, foremost KfW, are to finance the project.

In 2011, Lahmeyer International was assigned with the feasibility study. In the layout study, various alternatives were conceptually designed and calculated according to technical and economic aspects. Up to now, the combination of a parabolic trough system with a 6-8 hours salt storage turned out to be the most appropriate option for implementation.

Wind projects in EgyptUtilising the extensive wind resource plays a prominent role in the Egyptian energy strategy. For this reason, Lahmeyer International has given advisory as Owner’s Engineer to the New and Renewable Energy Authority (NREA) in the Egyptian wind sector for over eight years.

Initially, the KfW-financed Zafarana IV wind farm with an installed capacity of 80 MW and 94 turbines was planned, tendered, awarded, construct-ed and operated – this was all super-vised by Lahmeyer over a five year period.

Moreover, in 2010, Lahmeyer’s wind team prepared a comprehensive environmental impact study with the objective to assess sites for a total of 1,000 MW of wind farms in Egypt. This includes, among others, wide-ranging ornithological studies. Within the scope of a feasibility study and by accompanying a vast measuring campaign, an intensified search for an optimum site for a 200 MW wind farm has taken place since 2010, considering an area of 4,200 km2.

2012’s most recent mission is the appointment as Owner‘s Engineer on behalf of NREA for tendering, award, and site supervision of a 220 MW wind farm in the Gulf region of El Zayt. The Japanese Development Bank JICA is taking over the project financing.

power GridsQatarLahmeyer was awarded its first contract in Qatar in the beginning of 2007 by the local power utility KAHRAMAA. The contract comprised the planning and site supervision of a 220 kV submarine cable link through the Doha Bay (approx. 7 km length) in order to create an alternative and shorter connection between the “old“ and the “new“ Doha in the so-called “West Bay”.

In 2008, Lahmeyer received another contract for site supervision of part of the so-called “Phase-8“ grid expansion with several 220 or 132/66/11 kV stations as well as a 400/220 kV grid station. Due to the overall project size, the client partitioned the work among three consultants.

Moving forward, Lahmeyer obtained a major contract from Qatar at the end of 2011; it includes a 60 % share of the overall project focusing on site supervision - the remaining 40 % were portioned among two other consult-ants. A total of five general contractors carry out construction works.

Lahmeyer consults on the construction of three 66 kV and four 220 kV grid stations as well as the expansion or rehabilitation of three 66 kV, four 132 kV and three 220 kV grid stations. Also the associate sixteen cable connections between the grid stations on the 66 kV, 132 kV and 220 kV grid level fall within the scope of services. Moreover, Lahmeyer is responsible for the super-vision of fire protection measures as well as for Health, Safety and Environ-ment (HSE) within the overall project.

Abu dhabiSince 1973, Lahmeyer has been active with numerous local utility in the Gulf Region. Thus, Lahmeyer has made a significant contribution to the develop-ment of the transmission and distribu-tion network in the Emirate of Abu Dhabi - from planning and tendering though final commissioning.

Using advice given by Lahmeyer’s specialists, a 400 kV level transmission line was introduced in the early 90’s, which to this day is continuing to grow. The grid calculations performed by Lahmeyer have also shown, that a considerable amount of reactive power compensation was necessary, which also resulted from varying loads during summer and wintertime (winter load approx. 30 % below summer load). Thus, Lahmeyer recommended placing phase shifters as well as Static Var Compensation (SVC) Systems in the grid.

Currently, Lahmeyer’s activities are mainly concentrating on the 400 kV grid including the associate 400 kV grid stations and their integration into the network via 400 kV overhead lines or 400 kV XLPE high-voltage cables having one of the world’s longest routes of more than 20 km between Mahawi and Sas al Nakheel.

Among the projects currently attended are the following (always including the respective network integration):• 400/132 kV Ajman Grid Station• 400/132 kV Bahia Grid Station• 400/132 kV Mahawi Grid Station• 400 kV Ruwais Grid Station• 400 kV Shamka Grid Station• 5x 132/11 kV Substations in Abu Dhabi

outlookIn the coming years, the Near and Middle Eastern region will be one of the fastest growing economic regions in the world. In the future, solar and wind energy projects are steadily increasing in importance for domestic energy supply and also for export to Europe (keyword “Desertec”), and thus will combine with the extensive oil and gas resources and their use as an energy source for the global economy.

Lahmeyer has developed and main-tained customer relationships in this region for decades. The technical planning and implementation competence for various modern power plant and grid technologies

that Lahmeyer possesses is key for successful project work in the region in order to efficiently use the existing energy resources, and thus to contribute to the region’s growth. Dr. Andreas Wiese

Arab-German Energy Forum in Berlin, Germany

The sharp rise in electricity demand in the Arab world was the main issue of the 3rd Arab-German Energy Forum taking place in Berlin in October 2012. About 300 experts and high-ranking decision-makers took up the invitation of the Ghorfa Arab-German Chamber of Com-merce and Industry e.V. They gained a comprehensive overview on the latest developments of the Arab energy industry and the business opportunities resulting thereof.

In order to cover the increased demand for energy, Lahmeyer International focusses on improv-ing energy capacities in the Arab region. For this reason, Lahmeyer’s competence was also called for following discussions and the carrying out of the two-day congress. Dr. Andreas Wiese (see image), Executive Director of the Energy Division, and Mr. Thomas Kraneis, Executive Director for Customer Relationship Manage-ment, brought Lahmeyer’s know-how into several panel discussions.

ENERGY

The Republic of Cape Verde, an island state, is located 570 km off the West-African coast in the Central Atlantic Ocean. Ten islands, among them the largest named Santiago, belong to this archipelago. About 90 percent of electricity is generated by Diesel power plants, which demands the import of expensive fuel.

Due to the steeply rising demand for electric power in a tight market, in recent years supply of energy is more frequently subject to cuts and rationing in the island’s capital, Praia. Moreover, caused by the strong increase in fuel prices, electricity has become a luxury good which fewer people are able to afford.

Necessary ModernisationIn order to improve this situation, the government decided to expand the Palmarejo Diesel power plant by 22.6 MW and also to modernize the island’s electricity grid. In addition, photovoltaic plants and wind farms will be devel-oped to reduce fuel prices. The government’s plans further include the modernisation of the existing heavy oil infrastructure to obtain less expensive heavy oil with a higher viscosity (up to 380 centistokes).

ELECTRA, a utility active in several sectors, is responsible for the island’s electricity supply as well as for Praia’s water supply by desalination using reverse osmosis. The utility also operates three Diesel power plants (35.6 MW), wind farms with 9.3 MW of installed capacity and photovoltaic

Electricity consumption in santiago, the capital of Cape Verde, is steadily on the rise. For this reason, the island state initiated a series of energy projects. The objective is to optimise and expand both the electricity and distribution network and the existing diesel power plants and renewable energy systems. on behalf of the government of Cape Verde, the Joint Venture lahmeyer international / soFRECo undertook engineering services for the expansion of the palmarejo diesel power plant and for modernisation of the electricity network.

plants with a capacity of 4.2 MW in Praia. In mid-2012, the load was between 17 to 32 MW. At sunny and windy weekends, the share of renewa-ble energy periodically covered 50 percent of the demand. The entire electricity system and the load distribution are controlled by the Palmarejo Diesel power plant.

Comprehensive MeasuresThe Palmarejo Diesel power plant is located onshore outside Praia. Its former overall installed capacity of 25.8 MW was produced by four medi-um-speed Diesel aggregates operated by heavy fuel oil.

To finance the power plant expansion and the modernization of the electrici-ty grid, the government of the Republic of Cape Verde received a loan from the African Development Bank (AfDB) and the Japanese Bank for International Cooperation (JBIC).

The new power plant expansion consists of a new powerhouse with two 11.3 MW medium-speed type Wärtsilä 46 Diesel aggregates. A fuel-processing building, an additional heavy oil storage tank with a capacity of 1,500 m3, and a new tank farm for

fuel, lubricating oil, water, and sludge, make up the new complex. The existing medium-voltage switch room was expanded in order to accommodate the new substations. Closed-circuit water-air radiator coolers dissipate the heat produced by the Diesel engines to the ambient air. The power plant’s gas and liquid emissions are in accordance with World Bank guidelines.

Rapid implementationThe local government together with ELECTRA prepared the preliminary studies and the tender documents. Lahmeyer commenced in March 2009 with evaluation of the EPC-proposals. Contract negotiations took place in August and October 2009, led by the government and ELECTRA and supported by Lahmeyer.

In February 2010, the Finnish engine manufacturer and general contractor Wärtsilä received the EPC contract. Lahmeyer verified and approved the detailed design. During the construc-tion phase, Lahmeyer specialists visited the Praia site several times in order to oversee the contractual work and to discuss and clarify any devia-tions and deficiencies detected with the client.

After completing the works, followed by the successful advance commis-sioning, the power plant was put into operation in mid-August 2012.Samuel Karres

The Seychelles, also called ‘’Pearl of the Indian Ocean’’, are one of the world’s most beautiful archipelagos. They are located four degrees south of the equator in the western part of the Indian Ocean. A peak load of electrical power of up to 55 MW is achieved on the islands. The vast majority of this demand is currently met by state-owned oil-fuelled power stations.

In 2009, the Seychelles Government decided to develop the utilisation of renewable energies on the islands. In March 2012, first wind resource assess-ments were completed and an initial design has been prepared for a first wind park. The foundation stone for the installation of eight wind turbine generators – five at Ile de Romainville and three at Ile du Port – was laid.

Energy which respects the Environment The wind farm project will reduce the annual fuel consumption for energy production by about two million litres – which means cost saving of around Euros 1.3 million. Each kilowatt hour produced by this wind farm will also prevent the release of almost 800 grams of greenhouse gases giving a total annual reduction of more than 6 million kg of greenhouse gas emis-sions into the atmosphere.

Within the scope of the wind power project, Lahmeyer International has in-vestigated the impact of the new wind farm on the existing electrical grid. The study’s objective was to analyse to what extent the stable operation of the new and existing generation systems and the reliable transmission

The first major wind farm of the seychelles islands is in the process of preparation. it should cov-er more than one tenth of electricity demands of the main island and will cut down on fossil fuel imports and reduce greenhouse gas emissions. lahmeyer international has successfully conducted a comprehensive grid impact study for the wind farm’s connection to the existing infrastructure.

of wind power within the main island could be guaranteed.

Extensive analyses of power flows, short circuit, power quality and transient stability were conducted by the experts of Lahmeyer International with the aid of the power system anal-ysis software DIgSILENT PowerFactory.

It is worth noting that wind genera-tion has a number of characteristics, especially with regard to the dynamic behaviour which are substantially different from those of conventional power generation stations. Addition-ally, in hybrid wind/Diesel systems, power quality and transient phenom-ena represented crucial elements for the grid impact study.

studies optimising plants The required mathematical model of the power system was prepared by the Lahmeyer team for a complete representation of the 33 kV and 11 kV electrical systems of the Seychelles including the extension projects for the wind farm connection.

The electro-mechanical behaviour of the power generator systems was realistically simulated through composite models of Diesel and wind turbine generators, control and protec-tion systems.

In August 2012 Lahmeyer completed the study. It served to verify the suita-bility of the wind farm connection and the appropriate levels of wind power penetration in various multi-operat-ing scenarios. The study also resulted in an optimal design of the wind farm equipment and grid connection schemes.

In addition to the grid impact study, setting calculations for the selective triggering of grid protection (adjusta-ble parameters) were carried out.

The full study, submitted to the client in October 2012, defines the setting criteria and parameters for a safe and effective operation of the wind farm during disturbance events, such as short circuits.Luca Pizzimbone

To a large extent, Cyprus‘s power generation is largely dependent on fossil fuels and is also limited by having only a small number of power plants.

More than 50 percent of the electricity demand for the entire country origi- nates from one single power plant, Vasilikos (VPS), located about 25 km east of Limassol on the southern coast of Cyprus. This power plant and the overall power generation and distribu-tion in Cyprus are operated by the owner, the State Electricity Authority of Cyprus (EAC). To meet the country’s rising electricity demand, the EAC has continually increased the installed power plant capacity.

High-Capacity power plantThe Vasilikos power plant plays a key role in Cyprus. The overall capacity of all five units is 860 MW. The plant’s first combined-cycle power plant (CCPP) with a capacity of 220 MW was connected to the grid in July 2006.

Another CCPP unit – expansion phase IV / unit 5 – which Lahmeyer took over consultancy services on behalf of the EAC, from the tendering through construction, commissioning, and guarantee period, is also a 220 MW combined-cycle block.

Unit 5 comprises two type GE Frame 6FA+e gas turbines, two horizontal waste heat boilers produced by NEM (two pressure levels, without super-heating) and an Alstom MT steam turbine. The plant operates with an overall efficiency of about 50 percent. Currently, all other power plant units in operation are fired with Diesel oil.

Conversion to gas will be undertaken at a later stage.

Explosion delays CommissioningInitially, unit 5 was planned to be commercially commissioned by the end of 2011. The gas turbines as well as all auxiliary plants (BoP, Balance-of-Plant) were completed in July 2011 and handed over to EAC.

Shortly afterwards, on 11 July 2011, a devastating explosion on Evangelos Florakis marine military basis dam-aged the whole power plant. This catastrophic event caused the death of 13 people and 65 personal injuries.

The plant failure had a significant impact on the power supply through-out the whole island. The explosion paralysed all construction activities, and brought the work for the new unit 5 to a standstill.

successful ReconstructionUnder the supervision of EAC and Lahmeyer, reconstruction work for unit 5 started, whereby Lahmeyer - within the processing of insurance claims -

was entrusted with additional investigations and cost estimates.

A significant proportion of the reconstruction work was performed by the EPC (Engineering, Procurement, Construction) contractor - a consorti-um with J&P-AVAX from Athens/Greece, Hitachi Power Europe (HPE) from Germany and General Electric, who supplied the original gas turbine plant.

In November 2012, one year after the terrible accident and after twelve months of hard work, unit 5 was handed over to EAC for commercial operation.

Lahmeyer would like to take this opportunity to wish EAC a successful reconstruction and commissioning of blocks 4 in early 2013 and all of the remaining blocks by the end of 2013.Richard Wilhelm

Vasilikos power plant is the backbone of power generation in Cyprus as it supplies more than 50 percent of the country’s electrical energy. in summer 2011, it was badly damaged by a massive explo-sion on a neighbouring property. The catastrophic event killed 13 people, shut down in the facility, and put unit 5 behind schedule. With support from lahmeyer, the new unit was started up again in autumn 2012.

Mobility by Real EstateA model project in Frankfurt Rhein-Main connects living and driving in an environmentally sound manner. This is part of the corporate initiative “Mobility by Real Estate”, in which lahmeyer Rhein-Main is involved.

The project scope comprises eight private homes in the Quellenpark district of Bad Vilbel and for the first time a multi-family house in the Riedberg district of Frankfurt. They are constructed and powered with electro-mobility under actual living and market conditions according to the plus standard for energy-efficient houses. Construction of a multi-family house in this standard is a nationwide premiere in Germany.

After the development of low-energy houses and passive houses, the plus standard for energy-efficient houses advances the energy-optimisation of buildings, by utilising regenerative energy production from building systems themselves. This energy can now be fed into the grid or, which is the concept of this model project, be directly used in the form of electro-mobility. The house becomes the charging station for one’s own

electro-mobility. The innovative concept of this symbiosis will be evaluated and optimised in practice.

Visionaries Create solutions for the FutureThe idea of the corporate initiative emerged from discussions on intelli-gent connections of real estate and mobility at the sites of the Federal Ministry of Transport, Building and Urban Affairs (BMVBS) in Berlin. It was inspired by the state secretary, Mr. Rainer Bomba, whose research initiative “Zukunft BAU” (“Future Building”)“ has the ambitious aim that – starting in 2019 – newly constructed buildings should generally operate in a climate-neutral manner.

Together with the city councillor of Bad Vilbel, Mr. Rüdiger Wiechers, Dipl.-Ing. German Halcour, Managing Director of Lahmeyer Rhein-Main, initiated this project, fully convinced

that it will offer future opportunities and possibilities. The corporate group Nassauische Heimstätte/Wohnstadt, the Bien-Zenker AG and the Adam Opel AG became part of the initiative. They all support the slogan “Mobility by Real Estate”.

The Federal Ministry for Building Affairs accompanies and supports the initiative and thus additional players from science, industry and participat-ing municipalities could be recruited to engage in the undertaking. With their entrepreneurial courage, their pioneering spirit and their farsighted-ness, the initiative members apply their professional know-how in sustainable solutions in times of change.www.immobilien-machen-mobil.de

New Star in Berlin City SkylineBerlin is more attractive than almost any other European metropolis. As an increasing number of people and companies see their future here keeps the city growing. With the Königstadt Carree office and hotel project Berlin‘s Alexanderplatz has gained another attraction. in its role as project manager, lahmeyer Berlin is involved in the realisation of the construction project.

The German investor bauart Beteili-gungs GmbH & Co. Mollstraßen KG of Berlin has provided funding at the amount of around Euro 100 mill. to implement the high-rise project. In their function as project corporation, they developed, built and leased the property located at Moll Street/Otto Braun Street. This is a building complex with a useable area of 32,313 m2 on 22 floors and an 85 m high office tower which counts among the highest residential towers in Berlin, visible from a considerable distance.Today, it is home to renowned companies such as Mercedes-Benz with its service centre, Google, and one Etap Hotel belonging to the Accor Group. Here, Accor established for the first time the new room design for the Etap brand.

“Due to the project size, it was foreseen from the outset to entrust a reputable company with the overall project management and consulting services“, says the managing director of bauart, Dipl.-Ing. Manfred Herrmann. “After having launched an invitation to tenders and the outcome of numerous talks, we have decided to award Lahmeyer Berlin the essential tasks of project management“.

The most important criterion for deciding on Lahmeyer Berlin was that they could ensure the integration of specialists for structural planning and technical building equipment.

With more than ten years‘ experience in the field of project management,

controlling and quality management as well as budgeting and monitoring Lahmeyer’s extensive requirement profile was deemed suitable to take the lead with management.

Challenging Tasks reliably fulfilled The Lahmeyer team performed the multi-faceted job adhering to a strict time schedule.

Apart from project structure planning the Lahmeyer experts were responsi-ble for individual contract awards, construction supervision and time scheduling. In addition, the engineers coordinated all parties involved in the project, checked the account status of all technical disciplines, and took over monitoring for the prevention of disputes, especially for the assessment of performances and amendments.

“Lahmeyer made a significant contribution to contract completion within a tight time schedule, not providing any reserves, and on adherence to the project budget”, Manfred Herrmann stated. “Cooperation with Lahmeyer Berlin was always characterised by a trusting and team-oriented relationship. Our project benefited from the professional competence of the personnel engaged, becoming particularly apparent by the mastery of complex site processes, combined with a purposeful and proactive working style, a great deal of perseverance, and a high degree of assertiveness.”Dirk Bormann

BUILDING & TRANSPORTATIONGERMANY

Train by Train – Rapid Transit Line to be extendedin order to help the region south of Wolfratshausen be better linked to the Bavarian capital and metropolitan area of Munich, the rapid transit line s7 is to be extended to Geretsried. lahmeyer München is leading preparation of the planning for dB projektBau.

Since 2007, the project is in the planning stage and is currently undergoing approval. This is the prerequisite for ensuring that the 24,000 inhabitants of the strongly growing town of Geretsried can reach Munich much faster by using public transport systems. The administrative district of Bad Tölz-Wolfratshausen will also benefit from the planned extension of the S7 line. The construction of a new single-track section from Wolfrats-hausen to Geretsried is planned.

With this measure, the Free State of Bavaria will fulfil the objectives in the field of transport imposed by the Bavarian regional development programme. This programme aims at working towards favourable traffic connections – above all by using public

transport – taking into account the environmental development. Rural areas should be better accessed by urban transport systems.

Object planning for rail and road trans-port facilities as well as engineering structures belong to the tasks of Lahmeyer München. The engineers from Munich also undertake assign-ments in the fields of structural planning, surveying, geotechnical and environmental planning; noise and vibration as well as fire protection expertises complete their range of services within the overall planning. This includes coordination and integra-tion of specialist planning of rail technical equipment, such as control and safety systems as well as traction power and telecommunication systems.

Future Track RouteThe project starts at the final station of the 5507 line Munich–Solln–Wolf-ratshausen which currently is Wolf-ratshausen. Starting from here, the existing railway line will be extended and continued as about nine km long new line passing Gelting Ort, Gelting Industriegebiet, Buchberg, Geretsried Nord and Mitte (= Geretsried Garten-berg) up to Geretsried Süd. New stations will be constructed in the suburbs of Gelting and Geretsried Mitte. The new final station is planned to be located between Geretsried Süd and Stein suburb.

Having nine railway overpasses and three road overpasses new railway line will be crossed in a collision-free way.Konrad Daxenberger
