SWH in Context

Motivation for SWH Implementation• Load shedding• Electricity crisisy• DSM• In order to provide funding for required generation capacity growth, NERSA approved

Eskom’s application for annual electricity tariff hikes of 25% for the 2012-2014 period• However until sufficient generation capacity can be commissioned security of supply isHowever, until sufficient generation capacity can be commissioned, security of supply is

still expected to be threatened for the 2010 to 2016 period• Supply gap compounded by the delay in the completion of Medupi and Kusile• Efficient water heating is identified as a prime mechanism for demand side management• Other drivers for the project include job creation skills development reduction of carbon

Carbon Benefits

18% of total national electricity supply is allocated toward the heating of water18% of total national electricity supply is allocated toward the heating of water

The heating of water consumes as much as 40% of domestic electricity usage

Efficient water heating thus provides both environmental and economic benefits

For every 1kWh of energy produced by a coal power station 0 966kg of carbon dioxide is produced For every 1kWh of energy produced by a coal power station, 0.966kg of carbon dioxide is produced

The energy saving of a single SWH will result in an annual average saving of over 2,400 kWh

This amounts to a CO2 saving of 2,320 kg of carbon dioxide per year, per SWH

If one million solar water heaters were installed in South Africa this could alleviate 578GWh of electricity from the grid If one million solar water heaters were installed in South Africa, this could alleviate 578GWh of electricity from the grid

annually, the equivalent output of a 2,000MW power station

The avoided resources depletion externality results in the conservation of 3,1 million litres of water and 1.2 million tons of coal

The carbon emissions offset possible for the installation of one million solar water heaters would save 2,320 billion tons of carbonp ,

Global Policy Mechanisms for SWH

Rationale for SWHPolicy Mechanisms for SWH

Globally, different policy methods have beenused to foster the deployment of SWH

Primary policy mechanisms include:

Rationale for SWH

Solar water heaters globally have gained interest and popularity as a means to:

Reduce reliance on national energy supply Collector-area-based subsidies

Performance-based subsidies

Tax credits

Tax deduction

Take strain off peak-time power loads

Mitigate carbon emissions

Tax deduction

Mandatory legislation

International best practice has shown that

• National support needed due to high initial cost

often a combination of these policies providethe best framework with which to facilitatethe efficient deployment of SWH

21 countries currently have some policy

• International experience has shown that enabling policies, information, access to financing, supply side strengthening and sustainable institutional

measure in place to upscale the use of SWH support are needed in this regard

The Global Solar Water Heater Market

More than 70 million households globally now have solar water heater systems installed (2010)

China is the world’s largest user of SWH Total installed capacity of SWH is estimated at the equivalent of 154GW, more than 65 per cent of global capacity

Countries with high per capita uptake, such as Cyprus, Israel, Spain and Austria, all have policy mechanisms in placeto support this uptaketo suppo t t s upta e

Cyprus’ legislation requiring SWH installation in all new buildings, has resulted in 92% of residential buildings being equipped with SWH

Spain, the world’s fourth largest SWH manufacturer, has seen significant growth since 2000, with a mandatoryordinance by the City of Barcelona to install SWH in all new buildingsordinance by the City of Barcelona to install SWH in all new buildings

Following the success of Barcelona’s municipal framework, over 60 Spanish cities have followed suit

Water heated by solar energy generally requires solar thermal collectors, a water storage tank, interconnecting pipes and a fluid system to move the heat from the collector to the tank

This thermodynamic approach differs from photovoltaic (PV) technology in that sunlight directly heats the water, as

• Came into effect in August 2000

• The ordinance requires all new buildings, those undergoing a complete

Installed Capacity 173,340 units (2010)

The ordinance requires all new buildings, those undergoing a completerefurbishment or changing their function, to have SWH account for apercentage of their hot water usage

• This applies to residential, commercial and industrial buildings

and to expand the building scope by decreasing what would be excluded

International Benchmarking

City of Barcelona

• As the Barcelona model unfolded, it was noted that initially SWH were ordered by construction companies that had little or nomotivation to choose higher quality products than what was strictly required by the wording of the regulation; once thesebuildings were solved or rented, these companies did not benefit from the energy savings

• Their main goal was to keep down the investment costs, treating SWH like any other building component

• A key success factor of the Barcelona Ordinance was the lengthy consultation process and pre-mortem, which entailed athorough debate involving: constructors; building administrators; architects; engineers; installers; consumers and tenants; aswell as the local, regional and national energy agency and the public bodies responsible for housing, urban planning,protection of architectonic heritage and environment

• This pre-mortem entailed flexibility and a debate that facilitated the correct implementation of the ordinance

• In less than five years, Barcelona multiplied its SWH use per capita by twenty times• The market was able to rise up to meet demand, due to the time lag between building plan passed and actual installation

• A large number of installers architects and building engineers were trained and gained practical experience with SWH technology• A large number of installers, architects and building engineers were trained and gained practical experience with SWH technology

• The construction companies became accustomed to include SWH from the earliest stage of planning, thus reducing the time and costs needed tointegrate it at a later point

• Citizens and potential users were informed about solar

Th B l d l d d f l it h b d i 60 S i h iti i l di M d id d S ill• The Barcelona model was deemed so successful it has been used in over 60 Spanish cities, including Madrid and Sevilla, aswell as internationally in Sao Paulo and Rome

Quotes from the Barcelona solar experience

• “The introduction of this regulation gave rise to numerous debates and protests. In particular, it was necessary to win over the various actors in theconstruction sector (architects, builders, investors, etc.). The most difficult group were the investors, who were not entirely convinced of the wisdom ofsuch a choice, nor of the reliability of the technology. “ World Energy Council

• “They were also concerned about the possible impact of the extra cost of solar installations on the construction market, and especially any extra timethat might be needed to obtain equipment that was not readily available. Finally a moratorium of several months was allowed before the regulation wasenforced to give everyone time to adjust to the new requirements. This is an example of a regulatory decision applicable across the board and whichwas drawn up with the general agreement of all the stakeholders.” World Energy Council

• “The extra investment incurred by the Ordinance is estimated to be 0.5%-1% in building work and materials (Stirzaker P., 2004). This extra-investmentmay be financed by interest-free credit arrangements available from IDEA and the public credit institute, Instituto de Crédito Oficial (ICO). The creditbacks up to 70% of total investment (Ibid.)” Barcelona Energy Agency

• “Even with such financing arrangements, reaching a consensus with all the stakeholders involved in the construction sector was essential to thesuccess of the ordinance. Property developers, construction companies, architecture colleges and installation contractors have all been closelyassociated to the construction and implementation of the regulation. Nevertheless, a 18-month moratorium has been introduced for all the sectors top g ,prepare for the new regulation and for installers to gain statutory certification. In parallel, the standard certification of solar systems and installation hasbeen developed in order to prevent the installation of low quality equipment as a result of the ordinance. The City of Barcelona has also implemented abroad communication program and organised periodic round tables in order to promote and facilitate the acceptance of the Ordinance.” BarcelonaEnergy Agency
