Solar power: powerful weapon to reduce greenhouse gas (GHGs).
IEA (2008) projected that 11% (4754TWh) of the global electricity demand until 2050 could be provided from solar energy in order to reduce 50% of GHG emissions.
Besides photovoltaic panels, CSP plants are estimated to produce about 46% (2200 TWh) of the projected amount of solar power annually.
From 1999 to 2001, the Global Environment Facility (GEF), the World Bank and Eskom Enterprises, jointly financed a study entitled “CSP-Africa".
IEA (2008) recognize that the African continent has the greatest potential for using solar PV and CSP.
The GEF has supported the development and deployment of technologies with low GHG emissions that were not yet commercial, but showed promise of becoming so in the future (Diarra et al, 2001).
South Africa is a substantial emitter of greenhouse gases
89% of carbon emissions from energy related activities in Southern Africa (Energy research centre, 2007).
The country’s power generation is heavily dependent on coal. 95% of national power demand is supplied by the predominantly coal-based utility Eskom.

Electricity demand increased at a fast speed of 8.2% annually from 2000 to 2006.
Morocco is heavily relying on energy imports with 95% of its energy need, dominantly from fossil fuels source.
The GHG emissions provided of fossil fuel have grown at an average rate of 6.3% annually from 2000.
In November 2009, the government initiated a Moroccan Solar Plan aiming at a 42% renewable energy target by 2020 and a 2000 MW capacity for solar power including CSP by 2020.
Total cost: US$ 114.36 million
Co-financed by equity from the plant owner, and the preferential loan from the AfDB.

Egypt ranks the 11th fastest growing GHG emission in the world.
Its CO2 emission increases of 7% annually since 2000.
The CSP project was designed as Integrated Solar Combined-Cycle with a capacity of 150 MW including 20 MW from solar.
Project cost: US$147 million
The local cost is estimated to be 20% of the total investment.
GEF grant shares USD 49.8 million of the total cost.

Entering the GEF work program: Morocco (1999), Egypt (2004).
Morocco and Egypt projects contribute to Operational Program 7’s goal of reducing long-term costs of low GHG emitting energy technologies.
The South Africa project evaluates economic, environmental, and social aspects of the STE technology. It benefits the Egypt and Morocco projects in terms of identifying impediments to sustainable deployment.
Different from the South Africa project, the Egypt and Morocco projects looked at the market and cost reduction potentials of STE technologies.
a.) (2/2)Capacity building
Capacity restriction and a lack of industrial infrastructure are big hurdles for new technology.
Building broad-scale capacity of key stakeholders is critical to project design and implementation of new technology penetration in developing countries.
Stakeholders can then be provided with knowledge of the new technology for risk analysis, project implementation and monitoring.
Supports and participation from stakeholders and communities can greatly catalyze market entry of CSP technologies.
Table 1: Capacity building issues and the GEF projects’ contributions to addressing them
The lack of CSP technology application from developed countries has impaired credibility of the technology in developing countries, and the lack of knowledge and expertise in host countries makes it even harder to implement.
Without participation and advocates of new technology, the CSP technology transfer can be difficult.
Table 4: Technology transfer issues and the GEF projects’ contributions to addressing them
The GEF has implemented energy policies and/or energy efficiency policies in the three countries and encourages solar power to meet the targets set by each government.
Table 2: Policy issues and the GEF projects’ contributions to addressing them
There is strong need for national or regional loan guaranteed programs and long-term financing mechanisms to ensure sustainable deployment of CSP.
Cooperation with bilateral and/or multilateral financial mechanisms, such as Clean Development Mechanism, diversifies the financial risk from single institutes and reduces the inherent financial risk of new technologies.
The GEF is able to mitigate high financial risks through mobilizing private sector participation, investigating alternative solutions and costs, and leveraging public and private investment.
