Moroccan Solar Plan
Morocco has launched one of the world’s largest and most ambitious solar energy plan with investment of USD 9billion. The Moroccan Solar Plan is regarded as a milestone on the country’s path towards a secure and sustainable energy supply. The aim of the plan is to generate 2,000 megawatts (or 2 gigawatts) of solar power by the year 2020 by building mega-scale solar power projects at five location — Laayoune (Sahara), Boujdour (Western Sahara), Tarfaya (south of Agadir), Ain Beni Mathar (center) and Ouarzazate — with modern solar thermal, photovoltaic and concentrated solar power mechanisms.
The first plant, under the Moroccan Solar Plan, will be commissioned in 2014, and the entire project is expected to be complete in 2019. Once completed, the solar project is expected to provide almost one-fifth of Morocco’s annual electricity generation. Morocco, the only African country to have a power cable link to Europe, is also a key player in Mediterranean Solar Plan and Desertec Industrial Initiative. The Desertec Concept aims to build CSP plants to supply renewable energy from MENA region to European countries by using high-voltage direct current (HVDC) transmission lines.
In 2010, the Moroccan Agency for Solar Energy (MASEN), a public-private venture, was set up specifically to implement these projects. Its mandate is to implement the overall project and to coordinate and to supervise other activities related to this initiative. Stakeholders of the Agency include the Hassan II Fund For Economic & Social Development, Energetic Investment Company and the Office National de l’Electricité (ONE). The Solar Plan is backed by Germany, with funding being provided by German Environment Ministry (BMU) and KfW Entwicklungsbank while GIZ is engaged in skills and capacity-building for industry.
Ain Beni Mather Project
The Ain Beni Mather Integrated Solar Thermal Combined Cycle Power Station is one of the most promising solar power projects in Africa. The plant combines solar power and thermal power, and is expected to reach production capacity of 250MW by the end of 2012. African Development Bank, in partnership with the Global Environment Facility and Morocco's National Electric Authority (ONE), is financing approximately two-thirds of the cost of the plant, or about 200 million Euros.
Ain Beni Mather plant, which is now supplying electricity to the Moroccan grid, uses a cutting-edge design, combining a large array of 224 parabolic mirror collectors concentrating sun energy and boosting the steam output needed to produce electricity. This area enjoys abundant sunshine and has enough water to cool the power station and clean the solar mirrors. It is close to both the Maghreb-Europe Gas Pipeline and the high voltage grid that will help to transmit the generated power.
Ouarzazate Solar Complex
The 500MW Phase-One Solar Power Complex at Ouarzazate is the world’s largest solar thermal power plant. To be built with investment of an estimated Euros 2.3 billion, the project is the first one to be implemented under the Moroccan Solar Plan. The Ouarzazate Solar Complex, with a total capacity of 500 MW, will come on-stream in 2015 and produce an estimated output of 1.2 TWh/year to meet local demand. The first phase will be a 160-MW parabolic trough facility while photovoltaic modules and CSP towers will be used in later phases.
The solar energy potential in Jordan is enormous as it lies within the solar belt of the world with average solar radiation ranging between 5 and 7 KWh/m2, which implies a potential of at least 1000GWh per year annually. Solar energy, like other forms of renewable energy, remains underutilized in Jordan. Decentralized photovoltaic units in rural and remote villages are currently used for lighting, water pumping and other social services (1000KW of peak capacity). In addition, about 15% of all households are equipped with solar water heating systems.
Jordan has major plans for increasing the use of solar energy. As per the Energy Master Plan, 30 percent of all households are expected to be equipped with solar water heating system by the year 2020. The Government is hoping to construct the first Concentrated Solar Power (CSP) demonstration project in the short to medium term and is considering Aqaba and the south-eastern region for this purpose. It is also planning to have solar desalination plant. According to the national strategy the planned installed capacity will amount to 300MW – 600MW (CSP, PV and hybrid power plants) by 2020.
One of the most promising potential investments in renewable energy worldwide will be installing more than 250 MW of concentrated solar power (CSP) in Jordan’s Ma’an development zone through different projects developed by the private sector. The upcoming CSP solar power plants in Ma'an would highlight Jordan's strategy of sustainable energy diversification. The Ma'an Development Area enjoys about 320 days of sunshine a year, with a high level of irradiance that allows over 2500 million kWh of primary energy to be harvested annually from each square kilometre. At full capacity, the planned flagship CSP plant could meet some 4% of the Kingdom's electricity needs, reducing the reliance on electricity imports from neighbouring countries. Surplus energy could in turn be sold to Syria, Egypt and Palestine, whose networks are connected to Jordan.
Qawar Energy in partnership with Maan Development Area (MDA) has recently announced the launch of its $400 million Shams Ma’an Project, a 100MW photovoltaic (PV) power plant project to come up at the MDA industrial park in Jordan. The project, being undertaken in partnership with MDA, is spread across a two million m2 area, and expected to be ready in 2012. On completion, it will be the largest PV plant in the world that will position Jordan on the global renewable energy map attracting investments, technologies and knowhow. It aims to utilize approximately 360,000 to 2 million PV/CPV panels and produce around 168 GWh per year
California-based company Ausra has been chosen to supply solar steam boilers to the 100MW JOAN1 concentrated solar thermal power (CSP) project in development in Ma’an. The JOAN1 project is expected to enter operation in 2013 and will be the largest CSP project in the world using direct solar steam generation. JOAN1 will be based on Ausra’s reflector technology to power the plant’s solar steam cycle and generate up to 100 MW of electricity. JOAN1 will use dry cooling to conserve water. Ausra plans to install an advanced manufacturing facility in Jordan in order to supply JOAN1 with its solar steam boilers.
