Spanish renewable energy firm Sener and Abu Dhabi's clean-energy initiative, Masdar, announced a joint venture on Wednesday to build several power plants fuelled by the sun.
The newly created firm, Torresol Energy, said it plans to build at least two large concentrating solar power plants a year with a goal of generating 320 megawatts over the next five years and 1,000 megawatts in ten years. A large coal-fired power plant typically can produce hundreds of megawatts of electricity.
One of the designs that the venture intends to use is a solar receiver tower to be built in Abu Dhabi. In a tower construction, mirrors are mounted on the ground to reflect light to the top of a tower, where steam is created to turn an electricity turbine. A handful of other companies, including BrightSource Energy and eSolar, are pursuing a similar tower design.
The new company underscores the surge in investment on solar thermal technologies, which use the sun's heat, rather than photovoltaic panels, to generate electricity.
A number of solar thermal power plants are being proposed for the southwest of the US and Spain, where conditions are best.
Sener already operates three 50-megawatt plants that use parabolic troughs to reflect light and generate heat. They also incorporate molten salt storage to generate electricity when the sun is not shining.
