The PS20 solar energy plant (PS20) solar energy plant is a solar thermal energy plant in Sanlucar la Mayor near Seville in Andalusia, Spain. It was the worlds most powerful solar power tower till the Ivanpah Solar Power Facility in California became functional in 2014. The 20 megawatt (MW) solar energy tower produces electrical power with large movable mirrors called heliostats.
Building and construction of PS20 was begun in 2006 and it began operation in 2009. It features a number of substantial technological enhancements over the earlier PS10. These consist of a receiver with higher effectiveness, numerous improvements in the control and functional systems, and a much better thermal energy storage system.
” PS20 includes a solar field of 1,255 mirrored heliostats developed by Abengoa Solar. Each heliostat, with an area of 120 m2 (1,300 sq ft), shows the solar radiation it receives onto the receiver, situated on the top of a 165-metre-high (541 feet) tower, producing steam which is transformed into electrical power by a turbine generator.”
” The staying power plants will be developed over the next few years. They will include low- and high-concentration photovoltaic, tower thermoelectric, parabolic-trough collector and Stirling meal plants. Abengoa Solars parabolic trough plants, Solnova 1, 3 and 4, which can produce 150 MW of power, are under building and construction at the Solar Platform.”
Arising from cooperation between Ciemat, the IDEA, and the University of Seville, the entire plant is to be finished by 2013, when it will produce approximately 300 MW– energy for around 180,000 homes, comparable to the requirements of the city of Seville. PS20 produces about 48,000 megawatt-hours (MW · h )per year, for which it gets EUR271 (US$ 360) per MW · h under its power purchase arrangement.
