Following the conclusion of the three-day production and operational testing period, Abengoa Solar has begun commercial operation of the PS20 solar power tower plant, located at the Solucar Platform, near Seville, Spain. With a power capacity of 20 MW, the facility is the world's largest solar power tower plant, according to Abengoa.
PS20 is the world's second power tower plant in commercial use. The plant features numerous technological improvements over PS10, the world's first commercial power tower.
These enhancements, developed by Abengoa Solar, include a higher-efficiency receiver, various improvements in the control and operational systems, and a better thermal energy storage system.
PS20 consists of a solar field made up of 1,255 mirrored heliostats designed by Abengoa Solar. Each heliostat, with a surface area of 1,291 square feet, reflects the solar radiation it receives onto the receiver, located on the top of a 531 feet-high tower, producing steam that is converted into electricity generation by a turbine. Plant construction was carried out by Abener.
