The PS10 Solar Power Plant is a commercial concentrating solar power station near Seville in Andalusia, Spain. It consists of 624 movable heliostat mirrors — each with a surface area of 1,300 square feet (120 square m) — that concentrate the sun’s rays to the top of a 377-foot (115-m) high tower containing a solar receiver and steam turbine. PS10 produces about 23,400 megawatt-hours of electricity per year.
