Europe's first commercial solar plant, situated in Sanlucar la Mayor, 25 km west of Seville, was inaugurated in March 2008. The 11 MW plant, known as PS10, is the first tower technology solar thermoelectric power plant used for commercial purposes in the world and generates electricity to power 6,000 homes. 624 heliostats, or movable mirrors, concentrate solar radiation onto a receiver located on a 115 m high tower. Water is turned into steam which is then blasted into turbines to generate power. The PS10 plant is part of the Sanlucar la Mayor Solar Platform which, when completed in 2013, will provide enough energy to power some 180,000 homes, or a city the size of Seville.
