Europe's first commercial concentrating PS10 solar power tower is operating near the sunny southern Spanish city of Seville. The 11 megawatt solar power tower produces electricity with 624 large movable mirrors called heliostats.[1] The mirrors were delivered by Abengoa, the solar receiver was designed and built by Tecnical-Tecnicas Reunidas, a Spanish Engineering Company; and the Solar Tower was designed and built by ALTAC [2], another Spanish Engineering and Construction Company.
Each of the mirrors has a surface measuring 120 square meters (1,292 square feet) that concentrates the Sun's rays to the top of a 115 meter (377 foot) high, 35-story tower where a solar receiver and a steam turbine are located. The turbine drives a generator, producing electricity.[1] This power is three times more expensive than power from conventional sources, but prices will fall, as they have with wind power, as the technologies develop.
