Spain Overtakes US With World's Biggest Solar Power Station

Spain has opened the world's largest solar power station, meaning that it overtakes the US as the biggest solar generator in the world. The nation's total solar power production is now equivalent to the output of a nuclear power station.

Spain is a world leader in renewable energies and has long been a producer of hydro-electricity (only China and the US have built more dams). It also has a highly developed wind power sector which, like solar power, has received generous government subsidies.

The new La Florida solar plant takes Spain's solar output to 432MW, which compares with the US output of 422MW. The plant, at Alvarado, Badajoz, in the west of the country, is a parabolic trough. With this method of collecting solar energy, sunlight is reflected off a parabolic mirror on to a fluid-filled tube. The heated liquid is then used to heat steam to run the turbines. The mirror rotates during the day to follow the sun's movement. The solar farm covers 550,000 square metres (the size of around 77 football pitches) and produces 50MW of power.

Protermosolar, the association that represents the solar energy sector, says that within a year another 600MW will have come on-stream and projects that by 2013 solar capacity will have reached 2,500MW.
