Abengoa launches world's biggest solar power tower

MADRID, April 27 (Reuters) – Spanish engineering company Abengoa has begun operating a 20 megawatt solar power plant that is the world’s biggest, using a tower to turn the sun’s rays into electricity and can supply 10,000 homes, it said on Monday.

The PS20 plant in the southern province of Seville uses 1,255 mirrors to focus solar radiation at the top of a tower 165 metres high, in order to boil water to drive a turbine and generate electricity.
