Solar Plant to Generate Power, Rain or Shine

Something new is headed for the Southwest desert: solar power plants that can make electricity whether or not the sun is shining.

Abengoa Solar Inc. expects to start construction in mid-2011 on a plant in Arizona that will store sun-generated heat to provide six extra hours a day of electric-generating capacity. The heat creates steam that is used to turn power turbines.

Abengoa's $2 billion Solana plant is expected to be the first major stored-heat plant in the U.S. when it enters service in 2013. Some already exist in Spain and a few more are on the drawing board for Nevada and California.
