Solana Generating Station

Abengoa Solar has built a 280-megawatt parabolic trough solar plant about 70 miles southwest of Phoenix, Arizona. The plant generates enough power to supply 70,000 homes under a 30-year power supply contract with Arizona Public Service (APS). The thermal energy storage system provides up to 6 hours of generating capacity after sunset.
