APS and Starwood Plan 290-MW Solar Project in Arizona

LCG, May 27, 2009--Arizona Public Service (APS) and Starwood Energy Group Global plan to construct a 290-MW concentrating solar plant (CSP) near Phoenix, Arizona. The Starwood Solar I plant is scheduled to be operational in 2013.

The facility will be designed, built and operated by Lockheed Martin, and it will be owned by an affiliate of Starwood Energy. APS will buy all of the electricity generated through a long-term purchase power agreement (PPA).

Starwood Solar I will employ a concentrated solar design that reflects solar energy with parabolic mirrors onto tubes filled with liquid. The heated liquid is used to convert water into steam that drives steam turbines that drive a generator.

The project includes a thermal storage system of molten salt to provide energy for power generation when direct solar energy is inadequate, which enables the plant to be dispatched when the sun is not shining. The project footprint covers a 1,900-acre site.
