Solar 1 and Solar 2: Planned Facilities Using Sterling Energy Systems' SunCatcher

Solar 1 and Solar 2 are two giant planned solar facilities that will have a combined generating capacity of 1,740 megawatts. 1   The facilities are to be built by Arizona-based Stirling Energy Systems (SES), who will use their SunCatcher -- two-axis tracking dishes each equipped with a stirling engine.

The two projects are based on 20-year contracts with utilites signed in 2005. Solar One, to be sited on 1,821 hectares in the Mojave Desert, is planned to fulfil a contract with Southern California Edison. 2   Solar Two, to be sited on 777 hectares in the Imperial Valley, is planned to fulfil a contract with San Diego Gas and Electric Company that calls for the purchase of between 300 and 900 MW of power from the plant. 3   4   5   Stirling's plans call for the development of both plants in two phases.
