Pacific Gas and Electric Company (PG&E) and Southern California Edison will add 415 megawatts of solar power to California’s renewable energy mix, moving the state another step closer toward its renewable energy goals.
The California Public Utilities Commission approved last week PG&E’s 20-year power purchase agreements with Eurus Energy America Corporation, a renewable energy company based in Japan, for the 9-MW Avenal Park, 20-MW Sun City and 19-MW Sand Drag projects.
With a combined capacity of 48 MW, the solar photovoltaic facilities will provide the utility with approximately 77 gigawatt-hours of energy annually. The projects will be located near Fresno and are scheduled to begin operations in mid-2011.In addition, PG&E also secured a power purchase agreement with Genesis Solar L.L.C., an affiliate of NextEra Energy Resources L.L.C., which is a subsidiary of FPL Group The 25-year contract is for the 250-MW Genesis solar energy project in Riverside County.
The concentrating solar power facility will consist of two independent plants equipped with parabolic mirrors to produce a nominal net electric output of 125 MW each. The solar farm is expected to be online in 2013.
Meanwhile, the commission also approved Southern California Edison’s 20-year power purchase deal with Solar Partners I L.L.C., a subsidiary of BrightSource Energy Inc., for 117 MW of power from the Ivanpah solar electric generating system.Both PG&E, a subsidiary of PG&E Corporation , and Southern California Edison, the largest subsidiary of Edison International inked power purchase agreements with the Ivanpah complex, which would be one of the world’s largest concentrating solar power plant once it starts operations in 2013.
PG&E will purchase approximately two-thirds of the power generated from Ivanpah, while the rest will go to Southern California Edison.
The solar complex comprises three separate solar power plants and will have a total capacity of 392 MW, which is enough to power 140,000 homes while eliminating more than 400,000 tons of carbon dioxide emissions annually.
California’s renewable portfolio standard requires utilities and energy service providers in the state to secure 20 percent of their total retail sales from renewable energy sources by 2010 and 33 percent by 2020.
