Utility Southern California Edison said on Thursday it would spend $875 million to build a network of 250 megawatts of photovoltaic solar power generation, making it the biggest solar cell project in the nation.
SCE, a subsidiary of Edison International, said the photovoltaic cells on 65 million square feet of rooftops in southern California would generate enough power to serve 162,000 homes.
The project, which was submitted to state regulators for approval, is an effort to meet the state's mandate that 20 percent of California's electricity be generated from renewable sources by 2010.
