LAS VEGAS (AP) - The largest photovoltaic power plant in the U.S has started operating.
Sempra Generation, a subsidiary of San Diego-based power plant operator Sempra Energy, turned the switch on the 48-megawatt Copper Mountain solar facility in Boulder City, Nev., a week ago.
The company says the Nevada plant can generate enough electricity - when the sun is shining - to power about 14,000 homes.
The energy is being sold to Pacific Gas & Electric in California.
Other companies have larger solar power plants under development, but they use different solar technology.
