Sempra opens Nevada photovoltaic plant

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.
