San Francisco's Pacific Gas and Electric (NYSE: PCG)said today it signed a power purchase agreement for 150 megawatts of wind power from North Palm Springs, Calif.-based enXco.

EnxCo is a unit of France's EdF Energies Nouvelles.

"Wind energy is one of many renewable sources PG&E is seeking as we increase the amount of clean energy provided to our customers," said Fong Wan, VP of energy procurement for PG&E.

"Our 150 MW agreement with enXco is an important step towards PG&E exceeding 20 percent renewable electric power under contract or delivered by 2010."

The company currently supplies 12 percent of its energy from renewable sources. With today's long term contract, PG&E has 1,061 MW of wind energy under contract or delivered.

The wind power will come from enXco's Shiloh II project in Solano County, Calif., which is scheduled to go online in December 2008.

The project is expected to deliver 509 gigawatt hours of wind energy per year to PG&E's customers in northern and central California.

PG&E said it has contracts to provide 18 percent of its future energy supply from renewable sources and recently signed several other renewable energy agreements including a 553 MW solar thermal project with Solel, an 85 MW wind project with PPM Energy, 7 MW of utility-scale solar projects with Cleantech America and GreenVolts, and a 25.5 MW contract with Western GeoPower.
