San Diego Gas & Electric is buying some renewable energy from a geothermal plant in Northern California. The new agreement moves the utility closer to meeting a state renewable energy mandate.

SDG&E signed a four-year power-purchase agreement with Calpine Energy Services to get 25 megawatts of geothermal energy from the Calpine Geysers facility in Northern California.

The Geysers facility is a complex of 15 geothermal power plants, drawing steam from more than 330 wells, located in mountains about 70 miles north of San Francisco.

The Geysers is the largest geothermal power producing site in the world.

Jennifer Briscoe with SDG&E parent company Sempra Energy, said the geothermal agreement will increase SDG&E's portfolio of clean power resources to approximately 14 percent ... And get the utility closer to meeting the state's 20-percent renewable mandate.

"We expect to definitely meet the 20 percent by 2010, and will do so with banked renewable energy from years past as well," said Briscoe.

Briscoe said under the agreement, the geothermal facility will produce enough "green" power for more than 15,000 households.
