San Diego Gas & Electric (SDO-PH) announced that it has signed a four-year power-purchase agreement with Calpine Energy Services, L.P., a subsidiary of Calpine Corporation (CPN), to procure 25 MW 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 the Mayacamas Mountains, approximately 70 miles north of San Francisco. Calpine owns 725 MW of active installed capacity at the facility.
Under the agreement, which runs through 2014, the geothermal facility will contribute more than 200 gigawatt-hours per year of renewable energy toward SDG&E’s Renewable Portfolio Standard procurement goal.
