The Geysers, a geothermal power operation located 72 miles (116 km) north of San Francisco, is the world's largest geothermal development in the world. It is also the largest producer of renewable energy in the United States, currently outputting over 750 MW.[1] The Geysers consists of 21 separate power plants that utilize steam from more than 350 producing wells. The Calpine Corporation operates and owns 19 of the 21 facilities. The other two facilities are operated by the Northern California Power Agency.
Description
The Geysers geothermal development spans an area of around 30 square miles (78 km2) in Sonoma and Lake counties in California, located in the Mayacamas Mountains. Power from The Geysers provides electricity to Sonoma, Lake, Mendocino, Marin, and Napa counties. It is estimated that the development meets 60 percent of the power demand for the coastal region between the Golden Gate Bridge and the Oregon state line.[1]
Steam used at the Geysers is produced from a greywacke sandstone reservoir, that is capped by a hetrogeneous mix of low permeability rocks and underlaid by a Felsite intrusion.[2]
