Geothermal power is energy derived from the heat of the earth's core. "Geo" means "from the earth" and "thermal" means "heat." This type of energy is clean and predictable, offering a reliable and renewable energy source. In the Mayacamas Mountains, located north of San Francisco, naturally occurring steam field reservoirs below the earth's surface are being harnessed by Calpine to make clean, green, renewable energy for homes and businesses across Northern California.
The Geysers, comprising 45 square miles along the Sonoma and Lake County border, is the largest complex of geothermal power plants in the world. Calpine, the largest geothermal power producer in the U.S., owns and operates 14 power plants at The Geysers with a net generating capacity of about 725 megawatts of electricity - enough to power 725,000 homes, or a city the size of San Francisco.
Calpine offers free community tours departing from the Visitor Center in Lake County as well as from Sonoma County destinations. Calpine tours are led by our expert staff and no tour is the same!
