List of geothermal power stations in the United States

Geothermal power stations in the United States are located exclusively within the Western United States where geothermal energy potential is highest. The highest concentrations are located in the Mayacamas Mountains and Imperial Valley of California, as well as in Western Nevada.

The Sonoma Calpine 3 geothermal power station of The Geysers in California.
Main article: Geothermal energy in the United States

The first geothermal area to be exploited for commercial electricity generation was The Geysers, a complex of 22 geothermal power stations located in Sonoma and Lake counties of California, which was commissioned in September 1960.[1] The complex was then developed into the largest geothermal field in the world with a nameplate capacity of 1,517 MW and an annual generation of 6,516 GWh in 2018.[2][3]
