The Geysers, a geothermal power field of 72 miles (116 km) north of San Francisco, California, is the largest geothermal development in the world. It produces over 750 MW. The Geysers has 22 separate power plants that use steam from more than 350 producing wells. The Calpine Corporation operates and owns 19 of the 22 facilities.
History
The Geysers was found by European Americans. It was named in 1847 by John Fremont during his research.
Between 1848 and 1854, Geysers worked as a spa complex The Geysers Resort Hotel. It was visited by such famous people as Ulysses S. Grant, Theodore Roosevelt and Mark Twain. But in 1938, the main building was destroyed in a landslide.
Five of the Geysers plants were destroyed in the Valley Fire of September 2015.
The Geysers Geothermal Power Development project was named as a California Historic Civil Engineering Landmark.
