The Basin and Range geologic province in Nevada, southeastern Oregon, southwestern Idaho, Arizona and western Utah is now an area of rapid geothermal development. Several small power plants were built during the late 1980s during times of high power prices. Rising energy costs have spurred new development. The capacity of all 19 currently active geothermal power plants in Nevada is more than 486 MW. The largest plant is the McGinnis Hills facility operated by Ormat with a capacity of 96MW. Other geothermal plants in Nevada are at Steamboat Springs, Brady/Desert Peak, Dixie Valley, Soda Lake, Stillwater and Beowawe.
