A dry steam geothermal plant is a type of geothermal power plant in which steam, generated underground by geothermal heat, is used directly, thus eliminating the need for boilers and boiler fuel that characterizes other steam-power-generating technologies. Conventional turbine generators are used with dry steam resources. This approach to utilizing geothermal energy is limited because dry-steam hydrothermal resources are extremely rare. The Geysers, in California, for example, is the only dry steam field in the United States.
