The East Mesa geothermal power facility lies a few miles east of El Centro in southern California's Imperial Valley. Its moderate-temperature (300° to 375℉) resource is associated with the tectonic environment of the Salton Trough. After initial exploration efforts in the 1960s and 1970s, ORMAT (Sparks, NV) developed the field with the 24-megawatt (MW) Ormesa I project completed in 1986. By 1998, the facility was expanded by an additional 42-MW with ORMAT's Ormesa projects. In the years since then, the Geo East Mesa (GEM) and Ormesa operations were reliable power producers, but aging equipment and wells―and third party ownership and operation―led to inefficiencies in both geothermal fluid and power production.
