NORTH BRAWLEY GEOTHERMAL PLANT, a 64 MW Geothermal power plant in Imperial County, California. Operated by ORMAT NEVADA INC, commissioned 2009.
How NORTH BRAWLEY GEOTHERMAL PLANT compares
With 64 MW of capacity, NORTH BRAWLEY GEOTHERMAL PLANT ranks 211th among the 874 operating power plants Bywatts maps in California and 8th of the 24 operating Geothermal plants in the state. It accounts for about 2.5% of California's operating Geothermal capacity and under 0.1% of all operating capacity in the state. Nationally it is the 8th-largest of the 34 operating Geothermal plants in the database. Commissioned in 2009, it is newer than 54% of the 859 operating California plants with a recorded commissioning year. Its operator, ORMAT NEVADA INC, runs 6 operating plants in California totaling 165 MW. It shares Imperial County with 33 other operating plants, including IMPERIAL VALLEY SOLAR LLC and EL CENTRO.
EIA-860 lists 5 generators at the site with 80 MW of nameplate capacity, all geothermal technology (this page's HIFLD capacity figure is 64 MW). Net generation was 16.9 GWh in 2024 (a 2.4% capacity factor), down 53% from 2022.

Weather peril exposure
NORTH BRAWLEY GEOTHERMAL PLANT is a 64 MW geothermal power plant in Imperial County, CA, operated by ORMAT NEVADA INC, commissioned in 2009. Imperial County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.4 of 5 at the 9th national percentile. Earthquake is the leading peril, rated Relatively High by FEMA at the 99th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a geothermal plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
