Weather peril exposure
SALTON SEA POWER LLC - UNIT 5 is a 50 MW geothermal power plant in Imperial County, CA, operated by CALENERGY OPERATING CORPORATION, commissioned in 2000. 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.
Imperial County hazard ratings
