Weather peril exposure
LARKSPUR ENERGY FACILITY is a 100 MW natural gas power plant in San Diego County, CA, operated by DIAMOND GENERATING CORPORATION, commissioned in 2001. San Diego County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.3 of 5 at the 33rd national percentile. Wildfire is the leading peril, rated Very High by FEMA at the 100th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a natural gas plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
