Weather peril exposure
MCGRATH PEAKER is a 50 MW natural gas power plant in Ventura County, CA, operated by SOUTHERN CALIFORNIA EDISON CO, commissioned in 2012. Ventura County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.0 of 5 at the 24th 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 natural gas plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
