Weather peril exposure
ST LUCIE is a 2,160 MW nuclear power plant in St. Lucie County, FL, operated by FLORIDA POWER & LIGHT CO, commissioned in 1976. St. Lucie County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.4 of 5 at the 85th national percentile. Hurricane is the leading peril, rated Very High by FEMA at the 98th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a nuclear plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
