Weather peril exposure
PERRY is a 1,312 MW nuclear power plant in Lake County, OH, operated by FIRSTENERGY NUCLEAR OPERATING COMPANY, commissioned in 1987. Lake County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.0 of 5 at the 25th national percentile. Winter weather is the leading peril, rated Relatively High by FEMA at the 84th 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.

Model hail, wind and flood exposure for Lake County in the weather risk calculator
Ratings are the FEMA National Risk Index county hazard ratings; the peril score is a Bywatts transform of the FEMA national percentile. Full data sources and the solar vulnerability methodology are in the weather risk calculator.
Modeled estimate for screening and negotiation. Built from FEMA National Risk Index county hazard data and a solar vulnerability layer documented above.
