Weather peril exposure
QUAD CITIES GENERATING STATION is a 2,019 MW nuclear power plant in Rock Island County, IL, operated by EXELON NUCLEAR, commissioned in 1972. Rock Island County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.1 of 5 at the 78th national percentile. Hail is the leading peril, rated Relatively Moderate by FEMA at the 82nd 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.
