Weather peril exposure
WOLF CREEK GENERATING STATION is a 1,268 MW nuclear power plant in Coffey County, KS, operated by WOLF CREEK NUCLEAR OPTG CORP, commissioned in 1985. Coffey County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.3 of 5 at the 82nd national percentile. Lightning is the leading peril, rated Relatively High by FEMA at the 89th 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.
Coffey County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Lightning | Relatively High | 89th | 4.6 of 5 | 52.1 |
| Ice storm | Relatively Moderate | 86th | 4.5 of 5 | 0.74 |
| Wildfire | Relatively Low | 86th | 4.4 of 5 | <0.01 |
| Strong wind | Relatively Moderate | 84th | 4.4 of 5 | 5.9 |
| Hail | Relatively Low | 84th | 4.4 of 5 | 7.7 |
| Riverine flooding | Relatively Low | 83rd | 4.3 of 5 | 1.1 |
| Winter weather | Relatively Moderate | 82nd | 4.3 of 5 | 10.8 |
| Heat wave | Relatively Low | 81st | 4.2 of 5 | 14.4 |
| Tornado | Relatively Low | 78th | 4.1 of 5 | 0.45 |
| Earthquake | Very Low | 37th | 2.5 of 5 | <0.01 |
Perils not assessed in Coffey County
