Weather peril exposure
POST ROCK WIND POWER PROJECT, LLC is a 201 MW wind power plant in Ellsworth County, KS, operated by POST ROCK WIND POWER PROJECT, LLC, commissioned in 2012. Ellsworth County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.5 of 5 at the 87th national percentile. Heat wave is the leading peril, rated Very Low by FEMA at the 97th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a wind plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
Ellsworth County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Heat wave | Very Low | 97th | 4.9 of 5 | 9.2 |
| Ice storm | Relatively High | 96th | 4.8 of 5 | 0.92 |
| Winter weather | Relatively Low | 92nd | 4.7 of 5 | 13.1 |
| Strong wind | Relatively Low | 90th | 4.6 of 5 | 6.2 |
| Hail | Relatively Low | 88th | 4.5 of 5 | 9.9 |
| Tornado | Relatively Low | 86th | 4.4 of 5 | 0.78 |
| Wildfire | Relatively Low | 85th | 4.4 of 5 | <0.01 |
| Lightning | Very Low | 73rd | 3.9 of 5 | 46.4 |
| Riverine flooding | Very Low | 45th | 2.8 of 5 | 0.86 |
| Earthquake | Very Low | 18th | 1.7 of 5 | <0.01 |
Perils not assessed in Ellsworth County
These perils carry no usable National Risk Index figure for this county, so they are excluded from the scoring rather than scored zero. A zero would claim the peril was assessed and found benign.
| Peril | Why it is not scored |
|---|---|
| Hurricane | FEMA rating is "No Rating" for this county |
| Coastal flooding | FEMA rating is "Not Applicable" for this county |
