Weather peril exposure
TWIN BUTTES WIND PROJECT is a 75 MW wind power plant in Bent County, CO, operated by IBERDROLA RENEWABLES INC, commissioned in 2007. Bent County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.8 of 5 at the 95th national percentile. Hail is the leading peril, rated Relatively Low by FEMA at the 96th 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.
Bent County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Hail | Relatively Low | 96th | 4.8 of 5 | 3.3 |
| Wildfire | Relatively Low | 82nd | 4.3 of 5 | <0.01 |
| Winter weather | Relatively Low | 61st | 3.5 of 5 | 6.8 |
| Riverine flooding | Very Low | 61st | 3.5 of 5 | 0.54 |
| Strong wind | Relatively Low | 59th | 3.4 of 5 | 0.99 |
| Tornado | Very Low | 50th | 3.0 of 5 | 0.81 |
| Earthquake | Very Low | 36th | 2.4 of 5 | <0.01 |
| Lightning | Relatively Low | 22nd | 1.9 of 5 | 44.4 |
| Heat wave | Very Low | 18th | 1.7 of 5 | 0.47 |
| Ice storm | Very Low | 9th | 1.4 of 5 | 0.01 |
