Weather peril exposure
BUFFALO GAP 2 WIND FARM is a 233 MW wind power plant in Nolan County, TX, operated by AES WIND GENERATION INC, commissioned in 2007. Nolan County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.5 of 5 at the 89th national percentile. Hail is the leading peril, rated Relatively Moderate by FEMA at the 90th 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.
Nolan County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Hail | Relatively Moderate | 90th | 4.6 of 5 | 5.3 |

| Wildfire | Relatively Low | 84th | 4.3 of 5 | <0.01 |
| Tornado | Relatively Low | 68th | 3.7 of 5 | 0.61 |
| Heat wave | Relatively Low | 64th | 3.6 of 5 | 9.6 |
| Lightning | Relatively Low | 48th | 2.9 of 5 | 48.0 |
| Winter weather | Relatively Moderate | 31st | 2.2 of 5 | 5.9 |
| Ice storm | Very Low | 25th | 2.0 of 5 | 0.32 |
| Hurricane | Very Low | 24th | 2.0 of 5 | <0.01 |
