Weather peril exposure
ROCKLAND WIND FARM is a 79 MW wind power plant in Power County, ID, operated by RIDGELINE ENERGY LLC, commissioned in 2011. Power County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.1 of 5 at the 28th national percentile. Wildfire is the leading peril, rated Relatively Moderate by FEMA at the 99th 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.
Power County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Wildfire | Relatively Moderate | 99th | 4.9 of 5 | 0.02 |
| Earthquake | Very Low | 84th | 4.3 of 5 | <0.01 |
| Lightning | Very Low | 62nd | 3.5 of 5 | 28.9 |
| Heat wave | Relatively Low | 50th | 3.0 of 5 | 2.4 |
| Winter weather | Relatively Moderate | 43rd | 2.7 of 5 | 15.6 |
| Strong wind | Very Low | 35th | 2.4 of 5 | 0.82 |
