Weather peril exposure
OSCEOLA WINDPOWER II is a 50 MW wind power plant in Osceola County, IA, operated by OSCEOLA WINDPOWER II, commissioned in 2008. Osceola County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.0 of 5 at the 50th national percentile. Winter weather is the leading peril, rated Relatively Moderate 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.
Osceola County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Winter weather | Relatively Moderate | 96th | 4.8 of 5 | 18.4 |
| Tornado | Relatively Low | 92nd | 4.7 of 5 | 0.32 |
| Heat wave | Very Low | 90th | 4.6 of 5 | 4.7 |
| Strong wind | Relatively Low | 84th | 4.4 of 5 | 4.0 |
| Ice storm | Relatively Low | 76th | 4.0 of 5 | 1.1 |
| Hail | Relatively Moderate | 55th | 3.2 of 5 | 5.7 |
| Lightning | Very Low | 43rd | 2.7 of 5 | 38.8 |
| Riverine flooding | Very Low | 31st | 2.2 of 5 | 0.36 |
| Wildfire | Very Low | 28th | 2.1 of 5 | <0.01 |
| Earthquake | Very Low | 12th | 1.5 of 5 | <0.01 |
