Weather peril exposure
DIESEL GENERATORS is a 54 MW oil power plant in Dane County, WI, operated by MADISON GAS & ELECTRIC CO, commissioned in 2001. Dane County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.9 of 5 at the 72nd national percentile. Hail is the leading peril, rated Relatively High by FEMA at the 78th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to an oil plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
Dane County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Hail | Relatively High | 78th | 4.1 of 5 | 3.8 |
| Heat wave | Relatively Moderate | 60th | 3.4 of 5 | 3.5 |
| Tornado | Relatively High | 52nd | 3.1 of 5 | 0.93 |
| Lightning | Relatively High | 39th | 2.6 of 5 | 37.1 |
| Wildfire | Very Low | 34th | 2.4 of 5 | <0.01 |
| Strong wind | Relatively High | 21st | 1.8 of 5 | 4.4 |
| Earthquake | Relatively Low | 19th | 1.8 of 5 | <0.01 |
| Riverine flooding | Relatively High | 14th | 1.5 of 5 | 2.1 |
| Ice storm | Relatively High | 13th | 1.5 of 5 | 0.62 |
| Winter weather | Relatively High | 4th | 1.1 of 5 | 16.1 |
| Hurricane | Very Low | 2nd | 1.1 of 5 | <0.01 |
Perils not assessed in Dane County
