Weather peril exposure
ST BONIFACIUS is a 61 MW oil power plant in Carver County, MN, operated by GREAT RIVER ENERGY, commissioned in 1978. Carver County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.0 of 5 at the 75th national percentile. Strong wind is the leading peril, rated Relatively High by FEMA at the 94th 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.
Carver County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Strong wind | Relatively High | 94th | 4.8 of 5 | 4.7 |
| Heat wave | Relatively Low | 92nd | 4.7 of 5 | 6.3 |
| Hail | Relatively Moderate | 78th | 4.1 of 5 | 6.6 |
| Tornado | Relatively Moderate | 68th | 3.7 of 5 | 0.31 |

| Peril | Why it is not scored |
|---|---|
| Hurricane | FEMA rating is "Not Applicable" for this county |
| Coastal flooding | FEMA rating is "Not Applicable" for this county |
