Weather peril exposure
SILVER BAY POWER is a 132 MW coal power plant in Lake County, MN, operated by CLEVELAND CLIFFS INC, commissioned in 1955. Lake County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.8 of 5 at the 21st 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 coal plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
Lake County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Winter weather | Relatively Moderate | 96th | 4.8 of 5 | 24.5 |
| Lightning | Relatively Moderate | 89th | 4.6 of 5 | 25.1 |
| Riverine flooding | Very Low | 73rd | 3.9 of 5 | 0.29 |

Perils not assessed in Lake County
These perils carry no usable National Risk Index figure for this county, so they are excluded from the scoring rather than scored zero. A zero would claim the peril was assessed and found benign.
| Peril | Why it is not scored |
|---|---|
| Hurricane | FEMA rating is "Not Applicable" for this county |
| Earthquake | FEMA rating is "No Rating" for this county |
