Weather peril exposure
HOOT LAKE is a partly retired 131 MW coal power plant in Otter Tail County, MN, operated by OTTER TAIL POWER CO. Otter Tail County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.9 of 5 at the 21st national percentile. Winter weather is the leading peril, rated Very High by FEMA at the 93rd 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.

Perils not assessed in Otter Tail 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 |
| Coastal flooding | FEMA rating is "Not Applicable" for this county |
