Weather peril exposure
KENNECOTT POWER PLANT is a partly retired 220 MW coal power plant in Salt Lake County, UT, operated by KENNECOTT UTAH COPPER. Salt Lake County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.6 of 5 at the 15th national percentile. Earthquake is the leading peril, rated Relatively High by FEMA at the 97th 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.

|---|---|
| Hurricane | FEMA rating is "Not Applicable" for this county |
| Coastal flooding | FEMA rating is "No Rating" for this county |
