Weather peril exposure
ST CLAIR is a partly retired 1,571 MW coal power plant in St. Clair County, MI, operated by THE DTE ELECTRIC COMPANY. St. Clair County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.7 of 5 at the 17th national percentile. Heat wave is the leading peril, rated Relatively Low by FEMA at the 80th 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.
