Weather peril exposure
GRATIOT WIND PARK is a 102 MW wind power plant in Gratiot County, MI, operated by THE DTE ELECTRIC COMPANY, commissioned in 2011. Gratiot County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.8 of 5 at the 44th national percentile. Strong wind 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 wind plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
