Weather peril exposure
CAYUGA is a 1,193 MW coal power plant in Vermillion County, IN, operated by DUKE ENERGY INDIANA INC, commissioned in 1970. Vermillion County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.7 of 5 at the 68th national percentile. Heat wave is the leading peril, rated Very Low by FEMA at the 86th 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.
