Weather peril exposure
FITCHBURG is a 58 MW natural gas power plant in Dane County, WI, operated by MADISON GAS & ELECTRIC CO, commissioned in 1973. Dane County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.9 of 5 at the 72nd national percentile. Hail is the leading peril, rated Relatively High by FEMA at the 78th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a natural gas plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
