Weather peril exposure
ALMA is a retired 136 MW coal power plant in Buffalo County, WI, formerly operated by DAIRYLAND POWER COOP. Buffalo County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.9 of 5 at the 72nd national percentile. Lightning is the leading peril, rated Relatively Low by FEMA at the 88th 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.
