Weather peril exposure
MOUNTAINEER is a 1,300 MW coal power plant in Mason County, WV, operated by APPALACHIAN POWER CO, commissioned in 1980. Mason County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.0 of 5 at the 26th national percentile. Riverine flooding is the leading peril, rated Relatively Moderate by FEMA at the 95th 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.
