Weather peril exposure
FIRSTENERGY MAD RIVER is a retired 54 MW oil power plant in Clark County, OH, formerly operated by FIRSTENERGY GENERATION CORP. Clark County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.8 of 5 at the 45th national percentile. Heat wave is the leading peril, rated Relatively Low by FEMA at the 84th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to an oil plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
