Weather peril exposure
GREENVILLE ELECTRIC GENERATING STATION is a 236 MW natural gas power plant in Darke County, OH, operated by BUCKEYE POWER, INC, commissioned in 2000. Darke County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.8 of 5 at the 44th national percentile. Tornado is the leading peril, rated Relatively Moderate by FEMA at the 89th 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.
