Weather peril exposure
AEP WATERFORD FACILITY is a 922 MW natural gas power plant in Washington County, OH, operated by OHIO POWER CO, commissioned in 2003. Washington County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.6 of 5 at the 39th national percentile. Riverine flooding is the leading peril, rated Relatively Moderate by FEMA at the 88th 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.
