Weather peril exposure
AES PETERSBURG is a 2,155 MW coal power plant in Pike County, IN, operated by INDIANAPOLIS POWER & LIGHT CO, commissioned in 1967. Pike County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.8 of 5 at the 44th national percentile. Earthquake is the leading peril, rated Relatively Low by FEMA at the 91st 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.
