Weather peril exposure
KEMPER COUNTY is a 372 MW natural gas power plant in Kemper County, MS, operated by TENNESSEE VALLEY AUTHORITY, commissioned in 2002. Kemper County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.8 of 5 at the 69th national percentile. Lightning is the leading peril, rated Relatively Low by FEMA at the 98th 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.
