Weather peril exposure
MARSHALL ENERGY FACILITY is a 688 MW natural gas power plant in Marshall County, KY, operated by TENNESSEE VALLEY AUTHORITY, commissioned in 2002. Marshall County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.1 of 5 at the 76th national percentile. Earthquake is the leading peril, rated Relatively Moderate by FEMA at the 95th 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.
