Weather peril exposure
GERALD ANDRUS is a 781 MW natural gas power plant in Washington County, MS, operated by ENTERGY MISSISSIPPI INC, commissioned in 1975. Washington County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.1 of 5 at the 77th national percentile. Earthquake 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.
