Weather peril exposure
MAGNOLIA POWER PLANT is a 1,004 MW natural gas power plant in Benton County, MS, operated by TENNESSEE VALLEY AUTHORITY, commissioned in 2003. Benton County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.7 of 5 at the 17th national percentile. Earthquake is the leading peril, rated Relatively Low by FEMA at the 92nd 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.
