Weather peril exposure
MCCLELLAN is a 136 MW natural gas power plant in Ouachita County, AR, operated by ARKANSAS ELECTRIC COOP CORP, commissioned in 1972. Ouachita County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.3 of 5 at the 83rd national percentile. Lightning is the leading peril, rated Relatively Moderate by FEMA at the 97th 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.
