Weather peril exposure
GREERS FERRY LAKE is a 96 MW hydro power plant in Cleburne County, AR, operated by USCE-LITTLE ROCK DISTRICT, commissioned in 1964. Cleburne County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.0 of 5 at the 50th national percentile. Ice storm is the leading peril, rated Very High by FEMA at the 98th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a hydro plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
