Weather peril exposure
DALE HOLLOW is a 54 MW hydro power plant in Clay County, TN, operated by USCE-NASHVILLE DISTRICT, commissioned in 1948. Clay County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.3 of 5 at the 82nd national percentile. Riverine flooding is the leading peril, rated Very Low by FEMA at the 94th 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.
