WATAUGA, a 58 MW Hydro power plant in Carter County, Tennessee. Operated by TENNESSEE VALLEY AUTHORITY, commissioned 1949.

How WATAUGA compares

With 58 MW of capacity, WATAUGA ranks 30th among the 53 operating power plants Bywatts maps in Tennessee and 18th of the 29 operating Hydro plants in the state. It accounts for about 1.4% of Tennessee's operating Hydro capacity and 0.3% of all operating capacity in the state. Nationally it is the 263rd-largest of the 1,243 operating Hydro plants in the database. Commissioned in 1949, it is older than 67% of the 53 operating Tennessee plants with a recorded commissioning year. Its operator, TENNESSEE VALLEY AUTHORITY, runs 32 operating plants in Tennessee totaling 19,142 MW. It shares Carter County with one other operating plant, WILBUR.

EIA-860 lists 2 generators at the site with 58 MW of nameplate capacity, all conventional hydroelectric technology. Net generation was 155 GWh in 2024 (a 31% capacity factor), up 42% from 2022.

Weather peril exposure

WATAUGA is a 58 MW hydro power plant in Carter County, TN, operated by TENNESSEE VALLEY AUTHORITY, commissioned in 1949. Carter County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.4 of 5 at the 10th national percentile. Riverine flooding is the leading peril, rated Relatively Moderate by FEMA at the 81st 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.
