CHEOAH, a 113 MW Hydro power plant in Graham County, North Carolina. Operated by BROOKFIELD RENEWABLE POWER, commissioned 1949.
How CHEOAH compares
With 113 MW of capacity, CHEOAH ranks 29th among the 205 operating power plants Bywatts maps in North Carolina and 5th of the 36 operating Hydro plants in the state. It accounts for about 5.8% of North Carolina's operating Hydro capacity and 0.4% of all operating capacity in the state. Nationally it is the 159th-largest of the 1,243 operating Hydro plants in the database. Commissioned in 1949, it is older than 87% of the 183 operating North Carolina plants with a recorded commissioning year. Its operator, BROOKFIELD RENEWABLE POWER, runs 2 operating plants in North Carolina totaling 158 MW. It shares Graham County with one other operating plant, SANTEETLAH.
EIA-860 lists 5 generators at the site with 140 MW of nameplate capacity, all conventional hydroelectric technology (this page's HIFLD capacity figure is 113 MW). Net generation was 485 GWh in 2024 (a 39% capacity factor), down 8% from 2022. Its generators came online between 1949 and 2013.

Weather peril exposure
CHEOAH is a 113 MW hydro power plant in Graham County, NC, operated by BROOKFIELD RENEWABLE POWER, commissioned in 1949. Graham County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.1 of 5 at the 27th national percentile. Riverine flooding is the leading peril, rated Relatively 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.

Perils not assessed in Graham County
These perils carry no usable National Risk Index figure for this county, so they are excluded from the scoring rather than scored zero. A zero would claim the peril was assessed and found benign.
| Peril | Why it is not scored |
|---|---|
| Coastal flooding | FEMA rating is "Not Applicable" for this county |
| Heat wave | FEMA rating is "No Rating" for this county |
