DAM 2, a 103 MW Hydro power plant in Desha County, Arkansas. Operated by ARKANSAS ELECTRIC COOP CORP, commissioned 1999.
How DAM 2 compares
With 103 MW of capacity, DAM 2 ranks 23rd among the 48 operating power plants Bywatts maps in Arkansas and 4th of the 19 operating Hydro plants in the state. It accounts for about 7.6% of Arkansas's operating Hydro capacity and 0.6% of all operating capacity in the state. Nationally it is the 175th-largest of the 1,243 operating Hydro plants in the database. Commissioned in 1999, it is newer than 58% of the 48 operating Arkansas plants with a recorded commissioning year. Its operator, ARKANSAS ELECTRIC COOP CORP, runs 9 operating plants in Arkansas totaling 2,033 MW. It shares Desha County with one other operating plant, CLEARWATER PAPER APP CB.
EIA-860 lists 3 generators at the site with 103 MW of nameplate capacity, all conventional hydroelectric technology. Net generation was 401 GWh in 2024 (a 44% capacity factor), up 9% from 2022.
Grid neighborhood
The closest transmission line found within 10 miles is a 115 kV line owned by ENTERGY ARKANSAS INC, under 0.1 miles away. One other operating power plant sits within 25 miles: CLEARWATER PAPER APP CB (20 MW, Biomass).

Weather peril exposure
DAM 2 is a 103 MW hydro power plant in Desha County, AR, operated by ARKANSAS ELECTRIC COOP CORP, commissioned in 1999. Desha County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.0 of 5 at the 50th national percentile. Earthquake is the leading peril, rated Relatively Low by FEMA at the 91st 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.
