ASHDOWN, a 157 MW Biomass power plant in Little River County, Arkansas. Operated by DOMTAR INDUSTRIES INC, commissioned 1968.
How ASHDOWN compares
With 157 MW of capacity, ASHDOWN ranks 19th among the 48 operating power plants Bywatts maps in Arkansas and is the largest of the 4 operating Biomass plants in the state. It accounts for about 59% of Arkansas's operating Biomass capacity and 1.0% of all operating capacity in the state. Nationally it is the 3rd-largest of the 350 operating Biomass plants in the database. Commissioned in 1968, it is older than 72% of the 48 operating Arkansas plants with a recorded commissioning year.
EIA-860 lists 4 generators at the site with 157 MW of nameplate capacity, all wood/wood waste biomass technology. Net generation was 572 GWh in 2024 (a 42% capacity factor), down 5% from 2022. Its generators came online between 1968 and 1991.
Grid neighborhood
The closest transmission line found within 10 miles is a 138 kV line owned by SOUTHWESTERN ELECTRIC POWER CO, about 1.9 miles away. Another 2 operating power plants totaling 764 MW sit within 25 miles; the largest is JOHN W TURK JR POWER PLANT (609 MW).

Weather peril exposure
ASHDOWN is a 157 MW biomass power plant in Little River County, AR, operated by DOMTAR INDUSTRIES INC, commissioned in 1968. Little River County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.8 of 5 at the 94th national percentile. Ice storm is the leading peril, rated Very High by FEMA at the 99th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a biomass plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
