DERIDDER MILL, a 62 MW Biomass power plant in Beauregard Parish, Louisiana. Operated by BOISE PACKAGING & NEWSPRINT LLC, commissioned 1969.
How DERIDDER MILL compares
With 62 MW of capacity, DERIDDER MILL ranks 45th among the 72 operating power plants Bywatts maps in Louisiana and 3rd of the 6 operating Biomass plants in the state. It accounts for about 21% of Louisiana's operating Biomass capacity and 0.2% of all operating capacity in the state. Nationally it is the 57th-largest of the 350 operating Biomass plants in the database. Commissioned in 1969, it is older than 68% of the 72 operating Louisiana plants with a recorded commissioning year.
EIA-860 lists 1 generator at the site with 62 MW of nameplate capacity, all wood/wood waste biomass technology. Net generation was 402 GWh in 2024 (a 74% capacity factor), down 1% from 2022.
Grid neighborhood
The closest transmission line found within 10 miles is a 138 kV line, under 0.1 miles away. One other operating power plant sits within 25 miles: TOLEDO BEND (81 MW, Hydro).
