KENTUCKY MILLS, an 88 MW Biomass power plant in Hancock County, Kentucky. Operated by DOMTAR PAPER COMPANY LLC, commissioned 2001.
How KENTUCKY MILLS compares
With 88 MW of capacity, KENTUCKY MILLS ranks 22nd among the 31 operating power plants Bywatts maps in Kentucky and is the largest of the 2 operating Biomass plants in the state. It accounts for about 95% of Kentucky's operating Biomass capacity and 0.4% of all operating capacity in the state. Nationally it is the 29th-largest of the 350 operating Biomass plants in the database. Commissioned in 2001, it is newer than 73% of the 30 operating Kentucky plants with a recorded commissioning year.
EIA-860 lists 1 generator at the site with 88 MW of nameplate capacity, all wood/wood waste biomass technology. Net generation was 286 GWh in 2024 (a 37% capacity factor), down 16% from 2022.
Grid neighborhood
The closest transmission line found within 10 miles is a 161 kV line, under 0.1 miles away. One other operating power plant sits within 25 miles: ROCKPORT (2,600 MW, Coal).

Weather peril exposure
KENTUCKY MILLS is an 88 MW biomass power plant in Hancock County, KY, operated by DOMTAR PAPER COMPANY LLC, commissioned in 2001. Hancock County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.4 of 5 at the 86th national percentile. Riverine flooding is the leading peril, rated Relatively Low by FEMA at the 95th 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.
