How MILL CREEK compares
With 1,717 MW of capacity, MILL CREEK ranks 6th among the 31 operating power plants Bywatts maps in Kentucky and 6th of the 12 operating Coal plants in the state. It accounts for about 10% of Kentucky's operating Coal capacity and 8.0% of all operating capacity in the state. Nationally it is the 51st-largest of the 324 operating Coal plants in the database. Commissioned in 1974, it is older than 56% of the 30 operating Kentucky plants with a recorded commissioning year. Its operator, LOUISVILLE GAS & ELECTRIC CO, runs 5 operating plants in Kentucky totaling 5,284 MW. It shares Jefferson County with 3 other operating plants, including CANE RUN and PADDYS RUN.
EIA-860 lists 3 generators at the site with 1,362 MW of nameplate capacity, all conventional steam coal technology (this page's HIFLD capacity figure is 1,717 MW). Net generation was 6,930 GWh in 2024, down 5% from 2022. Its generators came online between 1974 and 1982.

Weather peril exposure
MILL CREEK is a 1,717 MW coal power plant in Jefferson County, KY, operated by LOUISVILLE GAS & ELECTRIC CO, commissioned in 1974. Jefferson County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.8 of 5 at the 20th national percentile. Riverine flooding is the leading peril, rated Relatively High by FEMA at the 85th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a coal plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
