MADISON, a 683 MW Natural Gas power plant in Butler County, Ohio. Operated by DUKE ENERGY INDIANA INC, commissioned 2000.
How MADISON compares
With 683 MW of capacity, MADISON ranks 13th among the 102 operating power plants Bywatts maps in Ohio and 6th of the 25 operating Natural Gas plants in the state. It accounts for about 7.2% of Ohio's operating Natural Gas capacity and 3.2% of all operating capacity in the state. Nationally it is the 207th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2000, it is newer than 45% of the 99 operating Ohio plants with a recorded commissioning year. It shares Butler County with 6 other operating plants, including WOODSDALE and DICKS CREEK.
EIA-860 lists 8 generators at the site with 692 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 1,045 GWh in 2024 (a 17% capacity factor), up 62% from 2022.

Weather peril exposure
MADISON is a 683 MW natural gas power plant in Butler County, OH, operated by DUKE ENERGY INDIANA INC, commissioned in 2000. Butler County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.1 of 5 at the 29th national percentile. Heat wave is the leading peril, rated Relatively Moderate by FEMA at the 89th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a natural gas plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
