KINMUNDY, a 270 MW Natural Gas power plant in Marion County, Illinois. Operated by UNION ELECTRIC CO - (MO), commissioned 2001.
How KINMUNDY compares
With 270 MW of capacity, KINMUNDY ranks 36th among the 158 operating power plants Bywatts maps in Illinois and 21st of the 50 operating Natural Gas plants in the state. It accounts for about 1.8% of Illinois's operating Natural Gas capacity and 0.7% of all operating capacity in the state. Nationally it is the 487th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 2001, it is newer than 56% of the 150 operating Illinois plants with a recorded commissioning year. Its operator, UNION ELECTRIC CO - (MO), runs 5 operating plants in Illinois totaling 2,376 MW.
EIA-860 lists 2 generators at the site with 270 MW of nameplate capacity, all natural gas fired combustion turbine technology. The plant was a net consumer of electricity in 2024 (less than 0.1 GWh).
Grid neighborhood
The closest transmission line found within 10 miles is a 138 kV line owned by AMEREN ILLINOIS COMPANY, under 0.1 miles away. Another 2 operating power plants totaling 20 MW sit within 25 miles; the largest is CARLYLE (13 MW, Oil).

Weather peril exposure
KINMUNDY is a 270 MW natural gas power plant in Marion County, IL, operated by UNION ELECTRIC CO - (MO), commissioned in 2001. Marion County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.7 of 5 at the 42nd national percentile. Earthquake is the leading peril, rated Relatively Moderate by FEMA at the 94th 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.
