This is a list of electricity-generating power stations in the U.S. state of Illinois, sorted by type and name. In 2022, Illinois had a total summer capacity of 44,163 MW and a net generation of 185,223 GWh through all of its power plants.[2] In 2023, the electrical energy generation mix was approximately 54.9% nuclear, 15.9% natural gas, 15.3% coal, 12.4% wind, 1.1% solar, 0.2% biomass, 0.2% petroleum & other gases, 0.1% hydroelectric, and 0.1% other. Small-scale solar, which includes customer-owned photovoltaic panels, delivered an additional net 1,536 GWh of energy to the state's electrical grid in 2023.[1]

Illinois generated more energy from its six nuclear power stations than any other U.S. state in 2019.[3] Legislation in 2016 and 2021 provided state financial incentives which delayed the closure of several plants.[4][5]
