This is a list of electricity-generating power stations in the U.S. state of Illinois, sorted by type and name. In 2024, Illinois had a total summer capacity of 46.3 GW and a net generation of 185,013 GWh through all of its power plants. In 2025, the electrical energy generation mix was approximately 50.5% nuclear, 16.8% natural gas, 16% coal, 12.9% wind, 3.4% solar, and less than 1% combined from biomass, petroleum & other gases, hydroelectric, and other. Small-scale solar, which includes customer-owned photovoltaic panels, delivered an additional net 2,256 GWh of energy to the state's electrical grid in 2025.
As of 2024, Illinois generates more energy from its six nuclear power stations than any other U.S. state. Legislation in 2016 and 2021 provided state financial incentives which delayed the closure of several plants.
