About electricity rates in Illinois

Illinois was among the first states to restructure its electricity market, and retail choice is well established. Commonwealth Edison delivers power across northern Illinois including Chicago, and Ameren Illinois serves the central and southern parts of the state; both are regulated by the Illinois Commerce Commission. Households may buy supply from an alternative retail supplier, join a municipal aggregation program in which their town chooses a supplier for all residents, or take default supply procured by the Illinois Power Agency.

Illinois generates more nuclear power than any other state, with natural gas, wind and a declining amount of coal making up the rest. The northern and southern parts of the state belong to different regional grids, PJM and MISO. Cold winters are heated mostly with natural gas, while hot, humid summers drive air-conditioning demand. Net metering is available for rooftop solar.
