Major utilities in Illinois

Choosing a supplier in Illinois

Illinois has a competitive retail electricity market. The regulated utility still owns the wires and delivers the power, but the supply portion of the bill can come from the utility's regulated default rate — called Price to Compare in Illinois — or from a licensed third-party supplier. The EIA average above blends both, so an individual bill can sit above or below it depending on the supply contract.

Methodology & data

Average residential electricity price in cents per kWh from the published state-level dataset. Values are used as a reference benchmark for comparison and estimation.

Estimates use the EIA all-in average residential rate — energy, delivery, fixed charges, and utility fees together, not just the electricity itself. Fees are inside the rate, not an extra on top; how your own bill splits fixed versus per-kWh charges varies by utility.
