Bill Calculator ->ComEd on Form EIA-861: 2024 Reported Sales, Customers and Realised Prices
EIA's 2024 Form 861 census lists 1 operating company behind ComEd (Commonwealth Edison Co, utility 4110), together serving 3,727,675 residential accounts (bundled plus delivery-only) in IL across 24 counties. Weighted across those companies, the 2024 average realised residential price for bundled service was 15.22 cents per kWh (total residential revenue divided by total residential sales). These are annual averages of what customers actually paid, including fuel and rider charges, so they will not match the tariff rate on a current bill; the estimated effective rate above is the site's forward-looking figure.

Rank is by residential accounts served among the state's utilities with bundled or delivery service; share is the company's share of the state's residential sales in MWh, not of its customers. Delivery-only rows show the wires charge only. The 2025 early-release column is preliminary and unvalidated by EIA.
