Electricity cost in Illinois
Illinois customers should separate supply, delivery and fixed charges when comparing bills. A statewide EIA average cannot identify the current utility or supplier terms for an address.
Calculate with your ZIP →What changes the real result?
- All-in delivered rate, fixed fees and time-of-use periods
- Actual monthly kWh and seasonal HVAC load
- Plan term, minimum-use rules, credits and early termination
- Solar export compensation and address-specific production
- EV charging losses, vehicle efficiency and charging time
DO NOT MIX THESE NUMBERS
Average price ≠ utility tariff ≠ retail offer.
EIA divides residential revenue by electricity sold to create an average-revenue benchmark. Your bill applies address-specific rate rules and fees. In competitive markets, compare the full disclosure document at your normal usage—not only the advertised cents per kWh.
