Chicago, IL commercial electricity rates
Who delivers electricity to Chicago businesses, how retail supplier choice works there, the Illinois commercial average with its EIA data month, and who regulates it. Market context with its source and date, never a quote.
EIA averages, data through 06/2026, published per state. All-in means supply and delivery together; supplier contract quotes cover the supply portion only, so the two are not directly comparable.
Chicago commercial electricity at a glance
Chicago (Cook County) is delivered by ComEd, which stays the wires company whichever supplier a business picks. Chicago is ComEd's home territory: the utility delivers to every business in the city and sends the bill whichever supplier is chosen. The EIA publishes a statewide figure, not a city one: the average Illinois commercial account paid 14.53¢ per kWh all-in, supply and delivery together, versus 14.19¢ nationally (EIA, 06/2026), and used about 5,964 kWh a month (EIA, through 2026). That average mixes corner stores with hospitals, so it is market context rather than a quote for any one business, and supplier contract quotes cover the supply portion only, so the two figures are not directly comparable. Voltcheckr LLC is registered as an electricity broker in Texas (PUCT Broker Registration BR260102) and is not currently registered in Illinois.
