Naperville commercial electricity at a glance
Naperville (DuPage and Will Counties) is served by Naperville Electric Utility, a municipal utility. Naperville runs its own municipal electric utility, so a Naperville business buys power from the city at its published rate and cannot contract a retail supplier. Neighboring Aurora, in ComEd territory, can. 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.
