Commercial Energy in Aurora, IL: Electricity & Gas
Last reviewed: 7/31/2026
By Illinois Commercial Energy editorial team · Reviewed by JakenEnergy commercial energy team
Aurora is Illinois' second-largest city and a significant commercial and industrial center in the Fox Valley — manufacturing, distribution, a growing data-center corridor, and a large office and retail base. A useful point of clarity for businesses: Aurora is a ComEd community, not a municipal electric utility.
Utilities in Aurora
- Electricity: ComEd is the delivery utility (Aurora is not municipal), with commercial supplier choice available. See the ComEd commercial guide.
- Natural gas: Nicor Gas is the delivery utility, with commercial supplier choice through Choices for You. See the Nicor Gas commercial guide.
Aurora spans Kane, DuPage, Will, and Kendall counties, but the electric and gas utilities are consistent citywide. Confirm from a recent bill for any specific address.
What shapes energy costs here
- Manufacturing and warehousing accounts are demand- and capacity-sensitive — see manufacturing and warehouse procurement.
- Data centers carry high, steady load where load factor and demand strategy matter.
- Office and retail accounts benefit from supply comparison and bill review.
Getting started
Provide 12 months of electric and gas bills for an Aurora facility (interval data helps for high-demand accounts), and the account can be reviewed and priced on matched terms through the procurement process. No savings figure is promised in advance.
