About Energy Choice in Naperville
Naperville is one of the higher-usage residential markets in Illinois — large single-family homes across DuPage and Will counties, plenty of central AC in summer, and heat pumps and electric appliances trending up. In the ComEd-served portion of the city, that consumption profile makes the supply charge the biggest lever a household can pull, because ComEd's delivery and taxes are fixed by regulation while supply is genuinely competitive.
The mechanic is simple even if the acronym stack isn't. ComEd sets a Price to Compare each summer and winter under the oversight of the Illinois Commerce Commission and the Illinois Power Agency. Any ARES that beats that number can serve Naperville addresses; the switch is filed electronically, and ComEd continues to deliver the electrons, read the meter and respond when a storm knocks a Naperville substation offline.
Gas works on a parallel track. Nicor Gas runs the mains through Naperville and offers its Customer Select shopping program — the delivery charge stays with Nicor, but the 'gas supply' line item on the bill can be sourced from a certified third-party supplier. Naperville households that shop both fuels typically lock winter gas and summer electric in different months to catch each market's softer season.
One Naperville-specific caveat: parts of the city are historically served by the municipal Naperville Electric Utility rather than ComEd. Municipal service is not part of Illinois deregulation and can't be shopped. Compare plans against the bill you actually receive — if it says ComEd on it, you're a shopping candidate.

Frequently Asked Questions
Is electricity deregulated in Naperville?
Yes for ComEd-served Naperville addresses. Illinois's retail choice program lets those households pick an Alternative Retail Electric Supplier while ComEd remains the delivery utility. Portions of Naperville served by the municipal electric utility are not part of the deregulated market.
Who delivers natural gas in Naperville?
Nicor Gas delivers natural gas to Naperville. Through Nicor's Customer Select program, residents can choose a competing gas supplier while Nicor continues to operate the distribution pipes and respond to gas leaks.
How much can Naperville households save by switching?
It depends on how much the household uses and how ComEd's Price to Compare moves at its next reset. Larger Naperville homes with heavy summer AC or all-electric appliances tend to see the biggest dollar swing from locking in a fixed 12- or 24-month supply rate.
Does the switch change my ComEd account or bill format?
No. ComEd still sends the bill and the account number stays the same. The 'Supply Services' section shows your new supplier and rate instead of ComEd's Price to Compare; delivery, taxes and riders stay on ComEd's side.
Who do I call for a power outage in Naperville?
ComEd customers call 800-334-7661 for outages. Naperville addresses on the municipal Naperville Electric Utility call the city's utility line. Retail suppliers do not handle outages under any circumstances.
