The City of Chicago's Electricity Aggregation Program has been underway for more than a year, saving Chicagoans more than $30 million as compared to what they would have paid ComEd. Additionally, all electricity sourced on behalf of the City's program is from completely coal free resources. As we are always looking for ways for more Chicagoans to benefit from this program, the City and Integrys worked to improve the program’s rate structure.
If (a) you were with another supplier at the time of the opt-out and your contract has now expired or (b) you previously opted-out of the program and would like to enroll, you can enroll now via this website.
There are no enrollment or switching fees.
If you have any questions, please call Integrys Energy Services, Inc. toll-free at 888-802-2885. Customer service representatives are available 7 days a week, 24 hours per day. Although the City of Chicago is offering this program, we ask that you direct all your aggregation program questions to Integrys Energy Services, Inc.
