The Energy Saving Program for Chicago households and small businesses. In keeping with the City of Chicago’s emphasis on offering programs to residents that are cost-effective, efficient and environmentally responsible, the following electricity supply offer from Integrys Energy Services is offered for Chicago residents. You'll still get your service and bills from ComEd, but with Integrys Energy, you pay a rate that's lower than ComEd's current rate1. The Metropolitan Mayors Caucus is pleased to present this program as part of the larger Clean Air Counts Initiative, a cooperative program in partnership with the US EPA, ILEPA and the City of Chicago.
