The Price to Compare is the supply rate, the part of your bill you can shop. It is the benchmark a competitive ARES offer has to beat to save you money. It is not the same as the all-in average rate above, which also includes delivery.
Check whether you're aggregated first.
The Price to Compare is your benchmark to beat, but only if you're actually on it. If your community runs a municipal aggregation program, you were likely auto-enrolled in a different supply rate, and that aggregation rate is what an offer really has to beat. Look at your bill, or see how Illinois aggregation works, before you assume you're paying the ComEd default.
Delivery and outages
ComEd handles delivery and emergencies for Northern Illinois, including the Chicago metro, and operates in the PJM Interconnection grid region. Switching your supplier never changes who restores your power. To report an outage, call 800-334-7661.
