How Highland Park’s Rate Compares With ComEd

The Illinois Commerce Commission lists Highland Park’s rate as “ComEd Match PTC+PEA.” MC Squared Energy Services charges ComEd’s price to compare plus the Purchased Electricity Adjustment (PEA), so the supply price moves with ComEd’s default rate instead of staying fixed. ComEd’s price to compare is 10.103¢ per kWh from Oct 1, 2026 through May 31, 2027.

These are supply prices only. ComEd still delivers the power and bills its delivery charges either way.

How to Opt Out or Leave

Illinois rules are the same in every aggregation community. In the Illinois Commerce Commission’s words:

  • Opting out. “The chosen supplier will send opt-out notices to all residents and eligible small businesses within the municipality or county. You will need to fill out and return the opt-out notice in order to be excluded from the aggregation program.”
  • Leaving later. “Suppliers are prohibited from applying early termination fees or penalties to residential and small commercial retail customers who terminate their contracts and switch to a different supplier or go back to the utility's service.”
  • If you already buy from a supplier. “If you are enrolled with a supplier or the utility's residential real-time program at the time the opt-out notices are being sent out, you will likely not be included in your municipality's or county's aggregation program.”
