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.”
