Electric Aggregation


Earlier this year the Town approved a change in its aggregation program energy supplier from Homefield Energy to Constellation Energy. Due to this change in suppliers, Normal residents and small business customers participating in aggregation may receive a notice from Ameren notifying them of this change. If you are participating in aggregation and receive a letter regarding “Electric Supplier Choice Expiring”, no action is required.

Normal residents participating in the Town’s aggregation program will receive a notice from Ameren confirming Constellation as their energy supplier. If you have additional questions or to verify your participation in aggregation, please contact Constellation directly at 1-844-278-2501.

Opt-In Letters

Constellation recently acknowledged several residents participating in the Town’s municipal aggregation program inadvertently received an “opt-in” notification, as opposed to the “opt-out” notice. Residents who inadvertently received the “opt-in” notification will soon receive a follow up letter from Constellation acknowledging this error and confirming their status in the aggregation program.

If you have already responded to “opt-in” or have not done so and wish to continue participating in municipal aggregation, there is nothing more you need to do.

If you have additional questions regarding the letter you received or decide to “opt-out” of the program, please contact Constellation directly at 1-844-278-2501.


Normal residents have the option to participate in a program that provides energy cost savings. In March, the Town signed an agreement with Constellation Energy to supply electrical power to its residents through municipal aggregation. The contract with Constellation, an Exelon Company, locks in rate of 5.765¢ per kilowatt hour for the term of June 2016 through June 2018. Constellation also offers a 100% renewable energy option available at a rate of 5.875¢ per kilowatt hour for the same 24 month duration. This compares with Ameren Illinois’ rate of 6.772¢ per kilowatt hour.

The aggregated rate is available to Ameren Illinois customers; Normal residents served by Corn Belt Energy, an electrical cooperative, are not eligible. All Ameren residential and some small business customers should be receiving an “opt out” letter from Constellation. Customers who do not want to participate in aggregation should return the opt out form to Constellation. Customers who do not return the form will receive a second notice from Ameren Illinois giving them an additional opportunity to opt out of the program. Normal customers who choose not to opt out should experience the new Constellation energy rates in June with savings reflected in the July electric bills.

For additional questions please consult the FAQs or contact Constellation Energy directly at 1-844-278-2501.


Frequently Asked Questions

  1. When was aggregation approved?
    Normal residents approved electrical aggregation in the November 2012 General Election. As of this April, 602 Illinois communities, counties, and townships now take advantage of energy cost savings through aggregate electrical use. Electric aggregation offers residents a convenient option to manage energy costs by locking in a competitive rate for a 24 month term.

  2. Is participation mandatory?
    Residential rate customers will have two opportunities to “opt out” of the program. The chosen electrical supplier, and the existing supplier, Ameren, will each contact eligible customers by mail to offer the opportunity to opt out of aggregation at no charge. Opt out notices will be provided to all eligible participants before the program begins.

  3. Will I receive two electric bills?
    Residents will continue to receive a single electric bill from their current provider, Ameren. Residents with a budget bill paying plan will remain on the plan. The only difference residents will see on their bills will be the rate and the listing of the new supplier’s name.

  4. What part of electricity bills will this program affect?
    Electricity bills have three cost components – transmission, distribution, and supply. Municipal aggregation changes only the supply component of your bill. Through aggregation, approximately 50% to 75% of the electricity bill will be impacted. The other components, transmission and distribution, will not be affected.

  5. Why did the rate increase?
    The new rate reflects changes to the energy market that have occurred since the previous contract with Homefield Energy was approved. The current rate reflects the best available bid by a responsible bidder.

  6. Why do I have to opt out?
    The referendum passed by voters in 2012 approved an “opt out” aggregation program. The opt out program automatically combines the electric load for residential and eligible small businesses for purchasing purposes except for those customers who actively choose not to participate in the municipality's or county's purchase program.

  7. How do I opt out?
    In order to be excluded from the aggregation program you will need to fill out and return the opt-out notice you receive from Constellation. You may also Call Constellation directly at 1-844-278-2051 or use the following link to opt out online www.constellation.com/il-normal.

  8. Why did I receive an Opt-In letter?
    Some business and residential aggregation program participants inadvertently received an “opt-in” notice from Constellation. If you already responded to “opt-in”, no further action is required.

    Residents currently participating in municipal aggregation will transition from Homefield to the Constellation program.
