Electrical Aggregation Program

In 2012, voters passed a referendum authorizing the City to establish an electrical aggregation program to provide residents with a viable energy supply alternative to Ameren. In 2013, the City contracted with Homefield Energy to serve as the City’s electricity supplier. As part of the approval to allow aggregation, the City Council opted to purchase 100% of its energy from “green” sources. In 2017, the City extended the agreement, which will expire on December 31, 2020.

At the beginning of the 2013 contract term, the City’s negotiated rate was .04299 ¢/kWh (cents per kilowatt hour) compared to Ameren’s rate of .05467 ¢/kWh.  In the summer of 2017, Ameren lowered its delivery rate to .05369 ¢/kWh compared to the City’s rate of .06398 ¢/kWh. Ameren’s rate, although variable, has remained lower than the City’s rate through 2019.

On August 25, 2020, the City Council accepted Staff's recommendation to allow the current contract for municipal aggregation to expire on December 31, 2020. Following the contract expiration, residents will automatically be transitioned back to Ameren for electricity supply - resident don't need to take any action to complete this process.

Electrical Aggregation Fact Sheet

Residents are under no obligation to participate and are free to opt out of the program at no cost. If you wish to opt out, call Homefield Energy at 866-694-1262 between the hours of 7am and 7pm (CST) Monday-Friday. It may take up to two billing cycles for changes to become effective.

Things to Remember:

  • This rate is for energy supply only. Ameren will continue to deliver electricity to your home and their bill will include all the associated charges related to delivery and service. Only the kWh charge is affected by the aggregation program.
  • All residents are reminded to be careful of third-party energy suppliers that solicit their services door-to-door or by phone. No one from the City will ever come to your door to ask you to switch to a new supplier. The City requires a solicitor permit for anyone that sells door-to-door so if approached, please ask for the permit. Anyone that cannot produce the proper permit is operating illegally so you should ask them to leave your property and call the Carbondale Police Department non-emergency number at 618-457-3200.
  • This program is completely voluntary. In Illinois you have three choices for your electric supplier. You can remain supplied by Ameren and pay their monthly variable rates, you can find your own supplier, or you can participate in Carbondale’s program.
