From Affordable Gas & Electric, the electric aggregation consultant for the City of Carterville:

Last week Ameren IL announced their new price-to-compare for the summer service under their Basic Generation Service for electric supply.

The new price-to-compare will be $0.08136/kWh from Ameren’s BGS-1 electric supply service this summer (June 1, 2024 – September 30, 2024). The non-summer numbers will not be official until late September for the period of October 1, 2024 – May 31, 2025.

Obviously, this summer rate from Ameren comes in lower than our negotiated aggregation rate with Homefield Energy of $0.091/kWh.

Opt-out letters were mailed to residents last week and the opt-out deadline is June 19th in order to not be automatically enrolled on the aggregation rate from Homefield Energy. If a resident misses this deadline, they will be enrolled but can still opt-out at any time after without any penalties or early termination fees.

We want to be transparent about our aggregation programs and ensure residents are receiving a benefit from the program. Overall, the program has produced savings dating back to the beginnings, but there can be instances like now where Ameren’s rate for electric supply falls below our aggregation rate. To help address concerns from residents, here are a couple of frequently asked questions with answers you are welcome to share:

  1. What is the new electric aggregation rate from Homefield Energy? The new rate will be $0.091/kWh as part of the aggregation program from Homefield Energy. This is a 12-month fixed rate from July 1, 2024 to June 30, 2025.
  2. What is Ameren’s price-to-compare? Ameren’s price to compare for their Residential Basic Generation Service for electric supply will be $0.08136/kWh from June 1st to September 30th. Their non-summer rate will be officially announced towards the end of September for the period of October 1st to May 31st.
  3. If I opted-out of the aggregation program last fall, do I have to opt-out again this time? Yes, residents who opted out under a previous rate but are still eligible for the aggregation program and received an opt-out letter would have to opt-out again from the new rate to avoid being automatically enrolled in the aggregation program. Opt-out letters are mailed to all eligible residents every time the aggregation rate changes, regardless of whether you opted-out of a previous aggregation rate or not.
  4. If I do not opt-out by the June 19th deadline, will I have to stay in the aggregation program? No. Residents can opt-out of the program at any time by calling Homefield Energy at 866-694-1262. There is no penalty or early termination fee for residents to opt-out of the aggregation program after having already been enrolled.
  5. If I opt-out of the aggregation program now, can I rejoin the aggregation later? If you have been participating in the aggregation program with Homefield Energy as your electric supplier and opt-out now, then you may have to remain on a minimum stay period with Ameren for 12 months before you are eligible to rejoin the aggregation program. If Ameren is currently your electric supplier and you opt-out now, you should be able to rejoin the aggregation program at any time.
  6. Who should I contact if I wish to opt-out of the program? Homefield Energy handles all enrollments in and out of the aggregation program. Please call Homefield at 866-694-1262 if you wish to not participate in the aggregation program.  
  7. Is there someone else I can speak with about other questions I have about this program? Our community works with AGE as our consultant for our aggregation program. Jordan Haarmann is our primary point of contact with AGE. He can be reached at 618-203-8328 or
  8. What is being done to help lower costs in the future for the aggregation programs? SIAP Solar Inc. is a non-profit that has been formed with the purpose of building solar arrays throughout Southern Illinois that will directly benefit our aggregation program. These solar arrays will take advantage of government incentive dollars for renewable energy to be built at lower costs. Once constructed, the solar arrays will begin generating bill credits to residents participating in the aggregation program.

Thank you,
