Municipal Aggregation Supplier Information

Residents may have received notices regarding Energy Harbor, our new local Electric Municipal Aggregation supplier. Energy Harbor replaced Homefield Energy, whose contract expired last year. With the change in supplier, these notices were mailed to homeowners and businesses giving them the option to voluntarily opt out of the program.

Residents have choices on how they get their energy supplied. Some residents choose to stay with Ameren as their supplier, some choose our local aggregate/group buying program, and others may choose to go with third-party suppliers. Residents wishing to stay with the aggregate do not have to take any action.

The aggregate’s goal is to lock in the best available rates for the long-term and attempt to avoid the volatility in the market. Currently, the aggregate is in a contract through December 2025 with a guaranteed base rate of $.097. Ameren recently filed rates that are estimated to be $0.08450-$0.08650.

It is up to the individual resident to choose which supplier they would like to use. Of note, the aggregate group is well-positioned to avoid short-term variations in the market due to their locked-in low pricing, whereas Ameren supply customers are more exposed to fluctuations in the energy market. Third-party solicitors may promise different rates, but residents should be aware of introductory prices that escalate after a few months as they evaluate pricing.

Please note that there is a utility hold after leaving the aggregation and returning to Ameren. They must remain with the Ameren for 12 months. 

Residents with questions on the aggregate program are encouraged to call Energy Harbor at 1-877-793-8921.
