(Undated) — Consumers are beginning to notice a rate hike in their Ameren bills. According to Ameren, now through September, Ameren Illinois’ “supply price” will increase by roughly 50 percent, going from around 8 cents per kWh to around 12 cents per kWh. They say this will result in an approximately 18% to 22% total bill increase for the typical residential customer for the summer period, depending on usage. Officials say that while there is a “sufficient supply” of electricity, the prices reflect a “tightening supply-demand balance,” thus driving prices upward. However, because of billing cycles, customers are only now becoming aware of the rate change. Beginning on October 1, 2025, the supply rate is expected to return “closer to current levels.” Information on available financial assistance, flexible payment programs, and energy-saving incentives is available at AmerenIllinois.com/options. Ameren Illinois also offers a variety of energy efficiency programs, which can be explored at AmerenIllinoisSavings.com.
