South West Illinois News

My office has received numerous calls regarding the rising energy rates in Southern Illinois, particularly those associated with Ameren. I want to take a moment to explain what this means to you.

Starting June 1, 2025, through September 30, 2025, Ameren Illinois’s supply price, known as the Price to Compare, will increase by about 50%, going from around 8 cents per kWh to roughly 12 cents per kWh. For the average residential customer, this translates to an estimated 18%–22% increase in the total electric bill, which could amount to approximately $45 more per month during the summer, depending on your energy usage.

This increase follows an update Ameren received in April 2025 from the regional grid operator, MISO, where wholesale electric supply rates jumped significantly, from $30 per megawatt to $666 per megawatt. These higher wholesale costs are directly reflected in Ameren’s supply rates starting June 1.

Let me be clear: Ameren does not profit from supply rates. These costs are passed directly to consumers. However, the policy framework that dictates these rising rates is crafted and controlled by state agencies such as the Illinois Power Agency (IPA), which operate under the clear influence of Democratic majorities in the Illinois General Assembly. These are the same lawmakers pushing aggressive energy mandates without fully considering the financial burden they’re placing on working families.

It’s important to note that only customers on Ameren’s standard supply plan are affected. Customers using an Alternative Retail Electric Supplier (ARES) might not see the same increase. You can check your current energy provider by reviewing the “Electric Supply” section of your Ameren bill.

If you need help managing your electric or gas bills, my office has resources to assist you. I will continue to closely monitor this situation and work toward long-term solutions to ensure that all Illinois residents have access to affordable and reliable energy.
