Understanding deregulation in Illinois

The term “deregulation” sounds complex, but it simply means you have the power to choose your energy supplier rather than being limited to one. Illinois deregulated its energy market in 1997, allowing private energy suppliers to compete with utility companies like Ameren. As a result, Illinois customers can now choose from various options for power suppliers. With many available companies, it’s important to compare Ameren Illinois rates per kWh in 2023 with other suppliers in your area.

Note that deregulation does not mean a lack of oversight. The Illinois Commerce Commission oversees all Illinois utility companies, including rates and tariffs for electricity and natural gas services in Ameren Illinois utility’s service area. You can contact the commission through its website or by calling the Consumer Services Division at 1-800-524-0795 to resolve any disputes with your supplier.

Choose Energy can be a one-stop shop for all the resources you need to understand deregulation and choose the supplier or Ameren Illinois plan that meets your needs. Enter your ZIP code to get started, or explore our guides to learn more about:
