Illinois Choice—Understanding Your Electric Supply Options
In Illinois, you have three basic choices for obtaining the electric supply you need. Two of those options are offered by your local Ameren Illinois Utility, and the third option allows you to purchase your power from a third-party “retail electric supplier,” where available.    We encourage our customers to explore all of their supply options. Regardless of your choice for electric supply, we are dedicated to delivering safe, reliable energy to you.
