Ameren Illinois is responsible for the delivery of electricity and natural gas to customers. The utility is regulated by the Illinois Commerce Commission and subject to federal regulatory oversight.
We strive to keep rates low; when our costs rise, we submit a rate case and request approval from the Illinois Commerce Commission in order to keep delivering reliable, safe energy to your home and business.
