Ameren Illinois has filed paperwork with the Illinois Commerce Commission seeking a rate adjustment that would increase the average household bill by about $2.75 per month for delivery of electricity. 

The filing is the second requested increase in delivery over the past six years. Ameren Illinois spokesperson Marcelyn Love says the increase would allow for continued investments in the electrical grid, reduce outages, and keep rates stable.

The ICC will conduct an open and transparent eight-month regulatory review of the rate adjustment request. A decision by the ICC is expected in December, with new rates effective in early 2022.
