8-K: Ameren Illinois Secures Revised Rate Approval from Illinois Commerce Commission

The Illinois Commerce Commission approved revised revenue requirements for Ameren Illinois' electric distribution service for 2024-2027, resulting in a $285 million cumulative increase.

Summary

• The Illinois Commerce Commission (ICC) has approved a revised multi-year electric distribution service rate plan (MYRP) for Ameren Illinois, covering the years 2024 through 2027.
• This approval comes after a rehearing request filed by Ameren Illinois in February 2024 and updated in April 2024.
• The ICC's order, issued on June 20, 2024, grants a cumulative four-year revenue increase of $285 million compared to the 2023 revenue requirement.
• This is slightly less than the $305 million increase requested by Ameren Illinois in April 2024.
• The primary differences between the request and the approval are the removal of $12 million for other post-employment benefits and $7 million for 2023 projects deemed outside the scope of the rehearing.
• Ameren Illinois is seeking to recover these amounts through other filings.
• The new rates will take effect on June 27, 2024, and will remain in place until the ICC rules on Ameren Illinois' revised Grid Plan and MYRP, expected by December 2024 with rates effective in January 2025.
• Ameren Illinois' appeal of a previous ICC order remains pending before the Illinois Appellate Court.
