Ameren CorpAmeren Missouri filed a rate review request to recover costs for grid and generation investments, which if approved will increase revenue.

Ameren Missouri has filed a request with the Missouri Public Service Commission to recover costs for electric system upgrades and new power generation, with new base rates not taking effect until mid-2027 after an 11-month review. The proposal would increase the average residential bill by about $13 per month, though the company says its residential rates are approximately 27% below Midwest and national averages and would remain well below those averages even if approved. The filing includes a new income-eligible discount rate that offsets the proposed adjustment for the most vulnerable customers, and the company expects $21 million in base rate savings over the next two years from committed data center customers. Key investments include storm-hardened infrastructure that prevented more than 260,000 customer outages during major storms from January 2025 through May 2026, as well as 400 megawatts of new generation from three energy centers expected online by the end of 2026.
