Ameren Missouri Seeks $343M Rate Hike Amid AI Demand and Grid Expansion
The latest in this situation
How it started
What happened
Ameren Missouri filed tariff sheets with the Missouri Public Service Commission requesting a net increase of approximately $343 million in annual electric base rate revenues, which would equate to about $13.00 per month for the average residential customer. The company is also expanding its smart grid technology across Missouri and plans to increase energy generation capacity by 50% over the next four years. The Public Service Commission set a deadline of July 15, 2026, for parties to intervene in the rate case.
Why it matters
The rate case discussion includes how much of the increased cost, driven partly by anticipated AI data center usage, should be borne by residential customers versus other customers. Ameren Missouri is seeking approval to recoup the cost of 400 new megawatts of power production.
