Ameren Missouri executed electric-service agreements in 2026 with large-load customers representing 2.8 gigawatts of demand, expected to begin materializing in the second half of 2027 and reach full capacity in 2030. Developers have signed construction agreements representing a further 1.2 gigawatts that is not yet secured by electric-service agreements. Ameren Missouri’s 2026 preferred resource plan estimates total load growth of 2.9 gigawatts by 2030, 5 gigawatts by 2035, and 6 gigawatts by 2045. Serving the increased demand is expected to require additional system-reliability and generation investment and may increase purchased-power costs until new generation enters service.
