Ameren 8-K, filed Sep 28, 2026

Summary

Union Electric Company, doing business as Ameren Missouri, filed its 2026 non-binding integrated resource plan with the Missouri Public Service Commission, outlining a preferred plan that adds natural gas, solar, wind, battery storage, and nuclear generation while retiring coal and certain natural gas capacity. The plan assumes load growth of roughly 2.9–3.9 GW by 2030, 5–6 GW by 2035, and 6–9 GW by 2045, and expects Ameren Missouri to seek and receive NRC approval to extend the Callaway nuclear energy center’s operating license beyond 2044.

Key points

• The preferred plan includes adding 2,100 MW of combined-cycle natural gas by 2031, 1,900 MW of simple-cycle natural gas by 2029, 500 MW of natural gas fuel cells by 2030, 1,300 MW of solar by 2030, 1,500 MW of wind by 2040, 2,400 MW of battery storage by 2030, and 1,200 MW of new nuclear by 2040.
• It extends the retirement date of two Labadie coal-fired units from 2036 to 2042 and retires about 1,800 MW of natural gas-fired energy centers by 2040.
• The plan expects Ameren Missouri to seek and receive Nuclear Regulatory Commission approval to extend the Callaway nuclear energy center’s operating license beyond its current 2044 expiration date.
• Ameren Missouri’s forecast for the preferred plan and high load growth scenarios ranges from about 2.9–3.9 GW by 2030, 5–6 GW by 2035, and 6–9 GW by 2045.
