Missouri Explores Nuclear Energy Expansion Amid Growing Power Demand

Missouri is actively exploring nuclear energy expansion to meet rising electricity demands, particularly driven by the growth of AI data centers and the need for reliable, carbon-free power. The state held its first Missouri Nuclear Summit, gathering lawmakers, energy officials, and industry leaders to discuss the role of nuclear power, with Ameren's Callaway reactor currently providing 14% of the state's electricity and plans to increase nuclear's share to about 40% by 2045. Despite enthusiasm, challenges remain, including long construction times, high costs, and regulatory hurdles, although recent legislation like Senate Bill 4 aims to ease financial burdens for utility companies. Smaller modular reactors are also viewed as a promising technology that could help replace fossil fuel plants and integrate with renewable energy sources. However, skepticism exists about Missouri's ability to attract large AI data centers compared to other states due to infrastructure and incentive limitations. Overall, nuclear energy is seen as a critical, dispatchable, and clean energy source essential for Missouri's future energy security and economic competitiveness.
