Missouri pushes nuclear to reduce reliance on out-of-state electricity

Missouri's new state energy plan calls for expanding nuclear power, transmission capacity and redevelopment of former power plants to reduce the state's reliance on imported electricity. State officials say rising demand from AI data centers is increasing the need for reliable, around-the-clock generation, while data center projects are expanding in the Kansas City corridor and along Interstates 70 and 44.

Opinions split on Senate Bill 4: Consumer protections versus consumer skepticism

Missouri Senate Bill 4, passed in 2025, restructured utility regulation in the state to address concerns about power bills and data center energy consumption. The bill mandates "large-load tariffs" for investor-owned utilities serving data centers, requiring long-term contracts and payments for grid strain. While proponents laud it as a strict consumer protection measure, critics argue it may not go far enough and could still burden existing customers with costs related to new power generation for data centers.

‘They’re already here': Regulating data centers stalls in Missouri$

Missouri's efforts to regulate hyperscale data centers, particularly their energy consumption, are lagging behind their rapid expansion. Senate Bill 4, enacted last year, aims to make large energy users pay for their own infrastructure costs, but critics argue it has loopholes and could lead to increased reliance on natural gas and costs passed to consumers. Local communities are resorting to moratoriums in the absence of comprehensive state-level regulation.
