Should states prioritize new nuclear power development to ensure long-term energy reliability?
The Missouri Department of Natural Resources released the 2026 State Energy Plan on September 30, shifting the state's energy policy to prioritize nuclear power. The proposal aims to replace the current Renewable Energy Standard with an Advanced Energy Standard to support these initiatives.
Why it matters
Missouri has transitioned from a net exporter to a net importer of electricity over the last decade, raising concerns regarding grid reliability and energy independence. This plan seeks to reverse that trend by incentivizing new generation capacity.
Missouri imported over 15% of its electricity in 2025, marking a significant shift from its historical net-exporter position. The state proposes an Advanced Energy Standard to facilitate the inclusion of new nuclear power sources.
The players
Ameren Missouri
A utility company managing electric and gas services that operates the Callaway Energy Center.
Mike Kehoe
The Governor of Missouri who established the state's Advanced Nuclear Energy Task Force.
The details
The plan authorizes the Environmental Improvement and Energy Resources Authority, a state agency, to issue loans specifically for nuclear projects. Additionally, Ameren Missouri has outlined a 20-year resource strategy that includes adding 2,400 MW of battery storage by 2030 and pursuing an operational life extension for the existing Callaway Energy Center beyond 2044.
Timeline
January 2026: Gov. Mike Kehoe created the Advanced Nuclear Energy Task Force via executive order.
2025: Missouri relied on other states for more than 15% of its electricity supply.
September 28, 2026: Ameren Missouri announced its 20-year resource plan.
September 30, 2026: The Missouri Department of Natural Resources released the 2026 State Energy Plan.
October 1, 2026: The Missouri Advanced Nuclear Energy Task Force held a meeting.
The Tech Race
The transition from a Renewable Energy Standard to an Advanced Energy Standard marks a regulatory pivot designed to prioritize nuclear energy integration. This move aligns with Ameren Missouri's roadmap to develop 1,200 MW of new nuclear capacity by 2040.
Residents should anticipate long-term shifts in grid composition as the state moves to integrate 2,400 MW of battery storage by 2030. These changes aim to improve local reliability as the state attempts to lower its dependency on imported power.
The takeaway
Missouri's energy trajectory now heavily depends on nuclear expansion and storage integration to address persistent import reliance. Stakeholders should monitor the upcoming legislative sessions for the authorization of loan programs to support the proposed 1,200 MW of new nuclear capacity.
