Energy

SB 131 requires Oklahoma electric utilities planning to retire coal-fired power plants to prioritize replacing them with advanced nuclear reactors (including small modular reactors). Utilities must submit a cost study and written justification to the Corporation Commission if they choose alternatives to nuclear, and the Commission must approve or disapprove replacement plans. The bill also mandates that any entity building a nuclear plant must construct a secondary facility within the same zip code to store spent nuclear fuel and submit detailed applications to the Department of Environmental Quality. These provisions aim to guide the transition from coal to nuclear energy while establishing regulatory requirements for new nuclear construction. The bill becomes effective November 1, 2025.
