LD 343 Maine House · 132nd Legislature (2025-2026)

An Act To Direct The Public Utilities Commission To Seek Informational Bids Regarding Small Modular Nuclear Reactors In The State

This bill requires Maine's Public Utilities Commission to annually request informational bids for small modular nuclear reactors (SMRs) by October 1st each year. SMRs are defined as reactors under 350 megawatts, NRC-licensed, and capable of on-site construction or transport. The bids must include costs, location, timeline, and operational details - though they are non-binding and used only to inform potential future contracts. The Commission must submit annual reports to the Legislature's energy committee starting in 2026, and the bill terminates once the state accepts a bid for reactor establishment.
