Guam Power Authority Evaluates Nuclear Microreactors Amid Legislative Changes
The Guam Power Authority (GPA) has considered nuclear microreactor technology but has not engaged in formal discussions with the Department of Defense. If included in the fiscal year 2027 authorization act, microreactors could be mandated for Guam by January 2030, impacting energy infrastructure and military demands.

The Guam Power Authority (GPA) has acknowledged informal evaluations of nuclear microreactor technology but has not held official talks with the Department of Defense (DoD). Legislation under consideration could require the implementation of microreactors on Guam by January 2030.
GPA noted interest from various companies regarding small modular reactors, although discussions remain at a high level. A DoD team assessed Guam for potential reactor sites in 2024. GPA emphasizes its commitment to exploring advanced technologies for reliable energy, reflecting a decade of investment in cleaner generation and efficiency.
The U.S. Navy constitutes 20% of GPA's power sales, underlining the military's significant energy footprint on the island. Potential impacts on infrastructure and economic conditions remain uncertain, as GPA continues evaluations without any finalized decisions.
