Thailand's Electricity Generating Authority of Thailand (EGAT) and the US Trade and Development Agency (USTDA) have signed a grant agreement for an initial study into building a small modular reactor power plant in Thailand. The agreement, signed on Tuesday, 15 September at Gastech 2026 at Bangkok International Trade & Exhibition Centre (BITEC), will fund preliminary work on possible sites, costs and the regulatory steps needed before SMR technology could be introduced. Energy Minister Akanat Promphan, US Deputy Secretary of Energy James Danly, Energy Ministry Permanent Secretary Prasert Sinsukprasert and US Ambassador to Thailand Sean K. O'Neill witnessed the signing. Thomas R. Hardy, USTDA deputy director serving as acting director, signed for the US agency, while EGAT Governor Narin Phoawanich signed for Thailand's state power utility. Early work on sites, costs and regulations The study is not approval for a nuclear plant. It is intended to give EGAT an initial assessment of where an SMR facility could potentially be located, how much it may cost and what regulations and procedures would be required to take the plan further. Thailand is examining SMRs as a possible clean-energy option to improve energy security, keep electricity generation stable and support its carbon-neutrality aims. Hardy said the agreement demonstrated the US commitment to promoting American innovation and leadership in the peaceful use of nuclear energy and advanced nuclear technologies. He said it was part of a wider effort to revive and advance the US nuclear-energy sector through renewed support for innovation and investment, both in the United States and internationally. He also said the cooperation fitted a broader US foreign-policy priority of working with trusted partners to widen access to reliable energy technologies and strengthen energy security across the Indo-Pacific. The study is part of longer-term planning for a more diverse electricity system. EGAT said that, as demand for power is expected to keep increasing, SMR technology could strengthen the flexibility and security of the national grid while supporting economic growth and industrial development. Narin said Thailand was at a critical point in its clean-energy transition and needed to explore options that could reinforce energy security while ensuring stable generation. He described the US support as an important basis for assessing whether SMR technology was feasible, adding that EGAT valued the opportunity to learn from US expertise and experience.
