Thailand’s Electricity Generating Authority (EGAT) has accelerated its nuclear energy study, targeting commercial operation of the country’s first 300 MW small modular reactor (SMR) by 2037. The project forms part of the 2026 Power Development Plan and is intended to strengthen energy security, provide low-carbon electricity and reduce exposure to volatile global liquefied natural gas prices. EGAT has begun a pre-feasibility study to assess potential reactor technologies and construction sites, with capital expenditure estimated at THB60 billion–70 billion. The agency is working with the International Atomic Energy Agency (IAEA) to align technology selection, safety standards and regulatory frameworks with international practices.
The Eastern Economic Corridor is under preliminary consideration as a potential site because of its substantial industrial electricity demand. Final site selection will depend on consultant recommendations and environmental risk assessments, including assessments of seismic stability and cooling-water availability. Egat also plans to propose a dedicated Nuclear Energy Programme Implementing Organisation to oversee programme development in coordination with relevant government agencies. The authority is targeting total nuclear generation capacity of 9,000 MW by 2050, with SMRs expected to provide continuous electricity for industrial demand, data centres and electric vehicle infrastructure. Public engagement and the development of institutional and regulatory capabilities remain important elements of the programme.
