Thailand: Vendor-Neutral Small Modular Reactor Deployment Pre-Feasibility Study
October 30, 2026
- February 1, 2027
The Electricity Generating Authority of Thailand (“EGAT”) invites submission of qualifications and proposal data (collectively referred to as the “Proposal”) from interested U.S. firms that are qualified on the basis of experience and capability to execute a pre feasibility study for the proposed deployment of approximately 600 megawatts (“MW”) of small modular reactor (“SMR”) capacity. The Proposal submission deadline is Monday, February 1 at 12 a.m. Washington (EST) / 12 p.m. Bangkok (ICT). The U.S. firm selected will be paid in U.S. dollars from a $2,123,180 grant to EGAT from the U.S. Trade and Development Agency.
About the Grantee
EGAT was established in May 1969 as a Ministry of Finance -owned state enterprise utility under the supervision of the Ministry of Energy. As Thailand’s largest power producer, EGAT accounts for more than one-third of the country’s electricity generation and maintains exclusive control over the national high-voltage transmission system. EGAT owns and operates 53 power plants with a total generation capacity of 16,920 MW (as of 2025). EGAT also manages a nationwide transmission network that supplies electricity to every region of Thailand. With a proven record in developing and financing complex, large-scale infrastructure, EGAT has technical expertise and institutional capacity to lead the proposed Project.
Project Background
The Project involves the potential development of approximately 600 MW of SMR capacity in Thailand, as identified in Thailand’s proposed Power Development Plan (“PDP”). The current PDP framework contemplates deployment across two locations, with approximately 300 MW of capacity in southern Thailand and another approximately 300 MW in the northeastern region of the country. These regions were identified based on projected power system needs, including the need for additional baseload generation capacity in southern Thailand and growing requirements for grid stability and dispatchable generation support in the northeast, where significant variable renewable energy capacity is expected to be added over time.
The Project would be developed by EGAT, Thailand’s state-owned electric utility responsible for power generation and transmission across the country. Historically, EGAT has served as the lead developer for all new power generation technologies in Thailand prior to broader private sector participation. EGAT developed and operates Thailand’s first large-scale hydropower facilities, pioneered the country’s natural gas-fired generation sector, and led development of Thailand’s initial utility-scale renewable and high-efficiency thermal generation projects. Consistent with this role, EGAT is currently leading Thailand’s evaluation of potential civil nuclear deployment pathways and institutional readiness.
Thailand remains in the early stages of civil nuclear project preparation. Thailand has not selected a reactor vendor, technology provider, or specific project sites. While the pre-feasibility process is expected to evaluate a range of U.S. SMR technologies currently under development globally, EGAT has prioritized technologies considered capable of near-term deployment.
About the Study
The proposed USTDA-funded activity is a vendor-neutral pre-feasibility study to support EGAT’s evaluation of potential SMR deployment pathways in Thailand. Implemented over an approximately twelve-month period, the Study would assess the technical, economic, financial, regulatory, environmental, and institutional considerations associated with developing approximately 600 MW of SMR capacity in Thailand.
The Study would evaluate a range of U.S. SMR technologies and support EGAT in identifying reactor designs potentially suitable for deployment in Thailand based on factors such as technology readiness, licensing status, safety considerations, operational characteristics, and export applicability.
The Study would also assess potential deployment configurations, including alternative siting and multi-unit arrangements, to evaluate the most technically and economically suitable approach for Thailand’s future SMR program. In addition, the Study would evaluate site and grid integration considerations, financing and commercial structures, legal and regulatory readiness, institutional capacity requirements, project risks, and preliminary environmental and social impacts. The activity would further include an assessment of potential U.S. sources of supply and development of a project implementation roadmap identifying the steps necessary to advance toward future project development, procurement, licensing, and implementation.
