I. Core Requirements of the New DBD Regulations

Thailand remains one of Southeast Asia’s most active markets for new data center investment, but the regulatory direction is changing. On 5 August 2026, the Cabinet approved the establishment of a national Data Center Business Policy Committee. The Committee is intended to coordinate policy, standards and agency-level approaches for data center approvals, investment promotion and related services, with particular attention to economic benefit, energy security, water availability and environmental impact.

The direction became clearer at the Committee’s first meeting on 4 September 2026: Thailand is not closing the door to data center investment, but it is moving from fragmented project-by-project consideration toward a national framework that asks what types of data centers Thailand needs and what benefits they should deliver. For investors, this makes regulatory strategy, power planning and demonstrable benefits to Thailand increasingly important at the earliest stage of project development.

1. Investment Is Growing Rapidly – but Power Readiness Is Critical

BOI data published in August 2026 shows that 42 data center projects approved for investment promotion during 2024-2026 represent approximately THB 750 billion in investment and a combined IT load of about 3,400 MW. This is a more accurate measure of the current investment pipeline than describing Thailand as having 42 operational data centers: the 42 figure refers to BOI-promoted projects, not necessarily facilities already in operation.

Electricity availability is consequently becoming a central project-development issue. EGAT is expanding transmission capacity in the Eastern Economic Corridor (EEC), including urgent upgrades designed to accommodate approximately 1,150 MW of additional large-user demand. Government policy is also moving toward making data center users bear an appropriate share of the additional infrastructure and power-system costs created by large loads.

2. A New National Data Center Policy Framework Recommendations

The Data Center Business Policy Committee is a national-level body chaired at deputy-prime-minister level, with the BOI and other relevant authorities participating. Its role is broader than BOI investment promotion: it is intended to develop national policy, standards and common guidelines for authorities involved in licensing, approvals, investment promotion and the provision of infrastructure and services to data center operators.

The framework is still developing. Government statements in September 2026 indicate that agencies are working on common rules, data-center classifications, infrastructure information and assessment criteria. Investors should therefore distinguish between measures already in force and policy directions that are still being developed.

3. BOI Incentives: Location, Efficiency and Benefits to Thailand Matter

BOI promotion remains an important route for foreign investors because promoted projects may receive both tax and non-tax incentives, including relief from certain foreign ownership restrictions. The BOI has progressively tightened the conditions applicable to data center projects.

Under the revised BOI framework, corporate income tax exemption periods vary by project characteristics and location. BOI materials indicate a range of three to five years for qualifying projects in the EEC and five to eight years outside the EEC. The highest level of tax benefits is associated with projects meeting enhanced requirements, including energy-efficiency standards and, for the relevant category, advanced computing capabilities. A PUE of no more than 1.3 is a key benchmark for high-energy-efficiency data center projects.

Additional conditions include:

• a plan demonstrating benefits to Thailand, including areas such as workforce development, technology or knowledge transfer and local economic contribution;
• for projects employing executives and professionals, Thai nationals must account for at least 50% of those positions within three years; and
• under BOI Announcement No. Sor. 2/2569, relevant data center projects must obtain an electricity-supply confirmation from the Office of the Energy Regulatory Commission before submitting the BOI application.

The practical implication is significant: site selection, grid capacity and the proposed electricity-sourcing strategy should be assessed before, rather than after, the BOI application is prepared.

4. Four Areas of Increasing Regulatory Scrutiny

The BOI has identified at least four dimensions that are expected to inform the evolving national screening framework. These should presently be viewed as the direction of regulatory development rather than as a fully settled four-part statutory test:

• Benefits to Thailand – including skilled employment, workforce development, Thai vendors and SMEs, technology development, R&D and contribution to Thailand’s AI and digital ecosystem.
• Energy readiness and security – including generation and transmission capacity, energy efficiency, clean-energy use and responsibility for infrastructure costs.
• Water availability and efficiency – including water sources, cooling technology, recycling, drought resilience and potential differentiated water pricing.
• Environmental and community impact – including land-use planning, fire safety, heat, noise, wastewater and lifecycle impacts on surrounding communities.

The BOI has also stated that relevant authorities are developing nationwide power- and water-capacity maps to support future planning and possible zoning decisions.

5. Energy and Water Strategy: Plan Early

Thailand’s energy policy for data centers is developing quickly. In July 2026, the National Energy Policy Council approved measures including a separate electricity-user category for data centers, financial security requirements connected with grid use, and further development of renewable-energy procurement through Direct PPA arrangements using third-party access to the grid. The government has also asked regulators to clarify rules supporting self-generation and Independent Power Supply arrangements.

Water is receiving similar attention. Current policy discussions cover water-source availability, cooling technology, recycling, drought management and the possibility of higher or differentiated tariffs for intensive users. It would therefore be premature to state that a universal tiered water tariff or a general mandatory water-reporting regime for all data centers is already in force. These matters remain part of the developing regulatory framework.

Likewise, there is no general rule presently requiring data center investors to build their own generation facilities. Self-generation and direct renewable procurement are, however, becoming increasingly relevant options as Thailand seeks to accommodate very large new electricity loads without shifting disproportionate system costs to other users.

6. What This Means for Investors

Thailand remains open to data center investment, but the policy emphasis is moving toward quality, infrastructure readiness and measurable national benefit. For new projects, the regulatory workstream should therefore begin alongside the commercial and technical workstreams – not after the site and investment structure have already been fixed.

In practice, investors should address at an early stage:

• BOI eligibility, incentive category and foreign-ownership structure;
• site selection and available grid capacity;
• electricity-supply confirmation and the sequencing of the BOI application;
• PUE and other technical requirements;
• renewable-energy procurement and potential Direct PPA or self-generation options;
• water sourcing, cooling and recycling strategy;
• Thai employment, training, R&D and local-supply-chain commitments; and
• land-use, environmental, construction and operating permits applicable to the specific project and location.

The central message is not that Thailand is becoming closed to data center investment. Rather, investors should expect greater coordination among regulators and closer scrutiny of how a project uses scarce infrastructure and what lasting value it creates for Thailand.

How We Can Help

BRS&S advises investors and operators throughout the lifecycle of data center projects in Thailand, from investment structuring and BOI promotion through establishment, licensing and project implementation. Our work includes foreign ownership and corporate structuring, BOI applications, regulatory and permitting strategy, IEAT and factory-related approvals where applicable, and the review and negotiation of EPC, power, water, land and other project agreements.

Given the pace of regulatory development, we also assist clients in assessing how changes in Thailand’s data center, energy and infrastructure policies may affect project feasibility, sequencing and ongoing compliance.

Sources and Verification Note

This update reflects publicly available information reviewed as of 26 September 2026, including publications of the Thailand Board of Investment, the Royal Thai Government, the Electricity Generating Authority of Thailand and public materials concerning the evolving Direct PPA framework. Several elements of Thailand’s new national data center framework remain under development. Project-specific advice should therefore be based on the rules and agency practice in force at the time of application.
