Thailand Cabinet Approves Seven-Tier Data Center Rules Amid 30,000MW Requests

Thailand's Cabinet approved a new regulatory framework for data centers on Nov. 10, replacing fragmented approvals with a seven-tier system keyed to power consumption. The framework covers facilities drawing 0.5 MW or more and adds screening, zoning and environmental standards to a market where more than 110 applicants have requested over 30,000 MW. The rules are Thailand's first industry-specific data center regulation, Nikkei Asia reported.

The seven bands run from below 0.5 MW to 200 MW and above. Facilities below 0.5 MW, typically internal server rooms run by banks and other organizations, stay outside the framework. Requirements tighten as size increases.

Projects under 20 MW may sit in commercial zones. Projects at 20 MW and above must be in industrial areas or industrial estates. Danucha Pichayanan, secretary-general of the National Economic and Social Development Council, reported overlapping electricity requests from more than 110 applicants totaling over 30,000 MW. Danucha estimated only about a quarter or fewer are genuine investors, with brokers and engineering, procurement and construction contractors reserving capacity in advance.

A screening committee and financial security requirements will filter applicants. The Ministry of Digital Economy and Society will run a Data Center One Stop SerFeatured: Aerial view of an operational data center facility in the greater Bangkok area subject to Thailand's tiered guidelines.vice to coordinate approvals, and a Data Center Dashboard will list projects and their locations.

An environmental code of practice caps backup-generator noise at 70 decibels at a facility's boundary and limits heat-driven temperature increases nearby to 1 to 2 degrees Celsius. Operators must recirculate cooling water and test it before discharge. Data centers generally will not need individual environmental impact assessments because they house servers, though projects in industrial estates fall under the estates' assessments.

"The use of national resources must not adversely affect the public," said Ekniti Nitithanprapas, deputy prime minister and finance minister and chair of the Data Centre Operations Policy Committee, at a news conference. Ekniti listed three priorities for the framework: clearer and more transparent rules, allowing lawful operators to continue during the transition, and future investments that maximize benefits for Thailand. Ekniti described data centers as essential infrastructure for the digital economy and AI but said their electricity and water requirements could affect communities.

Projects holding construction permits or Board of Investment promotion granted before Aug. 14, 2026 may proceed with about one year to meet the new standards. Applications filed after that date, and all new projects, must clear an economic-value assessment by the screening committee before the Board of Investment, utilities and permit authorities act.

Narit Therdsteerasukdi, secretary-general of the Board of Investment, said the agency has granted promotion to 57 data center projects. Seventeen are operating, 20 hold construction permits and are being built, and 20 are preparing to invest.

Thailand suspended construction on 49 data center projects and froze approvals for 117 more in September while it drafted the rules, Baxtel reported at the time.

Baxtel tracks 97 data center facilities in Thailand, led by True IDC with 11 sites and Digital Edge DC with 3. The largest is STT Bangkok 1 at 23 MW, and 19 facilities are under construction in Bangkok.

Narit said all approved projects will enter the one-stop service system for review against environmental standards. The ministry will set up that service and the dashboard to screen projects and coordinate approvals.
