Thailand’s National Economic and Social Development Council is finalizing rules that would classify data centers using 100 megawatts or more of power as “hyperscale” facilities, with a target rollout by mid-October 2026. The framework follows a September 4 government decision to pause 166 pending data center projects while regulators work to align the country’s fast-growing digital investment pipeline with its electricity grid capacity.
Key Facts At A Glance
- Proposed hyperscale threshold: 100 megawatts (MW) or more of electricity demand
- New rules target mid-October 2026 implementation
- 166 data center projects paused on September 4, 2026, pending new standards (49 under construction, 117 awaiting permits)
- 26 companies held data center licenses from Thailand’s telecom regulator as of July 27, 2026, with combined declared demand exceeding 1,059 MW
- Three operators, Vistas Technology, Zenith Data Center, and Stratus Technology, account for roughly 660 MW, about 62 percent of licensed capacity
- Energy Minister Akanat Promphan estimated in July that data center and AI-related electricity demand could eventually reach 30,000 MW
- Board of Investment applications in the digital sector totaled THB873.7 billion across 48 projects in the first quarter of 2026
Thailand’s Board of Investment recorded a sharp jump in digital infrastructure applications in early 2026, with total investment applications exceeding THB1.01 trillion in the first quarter, about 2.4 times the amount recorded a year earlier. Data centers and cloud services made up the bulk of that figure, drawing interest from global technology firms alongside Chinese, Emirati, and regional developers. The scale of that buildout has put new strain on the country’s power system, prompting the government to intervene directly in how the sector is licensed and sited.
Pause And Policy Reset
The regulatory reset began on September 4, 2026, when Prime Minister Anutin Charnvirakul, chairing a newly formed data center policy board, ordered a temporary pause on 166 new projects and created four subcommittees tasked with drafting common standards within a month. Deputy Prime Minister and Finance Minister Ekniti Nitithanprapas, who led the September 4 meeting, identified consolidating industry data, setting minimum standards, and increasing the economic benefits Thailand receives from the investment as immediate priorities.
An earlier proposal had floated a 2 MW threshold for classifying data centers as industrial facilities, a figure officials at the meeting considered too low given the scale of projects already in the pipeline. NESDC Secretary-General Danucha Pichayanan said on September 15 that officials were working toward a roughly one-month timetable to clarify the regulatory framework and minimum standards, addressing resource use and effects on surrounding communities while limiting disruption to existing operators.
Hyperscale Threshold And Siting Rules
By September 20, Danucha said the framework had converged around classifying facilities using 100 MW or more as hyperscale, though the final threshold remains subject to the policy committee’s approval. Under the draft rules, data centers meeting the criteria for classification as industrial operations would be required to locate within designated industrial estates, with the stated aim of preventing adverse effects on residential areas. The Energy Ministry would separately set limits on electricity consumption for qualifying facilities.
Thailand’s telecommunications regulator, the NBTC, is also moving to reclassify data center licenses from a lighter Type 1 category to the more demanding Type 3 category, which would introduce zoning requirements, upfront checks on electricity and water supply contracts, mandatory separate utility systems, e-waste management obligations, and a local content requirement of at least 50 percent. As of late July, NBTC records showed 26 licensed operators with declared electricity demand topping 1,059 MW, concentrated among a handful of large developers with reported links to Chinese and other foreign parent companies.
Separately, Thai authorities have previously floated a preferential electricity tariff for large data centers, with an initial rate of five to six baht per kilowatt-hour under consideration against a general rate of 3.95 baht per unit for the September to December 2026 period, and discussed allowing the Electricity Generating Authority of Thailand to sell power directly to hyperscale facilities to ease pressure on lower-voltage distribution networks. Publicly available reporting has not yet confirmed whether these tariff and direct-supply proposals will be incorporated into the final framework expected in October.
