Summary
- Thailand is targeting mid-October for a national regulatory framework covering data centre size, location, electricity use, and oversight.
- A proposed threshold would classify facilities using 100MW or more as hyperscale, although the figure has not yet been finalised.
- Industrial-classified projects could be restricted to designated estates, while the Energy Ministry is expected to determine electricity-use limits.
Thailand is considering a 100MW electricity-use threshold for hyperscale data centres as it prepares a national regulatory framework covering facility size, location, power consumption, and oversight.
The Office of the National Economic and Social Development Council expects the new framework to be ready by mid-October, according to secretary-general Danucha Pichayanan, who also serves as secretary of the committee overseeing data centre policy.
Danucha said a preliminary proposal would classify facilities consuming 100MW or more as hyperscale data centres. The threshold has not been finalised and remains subject to consideration by the policy committee.
The emerging rules would also address where different classes of facility can be built. Data centres falling within the definition of industrial operations could be required to locate in designated industrial estates, placing land use and infrastructure availability more directly into the national approval process.
Electricity limits will be determined separately by Thailand’s Energy Ministry. Danucha said a dedicated electricity tariff for the data centre sector already exists, while officials are gathering information on current operators, project sizes, and typical electricity and water consumption before settling the wider rules.
The latest detail moves Thailand’s regulatory review beyond the broad controls announced earlier this month. DataCentral reported on 8 September that officials had asked developers of 49 projects under construction to pause voluntarily and frozen decisions on 117 applications while national criteria were being prepared.
The 100MW proposal begins to put numbers around that process. Rather than treating every facility through the same framework, the government is moving towards rules differentiated by scale, resource demand, and location.
That distinction is significant for infrastructure planning because a 100MW data centre is already a major industrial electricity load. Facilities above that point can require dedicated substations, transmission reinforcement, new generation arrangements, or staged connection programmes, depending on the local network.
The actual effect will depend on how Thailand defines electricity use. A threshold could refer to contracted connection capacity, maximum demand, IT load, total facility demand, or another measure. Those definitions produce materially different outcomes for developers and utilities, and the available reporting does not yet establish which basis the committee will adopt.
The same uncertainty applies to the proposed industrial-estate requirement. Large campuses frequently depend on access to high-voltage electricity, fibre, water, road infrastructure, and enough land for generators, cooling plant, substations, and future phases. Directing projects towards industrial estates could concentrate those requirements in locations already intended for heavy infrastructure, but it may also narrow the pool of viable sites.
Thailand has attracted substantial data centre investment as cloud and AI providers expand across Southeast Asia. That growth has increased pressure on a regulatory system in which developers have historically dealt with different ministries and agencies separately rather than through a single national data centre framework.
The government established its Data Center Business Policy Committee to bring those approvals into a more coordinated system. Agencies were asked after the committee’s first meeting on 4 September to compile information on operating facilities, projects in development, infrastructure requirements, economic benefits, resource use, and environmental effects.
The resulting policy is intended to address more than planning permission. Officials are examining electricity and water consumption, project classification, location, economic contribution, environmental standards, and the mechanism through which different government bodies make approval decisions.
Danucha said the lead agency for the eventual system has not yet been determined, highlighting one of the practical issues the review is intended to resolve. A data centre can touch energy regulation, telecommunications, investment promotion, industrial policy, planning, environmental controls, and local infrastructure, leaving developers exposed to overlapping requirements if responsibilities are not clearly divided.
Power is likely to remain the hardest constraint. The rapid addition of very large loads requires utilities to distinguish projects with credible financing and delivery plans from speculative requests that could reserve network capacity without being built.
Thailand has already changed the energy-screening process for data centre investment during 2026. The latest national framework would go further by setting common expectations across project size, siting, resource demand, and approvals.
The proposed 100MW threshold should therefore be treated as a working figure rather than an adopted standard. Its importance lies in the direction of policy: Thailand is moving from broadly welcoming data centre investment towards a system that differentiates projects according to the physical demands they place on the power system and surrounding infrastructure.
Developers should get a clearer view of that system by mid-October if the government maintains its current timetable. Until then, the threshold, electricity limits, industrial-estate requirements, and final division of regulatory responsibility remain under consideration.
