Summary
- Thailand has asked 49 data centre projects under construction to co-operate with a temporary pause; officials said they lack legal power to suspend those builds.
- A further 117 projects under review have had approvals frozen while national standards are developed.
- Four policy workstreams are examining economic value, infrastructure, sites and planning, and environmental requirements.
Thailand’s government has asked developers of 49 data centres already under construction to co-operate with a temporary pause while authorities prepare national rules governing the sector.
A further 117 projects awaiting approval have been frozen during the review. The distinction is important: Thai officials told AFP that the government does not currently have the legal power to suspend construction on the 49 projects and has instead asked developers for voluntary co-operation.
The intervention follows the first meeting of Thailand’s Data Center Business Policy Committee on 4 September. The government wants a national framework to replace a fragmented process in which developers separately approach agencies responsible for investment promotion, power, water, construction, and planning.
Authorities have created four workstreams covering economic value, infrastructure, land and urban planning, and environmental impacts. The infrastructure group includes electricity, water, and digital systems.
The committee is expected to develop clearer national requirements over the coming weeks. Existing operating sites, projects under construction, and pending applications are also being brought into a central government dataset intended to show their status alongside grid, water, planning, and legal information.
The review follows rapid investment growth and concerns that some facilities may have progressed through approval routes not designed specifically for data centres. The Thai government has cited gaps involving building use, backup-fuel storage, safety, environmental controls, and infrastructure demand.
A case in Bangkok sharpened those concerns shortly before the committee met. Authorities said around 200,000 litres of fuel had been stored without the necessary permission at a data centre site and was subsequently removed.
Power planning is a broader concern. Large data centres can request hundreds of megawatts each, requiring generation, transmission, substations, and network reinforcement long before the facilities become operational.
Thailand has already moved towards requiring greater proof that developers are ready to proceed before the electricity system commits capital to new infrastructure. Government policy has included proposals for financial guarantees linked to network use and water-management plans for large projects.
Water is being assessed alongside electricity because cooling design can materially alter a facility’s local resource demand. Evaporative cooling, closed-loop liquid systems, and other thermal architectures can produce very different water profiles even for facilities with similar IT loads.
The government also wants data centre investment to create more domestic economic value through employment, skills, technology transfer, local suppliers, and digital services.
That policy direction reflects the gap between headline investment figures and the permanent economic footprint of a highly automated facility. Data centres can require billions in capital and enormous utility connections while supporting relatively modest operating workforces compared with other industrial developments.
The request for existing construction projects to pause introduces immediate delivery risk even though it is voluntary. Equipment procurement, customer commitments, contractor schedules, and power-delivery programmes are all sensitive to changes in the expected completion date.
Developers will therefore need clarity on how the eventual rules apply to projects that already hold some permits or investment approvals. Retrospective design changes involving fuel systems, water infrastructure, power architecture, or site planning could be more expensive than applying new rules to undeveloped projects.
Thailand remains interested in attracting cloud and AI infrastructure rather than imposing a general moratorium. The government has repeatedly framed the exercise as an attempt to establish clearer standards and retain greater national benefit from investment.
The next stage is the detailed regulatory framework. Its treatment of the 49 projects already being built will be as important as the rules applied to the 117 developments still awaiting approval.
