Thailand Pauses 166 Data Center Projects to Rewrite the Rulebook

Thailand’s newly formed data centre policy board asked developers to pause 166 projects on September 4 — 49 already under construction and 117 awaiting permits — while four government subcommittees spend one month writing national standards for power, water, land and environmental use. Thirty-five operating facilities, including 11 with BOI investment promotion, are not affected.

What was actually decided

The board’s first meeting, chaired by Deputy Prime Minister and Finance Minister Ekniti Nitithanprapas, drew on data from 16 government agencies compiled by Danucha Pichayanan, secretary-general of the National Economic and Social Development Council (NESDC), according to Nation Thailand. The breakdown: 49 projects under construction and 117 pending agency approval — 166 combined — against 35 facilities already operating, of which 11 hold BOI promotion. Six Bangkok-area applications were singled out, with three already approved and operating and three placed on hold.

Four subcommittees now have until roughly early October to produce criteria: economic benefits (jobs, technology transfer, value assessment) under NESDC; infrastructure (water, electricity, digital networks) under the energy ministry’s permanent secretary; sites and buildings (locations, structures, fuel storage) under the interior ministry’s permanent secretary; and environment (green standards, inspection procedures) under the natural resources ministry. A new business category for data centres is also being created under the Department of Business Development, per Nation Thailand’s reporting.

Officials framed the trigger as capacity growing faster than the grid, water systems and Bangkok-area land can absorb without friction — one specific concern raised was a proposed facility’s diesel-storage plan running to roughly 500,000 liters. BOI Secretary-General Narit Therdsteerasukdi said clear rules would “strengthen long-term investor confidence” by letting developers understand costs and resource availability upfront. Ekniti indicated that future approvals may shift toward a competitive bidding process weighing which projects deliver the most benefit to Thailand — a departure from the largely first-come approvals that drove 2025’s investment wave.

Importantly, the pause is not a legal order. The government has said it has no statutory authority to halt construction outright and is asking developers to cooperate voluntarily until the new rules land.

What it means for buyers of power

Thailand has been the release valve for demand that Malaysia’s non-AI restrictions pushed south — BOI approved THB 746 billion in data centre investment in 2025 alone, and our Thailand market page tracks a pipeline still concentrated in Bangkok, Chonburi and the Eastern Economic Corridor. Bangkok itself carries no published benchmark yet on our colocation index — pricing there still moves deal by deal rather than off a rate card, per our market notes — which means the immediate effect of this pause will show up in delivery timelines before it shows up in headline rates.

For any buyer with a reservation or LOI tied to one of the 49 halted construction projects, expect at least a one-month slip, with real risk of longer if the subcommittees don’t finish on schedule or the new environmental and infrastructure standards require redesign. Conversely, the 35 already-operating facilities — the supply not touched by the pause — sit in a slightly better negotiating position for the next month or two, echoing what happened in Johor after Malaysia’s 2026 freeze: a near-term scarcity premium on ready-now space while the pipeline behind it stalls.

What we don’t know yet

The one-month subcommittee timeline is a target, not a deadline with enforcement behind it — the pause itself relies on voluntary compliance. It’s also unclear whether the new standards will raise construction costs (via stricter fuel-storage, water or environmental requirements) enough to move Thailand’s build-cost advantage over Malaysia, or how the three specific Bangkok projects placed on hold will be resolved. We’ll update our Thailand facility listings as individual projects clear the new review.
