Summary

  • NTT Global Data Centers (Thailand) Limited operates a portfolio anchored on BKK1 in Bangkok and BKK2/BKK3 at the Amata City Chonburi industrial estate, roughly 57km from central Bangkok in the Eastern Economic Corridor, with BKK4 and BKK5 now in the pipeline at the same campus.
  • Two conflicting sets of BKK2/BKK3 capacity figures exist in public sources: operator collateral lists 5MW of client IT load for BKK2 and 14MW at full buildout for BKK3, while DatacenterDynamics has reported 3.6MW and 12MW respectively.
  • BKK3's timeline slipped: announced in March 2023 with operations targeted for the second half of 2024, its planned service date later moved to the second half of 2025, and no public document confirms its actual commissioning date.
  • The strongest forward commitment is a 100MW power purchase agreement with B.Grimm Power signed in January 2026 for Bangkok 4, with energization expected in Q2 2027 and groundbreaking in July 2026 — but the 100MW figure is contracted power, not IT load.
  • Bangkok 5 exists only as a land purchase agreement with Amata Corporation, secured in February 2026, with no capacity, investment or schedule figures disclosed.

NTT Global Data Centers (Thailand) Limited is the kind of company whose growth is easy to quantify and hard to verify. It appears in APNIC registry records as a number-resource holder, and its leadership is named in operator materials: Suthipat Lueprasert as CEO of NTT Global Data Centers (Thailand) Limited and Takeshi Kimura as managing director of NTT Global Data Centers Holding Asia. https://services.global.ntt/en-us/services-and-products/global-data-centers/global-locations/asia-pacific/bangkok-data-centers But the substance of its expansion — how much IT capacity is actually commissioned in Thailand — has to be assembled from operator marketing collateral, trade press and a handful of corporate press releases, and those sources do not fully agree with each other.

The Bangkok portfolio begins with BKK1, located in the Bangkok metropolitan area. The operator's own location page for Bangkok frames the expansion as part of an ongoing growth strategy and emphasizes that the sites sit in areas with low natural-disaster risk and are within close distance of the city. That framing matters less for what it asserts than for what it omits: no megawatt figures appear on the overview page at all.

The first hard numbers come from BKK2, at Amata City Chonburi. NTT's Bangkok brochure describes it as Thailand's first purpose-built data center and the first in the country to receive TIA-942-C Facility Certification at Rated-3 level, with 9,600 m2 of total floor area, roughly 1,500 racks, 5,000 m2 of IT space, 9.5MVA of dual-path power receiving, and 5MW of client IT load in a 2N configuration. https://services.global.ntt/-/media/ntt/global/insights-and-resources/brochures/brochure-bangkok-data-centers-en.pdf?rev=177f605e41454db58200a293539a5df4 DatacenterDynamics, however, has described BKK2 as 3.6MW across 3,800 sqm. https://www.datacenterdynamics.com/en/news/ntt-signs-100mw-ppa-with-bgrimm-power-in-bangkok-thailand/ The difference — 5MW versus 3.6MW — is material, and no public document reconciles it. The plausible reading is that the operator figure reflects a later buildout state or a different measurement basis, but that is interpretation, not fact.

BKK3 sits adjacent to BKK2 in the same industrial estate. It was announced in March 2023 with an investment of THB 3 billion (about USD 90 million) — the only per-project capital figure in the public record for NTT Thailand — initially specified at 12MW of maximum IT capacity across approximately 4,000 m2, supporting racks up to 30kW, with operations targeted for the second half of 2024. https://services.global.ntt/en-us/newsroom/ntt-constructs-a-new-data-center-in-bangkok-thailand That date passed. NTT's current product page and brochure now list BKK3 at 14MW once fully built out, 4,000 m2 of IT space, support for racks up to 40kW, and a planned service date in the second half of 2025. https://services.global.ntt/en-us/services-and-products/global-data-centers/global-locations/asia-pacific/bangkok-3-data-center Two things changed between the announcement and the current collateral: the capacity metric was restated upward, and the timeline slipped by at least a year. Neither change is explained anywhere in the public record, and whether the second-half-2025 service date was met is not publicly confirmed.

Bangkok 4 is where the forward commitments get concrete. In January 2026, NTT signed a 100MW power purchase agreement with B.Grimm Power, via subsidiary Amata B.Grimm Power, to power the upcoming data center at the Chonburi campus, with energization expected in Q2 2027. https://www.linkedin.com/feed/update/urn:li:activity:7420148318112182272 Groundbreaking occurred in the week before 13 July 2026, announced via LinkedIn, with Fuji Electric named as builder of the campus substation. https://www.datacenterdynamics.com/en/news/ntt-breaks-ground-on-campus-in-chonburi-thailand/ This is the clearest evidence that construction has actually started — but the 100MW figure is contracted electrical power, not IT load, and the ratio between the two in real facilities typically runs well below one-to-one on delivered IT capacity. No IT-load figure for BKK4 exists in the public record, and no per-project capital figure for it has been disclosed.

Bangkok 5 is thinner still. In February 2026, NTT announced it had secured a land purchase agreement with Amata Corporation Public Company Limited for land in the Chonburi area. Full details had not been shared at the time of reporting: no capacity, no investment figure, no schedule. https://www.datacenterdynamics.com/en/news/ntt-buys-land-in-bangkok-thailand-for-new-data-center/

The market context gives the expansion its rationale. BMI research, reported by TechNode Global in June 2026, projects Thailand's data center capacity to quadruple as hyperscalers drive growth. https://technode.global/2026/06/23/thailand-data-center-capacity-set-to-quadruple-as-hyperscalers-drive-growth-bmi/ Data Center Map counts 44 operational facilities across 13 operators in Bangkok. B.Grimm, which already powers BKK2 and BKK3, said in 2024 it planned to spend 5–7 billion baht (about USD 145–203 million) expanding into the data center power market. At the corporate level, NTT says it operates more than 160 data centers in over 20 countries and regions, and CEO Doug Adams said in March 2026 that the company was working to double its capacity to 4GW in as little as two years — a corporate-wide ambition, not a Thailand-specific target. https://services.global.ntt/en-us/newsroom/ntt-data-lands-hyperscale-agreements-totaling-over-130mw-across-four-campuses

What does all this add up to? The dated, verifiable operational anchors are the operator's own certification claim for BKK2 and its specification tables; everything beyond that is either announcement (the PPA, the groundbreaking, the land purchase), restatement (BKK3's moving capacity figure and service date), or market projection (BMI's quadrupling). For buyers and investors in the Thai market, the distinction matters: a 100MW PPA tells you power has been contracted, not that servers are running; a full-buildout figure tells you what a site could hold, not what it holds today. The public record currently supports a Thailand portfolio whose confirmed operating base is measured in single-digit megawatts per site, with the multi-hundred-megawatt expansion still in front of it — and with the gap between those two states documented more clearly in the sources' disagreements than in any single figure.
