STT Bangkok 1 is a data center project in Hua Mak, Bang Kapi, Thailand, operated by ST Telemedia Global Data Centres (Thailand). It is operational. It is planned for 20 MW of IT load. The operator reports 20 MW running.
Latest change on record: moved to operational on 16 September 2021. Record last checked against its sources on 22 October 2026.
This project is built or running, so every gate counts as passed.
Build odds is ArusGrid's reading of the public record, not a forecast, a rating or advice. It counts the gates this project has passed in public sources. Private progress does not show, a passed gate can be undone, and projects that pass every gate still stop. The method has not yet been tested against outcomes. How it works.
How Thailand approves, powers and taxes data centers is on Data center rules in Thailand.
Bangkok metro holds 23 active projects with 893 MW of planned IT load between them, and STT Bangkok 1 ranks 15th by planned capacity. Of those, 6 are operational, 3 are operational and expanding, 5 are under construction, 2 are being commissioned, 3 are at the land and permitting stage and 4 are announced only. Published colocation vacancy in Bangkok metro was 22.1% as of June 2026, on 113 MW of operational colocation capacity as counted by Cushman & Wakefield. Vacancy excludes hyperscaler self-build.
STT GDC has 1 other in Thailand and 23 projects elsewhere in the dataset tracked by ArusGrid, including STT Bangkok 2. It sits on the STT Hua Mak campus alongside STT Bangkok 2. Named funding comes from KKR and Singtel on the equity side and Frasers Property. The named user of the compute is SIAM.AI Cloud (reported, unconfirmed).
The dated record runs from under construction in May 2019 to operational on 16 September 2021. Cooling uses direct liquid cooling, with a design PUE of 1.4.
Grid power for a large industrial user in Thailand costs about US$0.10 per kWh as of July 2026, the country figure ArusGrid applies where a site has no published rate. The US export control position for advanced AI chips in Thailand, as of 27 September 2026, is recorded as “No US destination-based licence requirement as enforced”. ArusGrid holds 6 public sources for this project, the latest dated 1 September 2026, and last checked the record on 22 October 2026.
Running capacity. The site is operational or expanding. The rules are fixed and published on the Methodology page.
Liquid cooling stated by STT GDC on 2025-10-22. Chilled water plant with cooling towers (N+1) plus direct-to-chip and immersion cooling (facility factsheet).
This country carries no US destination-based licence requirement for advanced AI chips as the rules are enforced today. Access is a commercial matter between the project and its vendors. Criteria are published on the Methodology page.

First NVIDIA GB200 NVL72 cluster; 48 NVL72 systems (about 3,500 GPUs) planned, two installed at announcement, full installation targeted mid-2025 · as of 2025-02-13
Siam AI and STT GDC Thailand announced jointly that Siam AI's first GB200 NVL72 cluster is installed at STT Bangkok 1 (Busrin Pradisthyont, STT GDC Thailand country head, quoted). Thai press puts the first 48 systems at about THB 7bn. This is a GPU cloud hosting its own fleet in STT's building, so it is a compute user rather than a hall lease.

Platform capital spans several sites. It is never added to this project's own figure.
No published price band exists for Thailand, and ArusGrid does not estimate from the regional benchmark alone. What was searched is listed on the Colo prices page.
