DayOne Chonburi Tech Park (CTP1) is a data center project in Amata City Chonburi, Thailand, operated by DayOne (GDS International). It is under construction. It is planned for 120 MW of IT load.
Latest change on record: entered the record as under construction on 17 March 2025. Record last checked against its sources on 22 October 2026.
Next gate to watch: Tenant or own use.
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.
EEC (Eastern Seaboard) holds 21 active projects with 3,703 MW of planned IT load between them, and DayOne Chonburi Tech Park (CTP1) ranks 9th by planned capacity. Of those, 2 are operational, 1 is operational and expanding, 9 are under construction, 7 are at the land and permitting stage and 2 are announced only. No third party publishes a colocation vacancy rate for EEC (Eastern Seaboard), and ArusGrid does not estimate one.
DayOne has 8 projects elsewhere in the dataset tracked by ArusGrid, including DayOne Kabil Industrial Tech Park (KITP), DayOne Nongsa Digital Park Campus (NDP1-3) and DayOne Singapore (21 Jalan Buroh). It sits on the Chonburi Tech Park. Named funding comes from GDS Holdings on the equity side. No user of the capacity is on the public record as of 2026-10-01, after a check of operator, landlord, contractor, regulator and lender documents. Most colocation leases are confidential, so this says nothing about occupancy.
The build is phased. Phase 1 is under construction with a 2026 target; Phase 2 is announced. The stage was recorded as under construction on 17 March 2025. The money on record is THB 28bn (about US$831m) as of March 2025, the announced investment. Power comes from Amata B.Grimm Renewable Energy Company Limited (AMBRE) through a renewable power purchase agreement at 22 kV. Cooling uses direct liquid cooling.
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 15 public sources for this project, the latest dated 5 October 2026, and last checked the record on 22 October 2026.
Construction or financing is evidenced, or several independent signals agree. The rules are fixed and published on the Methodology page.
Reaching this stage requires a dated construction source, which corroborates the project on its own.
Liquid cooling designed in campus-wide (DayOne PR, Mar 2025) and stated cloud/AI purpose; >100MW modern greenfield. No named AI tenant yet. Liquid cooling stated by w.media on 2025-03-18. Liquid cooling integration (campus-stated, type not detailed).
A party to this project (its operator, that operator's group, a funder, or a confirmed client) is headquartered in China or Macau or has an ultimate parent there. US rules require a licence for advanced AI chips destined to such entities wherever they are located. This describes the rule and says nothing about whether a licence was sought, granted or refused. Criteria are published on the Methodology page.

Checked on 2026-10-01. No user of this capacity is on the public record. ArusGrid read the operator's releases, the landlord's and contractors' exchange filings, regulator and lender documents and interconnection records. Most colocation leases are confidential, so this says nothing about occupancy.
The figure covers the whole campus.
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.
