Your call. Will it be built?
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.
Thailand, 2026-09-24. Thailand asked developers on 4 September 2026 to pause 49 data centres under construction and froze 117 pending approvals while it writes new rules, due by mid October. The government has said it cannot legally enforce the pause. No list of affected projects has been published, so no Thai project has changed stage on this basis. A separate data centre electricity tariff has been created with no rate set.
EEC (Eastern Seaboard) holds 21 active projects with 3,703 MW of planned IT load between them, and Galaxy Data Center (Silicon Tech Park, Rayong) ranks second 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.
It is the only Galaxy DC project ArusGrid tracks. It sits on the Silicon Tech Park (Ban Chang, Rayong). Named funding comes from Galaxy Data Center 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 stage was recorded as under construction on 25 September 2026. The money on record is US$2,000m as of September 2025, the announced investment. Power comes from Galaxy Data Center with Silicon Tech Park through onsite solar (reported, unconfirmed).
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 11 public sources for this project, the latest dated 25 September 2026, and last checked the record on 22 October 2026.
How well evidenced is it
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.

AI workloads
StatusLikely
Explicitly described as a large-scale computing cluster for advanced AI workloads; 150MW greenfield.
Access to AI chips
GradeNo US licence required
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.
US licence required for this destination as enforcedNo
A party headquartered in China or Macau on the projectNo

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.

Approx. 65% of water is raw water from private suppliers; remaining ~35% is treated municipal tap water (see separate fact). Operator says WUE will be publicly disclosed.
WaterMains drinking water · Provincial Waterworks Authority (PWA), Ban Chang Branch Reportedsource ↗
Planned supply is about 35% PWA tap water and 65% raw water from a private supplier, with a dry season backup plan. The developer is funding over 37 million baht for PWA Ban Chang to extend distribution and lay pipes to the site. It says it will disclose actual water use and WUE.

The project gave more than THB37 million to PWA Ban Chang to upgrade water distribution and lay a supply pipe to the site. It has a dry season backup plan and says it will publish actual water use and WUE.
Planned MW is IT load, the power available to servers, unless marked otherwise. Running capacity is rarely published, so a missing figure means undisclosed.
