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 Haoyang Data Center 1 (WHA ESIE 4, Rayong) ranks third 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 Beijing Haoyang project ArusGrid tracks. Named funding comes from Beijing Haoyang Cloud & Data Technology and Apollo Global Management 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 at the land and permitting stage on 11 June 2025. The money on record is THB 72.67bn (about US$2.2bn) as of March 2025, a government approval ceiling.
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 7 public sources for this project, the latest dated 12 June 2025, 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.
300MW modern greenfield (largest single approved IT load in Thailand); sponsor runs 360MW of Chinese hyperscale capacity and is Apollo-backed. No cooling/density disclosure.
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.

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.
An approval figure is an incentive ceiling. It often covers a first phase and can exclude land or IT equipment.
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.
