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.
Construction or financing is evidenced, or several independent signals agree. On record: named funder, three or more sources, dated source in the last 24 months. Criteria.
AI workloads
StatusLikely
100MW of contracted power for a single new building, 2026-27 vintage, from an operator whose current builds are liquid-cooling-ready. No cooling/density spec published for BKK4 specifically.
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.
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.
