DayOne Singapore (21 Jalan Buroh) is a data center project in Singapore, operated by DayOne (ex-GDS International). It is under construction. It is planned for 20 MW of IT load.
Latest change on record: entered the record as under construction on 25 July 2025. Record last checked against its sources on 21 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 Singapore approves, powers and taxes data centers is on Data center rules in Singapore.
Singapore holds 39 active projects with 874 MW of planned IT load between them, and DayOne Singapore (21 Jalan Buroh) ranks 17th by planned capacity. Of those, 27 are operational, 3 are operational and expanding, 3 are under construction, 1 is past financial close and 5 are announced only. Published colocation vacancy in Singapore was 4.9% as of December 2025, on 1,043 MW of operational colocation capacity as counted by Cushman & Wakefield. Vacancy excludes hyperscaler self-build.
DayOne has 8 projects elsewhere in the dataset tracked by ArusGrid, including DayOne Kabil Industrial Tech Park (KITP), DayOne Chonburi Tech Park (CTP1) and DayOne Nongsa Digital Park Campus (NDP1-3). Named funding comes from Hillhouse Investment on the equity side. No tenant has been disclosed, which is normal for colocation and says nothing about occupancy.
The stage was recorded as under construction on 25 July 2025. The money on record is S$112.8m (about US$84m) as of January 2024, the announced investment. Power comes from Sembcorp through a renewable power purchase agreement. Cooling uses hybrid air and liquid cooling.
Grid power for a large industrial user in Singapore costs about US$0.20 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 Singapore, as of 27 September 2026, is recorded as “No US destination-based licence requirement as enforced”. ArusGrid holds 8 public sources for this project, the latest dated 30 July 2025, and last checked the record on 21 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.
hybrid air+liquid cooling
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.

No tenant disclosed. Most colocation leases are confidential, so this says nothing about occupancy. Not yet checked against second-order sources.
The figure covers land only.
Platform capital spans several sites. It is never added to this project's own figure.
The published band for Singapore is too wide to say anything useful about this building (range wider than half its midpoint, withheld), so no estimate is shown. The band itself is on the Colo prices page.
