AirTrunk JHB1 is a data center project in Iskandar Puteri, Malaysia, operated by AirTrunk. It is operational and expanding. It is planned for 150 MW of IT load. The operator reports 50 MW running.
Latest change on record: moved to expanding on 30 July 2024. Record last checked against its sources on 18 October 2026.
This project is built or running, so every gate counts as passed.
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 Malaysia approves, powers and taxes data centers is on Data center rules in Malaysia.
Johor holds 43 active projects with 4,880 MW of planned IT load between them, and AirTrunk JHB1 ranks 14th by planned capacity. Of those, 3 are operational, 9 are operational and expanding, 11 are under construction, 1 is past financial close, 5 are at the land and permitting stage and 14 are announced only. Published colocation vacancy in Johor was 0.7% as of June 2026, on 897 MW of operational colocation capacity as counted by Cushman & Wakefield. Vacancy excludes hyperscaler self-build.
AirTrunk has 3 others in Malaysia and 8 projects elsewhere in the dataset tracked by ArusGrid, including AirTrunk JHB2, AirTrunk JHB4 and AirTrunk JHB3. It sits on the AirTrunk JHB1 campus. Named funding comes from Blackstone and CPP Investments on the equity side. The named user of the compute is ByteDance (reported, unconfirmed).
The build is phased. Initial phases at 50 MW is operational with a 2024 target; Full build (20 halls) at 150 MW is under construction. The dated record runs from under construction in 2023 to operational and expanding on 30 July 2024. The money on record is RM9.7bn (about US$2.2bn) as of February 2025, the announced investment. Power comes from Pekat Solar (Pekat Group, Bursa) through onsite solar. Cooling uses direct liquid cooling and reclaimed water from Johor Special Water (IWK treated effluent), with a design PUE of 1.15.
Grid power for a large industrial user in Malaysia costs about US$0.14 per kWh as of July 2025, the country figure ArusGrid applies where a site has no published rate. The US export control position for advanced AI chips in Malaysia, 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 15 July 2026, and last checked the record on 18 October 2026.
Running capacity. The site is operational or expanding. The rules are fixed and published on the Methodology page.

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.

W.Media, citing the Australian Financial Review's report that Blackstone is weighing a sale of JHB1, states 'JHB1 was opened last year and currently hosts several big-name customers including TikTok owner ByteDance'. Press, unnamed sources, so stays reported.

The figure covers several facilities.
Platform capital spans several sites. It is never added to this project's own figure.
No published price band exists for Malaysia, and ArusGrid does not estimate from the regional benchmark alone. What was searched is listed on the Colo prices page.
