Johor has become one of Asia’s fastest-growing AI data centre hubs. This door follows who gets paid across TNB, YTL Power, AirTrunk and the builders, why grid delivery is the stuck step, and the dates that matter. Education only, not investment advice.
Malaysia is the AI data centre build-out door, led by Johor. Land is cheaper, power is available, and submarine cables are close. As at March 2026, TNB had secured 59 data centre projects with 8.3 GW of maximum demand; 36 projects (4.5 GW) were connected, and actual load was 1,054 MW, more than double a year earlier (iFAST Research via The Malaysian Reserve, Aug 2026).
AirTrunk is building more than 700 MW across four Johor campuses and closed a US$2.325 billion green loan for JHB2 on 29 July 2026 (AirTrunk). YTL Power has 300 MW secured at Kulai, 150 MW operating, and land for up to 2.4 GW in total (The Star, 7 Oct 2026). For the layer map, read AI Data Centers.
As at October 2026, the stuck step is grid delivery: substations and connections decide which projects move on schedule (Business Times).
| Step | Who | How they get paid | Status (Oct 2026) |
|---|---|---|---|
| Grid | TNB | Regulated grid returns; power sales | 8.3 GW secured; 4.5 GW connected; 1,054 MW actual load (Mar 2026) |
| Hyperscale landlord | AirTrunk (Blackstone) | Long hyperscale leases | 700+ MW across four Johor campuses; JHB1–2 almost fully contracted |
| Listed developer | YTL Power | Lease income; AI-GPU capacity | 300 MW secured, 150 MW operating at Kulai |
| Builders | Gamuda, IJM and others | Construction contracts | Awards rising as projects reach build |
Status is Second Order’s read from TNB data cited by iFAST Research, AirTrunk releases and The Star.
| Name | What they do | Which step |
|---|---|---|
| Tenaga Nasional (TNB) | National grid and utility | Power / grid |
| YTL Power | Kulai data centre park; Nvidia-based AI cloud | Developer / operator |
| AirTrunk | Blackstone-owned hyperscale platform (unlisted) | Landlord |
| Gamuda, IJM | Contractors on data centre builds | Builder |
Examples of exposure roles only — not recommendations.
| Date | Event | What to look for |
|---|---|---|
| Quarterly | TNB data centre pipeline updates | Whether actual load keeps pace with connected capacity |
| Open | AirTrunk JHB3 and JHB4 | Build progress on the extra 280+ MW |
| 2027 | YTL Power planned data centre IPO (per HLIB Research) | Funding for the 2.4 GW pipeline |
Johor has become one of Asia’s fastest-growing data centre hubs. TNB had 8.3 GW of data centre demand secured across 59 projects at March 2026, with 1,054 MW of actual load.
Grid delivery. Substations and connections, not power generation, decide which projects open on time.
YTL Power (Kulai data centre park), TNB (the grid), and builders such as Gamuda and IJM. AirTrunk is a large private landlord in Johor.
No. This door maps who gets paid and which step is stuck. It is education only.
