150 MW campus launched 2024-07-30 with initial phases over 50 MW, 18 months after announcement; JHB2 (270 MW) follows, and JHB3-4 (280 MW, announced 2026-04-30) take Malaysia above 700 MW; US$2.3bn green financing 2026-07-29 and Malaysia's first renewable VPPA for a data center (ib vogt, 2026-07-01). · source ◐ secondary, confidence high
Recorded readiness — 2 of 6 applicable milestones have a dated public record
Gate to first power — target 2024-07-30 (announced) · path: Grid supply · each step must finish its lead time before the target
0 of 0 required steps have a public date. Red = recorded date past the rule-based deadline · grey "no public date" = required step without a record · green = on record in time · context steps never colour.

This site is energized; lights only show how its recorded steps compared with the lead times.
Lead-time assumptions
- Site secured 15 months before first power — Land under control and campus announced. Rarely binding; shown for context.
- Permits in hand 0 months before first power — Final air and siting permits. Operators often energize on standard or temporary authorisations and receive the major permit later; flagged only when the permit lands more than 6 months after first power or is missing for an on-site plant.
- Grid supply agreed 9 months before first power — Interconnection or large-load agreement approved. Observed median 7 months before first power; the physical works (substation, lines) run in parallel with construction.
- Substation and lines energized 2 months before first power — Utility delivery point live; final tests before the load is taken.
- New generation online 1 months before first power — Utility plant or on-site plant generating; needed just before energization when the grid cannot carry the load alone.
- Major equipment on site 6 months before first power — Turbines, transformers, switchgear delivered; installation and commissioning take the remaining months.
- Construction started 24 months before first power — Groundbreaking of the building that gives first power. Observed 4-26 months for recent AI campuses; Meta's redesigned campuses took 35-58.
- Building ready for IT 0 months before first power — First building ready for IT. 'Complete' or 'opened' is usually reported after first power; flagged only beyond 3 months.
- Full build-out complete -12 months before first power — All announced buildings operational. Comes after first power by design; context only.
- Water supply secured 12 months before first power — Water rights, municipal agreement or desalination contract in hand. Context only; one of the feasibility items.
- Financing closed 12 months before first power — Project financing, anchor lease or committed capital announced. Context only; not applicable when the owner is a hyperscaler building on its balance sheet.
