Data-Centre Tracker

• Johor (Iskandar Puteri / Kulai). The epicentre — a strategic spillover from Singapore’s 2019–2022 moratorium. Live supply grew at roughly 145% a year from 2019–2024; the pipeline approaches 4 GW, with ~700 MW under construction by late 2025. Malaysia’s first Nvidia-powered AI data centre went live in Johor in October 2025.
• Klang Valley (Selangor / Cyberjaya). The established hub — home to Google’s first Malaysian data centre at Elmina and much of the early colocation capacity.
• Negeri Sembilan & Port Dickson. Emerging sites — Google purchased 389 acres in Negeri Sembilan and is developing a Port Dickson facility with Gamuda.

Data centres are, fundamentally, a power business. Malaysia’s appeal rested on cheap, reliable electricity and fast grid connection — Tenaga Nasional’s “Green Lane Pathway” cut connection timelines from up to 48 months to about 12. But success brought pressure:

• A July 2025 tariff reclassification moved large data centres into an ultra-high-voltage band, raising power costs an estimated 10–15% — for a 100 MW campus, on the order of RM63 million more per year.
• Operators are turning to renewable PPAs and liquid cooling to manage costs and meet sustainability conditions tied to incentives.
• Water is the quieter constraint — Selangor water-stress limits restrict evaporative cooling, pushing designs toward less water-intensive methods.

Across ASEAN, data centres are projected to grow from a small share of power demand toward a far larger one by 2030 — making energy, not capital, the real limiting factor on how far the boom can run.

The boom was deliberately engineered. The Digital Ecosystem Acceleration (DESAC) scheme, announced in 2022, offers tiered investment tax allowances and special tax rates to data-centre and cloud operators that meet local-hiring, wage and green-technology conditions. Of the 143 approved projects, 25 carried Malaysia Digital status under DESAC. Combined with the TNB Green Lane and renewable-supply schemes, it is one of the most aggressive data-centre incentive regimes in the region — and the reason capital chose Malaysia over its neighbours.
