Malaysia's Johor state, which has approved 51 data centre projects as of November, stops approvals for new low-tier data centers citing high water consumption
JOHOR will stop approving applications for Tier 1 and Tier 2 data centres due to their massive water consumption, which can reach up to 50 million litres a day.
Context & Ripple Effects
Johor’s rapid data-center buildout had already brought concerns about power and water constraints, despite the jobs associated with the earlier wave of roughly 50 projects. The state had also become a destination for projects seeking cheaper land and energy, as covered in its data-center investment surge.
The halt narrows that expansion rather than reversing it: Johor has approved 51 projects, but is now using water intensity to distinguish which new facilities may proceed.
First-order effects
- Developers seeking new Tier 1 or Tier 2 facilities in Johor lose a permitting route, while the state protects water capacity from projects it characterizes as highly consumptive.
- The decision makes water use an immediate siting and design constraint for prospective data-center projects in Johor.
Second-order effects
- Operators and customers needing Malaysian capacity may redirect lower-tier projects to other locations or pursue facility designs and classifications that can satisfy Johor’s approval criteria.
- The restriction reinforces the broader Malaysian policy shift documented in efforts to rein in expansion amid utility shortages, raising execution risk for development pipelines dependent on local water availability.
Third-order effects
- If replicated across major data-center hubs, access to water and power will increasingly determine buildable capacity alongside land cost, turning infrastructure permitting into a more consequential competitive differentiator.
- The pattern points to a stronger social-license requirement for AI infrastructure: growth may continue, but developers will need to show that resource demands can coexist with local utility needs.
The trend: Data-center growth is moving from a land-and-capital race toward a resource-constrained buildout shaped by power, water, and local approval standards.
