South-east Asia’s rapid transformation into a global artificial intelligence infrastructure hub has hit a regulatory and resource wall, as governments across the region halt dozens of multi-billion-dollar construction projects to combat severe power and water shortages.
Assessing Regional Constraints
- Regulatory Stalls: Thailand paused construction on 49 datacentre sites and delayed 117 approval decisions in September 2026, while West Java’s governor halted construction on a major facility due to missing permits and incomplete environmental assessments.
- Resource Strain: Energy consultancy Wood Mackenzie reports that datacentres in Malaysia’s Johor state currently devour 24% of total power consumption, a figure projected to climb to 40% by 2035.
- Policy Overhauls: Governments are instituting stringent new frameworks, including higher electricity tariffs for heavy users and outright bans on inefficient Tier 1 and Tier 2 facilities that drain local water supplies.
Thailand and Indonesia Freeze Major Infrastructure Pipelines
In early 2026, Thailand’s board of investment approved major digital infrastructure initiatives from TikTok, UAE-based Skyline, and Singapore’s Bridge Data Centres, representing a combined $27 billion investment pipeline, according to reporting by The Guardian. By September 2026, however, regulatory momentum reversed sharply. Authorities halted construction on 49 active builds and suspended 117 pending applications. The suspensions stem from growing oversight concerns over inadequate environmental monitoring and ambiguous regulatory frameworks.
Neighboring Indonesia faces parallel bottlenecks. The governor of West Java halted construction on a regional datacentre project, citing missing permits and deficient environmental assessment files. These regulatory interventions reflect a broader regional reassessment as local authorities grapple with the sheer scale of the infrastructure boom. Cushman and Wakefield data shows that south-east Asia commands roughly 50% of the entire Asia-Pacific under-construction datacentre capacity, led primarily by developments in Malaysia and Thailand.
Johor Emerges as a Hyperscale Epicenter Amid Grid Pressures
Through the 2010s, Singapore was south-east Asia’s leading datacentre hub, and the city-state implemented a moratorium on new datacentres from 2019 to 2022 because they were intensive users of water and electricity, as described in a press release from the Ministry of Energy, Trade and Industry. While Singapore has since resumed selective approvals—adding just 95 megawatts of operational capacity between 2023 and 2026—capital has flooded across the border into Malaysia’s southern state of Johor.
Johor’s operational capacity surged more than tenfold from 94MW in 2023 to 1,110MW in 2026, with an additional 3,088MW under construction or planned. State government head Onn Hafiz Ghazi noted that Johor has attracted $40 billion in total investments. Major multinational deployments include Microsoft (NASDAQ: MSFT), which launched a $2.2 billion cloud and AI infrastructure expansion across Kuala Lumpur and Johor in 2024, alongside Australian operator AirTrunk’s $3 billion commitment to double its local footprint.
| Hub / Region | Operational Capacity (2026) | Pipeline / Under Construction | Key Corporate Commitments |
|---|---|---|---|
| Johor, Malaysia | 1,110 MW | 3,088 MW | Microsoft ($2.2bn), AirTrunk ($3bn) |
| Greater Jakarta & Batam, Indonesia | Regional Scale | 1,699 MW | Microsoft ($1.7bn), Princeton Digital Group, Digital Edge |
| Bangkok Corridor, Thailand | Growth Phase | 2,084 MW | TikTok, Skyline, Bridge Data Centres ($27bn total approvals) |
| Singapore | Restricted Growth (95MW added 2023–2026) | Highly Selective | Alibaba, Meta (legacy hubs under strict sustainability caps) |
Rapid Facility Expansion Strains Municipal Utilities
The hyper-expansion of energy-intensive facilities is straining municipal utilities. Wood Mackenzie analyst Alvin Tan warned that rapid growth risks severe localized grid bottlenecks, necessitating expensive transmission network upgrades and new generation capacity. Thailand’s energy minister, Akanat Promphan, pointed out that these facilities rely heavily on expensive imported gas, prompting proposals for a specialized electricity tariff category for industrial tech operators.
Water scarcity has compounded these operational headwinds. Johor facilities require massive amounts of water daily in a drought-prone climate, while Indonesian operators utilize water-cooling systems ill-suited for hot lowland environments. In Thailand’s Eastern Economic Corridor, local advocacy groups like EEC Watch have raised alarms over industrial extraction from the shallow Khlong Luang Reservoir. Public friction surfaced in February when Johor residents picketed a construction site belonging to China’s ZData Technologies over dust pollution and water security fears.
Governments Enforce Strict Resource Efficiency Requirements
In response to mounting ecological and infrastructure pressures, regional governments are embedding strict resource efficiency requirements into statutory approval processes. Malaysia established a dedicated datacentre taskforce, and Johor authorities announced they will no longer approve low-efficiency Tier 1 and Tier 2 facilities that consume up to 50 million liters of water daily.
Operators are attempting to mitigate resource friction through engineering adjustments. Bridge Data Centres constructed a dedicated water reclamation plant in Johor, while AirTrunk partnered with Johor Special Water to recycle wastewater. Nevertheless, sustainability metrics remain uneven.
