The 122 GW Map:
Where ASEAN Stands in the Global Data Center Race

The U.S. now hosts 44% of the world's data center capacity. Southeast Asia hosts barely 3%. But the growth math has flipped — and faster than most regional planners realize. Operators still treating Singapore as their only Southeast Asian compute address are paying for it.

The 122 GW world

The world's installed data center capacity reached 122.2 gigawatts by Q1 2025, according to Synergy Research Group. Twenty years ago, it was 21.4 GW. A fivefold increase, with the last seven years accounting for almost all of it.

This year, JLL forecasts the sector will add another 97 GW by 2030 — effectively doubling global capacity in five years. McKinsey puts the cumulative capital expenditure required at $6.7 trillion by 2030, with $5.2 trillion of that earmarked specifically for AI infrastructure. To put that in context: the four largest hyperscalers — Microsoft, Google, Amazon, Meta — plan to spend more than $400 billion on data center capex in 2026 alone. That is more than the entire annual federal budget of Indonesia.

But the geography of this spending is still grotesquely unbalanced. The United States hosts 53.7 GW operational — 44% of global capacity. China holds roughly 26 GW, the second pillar of the global stack. Together they account for 70% of the world. The European Union, 11.9 GW combined.

Northern Virginia alone — a single county cluster outside Washington D.C. — operates 4,040 MW, having added more than 1 GW during 2025. That single market is larger than the entire installed base of Japan.

Where APAC actually stands

APAC, despite being the demographic and economic gravity center of the next two decades, hosts only 13.8 GW of operational capacity (Cushman & Wakefield, H2 2025). Barely 11% of the global total. Within APAC, the concentration is tighter still. Five markets account for roughly 80% of operational capacity: Chinese mainland (4.5 GW), Japan (1.5 GW, Tokyo dominant at 1,489 MW), Australia (1.3 GW, Sydney), India (1.3 GW), and Singapore (1.0 GW).

Tokyo and Singapore are mature, near-saturation markets. Vacancy rates in Singapore sit at 2% or below; new tenants pay $310–$470 per kW per month — among the most expensive rates in the world (CBRE).

Singapore's growth ceiling is structural, not strategic. The 2019 moratorium on new data centers — formally lifted in 2022 but replaced with the Data Centre Call for Application (DC-CFA) regime — allocates capacity by competitive tender, with a 50% renewable energy mandate and PUE ceiling of 1.25. The 2026 DC-CFA2 round opened up just 200 MW. The market remains the most disciplined in Asia, and that discipline is precisely what pushed billions in deferred hyperscale demand across the Causeway to Johor.

ASEAN's promotion

Here is the line that should reframe how operators think about Southeast Asia. In the Cushman & Wakefield 2026 Global Data Center Market Outlook, Johor was elevated to the world's top 10 primary markets — alongside Northern Virginia, Dallas, Beijing, London, and the other heavyweights. The only other APAC entry in the top 10 is Sydney. Johor recorded a 124% year-on-year growth rate, one of the fastest of any market on Earth.

And it is not alone.

Malaysia has a 5.7 GW project pipeline in Johor and major hyperscale anchors in Selangor. Tenaga Nasional Berhad, the national utility, signed electricity supply agreements covering 6.4 GW across 43 data center projects by Q1 2025 — a number that climbed to roughly 7.1 GW by September. The supply lead time for high-voltage hookup under TNB's Green Lane Pathway is 12 months, compared to a global average of 4.5 years and an APAC average of 2 years 8 months. That speed differential is the single largest reason Johor is now competing with Northern Virginia for hyperscale anchor tenants.

Thailand is the next inflection point. Google committed $1 billion in September 2024 to build a data center in Chonburi and a cloud region in Bangkok, launching January 2026. AWS pledged $5 billion by 2037. Microsoft is building a separate Thailand DC region. ByteDance is in. Cushman's 2026 report places Bangkok at the top of APAC for capacity under construction.

Indonesia is the demand-side play. Microsoft announced a $1.7 billion four-year commitment in April 2024 — its largest ever investment in the country — covering infrastructure, AI skilling for 840,000 people, and developer ecosystem support. Jakarta remains the metro center, but Batam has emerged as a secondary hub absorbing Singapore overflow with a different cost structure than Johor. CBRE noted in Q1 2025 that Batam is now capturing "sizeable multi-MW transactions."

Vietnam is earlier-stage. Google is reportedly planning a hyperscale data center in Ho Chi Minh City, slated for 2027 operations — which would mark the first major U.S. tech infrastructure footprint in the country. The broader Vietnamese DC market remains constrained by data sovereignty regulations and slower grid expansion.

The Philippines, Cambodia, and Laos sit in the tens-to-low-hundreds of MW range. Laos's role in the regional architecture is different: under the Lao PDR–Thailand–Malaysia–Singapore Power Integration Project, operational since June 2022, Laotian hydropower is wheeled through three national grids to power Singapore's data centers. The country is, in effect, exporting electrons to host other countries' AI.

"The marginal megawatt — the one that decides whether a 2028 product can get built — is increasingly being installed in Johor, in Chonburi, in Subang."

What this reshapes

Three things, for anyone with operational exposure to Southeast Asia.

The "Singapore model" no longer scales. For two decades, the Singapore-as-regional-hub assumption shaped where multinationals located back-office, data, and cloud workloads. That model is now bound by hard physical limits the city-state has chosen not to relax. The new pattern is "twinning" — anchor in Singapore, execute in Johor or Batam — formalized in the Johor–Singapore Special Economic Zone signed in January 2025. Companies still treating Singapore as their only Southeast Asian compute address are paying for it.

The supply chain for compute is now an infrastructure-political question. AWS in Bangkok, Google in Chonburi and Ho Chi Minh, Microsoft in Jakarta — these are not retail expansions. They are sovereign-scale commitments that will shape which cities have low-latency cloud access, which regions become regional AI training hubs, and where multinational tenants are willing to colocate their own workloads in the next five years. If you are evaluating a 2027 or 2028 ASEAN expansion, the data center map is no longer a footnote. It is a site selection input.

Southeast Asian utility, water, and land regulators have become customer-facing. TNB in Malaysia sells "12-month grid connection" as a product feature. Johor state government rations water by data center tier. Indonesia's Ministry of Investment is the gating authority on Microsoft's $1.7 billion footprint. The institutions that used to be invisible to corporate site selection have become some of the most consequential negotiating counterparties in the region. The companies that learn to speak that language earliest will move fastest.

The number that matters

122 GW today. 200 GW by 2030. The U.S. will absorb most of it. China most of the rest. But the marginal megawatt — the one that decides whether a Japanese parts supplier or a Thai EMS contractor or an Indonesian fintech can build the products they want to build in 2028 — is increasingly being installed in Johor, in Chonburi, in Subang.

That is the map. It is not the one in most planning documents written before 2024. It is the one operators will work from for the next decade.
