Southeast Asia operates about 3% of the world’s live data-centre capacity but accounts for about 10% of the capacity under construction.
Geopolitics and generous investment incentives have drawn data-centre investment to Southeast Asia faster than power grids and water supplies can expand to serve the new data centres. Malaysia and Singapore operate most of the live capacity, and US investors control ten of the 26 operators traced.
Geopolitics and generous investment incentives have drawn data-centre investment to Southeast Asia faster than power grids and water supplies can expand to serve the new data centres.
This Assessment examines the six ASEAN markets that host data centres or plan new ones: Singapore, Malaysia, Thailand, Indonesia, Vietnam and the Philippines. Brunei, Cambodia, Laos, Myanmar and Timor-Leste host little or no data-centre activity. Johor, in Malaysia, serves as the case study, since the gains and costs of construction are most visible there. MERIDIAN makes three dated calls for the period to 31 December 2027 and scores each call in public on 1 April 2027, 1 October 2027 and 31 December 2027.
Southeast Asia operates about 3% of the world’s live data-centre capacity but accounts for about 10% of the capacity under construction.
Malaysia and Singapore operate most of Southeast Asia’s live capacity, and US investors control more operators than investors from any other country.
Drivers: US–China rivalry and tax incentives bring cloud investment to Southeast Asia, but operators choose locations according to grid supply and data rules.
In Johor, landowners, the Johor state government and Tenaga Nasional Berhad (TNB), Malaysia’s power utility, capture the gains from data-centre construction, while households would bear the cost of a water shortage.
Constraints: power grids and water supplies cannot keep pace with the data-centre capacity committed across Southeast Asia.
Obstacles: a forecast drought, government limits on approvals and local protest could halt committed projects, and Indonesia and the Philippines are likely to restrict approvals next.
Three of MERIDIAN’s four directional lenses find that the build-out holds within physical and institutional limits, and the capital lens finds that announced capital overstates the capital in deployment.
Each government regulates data centres through a different main policy, and the stability of governing political coalitions matters more to investors than tax incentives or election dates.
MERIDIAN expects capital to keep flowing, grid connections to hold delivery behind the pipeline and more ASEAN governments to attach conditions to approvals, and each scenario turns on one of the three calls.
Recommendations: resource and capacity planning are critical criteria before data-centre approval, and investors should watch grid connection dates rather than signed supply agreements.
