Malaysia leads Southeast Asia's upcoming data center expansion with over 6 GW in the pipeline, followed by Thailand at approximately 3.5 GW, positioning both countries at the forefront of the region's hyperscale growth cycle. Southeast Asia's upcoming data center capacity is nearly four times the current operational capacity. Malaysia dominates the existing market with a power capacity of more than 1 GW, driven by major players like Vantage Data Centers, DayOne (GDS Services), Bridge Data Centers, and Princeton Digital Group.

The surge reflects Southeast Asia's transformation into a primary destination for AI infrastructure investment. Southeast Asia hosts around 303 existing data centers, with countries like Singapore, Malaysia and Indonesia having a strong presence in the region. Malaysia is expected to see the steepest rise in power consumption, with an expected sevenfold increase from just 8.5 TWh in 2024 to 68 TWh in 2030. Such growth will also push the share of data centre power demand to 30% of the country's total demand in 2030.

This pipeline positions Malaysia and Thailand as critical components of the region's digital infrastructure backbone. Johor anchors Malaysia's next phase of data center growth, with an estimated pipeline exceeding 3.5 GW and strong momentum from key operators such as ST Telemedia Global Data Centres, Racks Central, EdgeConneX and domestic data center operators. Thailand's total IT capacity grew by more than 2,000% between 2019 and 2024, and capacity is expected to triple from 350MW in 2024 to roughly 1GW by 2027. The scale represents a fundamental shift in global data center investment patterns toward Southeast Asia's emerging markets.

After imposing a moratorium on new data-center developments between 2019 and 2022 to address energy and land constraints, Singapore resumed approvals under stricter efficiency and sustainability requirements. Land availability, relatively lower power costs, and proximity to Singapore's connectivity infrastructure have made Johor a focal point for hyperscale investment and large campus-style developments.

YTL Power's Nvidia‑backed AI campus, AirTrunk's hyperscale facility, and Microsoft's land acquisitions and planned cloud region in Johor all show how large, power‑intensive infrastructure is shifting just across the Singapore border.

New research shows Malaysia's 6GW development pipeline leads Thailand's 3.5GW, positioning both as hyperscale hotspots

6GW pipeline makes Malaysia Southeast Asia's data centre leader

Research reveals Malaysia leads with over 6GW planned capacity, Thailand second with 3.5GW

Malaysia leads Southeast Asia's upcoming data center expansion with over 6 GW in the pipeline, followed by Thailand at approximately 3.5 GW, positioning both countries at the forefront of the region's hyperscale growth cycle. Southeast Asia's upcoming data center capacity is nearly four times the current operational capacity.

Emerging markets like the Philippines and Vietnam are entering rapid expansion phases, diversifying the overall regional footprint. Studies forecast a 19.4% annual growth of data centre capacity in the region from 2022 to 2026 and 19% from 2024 to 2028. This steady growth of the data centre industry in Southeast Asia will naturally lead to an increase in power demand from the sector.
