Is Thailand Becoming Southeast Asia’s Data Centre Hub?
Bangkok is swiftly becoming a prominent hub for data centers in Southeast Asia, underpinned by robust energy infrastructure.
With its IT capacity now exceeding 2.5 GW, the city has ascended to the position of the second-largest market in the region after Johor. Its abundant land resources, reliable energy supply and strategic location as a conduit between East and West, have magnetised multinational operators and hyperscalers seeking to capitalise on these assets.
This shift marks a notable evolution for Thailand’s data center industry. Where previously, smaller, retail-oriented facilities prevailed, large-scale campuses and multi-building projects are now emerging, especially beyond the confines of Bangkok’s urban core and into areas like the Eastern Economic Corridor (EEC).
“Given the scale of development expected this year, Chonburi’s capacity is tightening rapidly," says Nicole Seah, Research Analyst at DC Byte.
"Securing large-scale power allocations for 2026 may prove increasingly challenging, making early engagement essential.”
Momentum from global hyperscalers
Bangkok's emergence as a hyperscale-ready market is underscored by investments from global cloud leaders. AWS has outlined a US$5bn commitment, Google is pledging a US$1bn facility in Chonburi, and Microsoft has inaugurated its first cloud region in Thailand. Meanwhile, Huawei, Alibaba and Tencent, alongside Bytedance’s US$8.8bn investment, are solidifying their presence.
The influx of these players has catalyzed actions from operators like STT GDC, Equinix, DAMAC Digital, and Evolution Data Centres, driving a rapid expansion from 2019 to 2024, during which Bangkok's IT capacity multiplied over twentyfold, with pipeline capacity recording a strong annual growth rate.
Eastern economic corridor's role
The EEC stands as Thailand's central area for large-scale data centre development, with Chonburi and Rayong at the forefront. These regions benefit from ample land, competitive costs, and robust infrastructural connectivity, making them ideal for high-capacity, low-latency workloads.
Chonburi has quickly emerged as the hub of Thailand’s impending projects, with ventures like DayOne’s 120 MW Chonburi Tech Park and Bridge Data Centres’ planned 200 MW campus expected to heavily augment the nation’s active capacity in coming years. This development surge has prompted both local and international operators to secure land and energy allocations well ahead of burgeoning demand.
Energy demands from cloud and AI
Cloud services form the foundation of Thailand's advancing data capacity, accounting for roughly 38% by early 2025. Though hyperscaler deployments play a significant role in the market's transformation, demand from AI-related tasks continues to climb.
AI represented 28% of total capacity as of early 2025, up from 20% the previous year, driven by intricate training tasks, large language models, and data-intensive applications needing high-density infrastructure. Partnerships with local entities like Siam AI Corporation, a NVIDIA cloud partner, are actively designing AI-specific infrastructure to anticipate this future demand.
Thailand's digital ascent
With Bangkok's rapidly expanding capacity and the EEC’s momentum, Thailand is positioning itself as a key player in regional cloud infrastructure and an emerging nucleus for AI innovation. As major international and domestic firms deepen their investments, the need for early resource procurement remains high.
Bangkok, with its growing IT capacities and strategic geographic advantage, stands poised to contribute pivotal advancements to Southeast Asia’s evolving digital landscape.
