• Bangkok is Southeast Asia’s second-largest data centre market.
• Global operators shifting to large campuses in Bangkok and the EEC.

Bangkok has quickly become one of Southeast Asia’s largest data centre hubs, according to a report from DC Byte. With IT capacity now above 2.5GW, it sits just behind Johor in regional capacity ranking. Growth is powered by specific advantages: available land, steady power supply, and a location that connects East and West. The factors are drawing in major operators and global cloud companies.

Until recently, Thailand’s data centre market was made up of smaller, retail-style sites. Over the past two years, that has shifted toward full-scale campuses and large, multi-building projects. New development is also spreading outside central Bangkok into the Eastern Economic Corridor, especially in Chonburi, which is emerging as a strategic zone for hyperscale builds.

Global players and big investments

Amazon Web Services, Google, Microsoft, and Chinese providers including Huawei, Alibaba, and Tencent have committed to major projects in Thailand. Examples include Bytedance’s $8.8 billion investment, AWS’s $5 billion expansion, Google’s $1 billion site in Chonburi, and Microsoft’s first Thailand cloud region.

Operators like STT GDC, Equinix, DAMAC Digital, and Evolution Data Centres are also expanding. Between 2019 and 2024, Bangkok’s total IT capacity grew more than twenty-fold, with pipeline capacity rising at an average of about 40% each year.

At present, Bangkok has around 120MW of live capacity, with more expected before year-end as sites under construction come online. The next two years is expected to see another surge, with large projects from Google, DayOne, and Edgnex Data Centres by DAMAC among those set to launch.

Eastern Economic Corridor becomes Thailand’s data centre hub

The Eastern Economic Corridor (EEC) is fast becoming Thailand’s centre for large-scale deployments. Chonburi and Rayong are attractive for hyperscalers because of cheaper land, existing infrastructure, and easy access to ports and industrial zones.

Chonburi is now home to some of the country’s biggest upcoming builds. Projects like DayOne’s 120MW Tech Park and Bridge Data Centres’ planned 200MW campus will increase local capacity. Demand is so strong that both local and global operators are already locking in space before builds are complete.

One of the biggest announcements came in 2024, when Doma Infrastructure Group revealed plans for 1.5GW of green data centre campuses in the EEC. That accounted for most of the 1.7GW increase in early-stage capacity during the year, marking the shift from smaller facilities to large, multi-site campuses.

Cloud and AI power Thailand’s data centre demand

Cloud services remain the main source of growth, making up about 38% of Thailand’s total capacity in early 2025. AI is quickly catching up, rising from 20% of demand in 2024 to 28% just a year later. Growth is being fueled by AI training, large language models, and other data-heavy applications.

To meet the need, operators are working with partners like Siam AI Corporation, an NVIDIA cloud partner, to design facilities built for high-density AI workloads. The efforts could help Thailand develop into both a regional cloud hub and a centre for AI innovation.

Public and private efforts align

Government support is also shaping the market. Partnerships with NVIDIA aim to build sovereign AI capabilities, while major operators like True IDC, Edgnex Data Centres by DAMAC, and GSA Data Center Company are teaming up with Siam AI Corporation on AI-focused cloud services.

The mix of public and private investment is establishing the groundwork for next-generation infrastructure. With rising demand for AI and cloud services, Thailand is positioning itself to meet regional needs and strengthen its role in the wider Southeast Asian market.
