Thailand Data Center Investment Boom in EEC Zone
Thailand's data center investment is surging, with project values jumping to 335 billion baht in early 2025, and the Eastern Economic Corridor is poised to overtake Bangkok's dominance within two years through better infrastructure and ince
Thailand's data center sector is accelerating sharply, with BOI-approved project values jumping from 98 billion baht in 2024 to 335 billion baht in the first nine months of 2025, according to Kasikornbank Research. This surge is expected to drive average data center capacity expansion of roughly 59% annually through 2026-2028.
Currently, Bangkok and its metropolitan areas remain Thailand's primary data center hub, accounting for about 52% of national capacity, while the EEC region holds approximately 41%. This reflects how existing investment clusters remain concentrated in Bangkok as the country's business center.
The EEC is rapidly becoming a new growth engine for data centers, leveraging abundant land, industrial parks, and benefits such as long-term land leases, environmental permits, and construction support. Data center projects under construction in the EEC with expected completion by 2028 total 149.9 MW—nearly double the 76.7 MW in Bangkok and its surroundings.
However, EEC's growth depends on adequate electricity and water supplies. Currently, the electrical grid in the EEC region has limited capacity for data center investment, though authorities are upgrading the network by 1,150 MW total—with 400 MW already operational and 750 MW under development.
Water availability presents constraints in Chachoengsao and Rayong, where industrial factories are heavily concentrated. However, Chachoengsao has 63% water reserves remaining, positioning it as more attractive for data center investment than other EEC areas.
