NTT Breaks Ground on Bangkok 4 Data Center Campus in Chonburi, Thailand

By: IDCNOVARegion: Southeast Asia
Japanese telecommunications giant NTT has officially broken ground on its new data center campus in Chonburi, Thailand, marking a significant expansion of its digital infrastructure footprint in Southeast Asia. The facility, known as Bangkok 4, is expected to be energized in the second quarter of 2027, according to a statement from NTT Global Data Centers on LinkedIn.

This development comes as part of NTT’s broader strategy to scale its global data center capacity. In March 2026, CEO Doug Adams revealed that the company was working to double its total capacity to 4 gigawatts within as little as two years, underscoring the surging demand for cloud and AI-driven computing power across the region.

NTT Global Data Centers also announced that Fuji Electric will be responsible for building the campus’s electrical substation, a critical component for ensuring reliable power delivery to the facility. The substation will support the campus’s operations under a previously signed 100-megawatt power purchase agreement with Thai utility B.Grimm Power, which was finalized in January 2026.

Bangkok 4 will become NTT’s fourth data center in Thailand, with all existing facilities located within the Bangkok metropolitan area. The new campus in Chonburi, a key industrial province east of Bangkok, is poised to strengthen the country’s position as a regional hub for data center investment. Industry analysts note that the project reflects a broader trend of hyperscale and colocation providers expanding into secondary markets in Asia to meet growing latency and data sovereignty requirements.

The groundbreaking also highlights the increasing importance of energy procurement and infrastructure partnerships in data center development. By collaborating with Fuji Electric and B.Grimm Power, NTT is ensuring that the campus will have access to stable and scalable power, a critical factor for operators racing to bring new capacity online amid tightening grid constraints across the region.
