Singapore-headquartered DayOne Data Centers recently signed a Memorandum of Understanding (MoU) with Amata Corporation for the future development of Chonburi Tech Park Plot 2 (CTP2) and the expansion of its existing CTP1 campus, which together, will create Thailand’s first 1GW power platform, complemented by a renewable-energy agreement with Amata B.Grimm Renewable Energy Company Limited (AMBRE) to supply clean power to its facilities.
The CTP1 expansion adds 41.3 rai (16.3 acres) of adjacent land, bringing the site’s power capacity to 300MW. Together, CTP1 and CTP2 establish the foundation for a unified 1GW power platform, anchored by CTP1 which is under construction and enabled by the future development of CTP2. This will create Thailand’s first gigawatt-scale power platform and one of Southeast Asia’s largest single-site digital-infrastructure campuses.
DayOne entered Thailand in 2024 driven by surging cloud and AI-driven demand. Chonburi was chosen for its strategic position within the Eastern Economic Corridor (EEC), its resilient industrial utilities and connectivity, and the supportive investment environment aided by agencies such as the Thailand Board of Investment (BOI) and Amata’s long–term development framework, says DayOne’s statement.
At the same event, DayOne and Amata B.Grimm Renewable Energy Company Limited (AMBRE) have signed a Private User Power Purchase Agreement (PPA) to supply renewable solar energy to DayOne’s Chonburi Tech Park data center campus. AMBRE will supply renewable electricity generated by a 22 kV floating – solar facility with an initial capacity of 42.5 MWp within the Amata City Chonburi estate. The plant is expected to begin commercial operation in 2027, with integration through the Provincial Electricity Authority (PEA) grid under a tripartite agreement among DayOne, AMBRE, and PEA. The renewable power will enable DayOne to progressively decarbonize operations across the campus.
“Our strong commitment in Thailand reflects DayOne’s belief in this market as a core pillar of our regional growth strategy,” said Jamie Khoo, CEO of DayOne Data Centers. “With our partners across government and industry, we are building the scale, infrastructure and sustainable energy foundation necessary to support next-generation digital services, cloud and AI ecosystems. The continued expansion of our Chonburi campus is establishing a 1GW platform—Thailand’s first and one of the most significant single-site developments in Southeast Asia.”
Vikrom Kromadit, Chairman of Amata Corporation, added: “The expansion of DayOne’s hyperscale data center at our Chonburi campus marks a significant milestone not only for DayOne, but also for Amata and Thailand. Through the collaborative efforts of all parties, we are able to provide global investors with the infrastructure and sustainable utilities they need to succeed.”
The signing ceremonies were witnessed by senior representatives from the Thailand Board of Investment (BOI), the Eastern Economic Corridor (EEC), the Industrial Estate Authority of Thailand (IEAT), the Provincial Electricity Authority (PEA), Amata Corporation, and DayOne Data Centers.
