Singapore - headquartered DayOne Data Centers today announced a major step toward creating Thailand’s first 1GW power platform, marked by 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. DayOne also signed a renewable - energy agreement with Amata B.Grimm Renewable Energy Company Limited (AMBRE) to supply clean power to its facilities. CTP2 marks the next major growth zone for DayOne in Chonburi. Complementing this, the CTP1 expansion adds 41.3 rai (approximately 16.3 acres) of adjacent land, bringing the site’s power capacity to 300MW. Together, CTP1 and CTP2 establish the foundation fo r a unified 1GW power platform, anchored by CTP1 already under construction and enabled by the future development of CTP2, creating Thailand’s first gigawatt -scale power platform and one of Southeast Asia’s largest single -site digital -infrastructure campus es. These developments strengthen Thailand’s digital - economy ecosystem through enhanced supply chains, skilled employment and sustained technology investment.

DayOne entered Thailand in 2024 to address surging cloud and AI - driven computing demand across the region. Chonburi was chosen for its strategic position within the Eastern Economic Corridor, its resilient industrial utilities and connectivity, the support ive investment environment shaped by agencies such as the Thailand Board of Investment (BOI) and Amata’s long -term development framework. The expansion builds on DayOne’s long -term commitment to deliver efficient, sustainable digital infrastructure in supp ort of Thailand’s national vision to become a regional digital -services hub.

Complementing the land expansion, DayOne and Amata B.Grimm Renewable Energy Company Limited (AMBRE) have entered into a Private User Power Purchase Agreement (PPA) to supply renewable solar energy to DayOne’s Chonburi Tech Park data center campus. Under the arrangement, AMBRE will supply renewable electricity gen erated 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 unde r a tripartite structure among DayOne, AMBRE, and PEA. The renewable power will enable DayOne to progressively decarbonize operations across the campus.
