Summary
DayOne Data Centers, a Singapore-based operator, is building the Chonburi Tech Park hyperscale campus in the AMATA City area of Chonburi province, southeast of Bangkok. Groundbreaking was reported in March 2025 for a design of 180 MW of grid capacity in two phases, which trade press tied to a US$1 billion multi-year investment. In November 2025 DayOne added adjacent land that lifts the first site (CTP1) to 300 MW and signed an MoU with Amata for a second plot (CTP2) aimed at a 1 GW platform, plus a floating-solar supply deal. In April 2026 DayOne said more than 100 MW of IT capacity was expected to go live during 2026.
Source record as of 2026-04-26 · Details and sources
DayOne's F-1, filed October 5, 2026, reports its Thailand campuses at Chonburi Tech Park as of September 20, 2026. They had 120 MW of bookings: 73 MW of Capacity In Service (ready for service and fully fitted out) and 47 MW under construction. The campus is therefore partly in service; this does not establish completion of every phase or site. evidence

|---|---|---|---|---|---|
| Power capacity | 180 MW | Planned · Campus · Grid connection | 2025-03-19 | Grid capacity of the campus as designed at groundbreaking, to be built in two phases; later raised for CTP1 (see the 300 MW figure). | Intelligent CIO APAC |
| Power capacity | 300 MW | Planned · Phase · Unspecified · CTP1 with November 2025 land expansion | 2025-11-10 | Site power capacity of the first plot after adding adjacent land; the sources do not say whether this is IT or grid capacity. | DayOne Data Centers; Bernama; DayOne Data Centers |
| Power capacity | 1,000 MW | Planned · Campus · Unspecified | 2025-11-10 | Target for a combined 1 GW power platform across CTP1 and the future CTP2 plot; CTP2 was covered only by an MoU. | DayOne Data Centers; Bernama |
| Power capacity | more than 100 MW | Planned · Phase · It load · Capacity due to go live in 2026 | 2026-04-26 | IT capacity DayOne expected to bring online during 2026 as part of a multi-phase rollout. | DayOne Data Centers (via AAP / Cision) |
| Investment | 1,000,000,000 USD | Announced · Campus | 2025-03-19 | Intelligent CIO ties a US$1 billion investment, committed over the next few years, to this campus.

Power supply
| Type | Description | Sources |
|---|---|---|
| Grid | The campus was designed around 180 MW of grid capacity; solar power is delivered through the Provincial Electricity Authority grid. | Intelligent CIO APAC; DayOne Data Centers |
| Solar | Private power purchase agreement with AMBRE for a 22 kV floating-solar plant in the AMATA City estate, initially 42.5 MWp, expected to start commercial operation in 2027. | DayOne Data Centers; Bernama |
Amata Corporation signed the November 2025 MoU covering CTP2 and the land added to CTP1 and is called a strategic partner, but no formal ownership or development role is stated, so it is not listed as a party. The US$1 billion rests on one trade-press report (s1); DayOne's April 2026 release frames it as a Thailand-entry commitment. That release describes the campus as under development with capacity due in 2026; no source confirms capacity was live by October 2026. Only Intelligent CIO places the campus in AMATA City; DayOne's pages name Chonburi province. Province coordinates come from Wikipedia (s5), used only for the map point.
