DayOne Chonburi Tech Park Program

PRJ-0406 · Program · Amata City Chonburi, Chonburi, Thailand

Record last updated Oct 28, 2026

Scope and capacity

DayOne's October 5, 2026 SEC filing reports that its Thailand market had 73 MW of capacity in service and 47 MW under construction as of September 20. The filing defines in-service capacity as ready-for-service, fitted-out IT capacity, not measured power draw. These are Thailand-market totals, without an explicit allocation between CTP1 and CTP2, and are separate from the 300 MW power envelope and longer-term 1 GW ambition. DayOne is building a two-site Chonburi platform anchored by CTP1 and prospective CTP2, with a long-run 1 GW power ambition. DayOne Chonburi Tech Park Program is located in Amata City Chonburi, Chonburi, TH and is a program with development and market-level service progress reported.
