APAC data center company DayOne plans to expand its data center in Thailand.

The company plans to eventually scale the Chonburi Tech Park (CTP) campus to 1GW, having broken ground on the first facility this March with 180MW of grid capacity.

The CTP1 data center, which is still under construction, will now grow to 300MW with an expansion on 16.3 acres of adjacent land.

DayOne also announced plans for CTP2, with the company signing a Memorandum of Understanding (MoU) with industrial estate provider Amata Corporation.

“The expansion of DayOne’s hyperscale data center at our Chonburi campus marks a significant milestone for both Amata and Thailand," Vikrom Kromadit, chairman of Amata, said.

"Through the collaborative efforts of all parties, we are creating the infrastructure and sustainable utilities global investors need to succeed.”

Alongside the MoU with the real estate division, DayOne entered into a Power Purchase Agreement (PPA) with Amata B.Grimm Renewable Energy Company Limited (Ambre).

Ambre will supply renewable electricity generated by a 22kV floating-solar facility with an initial capacity of 42.5MWp within the Amata City Chonburi estate, starting in 2027.

“Our strong commitment in Thailand reflects DayOne’s belief in this market as a core pillar of our regional growth strategy," DayOne CEO Jamie Khoo said.

"The continued growth of our Chonburi campus puts us on a clear path toward a 1GW platform that will serve the region’s long-term digital future.”

DayOne is the former international business unit of Chinese data center firm GDS, and rebranded as an independent company earlier this year.

The company’s portfolio currently comprises more than 500MW of data center capacity in service and under construction, and more than 500MW held for future development across sites in Hong Kong, Singapore, Malaysia (Johor), Indonesia (Batam), and Japan (Tokyo). The company recently broke ground on a site in Singapore.

In August, it made its first foray into markets beyond Asia, announcing a campus in Lahti, Finland, around 100km northeast of Helsinki.
