NTT Global Data Centers has broken ground on a new electrical substation at its Chonburi campus in Thailand, in partnership with Fuji Electric Thailand.

The project marks Fuji Electric’s first data centre substation project in Thailand and its first collaboration with NTT Global Data Centers in the country.

NTT said in a LinkedIn post that the project will expand the campus’s power infrastructure to support additional data centre capacity for AI, cloud and hyperscale workloads.

B.Grimm and Amata B.Grimm Power were also named as project partners, although NTT did not disclose their specific roles or the equipment covered by Fuji Electric’s contract.

A substation receives electricity from the grid, adjusts it to the voltage required by the site and distributes it across the data centre campus.

The project follows a 100MW power purchase agreement signed by NTT Global Data Centers and Amata B.Grimm Power in January for the planned Bangkok 4 facility at Amata City Chonburi Industrial Estate.

Commercial operations under the agreement are scheduled to begin in June 2027. Amata B.Grimm Power already supplies electricity to NTT’s second and third data centres in Thailand.

B.Grimm Power has also partnered with other data centre operators in the country. In May, it secured a US$880 million green loan with Digital Edge to finance their 100MW BKK campus in Chonburi.

The financing, described by the companies as Thailand’s largest data centre loan, forms part of a US$1 billion joint-venture investment programme.

NTT Global Data Centers is the data centre business of NTT DATA, providing colocation and related infrastructure services across its international portfolio.

It operates multiple facilities in Thailand and is expanding its Chonburi campus with additional hyperscale capacity.
