AirTrunk Commences Construction on TOK1 Phase 3 Data Centre in Tokyo

Hyperscale data centre specialist AirTrunk has commenced the construction of the third phase of AirTrunk TOK1, a massive data centre project in East Tokyo. With a capacity of over 300MW, the new facility will be purpose-built to cater to the needs of a major technology client. AirTrunk has announced that the new phase started just a few months after constructing a 50+MW phase at TOK2 in West Tokyo.

AirTrunk HKG2

Simultaneously, in the last week of June, AirTrunk unveiled plans for its second data centre in Hong Kong, named AirTrunk HKG2 (HKG2). Considering the increasing demand for critical digital infrastructure in the region, HKG2 will be scalable to over 15MW. Strategically situated in a new cloud availability zone in East New Territories, the initial capacity is expected to be delivered to the anchor tenant by mid-2024.

According to the statement, the introduction of HKG2 complements AirTrunk's existing HKG1 facility, which began operations in late 2020 in the West New Territories. These two data centres offer over 35MW of capacity in Hong Kong, providing location diversity for AirTrunk's large technology clients.

AirTrunk said adding HKG2 further strengthens AirTrunk's APJ platform, which already comprises data centres in Australia, Japan, Singapore, and Malaysia. Across the region, the platform will boast a total capacity of nearly 1.38GW.

HKG2 will be a retrofit of an existing building designed to meet the security requirements of global technology customers, including certifications such as PCI DSS, ISO27001, and SOC2 Type 2.

Sustainability Measures

AirTrunk has made a commitment to environmental sustainability by setting its sights on achieving an industry-leading power usage effectiveness of 1.25 for HKG2. Additionally, as part of its broader emissions commitment, the company plans to achieve Net Zero emissions by 2030, alongside renewable sourcing options.

In November 2022, AirTrunk partnered with CLP Power to launch a first-of-its-kind renewable energy solution in Hong Kong. The initiative involved matching Microsoft's data centre electricity consumption with local renewable energy certificates (RECs) at AirTrunk's HKG1 data centre.
