Summary

  • STTGDC secured a JPY 93bn green-loan facility to finance fit-out and subsequent operation of TYO1 and TYO2 in Inzai City; the announced campus capacity is 70.8MW of IT load.
  • Eligibility includes green-building certification and a design PUE of 1.3 or below. TYO1 has achieved LEED Gold and carries a design PUE below 1.25; TYO2 is still in development and targets LEED Gold.
  • The release names coordinators and buildings but gives no drawdown, tenor, price, building-by-building allocation, measured PUE or certification deadline.

The green loan has a hard number and a soft edge. STTGDC says it secured JPY 93bn to fit out and operate TYO1 and TYO2, a two-building campus in Inzai City, Chiba Prefecture. The campus is expected to deliver 70.8MW of combined IT capacity. The loan’s environmental eligibility criteria include a green-building certification and design Power Usage Effectiveness (PUE) of 1.3 or lower.

The verb matters. This is a design threshold, not an operating result. PUE compares total facility energy with the energy used by IT equipment; a lower ratio means less overhead around the computing load. The release gives no measured operating ratio for either building. A line on a design brief and a year of meter readings are different evidence objects, even when they share the same decimal place.

TYO1 gives the green criteria a real foothold. It is STTGDC’s first operational data centre in Japan, has achieved LEED Gold, and is designed for annualised PUE below 1.25. Its closed-loop cooling is designed to avoid ongoing water consumption during normal operations. The older August certification announcement describes the LEED award as an independently assessed result; the PUE remains a design figure.

TYO2 is the unfinished half of the campus. STTGDC says it is being developed for high-density AI and accelerated-computing workloads, with provision for future liquid cooling. It is targeting LEED Gold and TIA-942-C Design Certification. The 27 October release does not give a commissioning date, a PUE measurement schedule or a deadline for either certification. The campus total therefore joins one operational facility to one development project.

That distinction keeps the finance arithmetic honest. Dividing ¥93bn by 70.8MW produces a number, not a disclosed construction cost per megawatt. The facility funds fit-out and subsequent operation, and STTGDC does not allocate proceeds between TYO1 and TYO2 or between those uses. The same release reports a secured facility; it does not say the whole amount has been drawn.

The lending group is unusually legible. Standard Chartered acted as Lead Coordinator, with Mizuho Bank, OCBC, Société Générale and UOB supporting the financing. Standard Chartered and Société Générale also acted as Green Loan Coordinators. The public release still leaves the items that would price the capital: tenor, interest rate, repayment schedule, drawdown and the conditions attached to each building.

So the announcement establishes a financing commitment and a design-screening rule. It does not yet establish what the loan costs, how much is outstanding, or how the green criteria will be checked after construction. Those details belong in the next public update, alongside measured facility performance and the certification state for TYO2.
