Strategic Financing for Sustainable Infrastructure
DayOne, a Singapore-headquartered digital infrastructure platform, has secured a S$530 million green loan to finance the development of its first data centre in Singapore. The four-year financing facility is provided by a consortium of major banks—DBS, OCBC, and UOB—who are serving as Joint Mandated Lead Arrangers, Bookrunners, and Green Loan Coordinators.
The project, located in the Western region of Singapore, represents a significant shift in how digital infrastructure is being financed and built. As the rapid acceleration of AI and cloud computing drives global energy demand, this facility is designed to address the environmental footprint of high-performance computing. The data centre broke ground in July 2025 and is scheduled to be operational by the first quarter of 2027.
Hydrogen-Ready Innovation
A central feature of the 20-megawatt (MW) facility is its proof-of-concept initiative for on-site Solid Oxide Fuel Cell (SOFC) power generation. By integrating hydrogen-based energy solutions, DayOne aims to pioneer a lower-carbon power model for the data centre industry. The facility has already been awarded the Building and Construction Authority (BCA) Green Mark Platinum (Provisional) certification, reflecting its commitment to high energy-efficiency standards.
Beyond hydrogen fuel cells, the infrastructure will incorporate vertical building-integrated photovoltaics (BIPV) and advanced hybrid air and liquid cooling systems. These technologies are intended to mitigate the intense heat generation typical of AI-driven server clusters, allowing the facility to operate at higher efficiency levels than traditional air-cooled data centres.
Market Stakes and Institutional Support
The deal is considered one of the largest debt rounds of its kind, ranking above the 95th percentile of AI-linked debt deals in Singapore. Representatives from the participating banks emphasized that the investment reflects a broader strategy to support critical infrastructure that balances rapid digital growth with national sustainability targets.
“Demand for digital infrastructure is accelerating as AI and cloud computing continue to reshape economies across Asia,” said Han Kwee Juan, Group Head of Institutional Banking at DBS. “This is driving an increase in energy consumption and the need for more energy-efficient infrastructure.” The involvement of DBS, OCBC, and UOB underscores the role of local financial institutions in de-risking and scaling innovative green technologies within the urban environment.
