The three banks are acting as joint mandated lead arrangers, bookrunners, and green loan coordinators, with DBS also serving as facility and security agent.
What's the endgame? The loan funds a 20MW facility in western Singapore that broke ground in July 2025 and should be operational by Q1 2027. It is expected to be Singapore's first data centre with on-site Solid Oxide Fuel Cell power generation, part of a proof-of-concept exploring hydrogen-based energy.
Green by design. Structured under internationally recognised Green Loan Principles, the facility will use vertical building-integrated photovoltaics and hybrid air and liquid cooling. In December 2025, it achieved BCA Green Mark Platinum (Provisional), the highest rating from Singapore's Building and Construction Authority under its Green Mark for Data Centres Scheme.
Why now? Demand for digital infrastructure is surging, driven by artificial intelligence, cloud computing, and 5G. "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.
By the numbers. At $414.7 million, this ranks among the largest debt rounds in its class — above the 95th percentile of AI-linked debt deals in Singapore across all time, based on a sample of 217 comparable rounds.
The bigger footprint. Founded in 2022, DayOne has expanded across Asia and Europe, with a presence in Singapore, Malaysia, Indonesia, Thailand, Japan, Hong Kong SAR, Finland, and Spain.
The signal: As AI drives up energy consumption, lenders are backing infrastructure that pairs capacity with sustainability. "Digital infrastructure is becoming a strategic asset that underpins economic competitiveness," said Edmund Leong of UOB — and Singapore is positioning itself to lead the region's green financing of it.
