DayOne Data Centers, a Singapore-headquartered digital infrastructure company, has secured a four-year, S$530 million ($415 million) green loan from the Singapore banks DBS, OCBC and UOB to fund its first data center in the country.

In a statement on Tuesday, lender DBS said the facility can become Singapore’s first to generate power on site using hydrogen fuel cells.

The 20-MW facility is in the western part of Singapore. It broke ground in July 2025 and is expected to begin operating in the first quarter of 2027. The loan was structured under the Green Loan Principles, an international framework for environmentally focused lending.

DBS, OCBC, and UOB acted as joint mandated lead arrangers, bookrunners and green-loan coordinators, with DBS also serving as facility and security agent.

The data center can include on-site solid oxide fuel cell power generation as a proof-of-concept for hydrogen-based energy, which DayOne and the banks said would be a first for Singapore. It will also use vertical building-integrated solar panels and a combination of air and liquid cooling.

Han Kwee Juan, group head of institutional banking at DBS, said demand for digital infrastructure was rising as AI and cloud computing increased energy consumption. The financing can support more energy-efficient facilities, the executive added.

Elaine Lam, head of global corporate banking at OCBC, said innovative energy solutions would play a growing role in supporting digital infrastructure sustainably.

Founded in 2022, DayOne operates data centres across Asia and Europe, with a presence in Singapore, Malaysia, Indonesia, Thailand, Japan, Hong Kong, Finland and Spain.
