DayOne breaks ground on first Singapore data centre to trial hydrogen-based power generation
It also signs power purchase agreement with Sembcorp Power, by which facility will be fully powered by renewable energy
[SINGAPORE] DayOne Data Centers Singapore is developing the nation’s first data centre to pilot on-site hydrogen-based power generation.
The Singapore-based company broke ground for the 20 megawatt data centre on Friday (Jul 25). The artificial intelligence-ready facility, with a gross floor area of approximately 40,000 square metres, is located within the Jurong East Data Centre Cluster. This is DayOne’s first data centre in the Republic.
The facility will be fully powered by renewable energy through a power purchase agreement with Sembcorp Power. DayOne is also partnering the National University of Singapore on a sustainable tropical data centre testbed. (* see amendment note below)
Hydrogen could supply half of the Republic’s power needs by 2050, according to the National Hydrogen Strategy released by the Ministry of Trade and Industry in 2022.
Responding to queries from The Business Times, DayOne said they invested S$350 million to develop the data centre, and expect to generate over 200 jobs from the facility.
DayOne was one of four data centre operators selected by the Singapore Economic Development Board and Infocomm Media Development Authority for the pilot Data Centre – Call for Application (DC-CFA) exercise in 2023.

The other data centres selected for the DC-CFA were Equinix, Microsoft, and a tie-up between AirTrunk and ByteDance.
DayOne was formerly the international arm of Chinese data centre firm GDS. It was established in 2022 and began operating as an independent group in 2025.
“This facility marks our commitment to Singapore as both (a) home base and regional hub, while highlighting our long-term vision to power South-east Asia’s digital transformation with green infrastructure,” said DayOne chief executive officer Jamie Khoo in a statement.
The Singapore data centre forms part of DayOne’s larger ambition to support digital transformation across the Singapore-Johor-Riau Islands Growth Triangle.
DayOne secured RM15 billion (S$4.6 billion) in dual-tranche green financing to support capital expenditure to develop its Johor data centres. It also operates data centres in markets such as Indonesia, Thailand, Japan and Hong Kong.
