DayOne, a Singapore-headquartered global data centre pioneer, today broke ground on its first data centre in Singapore.
The 20-megawatt (MW) facility spans about 40,000 square meters of gross floor area, with Phase One scheduled to be ready-for-service in 2026.
DayOne was awarded capacity under the Pilot Data Centre Call for Application (DC-CFA) by the Infocomm Media Development Authority (IMDA) and the Singapore Economic Development Board (EDB), enabling the development of this flagship site anchoring the successful execution of the Singapore-Johor-Riau Islands (SIJORI) regional strategy.
“This facility marks our commitment to Singapore as both home base and regional hub while highlighting our long-term vision to power Southeast Asia’s digital transformation with green infrastructure,” said Jamie Khoo, CEO of DayOne Data Centre.
Backed by strong public-private collaboration, we’re building infrastructure that is purpose-built for AI workloads, cloud computing and innovation,” said Khoo.
DayOne also signed up for two key strategic partnerships.
One is a long-term partnership with Sembcorp through a 10-year Power Purchase Agreement (PPA) to supply its facility. The energy will be backed by bundled renewable energy certificates (RECs), sourced locally or imported via grid-to-grid connection.
Additionally, DayOne launched a new research and development partnership with the National University of Singapore (NUS) to jointly explore innovative technologies that improve data centre efficiency and sustainability.
The partnership will support activities under the Sustainable Tropical Data Centre Testbed Phase 2.0 (STDCT 2.0), including pilot-scale testing of novel cooling solutions in tropical climates.
The DayOne facility supports Singapore’s broader ambition to add at least 300MW of data centre capacity over the near term, as outlined in the Digital Connectivity Blueprint, a government framework to enhance global digital linkages and ensure the sustainable growth of foundational infrastructure.
It also aligns with Singapore’s National AI Strategy 2.0, which emphasizes the development of robust compute infrastructure to support AI innovation, model training and adoption across sectors.
DayOne’s Singapore data centre forms part of DayOne’s larger ambition to support digital transformation across the SIJORI Growth Triangle and build a resilient, low-carbon digital backbone for Southeast Asia.
Established in 2022 and operating as an independent group since 2025, DayOne develops and operates data centres across Singapore, Malaysia, Indonesia, Thailand, Japan, Hong Kong, and other key markets.
