Singapore’s DayOne breaks ground on first data center in Singapore

This press release was issued by DayOne.

• DayOne signs Power Purchase Agreement with Sembcorp Power to enable 100% renewable energy for the new data center 
• R&D Collaboration with NUS to Drive Tropical Data Center Innovation

DayOne, a Singapore-headquartered global data center pioneer, today broke ground on its first data center 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 (RFS) in 2026.

The groundbreaking event also saw the signing of two key strategic partnerships for DayOne – a Power Purchase Agreement (PPA) with Sembcorp Power Pte Ltd, a wholly-owned subsidiary of Sembcorp Industries (Sembcorp) to power its data center where all operations will be fully covered with renewable energy, and a research and development partnership agreement with the National University of Singapore (NUS) to advance data center innovation as part of the Sustainable Tropical Data Center Testbed Phase 2.0 (STDCT 2.0) initiative.

The facility will feature green-powered high-density air-cooled Graphics Processing Unit (GPU) support, hybrid air and liquid cooling technologies. It is also expected to be Singapore’s first data center with on-site Solid Oxide Fuel Cell (SOFC) power generation, part of a pioneering proof-of-concept for hydrogen-based energy. By piloting SOFC, DayOne aims to accelerate the adoption of innovative green solutions, enhance diversification of energy sources for the data center industry, and support the city-state’s sustainability goals. Both LEED Platinum and BCA Green Mark Platinum (GMDC:2024) certifications will be applied for, aligning with the highest environmental and energy performance standards for data centers.

DayOne was awarded capacity under the Pilot Data Center 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. The award reflects confidence in DayOne’s advanced energy-efficient solutions and proven capabilities in delivering sustainable digital infrastructure.

The groundbreaking ceremony was attended by senior government and industry leaders, including Ms. Aileen Chia, Deputy Chief Executive, Infocomm Media Development Authority (IMDA); Ms. Seah Yueh Chinn, Vice President, Digital Industry Singapore (DISG); and Ms. Christine Wong, Assistant Chief Executive Officer, JTC Corporation. Also in attendance were Mr. Lim Ah Doo, Co-Chairman of DayOne; Ms. Jamie Khoo, CEO of DayOne; Mr. Koh Chiap Khiong, President & CEO, Gas and Related Services and CEO, Singapore, Sembcorp; Professor Lee Poh Seng, National University of Singapore (NUS); and other partners.

Long-term Partnership with Sembcorp to achieve 100% renewable energy

DayOne formalized 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. This strategic agreement marks a significant milestone in DayOne’s journey towards 100% renewable electricity, reinforcing its commitment to sustainability and clean energy adoption. This partnership lays the foundation for continued collaboration to support DayOne’s future growth and expansion.

R&D Partnership with National University of Singapore

Additionally, DayOne launched a new research and development partnership with the National University of Singapore (NUS) to jointly explore innovative technologies that improve data center efficiency and sustainability. The partnership will support activities under the Sustainable Tropical Data Center 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 center 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 center 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 centers across Singapore, Malaysia, Indonesia, Thailand, Japan, Hong Kong SAR, and other key markets.
