Nxera, Singtel Group’s regional data centre arm, has opened its largest and most advanced data centre to date, to support the growing demand from AI, cloud and high-performance computing workloads.
DC Tuas is designed as a next-generation, AI-ready facility, with 58MW capacity, making it Singapore’s highest power-density data centre. With this data centre, Nxera’s total data centre capacity in Singapore increases to 120MW. Over 90 per cent of DC Tuas’ capacity was already committed to customers ahead of its opening.
As a carrier-neutral, multi-tenanted data centre, DC Tuas hosts Singapore’s largest direct-to-chip liquid cooling deployment, which enables customers to deploy new AI infrastructure efficiently and at scale.
The cooling technology improves heat extraction while reducing energy and water consumption compared to traditional cooling methods.
“The ability to deploy higher-density, compute-intensive AI workloads sustainably, is increasingly critical for a strategic market where data centre capacity is constrained,” said Bill Chang, chief executive officer of Nxera and Singtel’s Digital InfraCo unit
DC Tuas strengthens network performance for mission-critical applications. The 120,000-square-foot, eight-storey, facility is Singapore’s only hyperconnected data centre integrated with a cable landing station, providing direct access to both international and domestic networks.
This integration enables lower latency, enhanced reliability and strong network performance for mission-critical and latency-sensitive workloads, while maintaining full carrier neutrality.
Sustainability is a core feature of DC Tuas’ design and operations. The facility meets the highest Green Mark Platinum standard awarded by Singapore’s Building and Construction Authority and Infocomm Media Development Authority (IMDA).
It incorporates smart thermal features, high-efficiency electrical systems and direct-to-chip liquid cooling optimised for Singapore’s tropical climate. Additional environmental measures include the use of solar power, rainwater harvesting, condensate reuse, and blowdown recovery.
As a result of these design choices, DC Tuas achieves a power usage effectiveness (PUE) of 1.25. That, according to Singtel, makes it the most energy-efficient multi-tenanted data centre in Singapore and the wider tropical region.
Beyond Singapore, Nxera is set to expand its footprint across Asia, with additional AI-ready capacity expected to come online in Batam, Indonesia and Johor, Malaysia in the second half of 2026. Operational and pipeline capacity is projected to more than double from 200MW in 2026 to over 400MW in the mid-term.
This momentum aligns with broader industry and policy developments in Singapore. Last month, ST Telemedia Global Data Centres (STT GDC) launched Southeast Asia’s first live testbed for High Voltage Direct Current (HVDC) to support high-density AI workloads, which can deliver up to 30 per cent energy savings.
Singapore already hosts one of the world’s densest data centre capacities, and IMDA had announced plans in 2024 to unlock 300MW of additional capacity under its Green Data Centre Roadmap.
