Nxera opens high-density data centre as Singtel deepens push into AI infrastructure
Nxera launches Singapore’s largest AI-ready data centre as Singtel expands its digital infrastructure strategy across Asia.
Nxera, Singtel’s regional data centre business, has opened its largest and most advanced facility in Singapore, signalling a major step in the country’s push to expand artificial intelligence and cloud infrastructure. The new site, called DC Tuas, brings a new generation of high-density, energy-efficient computing capacity online at a time when demand for advanced data centre services is accelerating across Asia.

The facility delivers 58MW of AI-ready capacity and is positioned as Singapore’s highest power-density multi-tenanted data centre. More than 90% of its capacity was already committed before its official launch, pointing to strong interest from enterprise customers and hyperscalers rather than speculative projections. With DC Tuas now operational, Nxera’s total data centre capacity in Singapore reaches 120MW, strengthening its ability to support AI, cloud computing and high-performance workloads in a market where capacity remains limited.
High-density design and advanced cooling for AI workloads
DC Tuas has been built to support the extreme rack densities required by next-generation AI infrastructure. As a carrier-neutral, multi-tenanted facility, it hosts Singapore’s largest direct-to-chip liquid-cooling deployment, enabling customers to operate powerful graphics processing units more efficiently. Compared with traditional air-based cooling, the system improves heat extraction while reducing both energy and water consumption.
The facility reports a power usage effectiveness score of 1.25, which positions it among the most energy-efficient multi-tenanted data centres in Singapore and the broader tropical region. Power usage effectiveness is an industry metric that measures the ratio of total energy consumption to the energy used by IT equipment, with lower values indicating better efficiency. Achieving a low score is particularly challenging in hot, humid climates, where cooling systems account for a large share of power consumption.
Sustainability measures are integrated into the building’s design rather than added later. DC Tuas uses smart thermal management systems, high-efficiency electrical infrastructure and direct-to-chip liquid cooling to optimise performance. It also incorporates solar power, rainwater harvesting, condensate reuse and blowdown recovery to reduce reliance on potable water and lower its environmental footprint. The facility has received the highest Green Mark Platinum certification from Singapore’s Building and Construction Authority and Infocomm Media Development Authority, reflecting compliance with strict environmental standards.
Hyperconnectivity and strategic role in Singtel’s digital infrastructure
DC Tuas is also positioned as Singapore’s only hyperconnected data centre integrated with a cable landing station. The eight-storey, 120,000-square-foot facility provides direct access to both international and domestic networks, intended to deliver lower latency, greater reliability, and improved network performance for critical applications.
This integration strengthens Singtel Digital InfraCo’s broader infrastructure platform, which spans connectivity, subsea cables and data centres across the Asia Pacific region. As digital workloads become more latency-sensitive and distributed, proximity to network infrastructure is increasingly important alongside raw computing capacity.
Bill Chang, chief executive of Nxera and Singtel’s Digital InfraCo unit, described the opening of DC Tuas as a milestone in enabling sustainable AI innovation in Singapore. He highlighted that the ability to deploy high-density, compute-intensive workloads efficiently is becoming essential in a market where data centre capacity is constrained. While broader statements about reinforcing Singapore’s role as a global AI hub reflect strategic ambition, the technical characteristics of DC Tuas provide tangible support for large-scale AI deployment.
The launch comes amid significant consolidation in the data centre sector. Singtel and North American investment firm KKR are in the process of acquiring the remaining 82% stake in ST Telemedia Global Data Centres for about S$6.6 billion, according to regulatory filings and recent reports. The transaction would value the business at around S$13.8 billion, making it one of the largest data centre deals in Southeast Asia and highlighting the growing strategic importance of digital infrastructure. Once completed, KKR would hold roughly 75% of STT GDC, with Singtel retaining about 25%, subject to regulatory approvals and expected to close by the second half of 2026.
Regional expansion and long-term capacity growth
Beyond Singapore, Nxera is continuing to expand its footprint across Asia. Additional AI-ready capacity in Batam and Johor is scheduled to come online in the second half of 2026. Taken together, the company’s operational and pipeline capacity is expected to more than double from 200MW in 2026 to more than 400MW in the medium term.
This expansion assumes sustained demand growth and timely project delivery, and future disclosures on customer mix and utilisation rates will be needed to verify the pace of uptake. However, the high level of pre-commitment at DC Tuas suggests demand is substantial rather than speculative.
For Singtel and Nxera, the opening of DC Tuas reflects a broader shift in the data centre industry. Energy-efficient, AI-ready facilities are increasingly seen as critical infrastructure rather than niche assets. In Singapore’s case, such facilities are becoming foundational to supporting cloud services, enterprise digital transformation and the next wave of AI-driven innovation across the region.
