Singtel unit Nxera opens Tuas data center

Singtel’s data center arm Nxera has opened DC Tuas, Singapore’s highest power-density and most energy-efficient multi-tenanted data center with 58MW of AI-ready capacity.

The facility increases Nxera’s total capacity in Singapore to 120MW and supports higher-density AI workloads with the largest direct-to-chip liquid-cooling deployment.

Over 90% of the space was pre-committed before launch.

DC Tuas is integrated with a cable landing station, offering low latency and high reliability for mission-critical applications.

The data center meets the highest Green Mark Platinum standards awarded by Singapore’s authorities and incorporates solar power, rainwater harvesting, and other sustainability features, achieving a PUE of 1.25.

The facility is part of Nxera’s broader expansion plans in Asia, with additional capacity in Batam and Johor expected later this year.

The expansion aims to support Singapore’s position as a regional AI hub and enhance digital infrastructure resilience.

🧠 Food for thought

Implications, context, and why it matters.

Singapore’s strict regulations are shaping the data centers of tomorrow

Nxera’s new facility responds to Singapore’s tightly controlled data centre market.
Singapore ended a multi-year pause on new data centers, then launched the Green Data Centre Roadmap. The plan aims to unlock 300MW of added data centre capacity in the near term through higher energy efficiency at existing sites, with future capacity allocations tied to sustainability and economic value 1.
Green Mark Platinum certification and a Power Usage Effectiveness (PUE) of 1.25 align the site with Singapore’s 10-year target of PUE 1.3 at 100 percent IT load. That performance can help Nxera compete for future capacity allocations in a power-constrained nation 1.

Singapore’s limits are influencing a regional shift in data centre design and deployment

Tough energy rules make Singapore a proving ground for sustainable AI infrastructure.
AI’s heavy power draw is speeding up adoption of large-scale direct-to-chip liquid cooling.
This pull lifts demand for specialized green tech suppliers, plus it offers a template for space- and power-constrained cities managing AI growth 2.
These constraints also support a more regional buildout, with Johor and Batam emerging as data centre hubs alongside Singapore 3.
