Equinix has opened SG6, its sixth data centre in Singapore, with an initial investment of US$290 million.

Designed for AI workloads, the facility also features tighter energy and water efficiency.

It will provide about 1,550 cabinets in its first phase and up to 20MW of IT capacity when fully built out.

SG6 is Equinix’s first facility developed under Singapore’s Data Centre – Call for Application process, which ties new capacity to national sustainability requirements.

“Singapore is one of our most important markets globally, and our continued investment here is a testament to the central role it plays in the digital economy,” said Adaire Fox-Martin, Chief Executive Officer and President of Equinix.

SG6 features liquid cooling and proprietary cooling array technology that support high-density AI deployments and power-intensive GPU infrastructure. It is capable of achieving a Power Usage Effectiveness of 1.20 and is targeting BCA-IMDA Green Mark Platinum certification.

Solar panels on the rooftop and building facade will contribute to the facility’s renewable energy coverage. Water-saving measures include NEWater use and rainwater harvesting, with collected rainwater stored for cooling tower operations to reduce reliance on potable water.

Server equipment deployed at SG6 must carry a recognised energy efficiency certification or demonstrate equivalent performance, in line with Singapore’s SS 715:2025 standard.

Equinix’s Singapore data centres have maintained 100 percent renewable energy coverage since 2020. Four renewable energy power purchase agreements will bring its local renewable energy portfolio to a cumulative 215MWp by 2028.

NUS partnership

SG6 will house a Co-Innovation Facility developed with the National University of Singapore Energy Solutions Hub, targeted to open in 2027.

Work will focus on liquid cooling, cognitive digital twins and battery energy storage to give industry and academic researchers a place to test and scale technologies for more sustainable data centres.

“SG6 strengthens our ability to support customers as they scale across Asia-Pacific, providing the resilient, interconnected and sustainable infrastructure they need to accelerate innovation and capture new growth opportunities,” said Cyrus Adaggra, President of Equinix Asia-Pacific.
