Equinix opens $290m SG6 data centre in Singapore, its sixth, built for AI liquid cooling

US data-centre operator Equinix announced on November 6 that it has opened SG6, its sixth International Business Exchange (IBX) data centre in Singapore, backed by an initial investment of approximately $290 million, adding capacity for artificial intelligence, cloud and enterprise workloads.

The first phase of SG6 provides 8 MW of capacity and about 1,550 cabinets, with the site designed to support up to 20 MW of IT load when fully built out. The facility uses direct liquid cooling and proprietary cooling-array technology to handle the heat of high-density AI training and inference workloads, targets a power usage effectiveness (PUE) of 1.20, and has received Green Mark Platinum certification from Singapore's Building and Construction Authority.

First Equinix facility under the new allocation framework

SG6 is the first Equinix facility developed under Singapore's Data Centre Call for Application framework, through which the government allocates new data-centre capacity on the basis of resource efficiency and economic value. Equinix said its Singapore data centres have maintained 100% renewable energy coverage since 2020; SG6 also uses rooftop and facade solar panels, rainwater harvesting and NEWater in its cooling systems.

Equinix also plans to open a Co-Innovation Facility at SG6 in 2027 in partnership with the National University of Singapore, to research liquid cooling, cognitive digital twins and battery energy storage to improve data-centre sustainability and energy efficiency.

Singapore is one of the most connected markets in Asia-Pacific; SG6 opens as demand for AI infrastructure surges and the industry grapples with the triple bottleneck of compute, power and cooling.
