Equinix SG6 Opens in Singapore With 8 MW and 1,550 Cabinets

Equinix opened SG6, its sixth data center in Singapore, on Nov. 6, with an initial investment of about $290 million, 8 MW of first-phase capacity and room for up to 20 MW of IT load.

The company said in its release that the first phase delivers approximately 1,550 cabinets. Upon full build-out, SG6 will offer up to 20 MW of IT capacity, though Equinix gave no date for reaching it.

Equinix says SG6 is designed for a power usage effectiveness (PUE, total facility energy divided by IT energy) of 1.20 and targets Green Mark Platinum certification. eWeek noted that 1.20 is a design target, not a measured operating result.

What SG6 Offers at Opening

Voltgrid's arithmetic on the release's own figures: 8 MW across roughly 1,550 cabinets averages about 5 kW per cabinet, an average and not a rack specification. The first phase is 40% of the 20 MW planned. At the design PUE, a fully built 20 MW of IT load would imply about 24 MW of total facility power, before any real-world drift from the target.

Equinix describes proprietary cooling array technology and liquid-cooling capability for power-dense GPU hardware. Rooftop and facade solar panels, NEWater and rainwater harvesting for cooling towers complete the efficiency package, according to Equinix's Singapore release.

Singapore's Efficiency Rules and Power Limits

SG6 is the first Equinix site built under Singapore's Data Centre - Call for Application (DC-CFA) process, which selected four projects after Singapore lifted its three-year data-center moratorium in 2022, according to Equinix's Singapore release. Customer servers at SG6 must carry a recognized energy-efficiency certification or show equivalent efficiency under the SS 715:2025 standard, Equinix said.

Capacity here is tightly rationed. As eWeek reported, the government provisionally allocated 200 MW in August across Equinix, Digital Realty, Keppel Data Centres and ST Telemedia Global Data Centres, 50 MW each under the second call. Equinix's 50 MW award is for a separate Jurong Island project, so it does not add to SG6's 20 MW. The grid side of that squeeze is covered in Voltgrid's earlier reports on Singapore's grid-based renewable claims and on peak demand that could reach 13 GW by 2031.

On power sourcing, Equinix says its Singapore sites have had 100% renewable energy coverage since 2020 and that four renewable power purchase agreements there are expected to build a cumulative 215 MWp portfolio by 2028. That figure is generation capacity, not SG6's IT load, and coverage does not mean renewable electricity every hour.

What is not confirmed yet

Equinix has not named SG6 customers, disclosed pricing, or said how much of the 8 MW is already contracted. eWeek noted that "AI-ready" does not mean GPUs or managed AI services are included. The 1.20 PUE and the Green Mark Platinum rating remain a design aim and a target, and no date has been given for the move from 8 MW to 20 MW.

A Co-Innovation Facility with the National University of Singapore's Energy Solutions Hub is targeted for 2027 at SG6, to trial liquid cooling, digital twins and battery energy storage in a working data center.
