Equinix Opens $290 Million SG6 Data Center in Singapore

Equinix has opened SG6, its sixth International Business Exchange data center in Singapore, with an initial investment of about $290 million. The first phase delivers roughly 1,550 cabinets and about 8 MW of capacity. The site scales to 20 MW of IT capacity at full build-out, according to the company.

SG6 is the first Equinix facility built under Singapore's Data Centre Call for Application, or DC-CFA. That regime replaced a government pause on new data center construction. Singapore lifted the pause in 2022 and ran a pilot call in which operators compete for capacity on efficiency and other criteria. In July 2023, the government provisionally awarded about 80 MW across four winners: Equinix, GDS, Microsoft and an AirTrunk-ByteDance consortium.

What does the opening actually deliver?

The numbers merit scrutiny. SG6 opens at about 8 MW of its eventual 20 MW. Equinix has not published a timeline for the remaining build-out. The $290 million figure covers initial investment, not the full site cost.

The design targets are specific. The facility is designed for a power usage effectiveness of 1.20. It supports liquid cooling for dense GPU racks. It targets Green Mark Platinum certification, Singapore's top efficiency rating. Senior Minister of State Tan Kiat How attended the opening, according to the Economic Development Board.

The sustainability commitments come with partial verification. Equinix says its Singapore data centers, where it has operated since 2002, have had 100% renewable coverage since 2020. SG6 adds rooftop and facade solar panels. It uses NEWater, Singapore's recycled water supply, and harvested rainwater. A co-innovation facility with the National University of Singapore, due in 2027, will work on liquid cooling, digital twins and battery storage. That date sits three years out.

"Singapore is one of our most important markets globally," chief executive Adaire Fox-Martin said in the company's announcement.

How much capacity is still coming?

More allocations are in motion. In August, Equinix was one of four operators provisionally allocated 50 MW each in the second call, DC-CFA2. The others were Digital Realty, Keppel Data Centres and ST Telemedia Global Data Centres. Those awards remain provisional, not final.

The second-call sites carry conditions. They must be built in a Sustainable Data Centre Park on Jurong Island. The winners committed to power more than half their capacity with green energy. The agencies said they would review the need for a third call in 18 to 24 months, a window that leaves near-term supply constrained by design.

Is 20 MW competitive?

Scale is the caveat. At 20 MW, SG6 is small next to U.S. AI campuses. Equinix's Asia-Pacific president told CNBC last week that its typical enterprise sites run 30 to 60 MW. Singapore's allocation regime, which caps awards and ties them to efficiency metrics, effectively keeps individual facilities modest while total capacity grows through successive calls.

The commercial logic is still clear. Singapore remains a hub for enterprise interconnection, and Equinix now holds allocations in both DC-CFA rounds. Its 50 MW on Jurong Island, if confirmed and built, would more than double the SG6 footprint. Competitors hold the same allocation size there, so differentiation will depend on speed to build, green energy procurement and the efficiency scores the regime rewards.

Whether the third call arrives on schedule, and whether Equinix converts provisional awards into operating capacity ahead of Digital Realty and Keppel, will shape Singapore's data center market through at least 2027.
