Equinix Puts $290 Million Into Singapore Data Center SG6

Equinix has spent $290 million on the first phase of SG6, its sixth International Business Exchange data center in Singapore, which opened on November 6 and is built to serve artificial intelligence, cloud and enterprise workloads. The initial phase delivers roughly 1,550 cabinets. The site is designed to support up to 20 megawatts of IT load once fully built out.

The US-based operator announced the opening on November 6. SG6 holds a particular distinction: it is the first Equinix facility developed under Singapore's Data Centre Call for Application framework, the government mechanism that allocates capacity to projects judged on resource efficiency and economic value. Equinix won its slot in a competitive process, not an open market.

What does SG6 actually offer?

The facility is engineered for high-density computing, including AI training and inference, and supports direct liquid cooling — a technology that matters as AI chips push per-rack power beyond what air cooling handles well. Equinix said SG6 targets a power usage effectiveness (PUE) rating of 1.20, meaning roughly 1.2 watts consumed for every watt delivered to IT equipment. That figure, if achieved, would place it among the more efficient facilities in a hot, humid climate where cooling costs typically run high.

The building has received Green Mark Platinum certification from Singapore's Building and Construction Authority. Equinix said it will use solar panels, NEWater — Singapore's treated wastewater — and rainwater harvesting systems.

The company has also secured renewable energy through a Singapore solar power purchase agreement announced in August, targeting 215 megawatt-peak. That supply is expected to begin feeding the grid in 2027. In plain terms: SG6 opens now, but its clean-energy backing arrives about a year later.

How does it fit Equinix's network?

SG6 connects to Equinix's existing Singapore data-center network and its digital services platform, letting customers link infrastructure across clouds, networks and enterprise systems. With this opening, Equinix operates more than 270 data centers globally, six of them in Singapore.

Equinix is also pairing the facility with research. It is working with the National University of Singapore on an energy solutions hub intended to test technologies for more efficient data-center operations. A co-innovation facility planned at SG6 is expected to begin operating in 2027, according to Equinix. The collaboration will focus on energy efficiency, thermal management and sustainable infrastructure.

Why Singapore's reopening matters

The SG6 opening follows Singapore's selective return to new data-center development. The government had tightened capacity growth to address power and land constraints, making new approvals scarce and conditional. SG6's existence is proof Equinix cleared that bar — but the framework itself limits how fast the company, or any rival, can add capacity in one of Asia's most connected markets.

The caveat sits in the timeline. The $290 million covers only the initial phase, the renewable supply starts in 2027, and the co-innovation facility opens in 2027 as well. Equinix's sustainability claims for SG6 rest partly on commitments that have not yet been delivered. The takeaway: Singapore has reopened its data-center market, but on its own terms — and Equinix is now betting $290 million, with more phases to come, that those terms favor it.
