Hitachi, SIT to build hybrid AC/DC power testbed for data centres

Rack-level trial to run on SIT microgrid at Punggol campus.

Hitachi and the Singapore Institute of Technology will co-develop a hybrid AC/DC rack-level power distribution testbed for data centres, which the partners said is a first-of-its-kind rack-level testbed in Singapore.

The testbed will interface with SIT Punggol Campus’ multi-energy microgrid, which the release described as the first to be constructed on a university campus in Southeast Asia, integrating solar photovoltaic systems and other distributed energy resources for campus-wide monitoring and optimisation.

The partners stated that the campus will serve as a live test environment under SIT’s Living Lab Network, where they will deploy and evaluate hybrid AC/DC power solutions under real-world operating conditions.

They cited rising digitalisation and AI demand as drivers of increasing data centre energy consumption in Southeast Asia, with computing and cooling needs heightened by tropical climates.

The testbed will evaluate hybrid rack-level approaches, including higher-voltage DC distribution intended to improve efficiency and enable the integration of renewable energy, with findings expected to inform future data centre power architectures.

SIT students will also work with Hitachi’s R&D team on real-world assignments related to hybrid AC/DC systems and renewable integration.

If you've been wondering whether SBR could work for your company — yes, probably.

A lot of the companies we partner with started as readers. They'd been following our coverage for a while, saw their own customers and competitors in it, and eventually asked the obvious question: could we do something with you? The answer is usually yes. The shape of it depends on what you're trying to do.

The options are broader than most people assume — thought leadership articles, sponsored content, industry summits across Southeast Asia, regional awards programmes, podcasts, and media placements in print and digital. Some partners use one channel; most use a mix. We figure out the right combination by starting with your brief, not with our rate card.

So if the question has been on your mind, here's the easy way to ask it.

We'll tell you honestly whether we can help, and how. It's a better use of everyone's time.
