Billionaires invest $46m in Australian solar farm connecting to Singapore

The 4,500km transmission network is set to be the world’s longest high voltage cable.

Reuters reported that two Australian billionaires have invested $46.38m (A$50m) to jumpstart a megaproject to supply solar power from northern Australia to Singapore via the world’s longest subsea high voltage cable, the project’s boss said.

Sun Cable, which is leading the roughly $20.41b (A$22b) project, raised the money from the private family fund of Atlassian co-founder Mike Cannon-Brookes and mining magnate Andrew Forrest’s private company Squadron Energy.

Sun Cable plans to build a 10GW solar farm in Tennant Creek in the Northern Territory, a 22 GWh battery storage facility and a 4,500km transmission network to Singapore. All three elements would be the biggest of their kind in the world.

The Australia Singapore Power Link would supply a fifth of Singapore’s power needs, helping to ease the island nation’s dependence on imported liquefied natural gas (LNG), according to Sun Cable’s website.

Every quarter, SBR lands on the desks of the founders, CFOs, and directors running Asia's most consequential companies. Every day, they open our newsletter and read our website. It's a room that took twenty years to build — and it's the one most of our partners are trying to get into.

The good news is that the door is open. We work with companies on thought leadership articles, sponsored content, industry summits across Southeast Asia, regional awards programmes, podcasts, and media placements in print and digital. The shape of the right partnership depends on what you're trying to do, which is why we'd rather start with a conversation than send a rate card.

If you have something this room should know about, tell us. We'll tell you honestly whether we can help, and how.

No rate cards until we understand the brief. It's a better use of everyone's time.
