PLANS to use a 4,200-kilometre power cable to send clean energy from Australia to Singapore are no longer commercially viable, according to one of the project’s billionaire investors.

A review of Sun Cable’s A$30 billion (S$28 billion) proposals concluded the project should ditch an ambition to export electricity and focus instead on using a huge planned solar and battery facility to feed green industries at home, according to Andrew Forrest’s Squadron Energy unit — which holds a 25 per cent stake in the developer.

Sun Cable entered into voluntary administration last week after a disagreement between Forrest and tech tycoon Mike Cannon-Brookes over funding and the plans to send clean power overseas. Forrest is considering a potential offer for the company, a person familiar with the details said last week.

“Squadron Energy continues to believe in the vision for a game changing solar and battery project in the Northern Territory’s Barkly region,” Squadron chairman John Hartman said. The unit — Australia’s biggest renewables developer — is focused on helping the country “become a green energy exporting superpower by generating renewable energy to produce green hydrogen and green ammonia”.

There has been widespread industry scepticism over the wild ambition of the Sun Cable plans, which include proposals to build the world’s largest solar farm and a giant battery facility and then export electricity to Singapore via a high-voltage undersea cable that’s more than five times longer than major existing connectors like the Norway-to-UK North Sea Link.

Forrest is seeking to transform his Fortescue Metals Group, a key global iron ore supplier, into a major producer of green metals and an exporter of clean hydrogen. Forrest’s Fortescue Future Industries aims to start producing 15 million tons a year of green hydrogen from renewable generation by 2030. BLOOMBERG
