Newcastle, Australia. An ambitious plan to build a massive solar farm in remote northern Australia that would transmit energy by submarine cable to Singapore is a step closer after the Australian government granted environmental approvals for the 30 billion Australian dollar ($19 billion) project Wednesday.

Australian company Sun Cable plans to build a 12,400-hectare solar farm and transport electricity to the northern Australian city of Darwin via an 800-kilometer (497-mile) overhead transmission line, then on to large-scale industrial customers in Singapore through a 4,300-kilometer (2,672-mile) submarine cable.

The Australia-Asia PowerLink project aims to deliver up to six gigawatts of green electricity each year, which according to Australian Environment Minister Tanya Plibersek will "help turn Australia into a renewable energy superpower" and boost its economy.

"This massive project is a generation-defining piece of infrastructure," Plibersek said in a written statement on Wednesday. "It will be the largest solar precinct in the world – and heralds Australia as the world leader in green energy."

The project was initially backed by Australian mining magnate Andrew Forrest and Atlassian co-founder Mike Cannon-Brookes. The plans were highlighted during a state visit by then Singapore Prime Minister Lee Hsien Loong and Australian Prime Minister Anthony Albanese as part of a ' Green Economy ' agreement in 2022.

In January 2023, the project collapsed when Sun Cable entered voluntary administration due to a funding dispute between Forrest and Cannon-Brookes. By May of that year, a consortium led by Cannon-Brookes' Grok Ventures acquired the company, finalizing the takeover in September 2023.

SunCable Australia's managing director Cameron Garnsworthy said it was pleased to have cleared a major regulatory hurdle "and will now focus its efforts on the next stage of planning to advance the project towards a Final Investment Decision targeted by 2027."

The company said electricity supply would commence in the early 2030s.
