Australia-Asia Power Link

The Australia–Asia Power Link (AAPowerLink) is a proposed electricity infrastructure project that is planned to include the world's largest solar plant, the world's largest battery, and the world's longest submarine power cable.

Initial plans forecast that a new solar farm in the Northern Territory of Australia would produce up to 20 gigawatts of electricity, most of which would be exported to Singapore, and at a later point Indonesia, by a 4,300 km (2,700 mi) 3 GW HVDC transmission line. A large battery would store energy in order to level energy availability as sunlight varies throughout the day. AAPowerLink has been developed by an Australian company Sun Cable, initially backed by Andrew Forrest and Mike Cannon-Brookes. It was projected to begin construction in mid-2023, with operation starting in early 2026 and completion by late 2027, and estimated to add A$8 billion to the economy of the Northern Territory.

The project collapsed in January 2023, after Sun Cable was placed into voluntary administration following a disagreement between Forrest and Cannon-Brookes about the need to put more funding into the venture. In May 2023, a consortium led by Cannon-Brookes' Grok Ventures won the bid to acquire Sun Cable, with the takeover finalised on 7 September 2023. The revised plans involve supplying electricity to Darwin by 2030, and to Singapore a few years thereafter. Eventually the solar farm would produce six gigawatts of power.
