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 4,500 km (2,800 mi) 3 GW HVDC transmission line. A large battery would store energy in order to level energy availability as sunlight varies throughout the day.^[2] 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,^[1] and estimated to add A$8 billion to the economy of the Northern Territory.^[3][4]

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.^[5][6] In May 2023, a consortium led by Cannon-Brookes' Grok Ventures won the bid to acquire Sun Cable,^[7] 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 6 gigawatts of power.^[8]
