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.
