Australia-Asia Power Link

Detailed Planning
Australia-Asia Power Link

The Australia-Asia Power Link is a proposed project to be developed by Sun Cable, which will supply dispatchable renewable electricity to Darwin and the ASEAN region. The proposal includes the integration of a 17 to 20-gigawatt peak solar farm and 36 to 42-gigawatt hour battery storage facility near Tennant Creek, Northern Territory.

The project would supply dispatchable renewable energy to Darwin and Singapore via a 4,200-kilometre high-voltage direct current transmission network extending from the solar farm and storage facility to Singapore. The full transmission system will total approximately 5,000 kilometres in length.
