Australia-ASEAN Power Link

Australia-ASEAN Power Link

The Australia-ASEAN 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 10 gigawatt solar farm and 20 to 30 gigawatt hour battery storage facility near Tennant Creek, Northern Territory.

The project would supply dispatchable renewable energy to Darwin and Singapore via a 4,500 kilometre high-voltage direct current transmission network extending from the solar farm and storage facility to Singapore.

Integration of the project with the developing ASEAN power grid is being assessed in the development phase.
