Australia’s largest renewable energy infrastructure project aims to export solar power from Australia to Singapore while injecting billions of dollars into the economy and creating thousands of jobs.

The Australia-ASEAN Power Link (AAPL) will establish a solar energy infrastructure network that will provide Darwin and Singapore with competitively priced, dispatchable, high volume renewable electricity.

The project comprises:

  • 14GW solar farm and approximately 33 GWh battery energy storage located near Elliott, in the Barkly Region of the Northern Territory
  • 750km high voltage direct current (HVDC) transmission line from the site to Darwin, connecting the precinct to the Darwin-Katherine Interconnected System (DKIS) and proposed Middle Arm Battery
  • 3750km subsea HVDC cable system from Darwin to Singapore

Once complete, Sun Cable’s proposed Australian-ASEAN Power Link will establish Australia as a world leader in transmitting renewable electricity across continents. This will bolster our long-standing position as an energy exporting powerhouse. Full commercial operations of the AAPL will be in 2027.

The Australian Government formally recognised AAPL’s significance to the Australian economy in July 2020 by granting it Major Project Status. This gives it a single entry point for Australian Government approvals, project support and coordination and help with state and territory approvals.

The 70 year project is expected to create 1,500 Australian jobs during construction, 350 ongoing jobs in Australia, as well as indirectly supporting around 12,000 Australian jobs. It will inject $8 billion into the Australian economy and generate over $1 billion in exports per annum.

Underpinning the project is Australia’s world-class solar technology and high-tech manufacturing capability to export renewable energy on an unprecedented scale.
