Australia-ASEAN Power Link Project

Proponent: Sun Cable Pty Ltd

Overview

Sun Cable Pty Ltd is proposing to establish a large-scale solar farm and energy storage facility in the Barkly region, NT, with power exported via a high-voltage direct current transmission network to Middle Arm peninsula, Darwin, and then sub-sea cable through Darwin Harbour and NT, National and International waters to Singapore. The proposal comprises:

  • a solar farm precinct (up to 12 000 hectares in area) including battery and ancillary infrastructure in the Barkly region of the NT, approximately 40 km southwest of Elliott
  • a high voltage, direct current (DC) overhead power transmission line (located mainly within the existing Alice Springs to Darwin railway corridor) from the solar farm to Middle Arm peninsula in Darwin, approximately 750 km to the north
  • up to two voltage source converters located at Middle Arm peninsula to convert power from DC to alternating current (AC) for connection to the Darwin-Katherine Integrated System, and a point to point link from Darwin to Singapore.
  • a land-sea joint station at Middle Arm peninsula to transition the high voltage cables from onshore to offshore
  • a subsea high voltage DC cable and fibre optic cable network that will extend approximately 3750 km from Darwin to Singapore, via Indonesia, with approximately 106 km of the cable proposed for NT waters.
