Australia-ASEAN Power Link (AAPL)

Company Overview

Sun Cable is an Australian-founded, world leading renewable energy company. Thier vision is to harness Australia’s high-quality solar resource and power the Indo-Pacific region with competitively priced, dispatchable, high volume renewable electricity.

Sun Cable’s energy projects will position Australia, Singapore and other ASEAN markets as world leaders in intercontinental transmission of renewable electricity. This infrastructure will facilitate the electrification of new and existing industries, supporting large-scale economic development whilst reducing greenhouse gas emissions.

Project Overview  - Australia-ASEAN Power Link (AAPL)

The Australia-ASEAN Power Link (AAPL) is the integration of technologies to establish a solar energy infrastructure network that will provide the Northern Territory and Singapore with competitively priced, dispatchable, high volume renewable electricity. It includes a;

  • 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 solar farm to Darwin, connecting to the Darwin-Katherine Interconnected System (DKIS) and proposed Middle Arm Battery.
  • 3750km subsea HVDC cable system to Singapore

Project Benefits

The 70+ year, AUD 26 billion project will create approximately 1500 jobs during construction and 350 jobs during operations. It will inject $8 billion into the Australian economy, with a majority spent in the NT, and generate over AUD2.3 (2021 Real) billion in exports per annum. 

The provision of renewable electricity to the NT will support the establishment of sustainable development precincts and power new low emissions manufacturing businesses.

The potential for large-scale solar generation to transform the energy landscape in Northern Australia was included in Infrastructure Australia’s Annual Infrastructure Priority Initiative List in February 2021. 

Sun Cable has engaged Darwin Company, EcOz, to prepare an Environmental Impact Statement for its Australia-ASEAN Power Link (AAPL).

Sun Cable is preparing a Territory Benefits Plan (TBP) to optimise the social and economic benefit to the region from their activities. Elements of the TBP include NT procurement, Aboriginal participation and NT employment and training.

The company previously lodged a Development Application for its proposed battery and converter station on Channel Island Road, Middle Arm, which was approved in 2020.

Middle Arm Battery Project

The Middle Arm Battery project is an early works package that will later form part of the Sun Cable Australia-ASEAN Power Link (AAPL) project.

The project is proposed to be sited east of the existing Weddell Power Station, with an installed capacity of 50MW scalable to 200MW. The project is designed to provide active power and ancillary services to the Darwin-Katherine Integrated System.

The project is scheduled to commence commissioning in late 2022.

Solar Array Manufacturing Facility 

Sun Cable has received Development Consent from the Development Consent Authority for the first phase of a proposed solar array manufacturing assembly facility in Darwin.

This is an important step in the ongoing development of the Australia-ASEAN Power Link (AAPL); a solar energy infrastructure network that will provide Darwin and Singapore with competitively priced, dispatchable, high volume renewable electricity from 2026 and 2027 respectively.

The manufacturing facility will pilot a semi-automated production line, manufacturing Maverick solar array systems for supply to industrial and utility scale solar farms across Northern Australia.

The Maverick system has been designed by Australian company, 5B. A Maverick is an array of solar panels that is pre-fabricated so it can be easily transported and installed onsite. The establishment of this facility in Darwin will provide opportunities to supply future solar projects in the NT.

Phase two of the development will expand the facility to manufacture Maverick solar array systems for the AAPL, and establish a logistics and distribution centre to transport material and equipment by rail to Sun Cable's proposed solar farm, near Elliott in the Barkly Region of the Northern Territory. Phase 2 of the facility will be subject to a separate approval process.

The architectural design has been prepared by Darwin based company Bennett Design and the development application was prepared by Darwin town planning company, MasterPlan.

The facility is proposed for the East Arm Business Park managed by the Land Development Corporation. The location was chosen due to its proximity to Darwin Port and access to the Alice Springs to Darwin Railway.

An EOI process will be conducted to select a project delivery partner for the Factory.

Sun Cable is committed to maximising local industry and Indigenous participation and will continue to communicate via the ICN Gateway platform throughout the course of the project. To ensure you receive all correspondence regarding this project, please register your interest below.
