About Sun Cable
Sun Cable is an Australian-founded, world leading renewable energy company, developing solar energy infrastructure projects that will power Australia and the Indo-Pacific region with competitively priced, dispatchable, high capacity renewable electricity.
Sun Cable’s flagship project is the AUD $30B Australia-Asia PowerLink (AAPowerLink). Solar energy will be harnessed and stored at one of the worlds largest solar farm and battery systems in the Barkly region in the Northern Territory of Australia, for 24/7 dispatch to Darwin and Singapore via a 5,000km high voltage direct current (HVDC) transmission system.
Sun Cable’s energy projects will position the Northern Territory as the world leader in intercontinental transmission of renewable electricity. The project will stimulate the growth of a renewable infrastructure industry in the NT. Initial modelling indicates that the project will invest AUD $8B in Australia during the construction phase, with the majority spent in the NT, generating significant opportunities for NT workforce and industry participation across the construction and operational phases.
The provision of 800MW of electrical capacity to the Darwin region will facilitate the electrification of new and existing industries, supporting large-scale economic development, whilst reducing greenhouse gas emissions.
The $30+ billion project will herald the start of a new renewable export industry in the Northern Territory, and harness the Territory’s natural competitive advantages.
Acknowledgement of Country
Sun Cable respectfully acknowledges the traditional custodians throughout Australia and pays respect to their elders past and present.
We are committed to ongoing engagement with key Indigenous stakeholders, inclusive of Traditional Owners, Communities Groups and Land Councils, government, business and the broader community to maximise the opportunities of the AAPowerLink to the communities and people in the NT. We are working to develop an industry exemplar Sun Cable Indigenous Benefits Legacy, focusing on sustainability and intergenerational benefits.
The Australia-Asia PowerLink (AAPowerLink), a high-capacity solar generation, storage and transmission system that will transmit 3.2GW of 24/7 renewable electricity from the Barkly Region of the Northern Territory to Darwin and Singapore.
Construction is expected to take four to five years and is proposed to start after financial close in late 2023.
The AAPowerLink project the following key infrastructure:
- Solar precinct covering 12,000 hectare that generates 17-20 GWp from the solar PV arrays with a 36-42 GWh of energy storage to enable 24/7 dispatchable electricity, at Powell Creek near Elliot in the Barkly Region of the Northern Territory, Australia.
- Approximately 800 km of scalable 3.2-6.4 GW Overhead Transmission Line (OHTL) from the Powell Creek Solar Precinct to Murrumujuk, approx close to 35 km north-east of Darwin.
- Darwin Converter Site including Voltage Source Converters (VSC), energy storage and network connection to supply up to 800 MW of renewable electricity to the Darwin region.
- Cable Transition Facilities to enable transition of power cables between land and sea.
- Subsea cable system extending approximately 4,200 km from the Darwin Converter Site to Singapore with approximately 2.0 GW of capacity leaving Darwin.
- Singapore Converter Station including a VSC, grid interconnection and energy storage to supply the Singapore grid.
Sun Cable key milestones
Outlined below are key milestones and achievements of Sun Cable and the AAPowerLink project. This progress is working towards supporting positive outcomes for the territory and its communities.

- February 2021 - Infrastructure Australia Priority Listing
- September 2021 - Announcement of Support from Indonesia
- October 2021 - Formed the Integrated Project Delivery Team (IPDT), a global consortium of industry leaders to deliver the AAPowerLink
- November 2021 - Established the Territory Research Park (TRP) at site in Powell Creek to conduct research and testing, directly investing in the Northern Territory Economy and hiring local workforce.
- March 2022 - Lodged their Environmental Impact Statement (EIS) for the AAPowerLink project to the Northern Territory Environmental Protection Agency.
- March 31, 2022, The Northern Territory Government issued a Bill to make special provision in connection with the Australia-Asia PowerLink Project to ensure certainty of the project through dis-applying sections of the Crown Lands Act 1992.
- March 2022 - completed a AUD210 million Series B capital raise with existing shareholders to fund the development work of the AAPowerLink and progress the Company’s portfolio of multi gigawatt generation and transmission projects.
Solar Array Assembly Facility
5B is one of Sun Cable’s technology partners, which shares a vision of developing technology through innovation to rapidly scale solar PV generation. The partnership is focused on the MAVERICK system, a prefabricated solar array technology designed by 5B which is space-efficient for transport and it is conducive to automated factory assembly and rapid field deployment.
Sun Cable is working with 5B to customise the design of the MAVERICK to best suit the transport, deployment & generation needs of giga-scale solar farms like the AAPowerLink Solar Precinct. Utilising the MAVERICK system and automated production line engineering, we intend to establish the Solar Array Assembly Facility (Facility) at East Arm in Darwin. The Facility will potentially supply the AAPowerLink project.
The Facility, once fully operational, will benefit the Northern Territory through investment, jobs and a new long term industry. These ongoing operational activities have the potential to substantially scale up over time.
Middle Arm Battery
Sun Cable is developing the Middle Arm Battery (MAB) project which is a utility scale battery, with an installed capacity of 50MW scalable to 200MW, that will provide network support and ancillary services to the Darwin-Katherine Integrated System (DKIS), and facilitate further integration of local utility scale solar farms. Initially, this will be a standalone project, aiming to achieve commercial operations in 2023, though later it will connect to the broader AAPowerLink system. A connection application has been submitted to Power & Water Corporation and modelling of the system integration is well advanced.
The AAPowerLink will deliver significant strategic, economic and social benefits to the regions in which it is developing.
- AUD8 billion in investment in Australia during the four year construction period, with most spent in the Northern Territory
- 1,750 direct construction jobs in the Northern Territory
- 350 long-term operational jobs in the Northern Territory, for the 70 year life of the project
- A Territory Benefits Plan to optimise the strategic, economic and social benefits from the project during construction and operation
- The optimisation of contracting and procurement opportunities for Territory businesses
- Targets and strategies to achieve first class Indigenous participation
- Skills training and education support to develop career path-ways and multigenerational employment opportunities
- Supply of 800MW of 24/7 renewable energy to the Darwin region. This will decarbonise existing industries and attract the development of new green industries
- The provision of 800MW of green electricity will abate 2.5 million tonnes of CO2e per year in the NT. This is the equivalent of taking 4.9 million Australian cars off the road for one year or the annual electricity used by over 2.5 million Australian homes
- To create a Centre of Excellence for Renewable Energy in the NT, which will facilitate knowledge sharing, research and development and expertise development in the region
