SunCable Manufacturing
SunCable is in discussions with global cable manufacturers to jointly develop, construct and operate an advanced high voltage (HV) cable manufacturing facility, with the AAPowerLink project from Darwin to Singapore as an anchor customer.
This multibillion-dollar investment in Australian advanced manufacturing will deliver enduring benefits for 40+ years. It will create around 800–1000 jobs during construction and more than 400 ongoing operational jobs.
Australia has abundant sunshine and wind. High voltage direct current (HVDC) cable enables the transportation of these renewable resources around the country and throughout the region, establishing Australia as a renewable energy superpower as well as an advanced manufacturing hub for critical supply chains.
This advanced cable manufacturing facility will be the first of its kind in the Southern Hemisphere, manufacturing HV transmission cables that are essential in the energy transition. These cables unlock renewables generation capacity, transmitting clean energy to industry, business, and our homes.
Community Information Sessions
SunCable is an Australian renewable energy company built on an ambition to harness the unbeatable potential of Australian sunshine. SunCable is considering the opportunity to build and operate an advanced marine cable manufacturing plant potentially at Bell Bay in Northern Tasmania.
We value the opportunity to engage directly with our communities and are planning Community Information Sessions in the Tamar Valley on 14 and 15 May 2024.
We will be at the Beaconsfield Community Hall from 11am to 12:30pm, and 6pm to 7:30pm, and at the Clarence Point Community Hall from 2pm to 3:30pm on Tuesday 14 May. On Wednesday 15 May, sessions will be held at the George Town Yacht Club from 2pm to 3:30pm, and 6pm to 7:30pm.
The sessions are ticketed and we have more sessions available if capacity is reached at the above, scheduled times.

Project Update
SunCable has been working with jurisdictions across Southeast Asia and Australia over the last two years, assessing potential sites for this advanced cable manufacturing facility.
As part of this process, we are progressing detailed studies and due diligence on a potential site in Bell Bay, Tasmania. Any final decision to progress development applications for this site will be made after initial community consultation.
Our criteria for potential sites include:

FAQs
How will this advanced cable manufacturing facility support the energy transition?
Net zero commitments from 139 countries are driving a significant increase in demand for wind and solar power, as renewable electricity forms the bedrock of the energy transition.
SunCable is on a mission to deliver reliable renewable energy across Australia and throughout the region, via its flagship AAPowerLink project.
AAPowerLink will require a 4,300km HVDC subsea cable system to connect Darwin with Singapore. SunCable is seeking to support Singapore’s objective of importing at least 4 GW from low-carbon sources by 2035.
SunCable is set to establish an advanced high voltage (HV) subsea cable manufacturing and testing facility, with AAPowerLink as an anchor customer.
HVDC cables connect renewable projects to the power grid, making them a key enabler of decarbonisation in economies around the world.
Why do we need this advanced cable manufacturing facility in Australia?
Development of a purpose-built manufacturing facility will help reduce global supply constraints of HVDC subsea cable. All existing advanced HVDC subsea cable facilities are in the Northern Hemisphere.
This facility will be a critical enabler of SunCable’s flagship AAPowerLink project, and the region’s decarbonisation goals. It will provide well-paid jobs in local communities, including over 800 construction roles and a further 400 in ongoing operations for more than 40 years.
What are the key features of the facility?
The facility will require a site of about 45 hectares with the following features:
- Buildings for the cable manufacturing production line, material storage, offices, and a car park
- A fully enclosed 180-200m tower where the insulation layer is applied to the conductor*
- A series of large platforms for storage of manufactured cable
- A jetty for mooring and loading cable-laying vessels
- Electrical infrastructure to accommodate grid connection
- Capacity to manufacture 1,200–1,600 kilometres of cable a year
*The tower enables the critical manufacturing step of conductor insulation to be performed vertically, where the polyethylene insulation layer is applied and cured in a perfectly circular manner around the conductor. The tower does not produce emissions and the entire cable manufacturing process has a very low emission profile.
What types of cable is SunCable planning to manufacture?
The advanced cable manufacturing facility will focus on 525 kV-640 kV HVDC subsea cable for the AAPowerlink project during its first four years of operation. It will then introduce product variants including HVAC submarine and HVDC land cables.
This facility will expand the supply of advanced HV subsea cable globally and will be a critical enabler for SunCable and other high-priority renewable generation and transmission projects across Australia and throughout the region.
How much cable do you need?
AAPowerLink needs two 4,300-kilometre HVDC subsea cables to transmit power to Singapore. The current global supply chain lacks the capacity to produce the 8,600 kilometres of cable required within the project timeframe.
The global energy transition is driving international and domestic demand for HV subsea cable. For example, the International Energy Agency estimates almost $US1 trillion of investment will be required to transform the Association of Southeast Asian Nations power sector.
Here in Australia, a rapidly growing pipeline of offshore wind projects, and the government backed Marinus Link between Tasmania and Victoria, will also need HV subsea cables.
How is the manufactured cable transported?
The finished cable is spooled onto turntables to be stored before transportation. The cable is directly loaded onto a purpose-built cable-laying vessel, with a loading time of 10-14 days. This vessel transports and installs the cable.
What is SunCable’s approach to stakeholder and community engagement?
SunCable has identified Bell Bay as a potential site, and will now move forward with early stakeholder and community consultation before any final decision is made.
SunCable will engage business, government, groups and individuals over the coming months and welcomes feedback.
