Australia-ASEAN Power Link

Renewable Electricity for Australia, Singapore and Indonesia


As an island nation, Singapore is reliant on imported Liquid Natural Gas for 95% of its electricity. This leaves Singapore's electricity consumers excessively exposed to the vagaries of global oil and gas pricing.

Sun Cable will produce approximately a fifth of Singapore's electricity through solar power, sourced from the Australian desert and transmitted via a High Voltage Direct Current (HVDC) cable. Australia's strong relationship with Singapore, its stable economy, political and legal framework, will ensure security of supply for Singapore. 

The 12,000 hectare solar array near Elliott in Australia's Northern Territory will be supported by battery storage. This will allow Singapore, and also the Northern Territory, to have a more diverse electricity supply, thereby increasing resilience and helping it meet its Paris Commitment greenhouse gas reduction targets. 

Community consultation will begin in late 2020.



Sun Cable is developing the Australia-ASEAN Power Link (AAPL), a major energy infrastructure project that will supply renewable electricity to Darwin and the ASEAN region. As the world’s largest dispatchable renewable electricity system, the AAPL is expected to be the first of many ‘sun-cables’.


The AAPL will integrate three technology groups - the world’s largest battery, the world’s largest solar farm, and a 4,500km high voltage direct current (HVDC) transmission system from the solar / storage facility to Darwin, Singapore and eventually Indonesia.


It will provide dispatchable renewable electricity to the Northern Territory and will supply up to 20% of Singapore’s electricity demand. 


By the end of 2027, Sun Cable’s AAPL will be able to provide a significant amount of renewable energy to the Northern Territory and export approximately $2 billion of solar energy per year to Singapore, connecting Australia into the ASEAN Power Grid. 


The AAPL has been awarded Major Project Status by the Australian Government, specifically Minister for Industry, the Hon Karen Andrews MP and Minister for Energy, the Hon Angus Taylor MP.  Major Project Status is the Commonwealth Government’s recognition of the strategic significance of a project to Australia. It provides projects with support from the Major Projects Facilitation Agency, which acts as a single entry point for Commonwealth Government approvals, project support and coordination.

AAPL received Major Project Status from the Northern Territory Government in June 2019.

In the context of the fundamental energy transition the global economy is undergoing, and in particular the significant demand for renewable energy in the Indo Pacific, Sun Cable is developing world-leading projects that will help meet the region’s renewable energy needs for decades to come.  

Sun Cable was founded in 2018 by the lead executives David Griffin, Mac Thompson and Fraser Thompson. 

Sun Cable concluded a significant capital raise in November 2019, which included lead investment from Mike Cannon-Brookes's Grok Ventures and Andrew Forrest's Squadron Energy. 

Mr Cannon-Brookes said. "In a carbon-constrained world, Australia should be a winner. This is a massively exciting project with world-changing potential. We have the resources, the ingenuity and the drive to get it done - we just have to put it all together. If we nail this, we can build a new export industry for Australia, create jobs and set our economy up for the future."


Andrew Forrest said: “Australia has the potential to be at the centre of our region’s transition to clean energy, a serious priority for our country. This presents the Australian economy with enormous opportunities not just for reducing emissions but also for the economic march of our nation and global competitiveness. Sun Cable’s Australia-ASEAN Power Link project has the potential to be an important part of this nation-building journey.”

David Griffin

Chief Executive Officer

David has been active in developing utility-scale solar and wind farms in Australia since 2000 and South Africa since 2010, through his own development companies and during his time as General Manager Development at Infigen Energy. 
Projects include the 64MW Warwick Solar Farm (QLD), 30MW Corowa Solar Farm (NSW), 89.1MW Alinta Wind Farm (WA), 80MW Nojoli Wind Farm (South Africa) and the 96MW Jasper Solar Farm (South Africa).
Of the projects David has developed to date 1GW has been commissioned, and approximately 2 GW are in the advanced stage of development or under

Mac Thompson

Chief Operating Officer

Mac is an experienced technology business founder and CEO. He founded and built DigiGuard, an Australian and New Zealand wide IT business continuity firm, headquartered in Melbourne, and sold it to Iron Mountain (NYSE:IRM). He then founded, built and sold CloudRecover, Australia's largest enterprise private cloud storage and online backup business, to J2Global (NASDAQ:JCOM).

Dr Fraser Thompson

Chief Strategy Officer

Fraser is the founder and CEO of AlphaBeta Singapore, an economic strategy firm, and was the inaugural President of the Australian Chamber of Commerce in ASEAN (“AustCham ASEAN). Fraser is a Rhodes Scholar, with a PhD in Economics from Oxford University and has previously worked for McKinsey & Company and Boston Consulting Group.


The AAPL solar photovoltaic (PV) plant is a 10 gigawatt array situated close to Elliott in the Northern Territory. The site features a world-class solar resource and is located adjacent to existing logistics infrastructure (including the railway, Stuart Highway, and high capacity fibre optic cables), which simplifies construction of the solar farm and storage facility and the high voltage direct current (HVDC) transmission line. The associated 30GWh storage facility will support the solar farm’s operations, enabling 24/7 dispatch of power.

Sun Cable is using rapid deployment prefabricated solar arrays built in our proposed Darwin factory. The arrays will be deployed by rail to the solar site near Elliott. The prefabricated design materially reduces geotechnical risk during construction.


The electricity dispatched from the solar and storage facility will be transmitted to Darwin via an 750 km transmission line. 

Submarine HVDC cables will be installed between Darwin and Singapore. At the load centres, there will be large scale batteries that will enable critical storage.

Community consultation will begin in late 2020
