Sun Cable Project Expands with 12GW Wind Addition
New details have emerged regarding the future of Sun Cable, the world’s largest renewable energy and storage initiative, with plans to incorporate 12 gigawatts (GW) of wind power alongside extensive solar arrays and large-scale battery systems in the Northern Territory.
These revelations were disclosed by Quinbrook Infrastructure Partners, the global investor enlisted by Sun Cable’s primary supporter, software tycoon Mike Cannon-Brookes, to explore local opportunities for the project.
Enhanced Project Scope
Following comprehensive studies spanning almost a year, Quinbrook recognised the potential benefits of integrating wind energy into the project, which initially focused on 20 GW of solar capacity and 42 GWh of battery storage.
After careful evaluation, Quinbrook has refined the project’s configuration, proposing 12 GW of wind power, a reduction from the original 20 GW solar capacity, and a decrease in storage to 32 GWh. This adjustment acknowledges the crucial role wind energy will play in sustaining power generation post-sunset.
Project Phases and Expansion
James Allan, a director at Quinbrook and Sun Cable, indicated that the project is likely to be implemented in two phases. The initial phase will encompass 12 GW of wind and solar capacity, along with 16 GWh of battery storage.
Notably, this phase will target connections to Singapore and the facilitation of a new eco-friendly manufacturing hub at Middle Arm in Darwin, expanding beyond the previously envisioned domestic focus.
The subsequent phase will involve an additional 12 GW of wind and solar power, alongside 16 GWh of battery storage, with a primary focus on enhancing the Singapore connection.
Project Scale and Impact
Allan highlighted the ambitious nature of the project, labelling it as one of the world’s most extensive behind-the-meter initiatives. The project involves establishing a dedicated cable network to the Middle Arm precinct, independent of the existing Darwin grid.
By channelling six gigawatts into Darwin and allocating four gigawatts to support green industries at Middle Arm, the project aims to contribute significantly to sustainable energy practices.
Moreover, a substantial portion of the generated power will be directed towards the international cable, ultimately reaching Singapore to aid in the country’s decarbonisation efforts.
Future Prospects and Collaborations
Allan emphasised the project’s potential to foster the growth of new industries in Darwin, aligning with the overarching goal of establishing a thriving green economy in the region.
Additionally, Quinbrook’s involvement in other renewable energy ventures, such as the $8 billion polysilicon production project, underscores the company’s commitment to advancing Australia’s position in the global solar supply chain.
As the project progresses, Sun Cable aims to support various initiatives and contribute towards Darwin’s objective of creating a $40 billion green economy.
With abundant resources and strategic advantages, Australia is poised to capitalise on emerging markets and solidify its position in the renewable energy landscape, driving towards a sustainable future.
