Harnessing the Northern Territory’s world-class solar resource
The opportunity
Global demand for electricity is accelerating — driven by electrification, digital infrastructure, and the transition to lower‑carbon energy systems.
Meeting this demand is not just about generating more power. It requires new approaches to delivering energy at scale, reliably, and in locations where it can unlock long-term economic activity.
Northern Australia’s exceptional solar resource presents a rare opportunity to do exactly that.

Our vision
SunCable is developing a large-scale energy precinct in the Barkly Region of the Northern Territory, designed to deliver low-cost, firmed renewable electricity for industrial customers in Northern Australia and Southeast Asia.
The project integrates solar generation, battery storage, and high-voltage direct current (HVDC) transmission to enable multi-gigawatt, off-grid power.
This supply could support the decarbonisation of existing industries, while enabling new opportunities for investment and energy export.
The project will be developed in stages to align with customer demand, across three locations:
- At-site in the Barkly region from the late 2020s
- New and existing industries in Darwin from the early 2030s
- Singapore and Southeast Asia via cross-border electricity trade (CBET) from the mid-2030

A globally differentiated location
The Barkly region offers a unique combination of natural advantages and enabling infrastructure that is difficult to replicate.
A unique opportunity for data centre development
The project presents an opportunity for customers to co-locate with SunCable’s generation precinct, with access to gigawatt-scale renewable electricity and the land, infrastructure and connectivity required for hyperscale data centre development.

SunCable has made significant progress and is at an advanced stage of development.
Key milestones to date include:
- 2020 - Pastoral Land Use Agreement secured for the generation site and an Option Agreement signed with the Australasian Railway Corridor (AARC) for the overhead transmission line
- 2021 - Host Government Agreements and facilitation frameworks established with the Northern Territory and Australian governments
- 2022 - Project legislation passed by the Northern Territory Government
- 2022 - Benefits package agreed with the Indonesian Government
- 2024 - Major environmental approvals granted by the Australian and Northern Territory governments
- 2024 - Conditional approval granted by the Energy Market Authority of Singapore to import 1.75GW of renewable electricity into Singapore from 2035
- 2025 - Indonesian development approvals and permits secured for the subsea transmission system
- 2025 - Cross Border Electricity Trade (CBET) framework agreed between the Singapore and Australian Prime Ministers
- 2025 - 70-year Indigenous Land Use Agreement (ILUA) signed with the Traditional Owners of Powell Creek
SunCable has made significant progress towards delivering one of the world’s largest renewable energy projects, supporting economic growth in Northern Australia and decarbonisation of South-East Asia.
