What Suncable does

SunCable is a privately held Australian renewable energy infrastructure developer founded in 2018 and headquartered in Sydney, with offices across Darwin, Brisbane, Melbourne, Singapore, and Jakarta. The company is developing the Australia-Asia PowerLink (AAPowerLink), a single integrated giga-scale project that combines a 17-20 GWp solar generation precinct and 36-42 GWh battery energy storage system in the Barkly region of the Northern Territory, an approximately 800 km overhead HVDC transmission line to Darwin, and a 4,200 km subsea HVDC cable from Darwin through Indonesian waters to Singapore. The AAPowerLink and the related 20 GW Muckaty Solar Precinct extension (submitted for federal environmental assessment in November 2025) are designed to deliver firm, 24/7 dispatchable renewable electricity rather than intermittent power.

The technology integrates three proven components — utility-scale solar PV, co-located battery storage, and HVDC transmission (both overhead and subsea) — at a scale the company describes as world's-largest in each category. Delivery is executed through an Integrated Project Delivery Team (IPDT) consortium comprising Bechtel, SMEC, Surbana Jurong, Hatch, Marsh, and PwC Australia. As of 2024-2025, SunCable has stacked principal regulatory approvals from the NT Environment Protection Authority (July 2024), the Commonwealth EPBC process (August 2024), Singapore's Energy Market Authority (Conditional Approval, October 2024, to import 1.75 GW from 2035), the Indonesian government for subsea corridor permits (2025), and Major Project Status with both Australian and NT governments. The company has also signed a 70-year Indigenous Land Use Agreement with Powell Creek Traditional Owners (2025) and a bilateral Cross-Border Electricity Trade (CBET) framework between the Australian and Singapore Prime Ministers (2025).

The business model is built around long-term, subscription-style offtake contracts with two anchor customer groups: (i) Singapore's Energy Market Authority and Singapore power grid, which will receive up to 1.75 GW (about 15% of national demand) from 2035, and (ii) green industrial customers in Darwin (green hydrogen, e-fuels, data centres, green minerals), which will receive up to 4 GW staged from the late 2020s (900 MW Stage 1, ~3 GW Stage 2). Pricing for these contracts is not publicly disclosed. SunCable has invested over AUD $250 million cumulatively across Australia, Singapore, and Indonesia, and projects AUD $20 billion-plus in economic value to the Northern Territory over construction and 35 years of operation. The company is pre-revenue today, with Final Investment Decision targeted for 2027.

Core offering

SunCable develops large-scale renewable energy infrastructure integrating solar photovoltaic generation, utility-scale battery storage, and High Voltage Direct Current (HVDC) transmission to deliver firm 24/7 dispatchable green electricity. Its flagship Australia-Asia PowerLink (AAPowerLink) project combines the world's largest solar precinct (17-20 GW), the world's largest battery energy storage system (36-42 GWh), and the world's longest subsea cable (4,200km) to supply green electricity to industrial customers in Darwin and export up to 1.75GW to Singapore.

Product overview

SunCable is developing a single unified renewable energy project—the Australia-Asia PowerLink (AAPowerLink)—which integrates multiple complementary components: the Muckaty Solar Precinct for solar generation, co-located battery energy storage, and the HVDC Transmission System for long-distance power delivery. The AAPowerLink will deliver up to 4GW of green electricity to Darwin via overhead transmission, and 1.75GW to Singapore via the world's longest subsea cable (4,200km), with generation sourced from Northern Australia's world-class solar resources. The company also supports Cross-Border Electricity Trade (CBET) frameworks that enable international renewable energy commerce between Australia and Southeast Asia.
