AAPOWERLINK PROJECT

Founded in 2018, Sun Cable is an Australian, world-leading renewable energy company. Their mission is to develop systems to supply renewable electricity from resource abundant regions to growing load centres, at scale to power the Indo-Pacific region with competitively priced, dispatchable, high volume renewable electricity. The AAPowerLink project is the first of its kind and the first of many.

Rapid advancements in renewable energy and battery technology, combined with the evolutionary changes in HVDC cable systems (reducing cost and increasing efficiency and reliability) have made it economical to transport energy over long distances.

Sun Cable’s energy projects will position Australia, Singapore and other markets in Asia as world leaders in intercontinental transmission of renewable electricity. This infrastructure will facilitate the electrification of new and existing industries, supporting large-scale economic development, whilst reducing greenhouse gas emissions.

We are an international company with employees working across the region. We have offices in Singapore, Jakarta, Sydney, Darwin, Canberra and Brisbane.

Overview of the project

Sun Cable is developing the Australia-Asia PowerLink (AAPowerLink), a high-capacity solar generation, storage and transmission system that will transmit large volumes of renewable electricity from the Barkly Region of the Northern Territory to Darwin and Singapore markets. The AAPowerLink will provide Darwin and Singapore with high quality, dispatchable renewable electricity supply.

A world-leading team of highly skilled experts from SMEC (Surbana Jurong Group), Bechtel, Hatch, Marsh, and PwC Australia have assembled to deliver this multi gigawatt scale project.

Construction is expected to take four to five years and is proposed to start around early 2024. Supply of power to the Northern Territory is planned to commence in 2026, with supply to Singapore to commence in 2027 with the system fully operational by the end of 2028.

The AAPowerLink project comprises a number of key components:

• Solar farm precinct including energy storage and voltage source converter (VSC) at Powell Creek near Elliott in the Northern Territory;

• High voltage direct current (HVDC) overhead transmission line (OHTL) from the solar farm to Darwin;

• VSC and a utility-scale battery in Darwin;

• Cable Transition Facilities to enable transition of power cables between land and sea in Darwin and Singapore

• Subsea HVDC cable system from Darwin to Singapore; and VSC and utility-scale battery in Singapore.

Key Project Statistics

• Solar precinct covering 12,000 hectare that generates 17-20 GWp from the solar PV arrays with a 36-42 GWh of energy storage to enable 24/7 dispatchable electricity, at Powell Creek near Elliot in the Barkly Region of the Northern Territory, Australia.

• Approximately 800 km of scalable 3.2-6.4 GW Overhead Transmission Line (OHTL) from the Powell Creek Solar Precinct to Murrumujuk, approx close to 35 km north-east of Darwin.

• Darwin Converter Site including Voltage Source Converters (VSC), energy storage and network connection to supply up to 800 MW of renewable electricity to the Darwin region. • Cable Transition Facilities to enable transition of power cables between land and sea.

• Subsea cable system extending approximately 4,200 km from the Darwin Converter Site to Singapore with approximately 2.2 GW of capacity leaving Darwin.

• Singapore Converter Station including a VSC, grid interconnection and energy storage to supply the Singapore grid.
