The world’s largest project to date for the use and transmission of renewable energies can be put into practice: the city state of Singapore will in future be supplied with solar power from the distant desert regions of Australia.
The so-called Australia-Asia Power Link (AAPowerLink) will in future transport Australian solar power to Singapore via 4,300 kilometers of submarine cables. The project, led by SunCable, begins with the construction of a gigantic solar farm in the Northern Territory in Australia. This plant will not only provide electricity for the city of Darwin, but also export “reliable and low-cost renewable energy” to Singapore.
Some time ago, the government of Australia’s Northern Territory granted environmental approval for the construction of the solar farm in Powell Creek. The Singapore authorities have now also given their approval to the project. This means that practical implementation can now begin. A 4,600 km cable brings PV power from Australia to Singapore
As part of this, photovoltaic capacities with an output of up to 10 gigawatts are to be installed in Australia. There are also large-scale battery storage facilities on site. A substation will convert the electricity generated from high-voltage direct current to high-voltage alternating current to supply Darwin with green electricity.
A capacity of 900 megawatts will initially be delivered in two phases before the capacity is increased to 3 gigawatts in order to provide a total of up to 4 gigawatts of green electricity for industrial customers.
However, 1.75 gigawatts of electricity is fed into the thousands of kilometers long direct current route to Singapore. If everything goes according to plan, the first electricity is expected to be delivered in the early 2030s. In the long term, the Powell Creek solar power plant is expected to generate up to 20 gigawatts of peak power and provide 36 to 42 gigawatt hours of on-site battery storage capacity.
AAPowerLink is one of the most ambitious infrastructure projects that SunCable wants to implement – but not the only one. Together with numerous other partners and research institutions, we are working on the idea of a huge interconnected network for the entire region between Japan, China, India and Australia, which is intended to ensure that fluctuations in renewable energy production can be balanced out over a large area.
