4,300 km long cable to transmit clean electricity across the sea

The Northern Territory Government has recently approved the Australia - Asia Power Link, the world's largest renewable energy transmission project.

The Australia-Asia Power Link, led by Australian company SunCable, will bring solar power from Australia to Singapore via a 4,300km cable. Singapore is cramped and looking to transition to renewable energy, while Australia's Northern Territory has vast, sunny spaces. The new project will connect the two locations.

The Northern Territory Government has also granted environmental approval for the construction of a large-scale solar farm at Powell Creek with a clean energy generation capacity of up to 10 GW. This also paves the way for the construction of an 800 km overhead transmission line between the solar farm and Murrumujuk near Darwin.

One facility will convert high-voltage direct current to high-voltage alternating current to provide around 4 GW of green electricity 24/7 to industrial customers in Darwin. The project also aims to transmit 1.75 GW of electricity to Singapore via 4,300 km of submarine cables.

Before the Australia-Asia Power Link project can actually be implemented, SunCable still has a number of major hurdles to overcome including negotiating land use with landowners, dealing with other regulatory bodies along the cable route and finding funding.

If all goes well, clean electricity transmission is expected to begin in the early 2030s. The ultimate goal of the project is to produce up to 20 GW of solar power and store it in a 36-42 GWh on-site battery system.
