A massive infrastructure project costing $22 billion will transport clean energy from huge solar farms approximately 3,100 miles (5,000 km) to Singapore. Sun Cable, an Australian company, is leading the project, which intends to start running its high-voltage underwater cable in 2027. It will be the first time the world’s largest solar farm and battery storage facility are combined in one location.

The Sun Cable-sponsored Australia-Asia PowerLink project intends to develop a significant “Powell Creek Solar Precinct” on 12,000 hectares (29650 acres) of dry land around 800 kilometres (500 miles) south of Darwin. The chosen location is one of the sunniest on the planet, and it would house a staggering 17-20 gigawatts of peak solar power generation and 36-42 gigawatt-hours of battery storage.

Overhead cables will carry power north to the coast, then northwest to Singapore through a 4,200-kilometer (2,600-mile) high-voltage DC undersea cable that will execute a dog-leg through some of Indonesia’s most challenging islands. According to Sun Cable, it would deliver up to 3.2 GW of dispatchable clean energy, enough to power up to three million homes and provide up to 15% of Singapore’s electricity.

To get things started, the business completed a Series A capital raise and finished the subsea survey procedure for the 750 km (466 miles) of the route that runs through Australian seas. Indonesia has agreed to participate, having obtained a survey permit and proposed the cable route.
Environmental studies have started, capital raising will end in 2023, and construction will commence shortly thereafter. By the beginning of 2026, power will be sold in Darwin, and Singapore will be operational by 2027.
