In 2024, Australia and Singapore will complete what’s called the “Australia-Asia Powerlink” The project will create a 12,000-hectare solar precinct of arid land about 800km south of Darwin. Australia has an abundance of sunshine, unused and uninhabitable land and a world-class solar industry to build out a national-scale bitcoin mining operation unlike anywhere else. The machines can operate on-site, directly at the plant, no need to build underwater pipes and overground cabling.
According to Newatlas “Power will travel north to the coast through overhead cables, and then it'll travel northwest to Singapore via some 4,200 km of high-voltage DC submarine cable along the sea floor, making a dog-leg through some of the fiddly islands of Indonesia. It'll supply up to 3.2 GW of dispatchable clean energy, which Sun Cable says will provide up to 15 percent of Singapore's electricity and power up to three million homes.
Furthermore, most of the project’s expense is the expansive overground and underwater cabling and pipes.
