Australia on Wednesday approved plans for a massive solar and battery farm that would export energy to Singapore, a project dubbed the “largest solar precinct in the world”, AFP reported.

Authorities announced environmental approvals for the US$24 billion SunCable project in Australia’s remote north that is slated to power three million homes.

The project will include an array of panels, batteries and, eventually, a cable linking Australia with Singapore.

“It will be the largest solar precinct in the world –- and heralds Australia as the world leader in green energy,” said Environment Minister Tanya Plibersek.

It is hoped that energy production will begin in 2030.

The 12,000-hectare (29,650 acre) project will provide four gigawatts of energy per hour for domestic use. Two more gigawatts sent to Singapore via undersea cable will supply about 15 percent of the city-state’s needs.

Batteries would be able to store about 40 gigawatts.
