New transmission line: Queensland Government to build $3.9bn power transmission project

In March, the Government of Queensland, Australia, announced that it would own and build the CopperString 2.0 power transmission line project.

The 1,100km transmission line will connect wind and solar assets with critical mineral mining and processing facilities that are intended to make batteries and renewables in North Queensland. It will have 6GW of clean energy capacity and require a A$5bn ($3.29bn) investment to develop.

CopperString 2.0 is planned to link Mount Isa, Cloncurry and the North West Minerals Province to the National Electricity Grid near Townsville, unlocking Australia’s largest renewable energy zone.
