Calvale to Calliope River Transmission Line Reinforcement Project

Project overview

Powerlink is planning for a new transmission line between the Calvale Substation (near Callide Power Station) and the Calliope River Substation (near Gladstone). 

The project will strengthen and increase capacity of the transmission network in the region.   

At 87km long, the new double circuit 275kV transmission line will mostly be constructed in existing spare easements, beside existing transmission lines. 

The project also involves grid connections at both substations, as well as expanding the Calliope River Substation to accommodate the new infrastructure and increased energy needs.
