Transmission line foundations

Summary and scope

Powerlink is delivering a portfolio of electricity transmission projects across Central Queensland to ensure the security of energy supply and the stability of the grid. This is a critical step in reinforcing the network, enabling the transition of power assets such as Gladstone Power Station with new energy sources while maintaining system strength and reliability. These projects are at varying stages of planning, assessment and delivery and will be implemented progressively, subject to regulatory approvals, investment decisions and funding processes. Powerlink is using a coordinated, program level approach across its Central Queensland projects to maximise opportunities for local and Indigenous businesses, while ensuring safe, efficient and reliable delivery of critical transmission infrastructure. Calvale to Calliope River Transmission Line Reinforcement Project Powerlink is constructing a new 87km double circuit 275kV transmission line in Central Queensland, connecting the Calvale Substation ( near Callide Power Station, in the Banana Shire region) to the Calliope River Substation (near Gladstone, in the Gladstone Region). The project will strengthen and increase the capacity of the transmission network across this corridor, supporting reliability and future energy demand in Central Queensland.
