To support the energy transformation and development of Queensland’s clean energy economy, Powerlink is required to reinforce our transmission network in the Gladstone area in coming years.


In preparation for the transition of the electricity system to renewable supply, we are looking to reinforce the transmission network between Calvale to Calliope River by building an additional double circuit 275kV transmission line, expected to extend around 87km long. 

Powerlink aims to co-locate the new transmission line adjacent to the existing line, and where possible, within existing easements. Some widening of existing easements is required to determine a new alignment for a 16km stretch and new easements required to formalise Powerlink’s existing rights over State Forest, a timber reserve and Conservation Park.


Powerlink has started early engagement with landholders, community members and other stakeholders to gather information and feedback locally to finalise the location of the additional 275kV transmission line. Our early discussions are focused on seeking input and insights to help guide our planning.

Get involved

We are committed to ongoing genuine and timely engagement with landholders, local communities and other stakeholders to support the reinforcement of our transmission network in the Gladstone region.

Your input is important to help us understand landholder and community views, and areas of interest and importance. We will also be hosting community information drop-in sessions in late 2023 where you can meet our team, ask questions, share feedback and provide local input.

In the meantime, please contact us by phone or email. Alternatively you can leave your comments on the interactive project map available here.

Draft Renewable Energy Roadmap

In July 2023, the Queensland Government released a draft Renewable Energy Zone (REZ) Roadmap. The draft Roadmap will help improve long-term regional planning and coordination for renewable energy.

The Roadmap outlines the proposed process for declaring and developing REZs in Queensland. Powerlink will serve as the REZ Delivery Body, responsible for coordinating how and when a renewable energy project connects to the network in a REZ. This will help deliver the right mix of energy technologies, in the right location.

For further information regarding the REZ Roadmap please visit the Department of Energy and Public Works.
