The Calvale to Calliope River Transmission Line Reinforcement Project is nearing the end of its planning phase.

State and federal government approval decisions are expected by mid‑2026.

Subject to approval, early construction works are expected to commence shortly after.

We are close to finalising the appointment of principal contractors for the initial clearing and access works and the main construction works. ‘Clearing and access’ refers to the activities required to enable construction of the transmission line.

This involves targeted earthworks and vegetation clearing to prepare the easement for construction.

Expressions of interest for this work were sought via a Vendor Panel in August 2025.

For the main construction works, contractors were short-listed from Powerlink’s experienced supplier panel.

The main works contractor will be responsible for procuring most goods and services needed to build the new transmission line and substation upgrades.

We will announce our successful contractors once the process is complete. Powerlink and our contractors are jointly committed to strong outcomes for local and Indigenous suppliers to support our construction activities wherever possible.
