Design and construction

Designing the Western Renewables Link

Designing an overhead transmission line is a complex and evolving process. We consider community, environmental and economic impacts, operational and maintenance requirements, as well as technical, construction and safety standards and regulatory requirements.

Design process

Our engineers began by producing a preliminary route design based on:

  • the functional requirements of the transmission line provided by the Australian Market Energy Operator
  • community and stakeholder feedback combined with the findings of technical studies, field surveys and investigations
  • understanding the existing conditions along the proposed route, while reducing impacts to agriculture and other land uses, residential areas, native flora and fauna, Aboriginal cultural heritage, landscapes and many other important factors.

We implemented over 100 design iterations from landholder and community feedback, technical specialist reviews and findings from surveys and investigations.

These changes are part of developing the proposed design in the Environment Effects Statement (EES). Further design changes may be required following the EES assessment and approvals processes.

Once all approvals are received, we’ll provide the design to our approved construction contractor.

Constructing the Western Renewables Link

AusNet has chosen an Early Contractor Involvement (ECI) procurement process to select a delivery partner, which is a method of construction contracting where the contractor is engaged in an early phase of the project to provide input into the design and construction process.  

Before construction starts, we will meet with landholders to discuss and plan the construction activities to ensure any site or property-specific requirements are considered, such as the need for fencing or the removal of livestock.

We will also inspect the site to assess the general area and ground conditions and complete any final site investigations for engineering and environmental requirements.

After construction

Once construction is complete, we’ll carry out inspections and safety tests before the transmission line goes live.

All construction areas and access tracks that are not needed for the ongoing operation of the Western Renewables Link will be reinstated and rehabilitated, including revegetation - unless the landholder requests that the access track remains. We will remove temporary infrastructure and waste and work with landholders to return the site close to its original appearance.
