Project Overview

After almost 50 years in service, the Eyre Peninsula’s existing high-voltage power line is approaching the end of its operational life. To ensure the Eyre Peninsula has a secure and reliable electricity supply for the next 50 years, ElectraNet is building a new high-voltage power line and upgrading five substations.

About the project

Eyre Peninsula Link involves the construction of a new, double-circuit 132 kV transmission line from Cultana to Port Lincoln, via Yadnarie, with the ability to upgrade the Cultana to Yadnarie section to 275 kV at a later date.

Benefits of the new line

The new line will provide homes and businesses throughout the Eyre Peninsula with a secure and reliable power supply. Other benefits of the project include:

  • increasing capacity to connect more users to the electricity network;
  • enabling new renewable energy projects to connect in the future;
  • opportunity to extend the network in future; and
  • during construction, workers spending money in the communities they’re working in.

Project work opportunities

As at late June 2021 nearly 60% of all subcontracts awarded for the EP Link project had been awarded to South Australian businesses with 25% of these awarded to Eyre Peninsula-based businesses.





Line route

The route of the new line runs almost parallel to the existing transmission line, on its western side. The route was identified through engineering, research, technical field studies and direct engagement with landowners and the broader Eyre Peninsula community.

As part of the project, some temporary transmission lines will be constructed which will ensure power supply can be maintained to the Eyre Peninsula while the new line is being built.

Route characteristics

The chosen route achieves the best balance of environmental, cultural, social, land use, engineering and cost criteria. The transmission line route:

  • Reflects community preferences to contain the new and old infrastructure within the same corridor, to the west of the existing line. This was the strongest preference in landowner feedback to ElectraNet.
  • Has the least environmental impact by using existing access tracks to minimise vegetation clearance.
  • Minimises impacts on culturally sensitive sites. Cultural heritage will be managed through a specific Aboriginal Cultural Heritage Management Plan.
  • Achieves the lowest cost for consumers as it is the shortest, most direct route between its fixed connection points.

Current status

Project construction commenced in March 2021 and ElectraNet held a concrete pouring event for local media in May 2021.

ElectraNet and its contractor Downer Group continues to engage with landholders to discuss access to their property during construction and answer questions they may have.

Project timing

Construction on the new transmission line is expected to be completed and the line energised by late 2022. 

Working with landholders and the community

ElectraNet will continue to engage directly with landowners along the project corridor to manage possible issues such as access, timing, vegetation removal and rehabilitation. We will also be in the field collecting environmental and engineering information to ensure the project’s successful delivery.

Removal of old power line

At this stage, most sections of the existing line will remain and be maintained.


EPBC Approval

The Eyre Peninsula Link transmission line was approved under the EPBC Act. The controlling provisions are listed threatened species and communities (section 18 and 18A of the EPBC Act). Management Plans have been prepared to manage impacts on threatened species and communities and are available for download below:

Response to public comment

The Eyre Peninsula Link transmission line is controlled under the EPBC Act. The controlling provisions are listed threatened species and communities (section 18 and 18A of the EPBC Act). Proposed construction activities have the potential to impact on Malleefowl (Leipoa ocellata), Jumping Jack Wattle (Acacia enterocarpa) and Tufted Bush Pea (Pultenaea trichophylla).

In accordance with Section 95A(3) of the EPBC Act, ElectraNet made the preliminary documentation available for public comment from 17 December 2020 to 11 January 2021. No public submissions were received on the Preliminary Documentation during this time.

In accordance with Section 95B(4) of the EPBC Act, written advice noting that no comments were received, the original EPBC referral document and the Preliminary Documentation is available for information for 20 business days from the date of advertisement.
