The Australian Energy Regulator (AER) has approved funding for Electranet's proposed new high-voltage transmission line for Eyre Peninsula.
ElectraNet is proposing to build 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 when needed.
Major work on the 'Eyre Peninsula Link' includes upgrading substations at Port Lincoln, Cultana, Yadnarie, Wudinna and Middleback, plus a new 270-kilometre transmission line.
The proposal's funding application was submitted earlier this year, with AER's approval the final regulatory approval required.
Electranet chief executive officer Steve Masters said the approval was another important milestone for the project, which would improve power security and reliability in the region, plus provide a boost to the local economy through construction jobs and the use of local suppliers.
He said construction work was planned to begin in March 2021.
"Building a new, 270km high-voltage transmission line and upgrading five of our electricity substations is expected to take about 18 months to complete, with the new power line planned to be energised in December 2022," he said.
"Improving power delivery to the Eyre Peninsula is part of ElectraNet's commitment to provide reliable and affordable electricity transmission services to meet the state's current and future needs."
ElectraNet and early works contractor Downer Infrastructure Projects hosted two local industry briefings in August, outlining how interested businesses could get involved in the project.
More than 100 local and state-based businesses attended the online briefings, following which interested businesses could register their details for a project database to be provided to the successful project contractor.
The project will require more than 200 workers during peak construction.
ElectraNet said the project would meet the immediate power supply needs of Eyre Peninsula communities, while future-proofing the network to cater for increased capacity for mining developments and renewable energy projects in the region.
