ElectraNet is ready to build a new transmission line on the Eyre Peninsula following final approval from the federal regulator at its final determination on April 11.
The Australian Energy Regulator has approved a new double-circuit 132 kilovolt transmission line from Cultana to Port Lincoln, via Yadnarie with the ability to upgrade the Cultana to Yadnarie section to 275 kilovolts at a later date.
The project, estimated at about $240 million is still subject to other approvals but works are planned to begin in 2020.
ElectraNet chief executive Steve Masters said the news of the approval was great for the Eyre Peninsula with a new transmission line to provide the region with a more reliable and secure electricity supply into the future.
"This new line will meet the immediate supply needs of the Eyre Peninsula and will future proof the network to cater for increased capacity if and when new mining developments and renewable energy projects proceed," he said.
"The regulator's approval of the new power line is great news for all involved and I thank everyone for their input during the project's development and regulatory approval process."
Mr Masters said the cost of the new transmission line would be fully offset by avoiding the cost of replacement works on the existing transmission line and annual generator network support payments.
