On 23 November 2018, ElectraNet submitted an application to the AER seeking a determination that the preferred option identified in the Project Assessment Conclusions Report (PACR) for the Eyre Peninsula Electricity Supply Options RIT-T satisfies the requirements of the RIT-T. 

ElectraNet's Eyre Peninsula Electricity Supply Options RIT-T explored options for providing a reliable supply to the Eyre Peninsula most efficiently into the future. ElectraNet released its Project Assessment Conclusions Report (the final step in the RIT-T process) on 18 October 2018, which identified the following preferred option: 

• a new double-circuit line from Cultana to Yadnarie, initially energised at 132 kV but with the option to be energised at 275 kV if required in the future; and
• a new 132 kV double-circuit line from Yadnarie to Port Lincoln.

The purpose of the RIT-T is to identify the credible option that maximises the present value of net economic benefit to all those who produce, consume and transport electricity in the market.
