The Australian Energy Regulator (AER) has received a request from ElectraNet to make a determination that the preferred option identified through its Eyre Peninsula Electricity Supply Options Regulatory Investment Test for Transmission (RIT-T) satisfies the requirements of the RIT-T.
ElectraNet's Eyre Peninsula Electricity Supply Options RIT-T has explored options for providing a reliable supply to the Eyre Peninsula most efficiently into the future. ElectraNet released its final RIT-T report 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. We will assess ElectraNet's application of the RIT-T and make a determination as to whether the preferred option identified by ElectraNet satisfies the RIT-T, in accordance with the requirements of the National Electricity Rules.
