On 4 December 2019 ElectraNet published a Project Assessment Conclusions Report (PACR) that confirms the preferred option is to replace the identified end-of-life protection relays to manage the risk of protection relay failure.

ElectraNet has published a Project Specification Consultation Report (PSCR) for Managing the Risk of Protection Relay Failure under the Regulatory Investment Test for Transmission (RIT-T), which is the first step in the RIT-T process, as required by the National Electricity Rules clause 5.16.
The PSCR identifies the targeted replacement of around 380 protection relays and components across the South Australian electricity transmission network over the next four years as the most efficient solution to manage the overall fleet of protection relays across the network.
The protection relays that are being replaced are located in the following substations:
- Metropolitan substations – Angas Creek, East Terrace, Happy Valley, Kilburn, Morphett Vale East, Mount Baker, Northfield, Parafield Gardens West, Templers; and
- Rural Substations – Berri, Brinkworth, Davenport, Hummocks, Kincraig, North West Bend, Pimba, Port Lincoln, Robertstown, Snuggery, South East, Stony Point, Tailem Bend, Yadnarie
The report identifies that there is only one technically and economically feasible option which is to replace the identified protection relays on the network.
The PSCR is available for download at ElectraNet.
