AusNet Services is initiating this Regulatory Investment Test for Transmission (RIT-T) to evaluate options for maintaining supply reliability in north-eastern metropolitan Melbourne. Publication of this Project Specification Consultation Report (PSCR) represents the first step in the RIT-T process in accordance with clause 5.16 of the National Electricity Rules (NER) and section 4.2 of the RIT-T Application Guidelines.

As expected of assets that have been in service for a long time, the condition of the transformers, circuit breakers, and instrument transformers at Templestowe Terminal Station has deteriorated to a level where there is a material risk of asset failure, which could have an impact on electricity supply reliability, safety, environment, and potential costs of emergency replacements. 

AusNet Services estimates that the present value of the baseline risk costs associated with maintaining the existing assets in service is $77 million – the biggest component of which comes from the supply interruption risks borne by electricity consumers.

AusNet Services has identified three credible network solutions that could meet the identified need and welcomes proposals from proponents of potential non-network solutions.
Submissions should be emailed to rittconsultations@ausnetservices.com.au on or before 24 March 2020. In the subject field, please reference ‘RIT-T PSCR Templestowe Terminal Station.’
