Project Assessment Draft Report – Summary
Regulatory Investment Test – Transmission – February 2025
AusNet Services is undertaking this Regulatory Investment Test for Transmission (RIT-T) to evaluate options to maintain reliable 330/220 kV transformation network services at South Morang Terminal Station (SMTS).
The Project Specification Consultation Report (PSCR), which 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 was published in August 2024. This report, the Project Assessment Draft Report (PADR), is the second stage of the RIT-T and provides information about the draft conclusions of the RIT-T.
No non-network proposals were received during the RIT-T PSCR consultation.
The preferred option to address the asset failure risk at SMTS is replacement of the H1 and H2 transformers with an in-service and a hot spare transformer by 2029.
AusNet Services welcomes written submissions on the issues and the credible options presented in this PADR. Submissions should be emailed to rittconsultations@ausnetservices.com.au on or before 11 April 2025.
