AusNet Services undertook this Regulatory Investment Test for Transmission (RIT-T) to evaluate options to maintain reliable transmission network services at Keilor Terminal Station (KTS).
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 July 2024 and the Project Assessment Draft Report (PADR) in May 2025. This report, the Project Assessment Conclusions Report (PACR), is the last stage of the RIT-T and provides information about the conclusions of the RIT-T.
No non-network proposals were received during the RIT-T consultation.
The preferred option to address the asset failure risk at KTS is replacement with standard 1000 MVA 500/220 kV transformers by 2031 as it provides the highest present value of net economic benefits for all scenarios and sensitivity studies.
