AusNet Services is undertaking this Regulatory Investment Test for Transmission (RIT-T) to evaluate options for maintaining supply reliability in south-eastern metropolitan Melbourne.
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 December 2019. The Project Assessment Draft Report (PADR) was published in August 2020. Publication of this Project Assessment Conclusions Report (PACR) represents the third and final step in the RIT-T process.
No non-network proposals were received during the RIT-T PSCR consultation phase. There has also not been any submission since the publication of PADR.
AusNet Services concludes that replacement of the two 220/66 kV transformers, selected 66 kV circuit breakers and associated primary and secondary assets in a single integrated project by 2024/25 is the most economical solution.
