Draft Project Assesment Report – Summary
Regulatory Investment Test – Distribution – October 2024
AusNet initiated this Regulatory Investment Test for Distribution (RIT-D) to investigate and evaluate options to address the constraints in the MWTS South sub-transmission network which are restricting new renewable generation connections.
The Options Screening Report (OSR), which represents the first step in the RIT-D process in accordance with clause 5.17 of the National
Electricity Rules (NER) and section 4.2 of the RIT-D Application Guidelines was published in January 2024. This report, the Draft Project Assessment Report (DPAR), is the second stage of the RIT-D process and provides information about the draft conclusions of the RIT-D.
Two non-network proposals were received during the RIT-D OSR consultation phase.
The preferred solution is to augment the MWTS – LGA No.2 and No.3 66kV lines with 37/3.75 conductor to increase the overall summer rating of MWTS – LGA to 236 MVA. The estimated capital cost of the preferred option is $106.1 million (nominal).
AusNet welcomes written submissions on the the credible options evaluation and draft conclusion presented in this DPAR. Submissions should be emailed to ritdconsultations@ausnetservices.com.au on or before Wednesday 27 November 2024. In the subject field, please reference ‘RIT-D DPAR CE Morwell South’
