Draft Project Assesment Report – Summary

Regulatory Investment Test – Distribution – July 2024

AusNet initiated this Regulatory Investment Test for Distribution (RIT-D) to investigate and evaluate options to address the constraints in the MWTS East 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 2014. 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.

No non-network proposals were received during the RIT-D OSR consultation phase.
The preferred solution is to augment the MWTS – TGN No.1 and No.2 66kV lines with 19/4.75 conductor to increase the overall summer rating of MWTS – TGN to 202 MVA. The estimated capital cost of the preferred option is $4.8 million (nominal).

AusNet welcomes written submissions on the issues and the credible options presented in this DPAR. Submissions should be emailed to on or before Wednesday 21 August 2024.  In the subject field, please reference ‘RIT-D DPAR CE Morwell East.’
