Project Specification Consultation Report – Summary

Regulatory Investment Test – Transmission – June 2022

AusNet Services is undertaking this Regulatory Investment Test for Transmission (RIT-T) to evaluate options to apply corrective actions to maintain reliable transmission network services along multiple Extra-High Voltage (EHV) circuits.

Publication of this Project Specification Consultation Report (PSCR) 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.

AusNet Services determined that the present value of the baseline risk cost associated with keeping the assets in service is more than $114 million. AusNet Services is therefore investigating options that could allow continued delivery of safe and reliable transmission network services along multiple Extra-High Voltage (EHV) lines.

AusNet Services welcomes written submissions on the issues and the credible options presented in this PSCR.  Submissions should be emailed to on or before 13 September 2022.  In the subject field, please reference ‘RIT-T PSCR Transmission Line Insulator Replacement.'
