AusNet Services undertook this Regulatory Investment Test for Transmission (RIT-T) to evaluate options to maintain reliable transmission network services at Horsham Terminal Station (HOTS).

The Project Specification Consultation Report (PSCR), which represents the first step in the RIT-T process was published in June 2020 and the succeeding Project Assessment Draft Report (PADR) was published in April 2021. Publication of this Project Assessment Conclusions Report (PACR) represents the third and final 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.

The non-network proposal for this RIT-T have been made in confidence and AusNet Services is thus not allowed to publish any part of the non-network proposal. Instead a notional non-network option is modelled to assess the economic merits of a non-network option.
AusNet Services concludes that replacement with a modern SVC or FACTS such as a STATCOM is the most economic option to address the identified need as it provides the highest present value of net economic benefits for all scenarios and sensitivities investigated with an optimal timing of 2025/26.
