AusNet Services is undertaking this Regulatory Investment Test for Transmission (RIT-T) to evaluate options for maintaining supply reliability in the Brooklyn area. Options investigated in this RIT-T are intended to mitigate the risk of an asset failure at Brooklyn Terminal Station (BLTS).
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 is also exploring opportunities to accelerate the RIT-T process for this project as allowed by NER clause 5.16.4(z1).
AusNet Services estimates that the present value of the baseline risk costs associated with maintaining the existing assets in service is around $20 million – the biggest component of which comes from the supply interruption risks borne by electricity consumers. AusNet Services is therefore investigating options that could allow continued delivery of safe and reliable electricity supply to the customers supplied by the Brooklyn Terminal Station.
AusNet Services identified two credible network options to address the identified need. The preferred solution is replacement of selected 66 kV circuit breakers and switchgear that are in poor condition as soon as possible.
AusNet Services welcomes written submissions on the issues and the credible options presented in this PSCR. Submissions should be emailed to rittconsultations@ausnetservices.com.au on or before 15 February 2021. In the subject field, please reference ‘RIT-T PSCR Brooklyn Terminal Station.’
