Powerlink has recently published a ‘Project Specification Consultation Report’ (PSCR) to address the secondary systems condition risks at Tarong Substation.
Located approximately 130km north-west of Brisbane, Tarong Substation is a major part of the 275kV transmission backbone connecting generators to the major load centres in the south-east of the State. It also provides the major injection point for local, rural and bulk mining loads in south-west Queensland. Several 275kV secondary systems at the Tarong Substation are reaching the end of their technical service life and are no longer supported by the manufacturer, with no spares available.
The proposed preferred option that is considered to satisfy the Regulatory Investment Test for Transmission (RIT-T) involves replacing selected secondary systems in the free space of the existing building by December 2022.
The estimated capital cost of the proposed preferred option is $7.8 million in 2017/18 prices.
In accordance with the requirements of the Rules, a summary of the PSCR is made available on the AEMO website. A copy of the ‘Project Specification Consultation Report’ can be obtained from the Powerlink website on the RIT-T Consultations page or by emailing networkassessments@powerlink.com.au.
Submissions on the PSCR are required by the closing date of 30 November 2018.
