Powerlink has recently published a ‘Project Specification Consultation Report’ (PSCR) to maintain reliability of supply to the Brisbane Metropolitan area.

The West Darra to Rocklea and South Pine to Upper Kedron transmission lines are 110kV double circuit lines that form part of the Greater Brisbane transmission network in the Moreton transmission zone, with the South Pine and Rocklea Substations providing the high voltage injection points for the western part of the Greater Brisbane area.

Originally commissioned in 1963 the lines are nearing the end of their technical service lives, with the majority of structures exhibiting signs of advanced corrosion, presenting an increased risk of mechanical failure, particularly in storm and severe wind conditions. The earth wires are also not sufficiently rated to cater for the continuing growth in forecast fault levels over time.

The proposed preferred option that is considered to satisfy the Regulatory Investment Test for Transmission (RIT-T) involves a two stage refit of selected lines in 2020 and 2028, followed by a rebuild of the lines in 2043.
 
The estimated capital cost of the work to be carried out by December 2020 under this RIT-T is $4.55 million in 2018/19 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 19 February 2019.
