Powerlink has recently published a ‘Project Specification Consultation Report’ (PSCR) to address the secondary systems condition risks at Mudgeeraba.

Located approximately 10km north of the Queensland-NSW border, Mudgeeraba Substation was established in 1970 as a 110kV switchyard. It was expanded in the late 1990s with the addition of a 275kV switchyard and now serves as the major injection point for the distribution networks supplying the southern Gold Coast in Queensland and north-eastern New South Wales, supporting a diverse range of customer needs in these areas.

Planning studies have confirmed there is an enduring need to continue to supply the existing electricity services provided by Mudgeeraba substation. Commissioned approximately 20 years ago, the Mudgeeraba secondary systems are reaching the end of their technical service lives, and are increasingly no longer supported by their manufacturer, with limited spares available.

The proposed preferred option that is considered to satisfy the Regulatory Investment Test for Transmission (RIT-T) involves the replacement of the 275kV secondary systems in a new building at Mudgeeraba, by December 2021.

The indicative capital cost of the RIT‑T project for the preferred option is $8.3 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 27 September 2019.
