Powerlink has recently published a ‘Project Specification Consultation Report’ (PSCR) to maintain reliability of supply at the Townsville South Substation.

Located approximately 11 kilometres south east of the Townsville CBD, Townsville South Substation is a major injection point into the Ergon Energy distribution network for southern and eastern Townsville, as well as a transfer point for enabling the flow of electricity between Clare to the south and Townsville to the north. Planning studies have confirmed there is an enduring need to maintain the supply of electricity in the Townsville area.

At over 40 years of age, much of the substation’s primary plant is reaching the end of its technical service life and is no longer supported by the manufacturer, with few spares available.

The proposed preferred option that is considered to satisfy the Regulatory Investment Test for Transmission (RIT-T) involves the three staged replacement of selected equipment in existing bays, utilising live tank circuit breakers, in 2022, 2030 and 2045.
The estimated capital cost of the work to be carried out by December 2022 under the RIT-T is $4.94 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

Submissions on the PSCR are required by the closing date of 25 January 2019.
