Powerlink has recently published a 'Project Assessment Conclusions Report' to address the reliability of supply risks 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 first step of the Regulatory Investment Test for Transmission (RIT-T) was the publication of the Project Specification Consultation Report (PSCR) in October 2018 which invited submissions particularly on the credible options which could address the identified need.
The proposed preferred option identified in the PSCR considered to satisfy the RIT-T involved the staged replacement of selected primary plant, with the first stage scheduled for completion by December 2022. There were no submissions received in response to the PSCR which closed on 25 January 2019.
The outcomes of the economic analysis contained in the PACR remain unchanged from those published in the PSCR. Consequently, the draft recommendation to replace selected primary plant by December 2022 has been adopted without change as the final recommendation in the PACR.
The estimated capital cost is $4.94 million in 2018/19 prices. Powerlink is the proponent of this project.
In the context of engagement activities with consumers and the general community, Powerlink has assessed this project as ‘minor’ on the RIT-T Stakeholder Engagement Matrix.
