Powerlink has recently published a ‘Project Specification Consultation Report’ (PSCR) to address the secondary systems condition risks at Mt England Substation.
Mt England Substation is a 275kV switching station located approximately 39km north-west of the Brisbane Central Business District. It was established in 1983 to provide a connection point for Wivenhoe Power Station and facilitate the flow of energy from Tarong Power Station into the greater Brisbane transmission network via feeders to South Pine, Blackwall and Abermain Substations.
Planning studies have confirmed there is a long-term requirement to continue to supply the existing electricity services provided by Mt England Substation.
Commissioned almost 20 years ago, most of the secondary systems at Mt England Substation are reaching the end of their technical service lives, and are no longer supported by the manufacturer, with limited spares available.
The proposed preferred option to meet the identified need that is considered to satisfy the Regulatory Investment Test for Transmission (RIT-T) involves the replacement of selected secondary systems at Mt England, utilising the spare space in the existing building, by October 2023.
The indicative capital cost of the RIT T project for the preferred option is $10.26 million in 2019/20 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 close on 2 March 2020.
