Powerlink has recently published a Project Assessment Conclusions Report (PACR) to address the secondary systems condition risks at Belmont Substation.
Belmont Substation is located in South East Queensland, approximately eleven kilometres south east of the Brisbane CBD, and forms part of Powerlink’s transmission network supplying electricity to the Energex distribution network in the surrounding local area and south of Brisbane.
Several secondary systems at the Belmont Substation are reaching the end of their technical service life and are facing obsolescence with manufacturer support and spares no longer available.
In September 2018 Powerlink published a Project Specification Consultation Report (PSCR) identifying the proposed preferred option to address the risks and claiming exemption from producing a Project Assessment Draft Report as allowed for under NER Clause 5.16.4(z1). There were no submissions received in response to the PSCR which closed in December 2018. As a result, no additional credible options that could deliver a material market benefit have been identified and the outcomes of the economic analysis contained in the PACR remain unchanged from those published in the PSCR.
The PACR recommends replacing all ageing and obsolete 275kV secondary systems in the free space of the existing building by December 2020. The estimated capital cost is $8.6 million in 2017/18 prices. Powerlink is the proponent of this network project.
In accordance with the requirements of the Rules, a summary of the PACR has been made available on AEMO’s website. A copy of the PACR can be obtained from the Powerlink Website on the RIT-T Consultations page or by emailing firstname.lastname@example.org.
