Powerlink has recently published a Project Assessment Conclusions Report (PACR) to address the secondary system condition risks at Palmwoods Substation.
Located in the Sunshine Coast hinterland, Palmwoods substation is approximately 18 kilometres west of Mooloolaba and is part of Powerlink’s 275kV transmission network between generators and the main South East Queensland load centre. Palmwoods Substation also provides the major injection point into Energex’s (part of the Energy Queensland Group) distribution network for the Sunshine Coast and north Caboolture areas.
Several secondary systems at the Palmwoods Substation are reaching the end of their technical service life and are facing obsolescence with no manufacturer support for repairs and few spares available.
In August 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 November 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 the secondary systems by July 2021. The estimated capital cost is $7.3 million in 2017/18 prices. Powerlink is the proponent of this option.
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 email@example.com.
