Maintaining compliance with performance standards applicable to Haymarket substation secondary systems
TransGrid has recently published a Project Consultation Specification Report for maintaining compliance with performance standards applicable to Haymarket substation secondary systems.
Haymarket 330/132 kV substation was commissioned in 2004. Along with other key substations including Rookwood Road and Beaconsfield, it forms part of TransGrid’s network that serves the Sydney Central Business District. Haymarket substation supplies the Inner Sydney area including Sydney CBD, whereas Beaconsfield substation supplies Sydney’s Eastern suburbs.
The secondary systems at Haymarket substation have reached a condition that reflects the end of serviceable life. As it is superseded by new technology at the manufacturer level and the existing technology becomes obsolete, spare parts become scarce and the ability of the any primary asset connected to the substation to reliably operate will be at risk.
TransGrid has put forward for consideration two credible options that would meet the identified need from a technological and project delivery perspective. The combined on-site replacement of the protection and control systems is the most economical and preferred option at this stage of the RIT-T process.
The estimated capital cost of the proposed preferred option is $12.2 million.
In accordance with the requirements of the Rules, a summary of the Project Specification Consultation Report is made available on the AEMO website. A copy of the Project Specification Consultation Report can be obtained from TransGrid Website on the RIT-T Consultations page or by emailing RIT-TConsultations@TransGrid.com.au
Submissions in response to this Project Specification Consultation Report are required by the closing date of 26 August 2019.
