Powerlink has recently published a ‘Project Specification Consultation Report’ (PSCR) to maintain power transfer capability and reliability of supply at Lilyvale.

Lilyvale Substation, located approximately 50km from Emerald, plays a critical role in the supply of electricity to customers in Queensland’s Central West region, as well as the Blackwater and Bowen Basin mining areas.

Planning studies have confirmed there is a long-term requirement to continue to supply the existing electricity services provided by Lilyvale.

Commissioned over 38 years ago, much of the substation’s primary plant, including two of the original three 132/66 kV transformers, are reaching the end of their technical service lives and are no longer supported by the manufacturer, with limited spares available to rectify a failure if one were to occur.

The proposed preferred option that is considered to satisfy the Regulatory Investment Test for Transmission (RIT-T) involves the replacement of two 132/66kV 80MVA transformers with two 160MVA transformers and the full bay replacement of primary plant in selected bays by October 2022. 

The indicative capital cost of the RIT T project for the preferred option is $26.27 million in 2018/19 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 are required by the closing date of 21 August 2019.
