Powerlink has published a Project Specification Consultation Report (PSCR) to maintain reliability of supply and address condition risks at Ingham South.
Ingham South Substation was established in 2005 to replace the original Ingham substation equipment and provide an injection point into the Ergon Energy distribution network.
The primary switchgear and secondary systems at Ingham South Substation have been identified as being in poor condition or at the end of their technical service lives, with identified obsolescence issues. The condition of the substation’s primary switchgear – the equipment through which the electrical power passes – has significantly deteriorated, with a high number of associated defects and obsolescence issues, increasing the risk to supply in the Ingham area.
Secondary systems are the control, protection and communications equipment that are necessary to operate the transmission network and prevent damage to primary systems when adverse events occur. Many of the secondary systems at Ingham South Substation are nearing the end of their technical service lives and have become or are becoming obsolete, where they are no longer supported by the manufacturer and have only limited, or no, spares available.
The PSCR identifies replacement of hybrid switchgear modules in-situ with air insulated switchgear, and replacement of secondary systems in a new control building by 2028 as the preferred option. The indicative capital cost of the RIT-T project for the preferred option is $25.6 million in 2025 prices.
In accordance with the requirements of the National Electricity Rules, a summary of the PSCR is made available on the AEMO website. A copy of the PSCR can be obtained from the Powerlink website on the RIT-T Consultations page or by emailing networkassessments@powerlink.com.au.
Submissions are due by close of business Friday, 5 September 2025.
