Powerlink and Ergon Energy have published a Project Assessment Conclusions Report (PACR) to address the risks arising from the condition of key network assets providing electricity services to Kamerunga, Cairns and the northern beaches area in northern Queensland.
The primary plant, transformers and secondary systems at Kamerunga Substation are nearing the end of their technical service lives with identified condition and obsolescence issues. The substation is also susceptible to major flooding events which could result in damage to equipment leading to loss of supply. The Woree to Kamerunga 132kV transmission line was first established in 1963. The line operates in an aggressive tropical environment and is nearing the end of its technical service life with the majority of structures exhibiting signs of degradation.
Powerlink has developed two credible network options to address the Kamerunga Substation and Woree to Kamerunga transmission line condition risks and compliance obligations.
- Option 1 – Rebuild of transmission line with Overhead/Underground Alignment and Greenfield Air Insulated Switchgear (AIS) (new 22kV switchboard) at Kamerunga Substation.
- Option 2 – Rebuild of transmission line with Underground Alignment and Greenfield AIS (new 22kV switchboard) at Kamerunga Substation
The indicative capital cost of the preferred option (Option 1) is $292.4 million in 2025/26 prices.
In accordance with the requirements of the NER, a summary of the PACR is made available on the AEMO website. A copy of the PACR can be obtained from the Powerlink website or by emailing [email protected].
