Update on Callide Unit C3 partial return to servce

13 Feb 2024

The Callide C Power Station joint venture (JV) has provided an update to the market this morning about Unit C3’s return to service.

Unit C3 remains on track to return to its full capacity at the end of March however we have removed its partial return to service that was previously scheduled for the end of February.

Unit C3 has been in ‘preservation mode’ while the C3 cooling tower is being rebuilt. Throughout this time a regular inspection and maintenance program has been occurring to ensure the power station’s plant and equipment remain in good working condition to enable return to service.

This inspection program has detected carbon dust in the C3 generator which has arisen during the preservation process. To ensure safety in the return to service of the unit, the JV has made the prudent decision to fully inspect and clean the generator which will impact the return to service for partial load.

This change in return to service for C3 is unrelated to the rebuild of the cooling towers, which remains on schedule.

The dates for Unit C4’s return to service have not changed.

CS Energy is committed to the safe return to service of the joint venture-owned Callide C Power Station to support Queenslanders’ power needs and the National Electricity Market in 2024.
