UPDATE (1/4/2024) - Unit C3 has returned to service.
The Callide C Power Station joint venture (JV) informed the market today of a minor change in the return to service of Unit C3 from 31 March 2024 to 7 April 2024.
The rebuild of the new Unit C3 cooling tower is nearing completion and re-commissioning of the C3 generator is underway.
The change in the return to service date is required to allow time to address minor equipment issues which have arisen during the re-commissioning process of C3. It is not unusual for issues to arise when a generating unit is returned to service after an overhaul or outage.
Once Unit C3 is back online, the unit will be closely monitored before safely and methodically returning to full capacity in a staged manner in the succeeding days.
