CS Energy will extend the current outage of Unit C3 at Callide C Power Station by three days to enable additional pre-emptive maintenance work unrelated to the clinker incident on April 4 that saw the unit forced offline.

Acting Chair of CS Energy Jeff Seeney said while work has progressed on the Unit C3 incident repairs according to plan, engineers have taken the opportunity to inspect other areas of the boiler that would not otherwise have been accessible until the scheduled overhaul of the entire C3 Unit in August 2025.
The pre-emptive work, already underway, will correct some deterioration and cracking found in the critical high pressure steam piping which delivers steam to the turbine, which was not related to or affected by the clinker fall in the combustion chamber on April 4, 2025.
“We are following expert engineering advice to undertake this necessary work now before returning the boiler to service as it is no longer a safe choice to leave it until the scheduled shutdown in August 2025,” Seeney said.
“Following expert engineering advice and playing it safe reflects the cultural change the new Board and management is fostering at CS Energy to ensure we once again are recognised as a safe, reliable provider of electricity to Queenslanders.”
