Callide Unit C3 returns to service

02 Apr 2024

Unit C3 at Callide C Power Station is generating electricity following its return to service over the Easter long weekend.

CS Energy brought C3 back online yesterday afternoon (1 April) following a thorough commissioning process to test the unit and its new cooling tower over recent weeks.

CEO Darren Busine said employees and contractors had put in an enormous effort to reach this milestone.

"This is a significant milestone in returning our portfolio to full capacity,” Mr Busine said.

“Getting to this point is thanks to the combined effort of the construction crews that built the new Callide C3 cooling tower and our operations team who have been methodical in their approach to re-commissioning the unit.

“The Callide team will closely monitor the unit as it undergoes further testing and commissioning works before gradually returning it to its full capacity over the coming week.”

Callide C’s other generator – Unit C4 – will make a staged return to service beginning on 30 June 2024 (200 MW) before returning to full capacity (420 MW) on 31 July 2024.
