Further delays for beleaguered CQ power operation

The Callide C Power Station joint venture has announced further delays in the return to service of Unit C4, out of action since an explosion in May 2021 that left almost half a million people without power. Cooling towers at the plant, outside Biloela, have also undergone a rebuild following the structural failure of a section of the Unit C3 cooling tower in late 2022. CS Energy chief executive officer Darren Busine said the change in date from July 22 to August 31 for C4's return was necessary to provide additional time for testing and quality assurance.

The final electrical rectification works on C4 have been completed and construction of the new C4 cooling tower is progressing to schedule.

The power station is at the centre of a political storm over the generating unit's failure. Opposition leader David Crisafulli has slammed the circumstances surrounding the 2021 explosion at the plant as one of the greatest scandals seen in Queensland for a long time and accused the Labor Government of ‘the mother of all cover-ups’. Callide Power Station is comprised of two power plants, Callide B and C, each with two generating units (B1 and B2, C3 and C4). Units B1, B2 and C3 are all generating electricity.
