CS Energy has begun a scheduled overhaul of Unit C4 at the jointly owned Callide C Power Station as part of its asset management program under the Queensland Government’s Electricity Maintenance Guarantee.
The Unit C4 major overhaul is running from 10 April to 26 June and will include more than $60 million in expenditure towards a range of statutory inspections, maintenance and other works to support its reliable and efficient operation.
The works will also deliver an economic boost to the Biloela region by bringing up to 250 overhaul contractors to the site, providing flow-on benefits to local service industries such as machinery companies, hospitality, and transport businesses.
It is estimated that more than $13 million will be spent with local suppliers across Central Queensland during the overhaul.
The overhaul follows a strong performance by CS Energy’s portfolio over the March quarter where it achieved more than 95 per cent average availability (for the period 1 January to 31 March 2026).
Acting CS Energy Chief Executive Officer Tony Bellas said the overhaul involved many months of planning and preparation.
“CS Energy is working closely with our major contracting partner Downer to deliver this overhaul, as well as Intertek, Toshiba, CQ Techs, Multivalve and other subcontractors,” Mr Bellas said.
“Our priority is delivering this overhaul safely, on time and on budget, so that Callide C can continue to support Queensland’s energy needs.”
The overhaul of Unit C4 includes statutory compliance work, inspections and repairs of high pressure energy piping, generator circuit breaker mid-life overhaul, control system upgrade, and replacement of air heater baskets and fabric filter bags.
