CS Energy has worked closely with the Australian Energy Market Operator (AEMO) and Powerlink Queensland to plan the return to service of the Callide C Power Station units in a safe and controlled manner.
Unit C3 returned to service this afternoon (19 January) and Unit C4 is forecast to return to service tomorrow (20 January). The market was kept informed over the weekend of the shift in the return to service dates from the original forecast of 18 January.
Our preliminary investigations have identified that an internal IT network overload caused by human error was the cause of the unplanned outage of the units on 15 January. The control system operated as designed on the day and automatically tripped the units.
We have put in place immediate corrective actions to prevent a recurrence. We will conduct a thorough investigation to confirm the root causes and will implement any further improvements identified.
Callide Power Station is comprised of two power plants, Callide B and C, each with two generating units (B1 and B2, C3 and C4).
CS Energy (through its subsidiary Callide Energy Pty Ltd) owns Callide C in a 50/50 joint venture with IG Power (Callide) Ltd. CS Energy operates Callide C on behalf of the JV.
CS Energy owns 100 per cent of the adjacent Callide B Power Station.
