Following a control system fault, Units C3 and C4 at the Callide Power Station had to be taken offline yesterday at 4.55pm. This was done in conjunction with Powerlink Queensland to ensure the safety of the process.
Standard safety procedures were followed, including a precautionary evacuation of all personnel to the evacuation point on site for approximately 20 minutes.
We are working with the original equipment manufacturer of the control system to investigate the root cause of the fault.
Both C station units are currently forecast to return to service in a staged manner on 18 January. This is subject to change as we learn more about the incident and any remedial work required.
Callide’s other two generating units (Units B1 and B2) remain online.
