Callide Unit C4 recovery
The safety and wellbeing of our people is our priority following the incident in Unit C4 at Callide Power Station.
On 25 May 2021 an incident occurred on Unit C4, which resulted in an explosion, substantial damage to the unit and forced it offline. Shortly afterwards Callide’s other operating units tripped and went offline.
Our first priority was to make sure workers and the Callide site were safe. The power station was fully evacuated and nobody was injured.
Since then, our focus has been on helping our Callide team deal with this incident and safely bring the power station’s other units back online.
After a tremendous effort involving more than 300 employees and contractors, both Callide B station units were returned to service in June and Unit C3 in July.
An independent investigation has been commissioned to understand what caused this incident, so that we can learn from it and prevent it from happening again.
CS Energy is committed to understanding the facts that led to the C4 event so we can learn from it and improve the safety of our people and plant.
Forensic engineer Dr Sean Brady has been engaged to lead an external, independent investigation and review. Dr Brady is based in Queensland and recently completed the Brady Review, an investigation into the causes of fatalities in the state’s mining and quarrying industry.
Alongside this independent investigation, there are other stakeholders investigating what has occurred at Callide, including Workplace Health & Safety Queensland and the Australian Energy Market Operator.
The safety and wellbeing of our staff continues to be our key priority throughout this process.
