Outages
CS Energy operates and maintains our assets to ensure they are available to provide affordable, reliable and sustainable electricity for Queenslanders.
We carry out regular planned outages to perform statutory maintenance and overhauls of our generating units.
Unplanned outages can occur from time to time, and when this occurs, our priority is carrying out the repairs safely, while also working to minimise plant downtime wherever possible.
