Power Station Outages
Unplanned outages
At CleanCo, safety is our priority. While we work hard to ensure the reliability of our assets, unplanned outages can occur from time to time. In these moments, our immediate focus is on returning to a safe and stable operating state—protecting people, the environment, and our assets every step of the way.

Planned Outages
Routine maintenance activities are required to enable the ongoing safety and reliability of our assets. These maintenance activities, which require the generators to be taken out of service, are planned in advance and in consultation with the Australian Energy Market Operator (AEMO).
Outages typically involve one generation turbine coming offline at a time, full outages where all turbines are offline are scheduled on a 4-5 year cycle.

Natural river flows remain unaffected by outages.
Water releases to enable generation will be reduced during outages dependent on the number of turbines that are offline. For example, at Kareeya during a partial outage when one turbine is offline, the power station can generate max 66MW, releasing 66ML down the river.
