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). However, there are times when unplanned outages are required.

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.

At times, the Kareeya and Barron Gorge hydros are taken out of service to allow for maintenance activities to take place. While every effort is made to plan these works in advance, there are times when unplanned outages are required.
