On Thursday 29 October 2026 from 12-1pm, CleanCo will conduct an audible test of new emergency warning sirens in the area downstream of Splityard Creek Dam in the Somerset region. This is a test only. There is no emergency. Residents do not need to take any action if they hear the sirens.
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.

| Kareeya Hydro | U1 – Unavailable | 20/7/2026 | U1: 25/11/2026 | Units may be derated or in outage during this period. | Partial Availability |

CleanCo endeavours to update the Australian Energy Market Operator (AEMO) and the CleanCo website concurrently, however there may be times when updates to the CleanCo website are delayed. Please refer to CleanCo Queensland Limited’s AEMO forecast reporting on the AEMO website for the most up-to-date information.
Units may be de-rated, from time to time, as a result of environmental or other variables, such as insufficient water to run hydro or pumped-hydro generators, or excessive heat and humidity impacting Swanbank E. De-rating refers to a temporary reduction to the unit’s maximum output capacity.
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.
