Equivalent availability factor
The high performance of AGL's generation fleet during the first three quarters of FY22 was challenged by the confluence of planned and unplanned outages in Q4. In FY22, the overall fleet availability, (termed Equivalent Availability Factor), improved compared to FY21. The performance of Loy Yang A Power Station was ahead of the FY22 target despite the Unit 2 generator failure in Q4. Unit 2 will return to service in September 2022 with an improved design to ameliorate the failure mechanism. Bayswater Power Station’s FY22 performance was on par with FY21. The extensive mid-life program for Unit 3 was completed in July 2022. This will provide improved generation capability and efficiency, together with upgraded design features. Liddell Power Station’s FY22 performance improved compared to FY21. Unit 3 was removed from service in Q4 and a simplified operational regime has been implemented to ensure the continued safe operation of the remaining units until closure in Q4 FY23.
Notes
Equivalent Availability Factor (EAF) measures the percentage of rated energy available when required.
Barker Inlet Power Station is included from FY21 onwards.
Silverton Wind Farm is included from FY22 onwards.
Kwinana Swift Power Station has not been included.
Wind farms (Tilt Renewables) comprises Silverton Wind Farm. Coopers Gap Wind Farm is not included.
Wind farms (non-Tilt Renewables) comprises Oaklands Hill, Wattle Point, Macarthur, Hallett, Hallett Hill, North Brown Hill and The Bluff wind farms.
Overall EAF is weighted by megawatt (MW) capacity.
