Equivalent availability factor

In FY25, AGL’s overall fleet Equivalent Availability Factor (EAF), was 79.1%, down 6.7 percentage points compared to FY24. This was primarily driven by a decrease in generation at Loy Yang A due to the planned Unit 4 major outage (compared to no major outages for Loy Yang A in FY24) and unplanned outages at Bayswater in the second half of the year.
