Revenue by generation type
AGL's revenue from thermal coal generation increased 2% from $3,813 million in FY22 to $3,901 million in FY23 due to the increase in wholesale electricity prices in New South Wales and Victoria, partly offset by lower generation due to the closure of Liddell Power Station in April 2023 and AGL Loy Yang outages. AGL's revenue from renewable generation increased 25% from $537 million in FY22 to $673 million in FY23 primarily driven by higher generation volumes at the Victorian hydroelectric power stations due to significant rainfall in the region, partly offset by lower wind generation due to outages at Macarthur Wind Farm in Victoria.

NR: Not reported
AGL’s revenue from thermal coal generation is derived by: multiplying the proportion of total generation output (GWh) to the pool that was sourced from thermal coal power stations by the total revenue of AGL’s electricity sales to the pool, plus AGL’s revenue from sales of brown coal from AGL’s Loy Yang Mine.
AGL’s revenue from gas generation is derived by: multiplying the proportion of total generation output (GWh) to the pool that was sourced from gas generation power stations by the total revenue of AGL’s electricity sales to the pool.
AGL’s revenue from renewable generation is derived by: multiplying the proportion of total generation output (GWh) to the pool that was sourced from wind farms, hydroelectric power stations and solar farms by the total revenue of AGL’s electricity sales to the pool.
A breakdown of AGL’s total generation output sold to the pool by fuel source is reported in AGL’s FY23 Annual Report.
