AGL has a diverse power generation portfolio including base, peaking and intermediate generation plants, spread across traditional thermal generation (gas and coal) as well as renewable sources (including hydro, wind, landfill gas and biogas).

AGL's power generation assets are predominantly located within the regions where its retail customers are generally located.

AGL's renewable energy generation assets comprise around 40% of our generation portfolio.

The operational characteristics of AGL's hydro assets are valuable during periods of high demand as full generation output can be achieved very quickly (in as little as two minutes at some stations), thereby rapidly offsetting potential exposure to the potentially high spot prices that AGL would otherwise face.

The gas fired generation assets provide an important reinforcement to the hydro assets because they are able to provide AGL with sustained operation if water (the fuel source for the hydro assets) becomes constrained. AGL's bidding of generation into the National Electricity Market (NEM) is aimed at minimising the cost of electricity purchases across the entire wholesale electricity portfolio.

The fuel diversity benefits provided by AGL's power generation portfolio, which includes renewable and zero greenhouse emission assets, assist in reducing the carbon intensity of the portfolio.
