AGL sells electricity to just under 2.1 million households, or over 22% of Australia's residential customers, according to 2021–22 figures. AGL joined the Australian market in 1837, supplying gas for street lamps, and claims to have a proud heritage of innovation. AGL speaks toward sustainability in its media pages, claiming approximately 20% of the total generation capacity within Australia's National Electricity Market.

AGL was established in 1837 and currently has over 2 million residential customers - it is a publicly owned entity, which means it is partially Australian owned. Its head office is in Sydney with a call centres in Adelaide and Melbourne.

It is one of the few energy retailers that is climate active. However, the company owns and operates coal, gas, battery, hydro, solar and wind energy. It operates large coal-fired power stations and gas-fired power plants.
