Our History


Since creation in 1837, we are proudly one of Australia's oldest companies and from the beginning, AGL has always asked the question, 'what next'?

"What new technologies can be developed to provide safe, sustainable and reliable energy to more people? What new ways can we support the communities we operate in? What can we do to help our customers reduce their energy usage and their environmental footprint? 

From turning on the first gas street lamp in Sydney in 1841, to building Australia’s largest solar plant in 2015, we're very proudly the largest ASX listed owner, operator and developer of renewable energy generation in the country. And as an active member of the community, we're also proud to contribute to support organisations such as The Smith Family, St Vincent de Paul Society and Cancer Council Australia.. 

Today, our business definition is to 'harness insights to enrich the customer's energy experience'

AGL is one of Australia’s leading integrated energy companies. It is taking action to responsibly reduce its greenhouse gas emissions while providing secure and affordable energy to its customers. Drawing on over 175 years of experience, AGL serves its customers throughout eastern Australia with meeting their energy requirements, including gas, electricity, solar PV and related products and services. AGL has a diverse power generation portfolio including base, peaking and intermediate generation plants, spread across traditional thermal generation as well as renewable sources including hydro, wind, solar, landfill gas and biomass.
