In 2007, the Queensland Government sold approximately 50,000 contestable electricity customers and retailer trading activities to AGL.

[6] Ergon Energy also owns and operates 33 stand-alone power stations that provide supply to communities across Queensland which are not connected to the main electricity grid.

[7][8] In regional Queensland, retail competition is limited and most customers continue to be supplied by Ergon Energy under a standard contract.
