South Australian households may use natural gas, liquefied petroleum gas (LPG), or both. Typically, natural gas is supplied via gas mains, and LPG is supplied in bottles, though in some areas it can be supplied by the gas mains.
Natural gas produced in Australia is transported long distances through transmission pipelines. It is then moved through the distribution network – in South Australia, owned and operated by Australian Gas Networks – into individual homes and businesses.
Households can choose between several gas retail companies. Gas retailers issue bills, and collect payment, which is then distributed between the various stakeholders: wholesale (17%), transmission (5%), distribution (69%), and retail companies (9%).
