• Gas pricing

    The Western Australian Government regulates natural gas prices for small use customers (consuming less than one terajoule per annum) serviced by gas distribution systems in the Mid West/South West, Kalgoorlie-Boulder and the Albany supply areas. A gas retailer must have a gas trading licence issued by the Economic Regulation Authority to sell gas to these customers. The Energy Coordination (Gas Tariffs) Regulations 2000 provides for a regulated price cap on the tariffs that retailers can charge small use customers.

    The regions within which the regulated price cap apply includes Geraldton and surrounding areas, Carnamah, Perth metropolitan area extending north to Gingin and south to Busselton. Regulated gas tariffs do not apply to the reticulated LPG systems in Margaret River, Leinster and Esperance, or to bottled gas.

    Gas retailers that supply large users are not bound by the regulated price cap.

    In addition to the regulated price cap on gas tariffs, gas retailers may charge additional fees. The Government does not regulate these additional charges.

    Choice of Retailer

    Small use customers can chose to buy natural gas from any licensed gas retailer. In addition to Alinta Energy, the following gas retailers currently sell gas in the Mid-West/South-West areas:  AGL Energy, Kleenheat, Origin Energy and Perth Energy. Licensed retailers cannot charge above the regulated price cap when offering to supply small-use customers under a standard form contract.  However, retailers can offer lower prices through non-standard form contracts.

    More information on gas supply options is available from each licenced gas retailer’s websites below:
