The Western Australian retail gas market became fully contestable in 2004. This means gas companies can compete in the marketplace for all Western Australian gas customers, including residential customers.
Multiple gas trading and retail companies operate across the regional and metropolitan areas, servicing industrial and residential customers.Gas trading licences
Gas retailers need a gas trading licence from the Economic Regulation Authority to sell gas to small use customers (residential and small business customers using less than 1 terajoule of gas a year).
A Retail Market Scheme enables a retail market administrator to manage the gas market.
A gas retailer must be a member of an approved Retail Market Scheme to sell gas to customers through a gas distribution system, when there are already one or more companies selling gas through that system.
In Western Australia, there is one Retail Market Scheme that covers all of ATCO Gas Australia’s distribution systems. The Australian Energy Market Operator is the scheme administrator. The Economic Regulation Authority has regulatory oversight of this scheme as well as any future Western Australian schemes.
