Western Australia's retail gas market was deregulated in 2004. In the wholesale gas market, participants enter into agreements with gas suppliers and pipeline operators to purchase and transport gas, which they then on-sell and supply to end-users.
The retail gas market is administered by the Australian Energy Market Operator (AEMO). The ERA is responsible for the oversight of the Gas Retail Market Scheme.
The Gas Services Information (GSI) Rules govern the operation of the Gas Bulletin Board (GBB), Emergency Management Facility (EMF) and preparation of the Gas Statement of Opportunities (GSOO). The ERA monitors participants’ compliance, investigates alleged breaches of the GSI Rules and determines AEMO’s allowable revenue and forecast expenditure for this function.
