WA Gas Services Information

The Gas Bulletin Board WA (GBB) and Gas Statement of Opportunities (GSOO) were formally established for the Western Australian gas market in 2013. The development of these information services was a key recommendation of the Gas Supply and Emergency Management Committee, following two major gas supply disruptions in Western Australia (WA) in 2008.

The GBB (WA) and WA GSOO were established under a suite of regulatory instruments including the Gas Services Information Act, Regulations and Rules, and are intended to improve the transparency of information and security, and facilitate competition, in the WA gas market.

AEMO is responsible for operating the GBB (WA) and developing the WA GSOO in accordance with the Gas Services Information (GSI) Rules and relevant GSI Procedures.

The first WA GSOO was published in July 2013 and the GBB (WA) became operational on 1 August 2013.

The public website for the GBB (WA) is here.

All relevant contact details for the WA Functions and the Western Australian Market Reform Program can be found in the WA Contact Card.

GBB (WA) and WA GSOO objectives

The specific objectives of the GBB (WA) and WA GSOO are to promote the long term interests of consumers of natural gas in relation to the:

  • Security, reliability and availability of the supply of natural gas in the state.
  • Efficient operation and use of natural gas services in the state.
  • Efficient investment in natural gas services in the state.
  • Facilitation of competition in the use of natural gas services in the state.
Overview of the GSI

The GSI Act also sets out the primary purpose of the GBB (WA) and WA GSOO, as follows:

  • The GBB (WA) is a website, the primary purpose of which is to publish information about short and near term natural gas supply, transmission, storage, and demand in WA. The GBB (WA) will also provide an emergency management page to assist in the management of supply disruptions. It may also include information about other fuels, and later could be developed into a platform to facilitate the introduction of buyers and sellers of gas.
  • The GSOO is an annual planning document providing a comprehensive medium to long term outlook of natural gas supply and demand in WA and natural gas transmission and storage capacity in the State.

A comprehensive explanation of the design of the GBB (WA) and WA GSOO is provided in the GSI Design Summary.
