• Gas information services

    The Public Utilities Office (formerly the Office of Energy) has worked with the Independent Market Operator (IMO) on the development and implementation of the Gas Services Information Project. The IMO lead the establishment of (and now operates) the Gas Bulletin Board (GBB) and Gas Statement of Opportunities (GSOO) in Western Australia. The GBB and GSOO will improve the flow of information across the gas supply–demand chain for existing and potential market participants.

    The Gas Bulletin Board went live on 1 August 2013 and the initial GSOO was published by the IMO on 26 July 2013.

    Objectives of the GBB and GSOO are to:

    • improve the security, reliability and availability of natural gas supplies in WA
    • promote the efficient operation and use of natural gas services
    • provide information to allow efficient investment in natural gas services
    • encourage competition in the natural gas services supply chain.


    After two major gas disruptions in 2008, WA’s Gas Supply and Emergency Management Committee reviewed the security of gas supplies and how future disruptions might be managed or mitigated. The former Minister for Energy agreed with the Committee’s recommendations to establish two initiatives, and selected the Independent Market Operator (IMO) to implement them.

    • Gas Bulletin Board (GBB) – a website with near-term system and market information on gas production, transmission, storage capacity and demand. It also provides an Emergency Management Facility to give government and industry additional assistance in managing gas supply disruptions.
    • Gas Statement of Opportunities (GSOO) – a comprehensive document produced by the IMO each year. It contains medium to long-term outlook of gas supply and demand in WA, and highlights potential future commodity shortfalls or transportation constraints.



    The Gas Services Information Act 2012 received Royal Assent on 10 April 2012. This enabling legislation sets-up the governance framework for the GBB and GSOO, including the development of regulations and the Initial Rules.

    The Gas Services Information Regulations 2012 were gazetted on 29 June 2012. The regulations formalised the IMO’s selection as the Operator of the GBB and GSOO and conferred upon the Operator the function of establishing the GBB and GSOO.

    The Minister amended the regulations in April 2013 to provide the heads of power necessary for the operation of the GBB and GSOO. Final amendments were gazetted in late June 2013.

    Initial Rules

    The Public Utilities Office engaged Marchment Hill Consulting across 2012 to consult with stakeholders on the information requirements for the GBB and GSOO.

    The IMO established the interim Gas Advisory Board in December 2011 to help develop the Initial Rules for the operation of the GBB and GSOO. The board comprised gas industry stakeholders, a small end-user representative and representatives of the IMO. The Public Utilities Office and the Economic Regulation Authority attended interim Board meetings as observers.

    Further information on Rules design and implementation can be found on the IMO website [external website].

    The Initial Rules were made by the Minister for Energy and gazetted in June 2013.

    With the coming into force of the initial Rules and Regulations, the interim Gas Advisory Board completed its task and was dissolved. A new Gas Advisory Board to oversee Rules evolution was established under the Rules.

    Emergency Management Facility Consultation

    The Public Utilities Office together with the IMO consulted with Gas Emergency Planning Committee (GEPC) members in May 2012 on the specific information requirements for the Emergency Management Facility (included on the GBB). This work assisted in the development of the initial Rules, with additional consultation undertaken by the IMO across 2012 and 2013.
