Business-to-Business Working Group

MarketRetail Meetings

The Business-to-Business Working Group (B2B-WG) has been established by the Information Exchange Committee (IEC) to provide advice to the IEC on issues and opportunities relating to the B2B framework, Procedures and Guide and to develop changes to these where necessary on behalf of the IEC.

The B2B-WG is distinct from the Power of Choice Business-to-Business Working Group (POCB2B-WG), which was created to oversee B2B changes for the Power of Choice reforms and has since been disbanded.

Terms of reference


The B2B-WG consists of five members which represent each of the B2B participant categories: namely, distributors, metering business, and retailers. AEMO provides secretariat services to the B2B-WG. A full list of current B2B-WG members is published below.

Deferred Power of Choice tranasctions

During the implementation of Power of Choice (PoC) project, 51 potential transactions that were not considered at the time to be a high-priority were deferred for later review. The Information Exchange Committee, in conjunction with its Business-to-Business Working Group, has now finalised its review of these deferred potential transactions.

Of the 51 items reviewed:

  • Ten items have been incorporated into a consultation package on B2B Procedures
    that will commence in late 2019.
  • Nineteen items are adequately addressed by existing transactions and require no
    additional actions and have been closed.
  • Seven potential transactions do not have sufficient volumes to merit progressing at
    this time. These will be monitored by the B2B-WG on an annual basis, commencing
    in late 2020.
  • Two potential transactions are dependant on changes to standing data and will be
    included on a B2B change register to be considered when AEMO reviews its standing
  • Three of the potential changes relate to MSATS rather than B2B. These transactions
    will be addressed by the Australian Energy Market Commissions’s proposed changes
    to embedded networks or have been referred to AEMO for consideration.
  • Ten of the proposed transactions were not within the remit of B2B Procedures or the
    B2B Guide, but rather should be the subject of bilateral commercial agreements
    between specific participants, or jurisdictions. These potential transactions have been
