AEMO has made a Draft Determination on the fee structures to apply to gas participant fees, and the Pipeline Capacity Trading Exchange Fees and Auction Fees, from 1 July 2021. In developing its Draft Determination AEMO has carefully considered the issues raised in its Consultation Paper; stakeholder views on the Consultation Paper; further internal analysis and discussion; and National Gas Rules (NGR) fee structure requirements. AEMO now seeks stakeholder views on its draft determination.

The current structure came into effect on 1 July 2018 for Participant Fees and 1 March 2019 for Pipeline Capacity Trading (PCT) services. The fees for these services will expire on 30 June 2021.

AEMO is required to review and publish the structure and term of participant fees to apply from 1 July 2021, in accordance with the extended consultative procedure under the NGR, and in consultation with Registered participants, interested parties and such other persons as AEMO thinks appropriate.

Fee structures for PCT were introduced after AEMO’s last determination on Participant Fees and were necessary to support new services introduced in early 2019 as a result of the gas pipeline capacity trading reform.  These fees are recovered as Exchange Fees and Auction Fees under the Rules but are considered together with participant fees through this consultation given the similar consultation requirements and term expiry dates, and benefits of taking a holistic view of gas fees.

The review considers the following AEMO markets and services:

Participant fees:

  • Declared Wholesale Gas Market (DWGM)
  • Short Term Trading Market (STTM)
  • Retail markets
      • Vic
      • NSW/ACT
      • Qld
      • SA
  • Gas Bulletin Board (GBB)
  • Gas Statement of Opportunities (GSOO)
  • Energy Consumers Australia (ECA) Fees.

PCT fees:

  • Capacity trading platform (CTP)
  • Day-ahead auction (DAA)
  • Registration fee (CTP and DAA)
  • Operational Transportation Service (OTS) Code Panel.

AEMO has made a Draft Determination on its future gas fee structures and is accordingly seeking stakeholder views on this.

The closing date for submissions to this Draft Determination is Thursday, 4 February 2021.
