Procedure change proposal
Electricity System and Market Rules – Clause 2.10
Date of Notice: 13 November 2025
Matter under consultation
AEMO commenced the Procedure Change Process to propose amendments to the WEM Procedure: Declaration of Bilateral Trades as a result of Schedule 2 of the Wholesale Electricity Market Amendment (RCM Reviews Sequencing) Rules 2025. These Amending Rules specify how Facilities can nominate Facility Technology Types which are Electric Storage Resources or Energy Producing Systems as a Fixed Price Component.
The Amending Rules were gazetted on 14 January 2025. Schedule 2 commences at 8:00 AM (AWST) on 1 January 2026.
The contents on the Procedure reflect the relevant clauses of the ESM Rules (including as amended) and AEMO’s requirements in relation to the development of this Procedure. Minor editorial changes were also made.
The Procedure is consistent with the SEO as it relates to Power System Reliability, price outcomes, and reducing greenhouse gas emissions. To the extent permitted under the ESM Rules, the Procedure is technology agnostic, allowing for low emissions technologies.
Invitation to make submissions
AEMO invited written submissions on this Procedure Change Proposal, including any alternative or additional proposals that may improve the procedure or better meet the SEO under section 3A of the Electricity Industry Act 2004.
AEMO requested that respondents identify any parts of their submission that they wished to remain confidential, explaining why. AEMO advised that it may still publish that information if it does not consider it to be confidential, but will consult with you before doing so.
When making a claim for confidentiality, AEMO encouraged respondents to familiarise themselves with Chapter 10 of the Electricity System and Market Rules, which imposes obligations in respect to the release of documents.
Meetings
AEMO advised that, before the closing date for submissions, any person may request a meeting with AEMO to discuss the issues and proposed changes raised in the Procedure Change Proposal, stating why they consider a meeting is necessary or desirable.
If appropriate, meetings may be held jointly with other stakeholders.
Subject to confidentiality restrictions, AEMO generally makes details of matters discussed at meetings available to other stakeholders as part of the final published Procedure Change Report (or earlier, where applicable).
Closing date and time
AEMO advised that submissions in response to this Procedure Change Proposal should be sent by email to [email protected], to reach AEMO by 5.00 pm (AWST) on 11 December 2025.
AEMO advised that all submissions must be in electronic format (pdf or Microsoft Word) and should use the Procedure Change Submission form.
AEMO noted that it is not obliged to consider submissions received after the closing date and time. Any late submissions should explain the reason for the delay and the detriment to you if AEMO does not consider your submission.
