Procedure change proposal
Electricity System and Market Rules – Clause 2.10
Date of Notice: 30 September 2026
Matter under consultation
The proposed changes to WEM Procedure: Commissioning Tests to improve the process AEMO uses to assess a Commissioning Test Plan.
The proposed changes to the Procedure:
- enable AEMO to seek advice from the Network Operator in respect of a Commissioning Test Plan, to inform AEMO’s assessment of whether to approve or reject a plan (or a revised plan); and
- clarify that, for a specified risk factor, AEMO must consider any previous reactive power studies undertaken by the Network Operator or request that the Network Operator perform such studies within a specified time frame.
The Procedure is also amended to comply with the new WEM Procedure template and to improve descriptive accuracy by:
- updating references; and
- correcting terminology and typographical errors.
On 6 February 2025 the State Electricity Objective (SEO) replaced the Wholesale Market Objectives under section 3A of the Electricity Industry Act 2004. Following an assessment, AEMO considers the Procedure is consistent with the SEO. Further information is provided in the Procedure Change Proposal below.
Invitation to make submissions
AEMO invites written submissions on this Procedure Change Proposal, including any alternative or additional proposals may improve the Procedure or better meet the State Electricity Objective under section 3A of the Electricity Industry Act 2004.
AEMO requests that respondents identify any parts of their submission that they wish to remain confidential, explaining why. AEMO advises that it may still publish that information if it does not consider it to be confidential, but will consult with the respondent before doing so.
When making a claim for confidentiality, AEMO encourages respondents to familiarise themselves with Chapter 10 of the Electricity System and Market Rules (ESM Rules), which imposes obligations in respect to the release of documents.
Meetings
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).

AEMO is not obliged to consider submissions received after the closing date and time. Any late submissions should explain the reason for delay and the detriment expected if AEMO does not consider the late submission.
