AEPC_2025_04 Commissioning Tests

The Consultation Process

The consultation process is outlined below. Dates are indicative only and subject to change.  

Procedure Change Proposal

Electricity System and Market Rules – Clause 2.10

Date of Notice: 7 May 2025

Matter under Consultation

AEMO has commenced the Procedure Change Process to propose amendments to the WEM Procedure: Commissioning Tests to:

• align with system and process changes following upgrades to the Commissioning Test Portal delivered under the Outages and Commissioning Test Plans project.
• improve clarity around processes and timing for revisions and adjustments.
• provide for AEMO to request and receive advice, analysis and supporting information for the assessment of Commissioning Test Plans for new Facilities. 

On 6 February 2025 the State Electricity Objective (SEO) replaced the Wholesale Market Objectives under section 3A of the Electricity Industry Act 2004. The proposed changes contribute to the State Electricity Objective by improving the efficiency of processes for undertaking Commissioning Tests, in turn improving the safety, security and reliability of supply of electricity.

Invitation to Make Submissions

AEMO invites 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 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, 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). 

Closing Date and Time

Submissions in response to this Procedure Change Proposal should be sent by email to WA.Marketdevelopment@aemo.com.au, to reach AEMO by 5.00 pm (AWST) on 6 June 2025.

All submissions must be in electronic format (pdf or Microsoft Word) and should use the Procedure Change Submission form. 

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.
