AEPC_2025_1 Dispatch Settlement and Monitoring Data

The Consultation Process

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

Procedure Change Proposal

Wholesale Electricity Market Rules – Clause 2.10

Matter under Consultation

AEMO has commenced the Procedure Change Process to refine the drafting of the WEM Procedure for Dispatch Settlement and Monitoring Data which commenced on 1 October 2023.

Minor improvements to the WEM Procedure provide a clearer description of the procedure to be followed by Rule Participants providing settlement and monitoring data and clarify the description of methods, processes, and information AEMO will use to determine estimates to support the Relevant Level Method.

These changes better achieve the WEM Objective of promoting economically efficient electricity related services in the South West interconnected system (clause 1.2.1(a) of the WEM Rules). 

Notice of Extension to the closing date for submissions on the Procedure Change Proposal

The closing date for submissions on the Dispatch Settlement and Monitoring Data Procedure Change Proposal has been extended to 5 March 2025 in accordance with clause 2.10.17(b) of the WEM Rules. 

This procedure opened for consultation on 22 January 2025 and the consultation process was scheduled to close on 20 February 2025.  

AEMO has decided to extend consultation in recognition that some members of the AEMO Procedure Change Working Group (APCWG) did not receive the initial notification email on 22 January 2025, which was mistakenly sent to a related mailing group. The proposed WEM Procedure: Dispatch Settlement and Monitoring Data is scheduled to commence on Monday 12 March 2025.
