Procedure change proposal
Electricity System and Market Rules – Clause 2.10
Date of Notice: 9 May 2025
Matter under consultation
AEMO commenced the Procedure Change Process to propose amendments to the RCM Limit Advice Requirements WEM Procedure to:
- Clarify the content, form and format of RCM Limit Advice.
- Improve alignment with the Wholesale Electricity Market Amendment (Reserve Capacity Reform) Rules 2023, which were updated to include:
- Clause 4.4B.2(e) which requires AEMO to provide forecasts of peak demand for the third Capacity Year of the Long Term PASA Study Horizon.
- Clause 4.4B.7 which requires AEMO to provide updated information under 4.4B.2, following the outcome of the application process for Certified Reserve Capacity.
- Clause 4.4B.9 which requires each Network Operator to provide updated information under 4.4B.5.
- Improve alignment with the Wholesale Electricity Market Amendment (RCM Reviews Sequencing) Rules 2025, which were updated to include clause 4.4B.9(f), requiring Network Operators to provide a list of substation names and associated Transmission Node Identifiers that are expected to be in service on 1 October of Year 3 of the Reserve Capacity Cycle.
- Undertake minor editorial improvements, including conversion to AEMO’s most recent Procedure template, amendments to improve readability, correcting minor typographical errors, and updating clause referencing.
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 considered the Procedure is consistent with the SEO.
