Energy Policy WA (EPWA) published an Exposure Draft of the Individual Reserve Capacity Requirement (IRCR) adjustment for Associated Loads Amending Rules for consultation.
EPWA was required to make changes to the three remaining schedules of the Wholesale Electricity Market (WEM) Amendment (Reserve Capacity Reform) Rules 2023 (the RCM Reform Rules) to allow for AEMOs revised implementation schedule and to address drafting issues identified.
During this process, EPWA identified that a necessary change requires further consultation, and therefore, developed the below Exposure Draft which includes proposed Amending Rules to specify how AEMO must estimate the contribution of each Associated Load to the change in Withdrawal of the relevant Demand Side Programme (DSP), where the DSP was dispatched during one of the Peak or Flexible IRCR Intervals.
These rules are included in the Wholesale Electricity Market Amendment (RCM Reviews Sequencing) Rules 2025 which were approved by the Minister for Energy on 9 January 2025 and published in the Government Gazette on 14 January 2025.
A copy of the of Exposure Draft of the IRCR adjustment for Associated Loads Amending Rules can be found below.
Stakeholder feedback on the Exposure Draft closed 8 October 2024.
Exposure Draft of WEM Investment Certainty and RCM Review Amending Rules
EPWA, in consultation with AEMO, has developed changes to the three remaining schedules of the RCM Reform Rules to provide for AEMO’s revised implementation sequence of these schedules and to address identified drafting issues.
EPWA has developed for consultation an Exposure Draft of WEM Investment Certainty and RCM Review Amending Rules to address the issues identified during the re-sequencing of the RCM Reform Rules that require further consultation.
This Exposure Draft contains two parts. Part 1 outlines the draft WEM Amending Rules to implement the review outcomes for Initiatives 1 and 2 of the Wholesale Electricity Market (WEM) Investment Certainty (WIC) Review.
Part 2 is to consult on changes that would allow for an earlier implementation of the Relevant Level Method, and address issues that EPWA, in consultation with AEMO, has identified during the re-sequencing of the RCM Reform Rules, which require further consultation. These include:
- a transitional provision to delay the commencement of certain obligations related to Flexible Reserve Capacity if there is an excess of Flexible Capacity Credits to allow AEMO to bring the implementation of the Relevant Level Method forward;
- additional changes to the determination of the Individual Reserve Capacity Requirement (IRCR) of Associated Loads that are part of a Demand Side Programme dispatched during an IRCR Interval, which were previously consulted on in the Exposure Draft of the IRCR adjustment for Associated Loads Amending Rules; and
- changes to clauses previously consulted on under the Wholesale Electricity Market Amendment (Miscellaneous Amendments No 3) Rules 2024 that will be implemented together with the remaining RCM Reform Rules schedules.
A copy of the Exposure Draft can be found here.
The window for submitting feedback closed at 5:00pm on 9 December 2024. Stakeholder feedback has been considered and EPWA’s response to submissions received is available below.
