Procedure Change Proposal

Wholesale Electricity Market Rules – Clause 2.10

Date of Notice: 14 February 2025

Matter under Consultation

AEMO has commenced the Procedure Change Process to propose amendments to the Certification of Reserve Capacity Procedure, as a result of the Wholesale Electricity Market Amendment (RCM Reviews Sequencing) Rules 2025 (Amending Rules).

Schedule 1 of the Amending Rules introduced a new Flexible Capacity product in time for the 2025 Reserve Capacity Cycle, to incentivise capacity that can start, stop and ramp quickly.

AEMO has proposed the following amendments to the Procedure to ensure consistency with the Amending Rules:

• Amendments to outline the processes Market Participants must follow when applying for Flexible Certified Reserve Capacity.
• Amendments to outline the processes AEMO must follow when assessing applications and assigning Flexible Certified Reserve Capacity.
• Changing “Certified Reserve Capacity” to “Peak Certified Reserve Capacity” where relevant, as the definition for Certified Reserve Capacity now includes both Flexible Certified Reserve Capacity and Peak Certified Reserve Capacity.

AEMO has also proposed the following minor amendments to the Procedure:

• Minor updates to Table 1, including introducing a definition for Significant Maintenance.
• Amendment to clarify the specific application requirements where major modifications are completed or intended to be completed to an existing Separately Certified Component.
• Amendment to clarify how AEMO will calculate Forced Outage rates when a Facility is not assigned Capacity Credits during the relevant period.
• Amendment to clarify how a Component or Facility Upgrade will be assessed in relation to the fuel nominated in the Certified Reserve Capacity application.
