Procedure Change Proposal

Electricity System and Market Rules – Clause 2.10

Date of Notice:  21 July 2025

Matter under Consultation

AEMO has commenced the Procedure Change Process to propose a new WEM Procedure: Low Reserve Conditions, required to be developed in accordance with the requirements of clause 3.17.11 of the ESM Rules. 
AEMO’s proposed WEM Procedure documents:

• the processes AEMO will follow to identify a potential Low Reserve Condition and make a Low Reserve Condition Declaration under the:
  • Medium Term (MT) PASA horizon
  • Short Term (ST) PASA horizon; or
  • Real Time Operations Horizon.
• the levels at which AEMO would make a Low Reserve Condition Declaration, being: 
  • LOR 1; 
  • LOR 2; and
  • LOR 3.

• the notification processes and timeframes AEMO will observe when making a Low Reserve Condition Declaration.
• the process AEMO will follow to reassess a Low Reserve Condition associated with a Low Reserve Condition Declaration, made under the MT PASA or ST PASA, acknowledging increased uncertainty associated with longer-term forecasts.
• the principles and processes associated with implementing an AEMO Intervention Event or actions required under clause 7.7.4 of the ESM Rules, to resolve a Low Reserve Condition.
