Procedure Change Proposal

Wholesale Electricity Market Rules – Clause 2.10

Date of Notice: 24 October 2024

Matter under Consultation

AEMO has initiated this Procedure Change Proposal for a new WEM Procedure: Reliability Standard Implementation following amendments to the WEM Rules, which included the deletion and replacement of clauses 3.3.1, 3.3.2 and 3.3.3 of the WEM Rules, arising from Wholesale Electricity Market Amendment (Tranches 2 and 3 Amendments) Rules 2020, Schedule C.

The Amending Rules, which commenced on 1 October 2023, requires a (new) Procedure under clause 3.3.2 of the WEM Rules for AEMO to set out the process it will follow to assess reliability to facilitate the operation of the South West Interconnected System (SWIS) in a Reliable Operating State.

The Procedure informs AEMO’s reasonable expectation (under clause 3.3.1 of the WEM Rules) on whether the SWIS is in a Reliable Operating State, and facilitates AEMO’s assessment of risks to Power System Adequacy and actions to mitigate any risks (under clause 3.3.3(c) of the WEM Rules).

As part of undertaking the reliability assessment, the Procedure:

• specifies the ‘planning criteria’ to be used in the various planning horizons to inform assessments of risks to adequacy;
  
• identifies the power system conditions and other factors to be taken into consideration as part of the risk assessment;
• sets-out the matters AEMO will take into account when assessing risks to adequacy as part of Outage assessment and approval; and
•  specifies what matters AEMO must, and must not, include when measuring Unserved Energy.

AEMO is seeking comment and feedback on:

• The proposed drafting for the Procedure, specifically how well the proposed drafting reflects the intent of clause 3.3.2 of the WEM Rules (which is the Head of Power), and relatedly, clauses 3.3.1 and 3.3.3 of the WEM Rules.
• Whether there are likely to be any unintended issues stemming from the proposed drafting of the Procedure.
• Any other matters of relevance to the responder.
