Procedure Change Proposal

Wholesale Electricity Market Rules – Clause 2.10

Date of Notice: 11 November 2022

Matter under Consultation

The purpose of the Reserve Capacity Mechanism is to provide price signals for investment in the Wholesale Electricity Market (WEM), thereby facilitating the efficient entry or exit of capacity to ensure Power System Security and Power System Reliability is maintained. The accurate assignment of Certified Reserve Capacity (CRC) is critical to provide those price signals, and to ensure reliability of supply in the South West Interconnected System.

On 23 September 2022, due to a combination of issues including ongoing fuel supply limitations, AEMO called for tenders from potential suppliers of supplementary capacity for the upcoming Hot Season (1 December 2022 to 31 March 2023). This has highlighted the need for AEMO to take additional steps in our assessment of fuel availability for the 2022 Reserve Capacity Cycle CRC process.

Given the importance of the CRC process for the WEM and Market Participants, AEMO proposes to amend the Procedure to:

• specify additional information a Market Participant must provide as evidence of fuel availability in its CRC application under clause 4.10.1(e)(v)(2) of the WEM Rules; and

• clarify the matters AEMO may consider when determining its reasonable expectation of the amount of capacity likely to be available under clause 4.11.1(a) of the WEM Rules.

AEMO has also taken the opportunity to make some minor and administrative changes.

Further details are provided in the Procedure Change Proposal published with this notice. The proposed amended Procedure is also published with this notice.
