Reserve Capacity Cycle timetable
On 13 January 2023, AEMO published the 2023 Reserve Capacity Cycle timetable as part of the 2023 Request for Expressions of Interest process under the Wholesale Electricity Market (WEM) Rules.
Following the publication of the previous deferral of the 2023 Reserve Capacity Cycle timetable on 3 May 2023, AEMO consulted with Market Participants on a further deferral to this timetable.
On 12 June 2023, AEMO notified Market Participants of an additional deferral to the 2023 Reserve Capacity Cycle timetable with respect to the 2023 WEM Electricity Statement of Opportunities (ESOO) publication date and subsequently, other Reserve Capacity activities. The updated timetable will allow sufficient time to ensure accuracy of the NAQ model inputs and outputs, which is a new consideration in the 2023 WEM ESOO report.
AEMO would like to thank Market Participants for their feedback which was generally supportive of the proposed deferred dates for the 2023 Reserve Capacity Cycle timetable.
2023 Current and Deferred Reserve Capacity Cycle timetable
On 18 February 2022, AEMO published the 2022 Reserve Capacity Cycle timetable.
The Network Access Quantity (NAQ) framework, which accounts for constrained network access, has been implemented for the 2022 Reserve Capacity Cycle. The results from the NAQ framework will be used to assign Capacity Credits for the 2022 Reserve Capacity Cycle, and are inputs to the 2023 WEM ESOO reliability assessment.
To allow sufficient time to ensure accuracy of the NAQ model inputs and outputs, AEMO proposed deferring the remainder of the dates associated with the 2022 and 2023 Reserve Capacity Cycle timetables.
Clause 1.36B (a transitional rule) sets out the process for determining and modifying the 2022 Reserve Capacity Cycle timetable. In accordance with clause 1.36B.7 of the WEM Rules, AEMO formally consulted with Market Participants on the proposed deferrals for the 2022 Reserve Capacity Cycle timetable. AEMO also consulted with Market Participants on the proposed deferred dates for the 2023 Reserve Capacity Cycle timetable. The consultation period closed on 19 June 2023, and AEMO received one formal submission from Alinta Energy as part of the consultation process.
AEMO has decided to defer the dates as proposed for the 2022 Reserve Capacity Cycle timetable.
AEMO is still considering its position with respect to the 2023 Reserve Capacity Cycle timetable and will notify stakeholders of the outcome at a future date.
The revised 2022 Reserve Capacity timetable is published below.
