Procedure Change Proposal

Wholesale Electricity Market Rules – Clause 2.10

Date of Notice: 18 May 2020

This notice informs all Rule Participants and interested parties (Consulted Persons) that AEMO has published a Procedure Change Proposal concerning revisions to the Market Procedure: Reserve Capacity Security (Procedure) and is conducting a consultation process on this proposal.

This consultation is being conducted in accordance with the Procedure Change Process detailed in clause 2.10 of the Wholesale Electricity Market Rules (WEM Rules).

Matter under Consultation

The matters under consultation are proposed amendments to the Market Procedure: Reserve Capacity Security developed under clauses 4.13.8 and 4.13A.23 of the WEM Rules.

The Minister for Energy amended the WEM Rules on 11 February 2020 to implement changes to the Reserve Capacity Price from the 2019 Reserve Capacity Cycle (RCM Pricing Amendments). Further information about the changes can be found on Energy Policy WA’s website.

The RCM Pricing Amendments introduced a requirement for Demand Side Programmes (DSP) to provide DSM Reserve Capacity Security each year. In accordance with clause 1.29.2 of the WEM Rules, DSM Reserve Capacity Security provisions must be documented in a Market Procedure by 1 July 2020.

This Procedure Change Proposal includes:

  • Amendments required to document DSM Reserve Capacity Security.
  • Changes to reflect the Reserve Capacity Security Guideline, which was introduced to clarify the current version of the Market Procedure following requests from Market Participants. This guideline will be replaced by the amended Market Procedure.

Further details are provided in the Procedure Change Proposal published with this notice. The proposed revised Market Procedure is published with this notice and the Procedure Change Proposal.
