These exposure drafts set out proposed changes to the Wholesale Electricity Market (WEM) to continue the implementation of the WA Government’s Energy Transformation Strategy.
The Tranche 7 Exposure Draft includes proposed Amending Rules to:
- require AEMO to record details of directions issued and other actions taken during an Emergency Operating State;
- require AEMO to provide information on SESSM outcomes to the Coordinator as well as the ERA;
- modify the requirements for an Outage Plan submitted by an Impacting Participant;
- clarify the rules around the revision of Outage Plans;
- allow AEMO to relax certain timing requirements for reporting Forced Outage details for some Self Scheduling Outage Facilities;
- clarify that the Network Access Quantity Model is not required to comply with clause 4.15.9(c) if it is unable to comply concurrently with Appendix 3;
- revise the criteria used by AEMO to decide for which Facilities to determine estimates of Reserve Capacity Obligation Quantities and capacity adjusted outage quantities each Scheduling Day;
- clarify the rules around the inclusion of Constraint Equations in the Dispatch Algorithm that consider the current charge level of an Electric Storage Resource;
- extend the definition of Outage Facility Maintenance to include scenarios where a Planned Outage is required to facilitate work undertaken by other parties;
- reapply changes intended to be implemented through previously made Amending Rules that will not commence due to drafting errors in Ministerial Instruments; and
- make minor error corrections and enhancements across all the WEM Rules.
The Market Suspension Exposure Draft, which has been developed by AEMO, sets out proposed Amending Rules to enable settlement in the event AEMO suspends the Real-Time Market or fails to use the Dispatch Algorithm for the Central Dispatch Process.
