Energy Policy WA has published the Exposure Draft of WEM Amending Rules (FCESS Cost Review Amendments). This includes proposed WEM Amending Rules to:
- require Market Participants to specify reasonable Start Decision Cutoff times in their Real-Time Market Submissions;
- clarify that Metered Schedules for Scheduled Facilities, Semi-Scheduled Facilities and Non-Scheduled Facilities are Public Information;
- implement changes to the market power mitigation framework to improve its effectiveness and improve market efficiency, by ensuring Market Participants’ offers reflect their efficient variable costs;
- make the current In-Service Capacity Only Scenario (which excludes all capacity offered as Available Capacity) the Reference Scenario;
- rename the current Reference Scenario (which includes any Available Capacity for which the relevant Start Decision Cutoff has not yet passed) the Available Capacity Scenario;
- impose an obligation on Market Participants who offer capacity as Available Capacity to monitor Pre-Dispatch Schedules and Dispatch Schedules for shortfalls in energy, Contingency Reserve Raise or Regulation Raise, and move capacity from Available Capacity to In-Service Capacity as required to alleviate any shortfalls;
- require Market Participants with Facilities accredited for RoCoF Control Service to offer their capacity into the Real-Time Market;
- introduce more efficient tiebreak methods for FCESS and energy;
- remove the payment of FCESS Uplift Payments for the provision of RoCoF Control Service;
- provide an alternative method of compensation (through Energy Uplift Payments) for Facilities constrained on by AEMO to provide RoCoF Control Service only;
- provide for Energy Uplift Payments for Facilities that are constrained on by AEMO during a period covered by a Low Reserve Condition Declaration;
- clarify the requirements for the high and low forecast Scenarios in terms of the treatment of Available Capacity;
- clarify that Energy Uplift Payments are based on In-Service Capacity Price-Quantity Pairs in Real-Time Market Offers only;
- modify the FCESS Uplift Payment calculations to avoid over-compensating FCESS providers when their enablement losses are partially or completely covered by other Real-Time Market payments;
- implement minor error corrections and enhancements across the WEM Rules.
