Energy Policy WA has published the Exposure Draft of WEM Amending Rules (Miscellaneous Amendments No. 3). Amongst other amendments, this includes proposed WEM Amending Rules to:
- require AEMO to inform EPWA and the ERA of any issues that are likely to adversely affect the effectiveness of the market or achievement of the Wholesale Market Objectives;
- require AEMO to investigate and report on significant incidents in the SWIS;
- reduce the deadline for providing AEMO any final details of a Forced Outage from fifteen days to seven days after the relevant Trading Day to allow for certain settlement calculations to be performed earlier;
- allow AEMO to proactively share information with EPWA and the ERA without requiring a formal request;
- clarify the publication requirements associated with NCESS contracts;
- allow AEMO to require more reserve capacity security to be lodged in the event that security has been drawn upon due to Facility not commencing on time;
- provide clarity around the Availability Duration Gap determination for all years in the LT PASA horizon;
- amend the definitions of Enablement Maximum and Enablement Minimum to improve clarity, and ensure that Enablement Limits accurately reflect the capability of a Facility;
- modify the settlement rules to allocate the costs of NCESS Contracts for peak capacity as a Reserve Capacity cost, i.e. on the basis of IRCR;
- remove barriers to entry and encourage participation of aggregated DSPs in the RCM;
- update clause 7.4.35 to allow a Market Participant to make a Real-Time Market Submission after Gate Closure if directed to do so by AEMO;
- refine the cost allocation methodology for Contingency Reserve Raise;
- define a Facility by its Metering Point, rather than its connection point, to allow for registration of multiple Facilities behind a single connection point following approval from AEMO;
- include transitional rules to extend the timeframes related to the submission, consideration and approval of AEMO’s Allowable Revenue for the 2025 to 2028 period;
- clarify the settlement provisions related to calculating FCESS Uplift Payments; and
