Since this web page was published, the Wholesale Electricity Market (WEM) Rules have been renamed the Electricity System and Market (ESM) Rules, and the Electricity Industry (Wholesale Electricity Market) Regulations 2004 (WEM Regulations) have been renamed the Electricity Industry (Electricity System and Market) Regulations 2004 (ESM Regulations). Changes have not been made to this web page to reflect this updated name.
In July 2020, the Energy Transformation Taskforce published draft Amending Rules for a new Chapter 3A and Appendix 12 of the Wholesale Electricity Market (WEM) Rules. The draft Amending Rules relocate generator performance standards and associated negotiation frameworks from Western Power’s Technical Rules to the WEM Rules. The purpose of the change is to accommodate an improved compliance regime and allow for the Australian Energy Market Operator (AEMO) to have an equal role (along with Western Power) in the negotiation of standards for generators connecting to the South West Interconnected System (SWIS). Submissions closed on 28 August 2020.
The new Chapter 3A and Appendix 12 initially apply to Market Participants connecting new generation to the transmission network. Draft GPS Transitional Rules have now been released, outlining the process for Market Participants with existing transmission connected generating systems to meet the requirements of the new Chapter 3A by determining registered standards and developing a suitable self-monitoring plan.
The first draft of the GPS Transitional Rules was released on 2 September 2020, with revisions made following an industry consultation forum on 9 September 2020. Stakeholders are now invited to provide written submissions by 28 September 2020.
