WEM Reform Procedures

The WEM Rules are operationalised through the WEM Procedures. WEM Procedures contain more procedural and methodological detail than the WEM Rules and are amended more frequently. 

Under the pre-reform WEM Balancing Market arrangements, AEMO was required to create and publish Power System Operations Procedures (PSOPs) and Market Procedures, which outline operational and administrative processes and place obligations on both AEMO and Rule Participants as required under the WEM Rules. WEM Reform brings significant changes to the WEM including changes to the WEM Rules and AEMO’s functions. As a result, AEMO is required to make significant amendments to 26 existing Market Procedures and PSOPs (now referred to as WEM Procedures) and create approximately 24 new WEM Procedures.  

You can view WEM Reform published and provisional procedures below, along with those currently under consultation.  A full list of all procedures to be updated under WEM Reform and the publication timeline can be found here.
