Monitoring the new WEM

In preparation for the commencement of the new Wholesale Electricity Market (WEM) design on 1 October 2023, the ERA conducted a series of public consultations to inform its Offer Construction Guideline and Trading Conduct Guideline for market participants.

These Guidelines provide regulatory guidance on how market participants can fulfill their general trading obligations under the Electricity System and Market (ESM) Rules.

Following the commencement of the new WEM, Energy Policy WA made a series of changes to the ESM Rules, resulting in further changes to the guidelines. With each set of changes, the ERA conducted further consultation, which is detailed below.
