Register as a Rule Participant in the WEM

This page provides an overview of the processes and tasks required to register as a Rule Participant in the Wholesale Electricity Market (WEM).

Further information on how to apply are outlined in the WEM Procedure for Rule Participant Processes.

Registration occurs in two high level stages:
