Register a Facility in the WEM

Participants in the Wholesale Electricity Market (WEM) must register a Facility where it is connected to the South West Interconnected System (SWIS); exemptions are listed in the Market Rules.

This page provides an overview of the processes and tasks required to register a Facility in the WEM. As with Rule Participant registration, this occurs in two steps: firstly, creating the facility in the Wholesale Electricity Market System (WEMS); then, once this is approved by AEMO, applying for Facility registration.

The Facility registration process can only begin once the applicant organisation has been registered as a Rule Participant.
