Registration Processes for the New Market

This page provides guides, templates and other documentation related to registration process for the new Real-Time Market in the WEM.


As part of WEM Reform there will be changes to the registration and participant framework, which will:

  • facilitate the participation of new technologies and configurations in the WEM; and

  • allow provision of more granular registration information to support scheduling and dispatch.

For all existing Rule Participants to continue their participation in WEM they must submit new registration applications to provide data required for the new market. 

Below is the relevant information for existing Rule Participants and candidate Rule Participants to ensure they meet their transitional registration requirements to be ready for New WEM Commencement Day.

What do participants need to do?

Review the below sections in relation to Transitional registration: 

  1. Registration Schedule - to be aware of when application submission deadlines are.
  2. Excel applications forms (Optional) - to gain provisional approval of Facility data prior to entering your application in the Registration (SCED) interface within WEMS MPI.
  3. Submit applications via Registration (SCED) interface (Mandatory) - to gain final approval of Facility data and complete Facility registration for the new Real-Time Market.
  4. Other registration forms (Optional) - to submit other registration forms for the new market (e.g. Facility Aggregation/ Disaggregation, Facility Class reassessment Forms, and NDL association form for Interruptible Loads).
