Organisations that intend to participate in the WEM must first register with AEMO.

To register as a rule participant, the following forms must be completed and provided to Market Operations (WA):

• Application for WEMS Access Form
• WEMS Market Participant Administrator (MPA) Nomination Form

Once submitted and approved by AEMO, you will have access to the Market Participant Interface (MPI) to begin the next steps in the rule participant registration process.

As a pre-requisite to registering as a rule participant, the applicant must ensure they have submitted through the MPI:

• General contact information of the participant.
• Financial information relating to the participant.
• Market customer standing data (if applicable).

The next step requires the payment of the registration fee and a few additional forms to be submitted to AEMO:

• Application for participant registration (this is completed through the MPI).
• Recipient Created Tax Invoice Agreement.
• Declaration of Rule Participant Registration.

If assistance is required to complete the rule participant registration process, please contact Market Operations (WA) at wa.operations@aemo.com.au or call 1300 989 797.
