Registration is a key process and this section (including the navigation items to the left) provides information and links for those looking to participate in the National Electricity Market (NEM).

Participant categories

To participate in the NEM, including associated trading activities conducted by AEMO under the National Electricity Rules (NER), you must register in one or more participant categories.

Registering in multiple markets

Participants may register in multiple markets under one ABN; or have multiple ABNs, requiring unique participant IDs for each ABN.

Registering multiple functions

An organisation with a single ABN can perform multiple functions and have single or multiple participant IDs.

An organisation conducting business under multiple ABNs must register the functions for each ABN.

Third-party authority

Applicants must provide a letter of authority if they require AEMO to liaise with a third party at any stage of the registration process. This authority will allow AEMO to disclose information about your application with your nominated third party.

The letter of authority should be sent by email and post to the Onboarding team either with your application, or beforehand.

Registered participants

You can view the current registration and exemption list containing all registered participants in the NEM, registration applicants, registrations that are ceasing or suspended, information about generators and scheduled loads, ancillary services, and registration exemptions.
