Deregister from the DWGM

A registered participant in the Declared Wholesale Gas Market (DWGM) can apply to AEMO to be deregistered from any registrable capacity. This process is referred to as revocation.

This page provides an overview of the deregistration requirements and process.

What you need to deregister

Existing participants seeking to deregister must apply to AEMO for revocation of registration. The application should be on a formal letterhead and must be signed by a duly authorised company officer. Generally, this officer would hold an executive management position such as Chief Executive Officer or Company Secretary.

The application should include:

  • The participant’s full name and ABN.
  • Relevant gas Company ID(s) (if applicable).
  • The market and capacity (or capacities) from which the participant wishes to deregister.
  • The business reason(s) why the participant considers it is, or will be, no longer required to be registered in the relevant categories under the National Gas Rules.
  • A preferred future deregistration date. AEMO cannot guarantee this date but will seek to meet the time frame provided.

The deregistration process

  1. Complete and submit the application

    Complete the application to deregister as outlined above, email a copy to onboarding@aemo.com.au (preferred) and send the original to:

    Australian Energy Market Operator Ltd
    Registration Team
    Level 2, 20 Bond Street
    Sydney NSW 2000

  2. AEMO reviews the application to deregister

    Depending on circumstances, AEMO may require additional information to verify the reasons for deregistration and to confirm that any ongoing liability in the market will be met.

  3. AEMO notifies the participant

    AEMO notifies the participant of the outcome of their application to deregister.

  4. AEMO publishes notice of revocation

    AEMO will publish a notice of the revocation on our website and will notify the Australian Energy Regulator and the Australian Energy Market Commission of the deregistration.

  5. Organisation status is changed in the system registers

    Upon deregistration, the status of the organisation is changed in the various system registers maintained by AEMO. Approximately six to nine months after the date of deregistration, when all revisions have been settled:

    • data sharing to and from the deregistered participant ID is removed,
    • access to AEMO's market systems by the deregistered participant ID is revoked, and
    • subsequently produced statements and reports are disabled.

    Deregistration does not affect any prior obligation or liability of the organisation under the relevant market rules.


To re-register, the organisation must complete the registration process.
