Deregister from the DWGM

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

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. Clause 135AH of the National Gas Rules (NGR) outlines the requirements for the revocation of registration.

Deregistration does not affect any prior obligation or liability of the organisation under the NGR.

Application letter

Existing participants seeking to deregister must apply to AEMO in writing for a 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

    Complete the application to deregister, as outlined above, and email a copy to onboarding@aemo.com.au.

  2. AEMO review

    AEMO reviews the deregistration application. 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 notification

    AEMO notifies the participant of the outcome of their application to deregister. If successful, AEMO publishes a notice of the revocation on AEMO's website and notifies the Australian Energy Regulator (AER) and the Australian Energy Market Commission (AEMC) by email of the deregistration.

  4. Ceasing participation

    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.

Re-registering

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