This is to inform all Registered Participants that the test program for the upgrade of the Queensland to New South Wales Interconnector (QNI) has been prepared for consultation with the Registered Participants in accordance with the requirements of Clause 5.7.7(p) of the National Electricity Rules (Rules), which deals with inter-network tests.  The test program outlines the proposed hold points and tests to occur to validate the increased power transfer capability of QNI.

Invitation to make submissions

AEMO invites written submissions in response to the draft inter-network test program document to be sent by email to internetwork.testing@aemo.com.au by 5.00pm (AEST) on 2 February 2022.

All submissions must be forwarded in electronic format.

Please identify any parts of your submission that you wish to remain confidential and explain why. AEMO may still publish that information if it does not consider it to be confidential but will consult with you before doing so.

Please note that material identified as confidential may be given less weight in the decision-making process than material that is published.

Submissions received after the closing date and time will not be valid, and AEMO is not obliged to consider them. Any late submissions should explain the reason for lateness and the detriment to you if AEMO does not consider your submission.

All submissions will be published on AEMO’s website, other than confidential content.


In your submission, you may request a meeting with AEMO to discuss the matter under consultation, stating why you consider a meeting is necessary or desirable.

If appropriate, meetings may be held jointly with other Consulted Persons. Subject to confidentiality restrictions, AEMO will generally make details of matters discussed at a meeting available to other Consulted Persons and may publish them.

Next steps

Following consultation, the final test program will be published online at least 20 business days prior to commencement of tests.

As outlined in the draft test program, AEMO proposes to update keep the market up to date during the commissioning period as follows:

  • Market Notices will be issued giving notice of the intended commissioning of the QNI upgrade works and the intended start of the inter-network tests.
  • During active testing, a Market Notice and/or communication will be issued to advise when a series of tests will be conducted.  This will be done weekly, with daily updates if the test schedule changes.  As dispatch for testing will be achieved through the market systems, the market impact of the scheduled test will be evident to market participants through pre-dispatch and dispatch schedules.  
  • If it is necessary to vary a test procedure, in a manner that AEMO reasonably considers does not differ materially from that stated in this Program, AEMO will advise the market of the reason for the change through established communications.  
  • At the end of testing at each test hold point a final Market Notice will be issued by AEMO to advise when the increased capability of QNI (as defined by the hold point) ceases to be subject to Inter-network test conditions and is released to the Market.  This step is at AEMO’s discretion and will follow consideration by AEMO of a report on the results of all damping measurements and disturbance tests for that hold point.
