QLD to NSW Interconnector (QNI) upgrade - program for inter-network tests

This is to inform all Registered Participants that the test program for the upgrade of the Queensland to New South Wales Interconnector (QNI) which deals with inter-network tests is now finalised.  The test program outlines the proposed hold points and tests to occur to validate the increased power transfer capability of QNI.

Submissions

All submissions on the test program are now closed.

Next steps

As outlined in the final test program, AEMO proposes to 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.
