AEMO and Powerlink are continuing to investigate system strength requirements in North Queensland.
The system normal equations have been revised to remove Gladstone >=1 requirement.

A revision to the constraint equations will be implemented at 1200 hrs on Tuesday 4th February 2025.

The new combinations have now published in a limits advice document on AEMO's website. For more information refer to the new limits advice: https://www.aemo.com.au/energy-systems/electricity/national-electricity-market-nem/system-operations/congestion-information-resource/limits-advice

This advice contains all the combinations for Queensland for system normal cases. Additional information has been included in the limit advice to clarify the requirement to disconnect all inverters/turbines under certain system conditions.

The constraint equation in the Q-NIL set of the form below will be modified:

-Q_NIL_STRGTH_xxxx
-Q_NIL_STRGTH_xxxx_I
