5 - 3 x Stanwell, 1 x Callide B, 1 x Callide C, 3 x Gladstone, 10 x Total Stanwell+Callide+Gladstone, 4 x Kareeya: 70% output
The following new combination will also be implemented:
6- 3 x Stanwell, 2 x Callide C, 3 x Gladstone, 9 x Total Stanwell+Callide+Gladstone, 4 x Kareeya: 20% output
If these combinations are not met, Mt Emerald WF, Sun metals SF and Haughton SF have a limit of 0 MW and 0 inverters.
The constraint equations are: Q_NIL_STRGTH_MEWF, Q_NIL_STRGTH_HAUSF, Q_NIL_STRGTH_SMSF.

Revised System Strength limits in North Queensland
AEMO ELECTRICITY MARKET NOTICE
AEMO and Powerlink are continuing to investigate system strength requirements in North Queensland.
Through this work, AEMO and Powerlink have identified the need, depending on power system conditions, to constrain the output of three generators in North Queensland to maintain power system security.
The constraint equation is expected to limit generation from the three generators depending on power system conditions. The generators are Mt Emerald Wind Farm, Haughton Solar Farm and Sun Metals Solar Farm.
The constraint equations are: Q_NIL_STRGTH_MEWF, Q_NIL_STRGTH_HAUSF, Q_NIL_STRGTH_SMSF. These will be implemented at 1500hrs EST today.
The minimum generator combinations and limits are:
1 - 3 x Stanwell, 1 x Callide B, 1 x Callide C, 4 x Gladstone, 10 x Total Stanwell+Callide+Gladstone, 4 x Kareeya, 2 x Barron Gorge: 100% output
2 - 3 x Stanwell, 1 x Callide B, 1 x Callide C, 4 x Gladstone, 10 x Total Stanwell+Callide+Gladstone, 4 x Kareeya, 1 x Barron Gorge: 80% output

5 - 3 x Stanwell, 1 x Callide B, 1 x Callide C, 4 x Gladstone, 10 x Total Stanwell+Callide+Gladstone, 4 x Kareeya: 70% output
If these combinations are not met all three generators have a limit of 0 MW and 0 inverters.

As a part of the Heywood Interconnector upgrade the increase in the upper transfer limit from SA to Victoria is dependent on the commissioning of the over frequency generation scheme (OFGS). The OFGS has now been commissioned AEMO has completed and detailed analysis of power system limits at higher transfers.
AEMO will increase the Heywood limit from SA to Vic (from the current 500 MW) to 550 MW and the combined (Heywood and Murraylink) SA to Vic limit from 650 to 700 MW at 1000 hrs on 18 Dec 2019.
