STPASA - Forecast Minimum System Load 1 (MSL1) in the VIC Region on 12/10/2024

AEMO ELECTRICITY MARKET NOTICE

AEMO has detected that there is an elevated risk of insufficient demand to maintain a secure operating state in the Victorian region from 1200 hrs 12/10/2024 to 1400 hrs 12/10/2024.

Minimum regional demand is forecast to be 1646 MW at 1300 hrs, and the advisory threshold is:

o MSL1 - 1815 MW
o MSL2 - 1315 MW
o MSL3 - 815 MW

MSL events are forecast when forecast regional demand is less than the relevant MSL threshold. The forecast regional demand is below the MSL1 threshold.

Minimum System Load 1 (MSL1) in the VIC Region on 28/09/2024

AEMO ELECTRICITY MARKET NOTICE

Update to Market Notice 118421.

AEMO has detected that there is an elevated risk of insufficient demand to maintain a secure operating state in the Victorian region from 1030 hrs to 1430 hrs 28/09/2024.

Minimum regional demand is forecast to be 1420 MW at 1200 hrs, and the advisory threshold is:
- MSL1 - 1865 MW
- MSL2 - 1365 MW
- MSL3 - 865 MW

MSL events are forecast when forecast regional demand is less than the relevant MSL threshold. The forecast regional demand is below the MSL1 threshold.

Refer to NEM Data Dashboard to monitor demand levels: https://aemo.com.au/energy-systems/electricity/national-electricity-market-nem/data-nem/data-dashboard-nem

AEMO is seeking a market response.

An insufficient market response may require AEMO to take action or intervene to maintain power system security in Victoria. This may result in action such as the direction of scheduled production units, curtailment of non-scheduled production units, and/or a direction to maintain regional demand above required MSL threshold, in both Victoria and South Australia.

Update to system normal constraint equation in NSW for transient voltage stability in south-west NSW

AEMO ELECTRICITY MARKET NOTICE

Refer to market notice 92840.

Transgrid has advised AEMO of an update to the transient voltage stability limit in south-west NSW for loss of Darlington Point to Wagga (63) 330 kV line. The limit will include terms for the Darlington Point and Riverina BESS.

The following constraint equation will be updated with the above changes at 1100 hrs Friday 20th September 2024.
N::N_NIL_63

For full details on the formulation, the new constraint equation has now been loaded into AEMO's pre-production systems.

For further details on these constraint equation please contact ben.blake@aemo.com.au

Update to system strength constraints in North Queensland

AEMO ELECTRICITY MARKET NOTICE

Refer to market notice 110677

AEMO and Powerlink are continuing to investigate system strength requirements in North Queensland.
Due to commissioning of new feeder 8905 (H13 Ross - H39 Woree) 275kV line in Far North Queensland, the system normal system strength equations for low North Queensland demands and all Karreya stations out of service conditions have been revised.

A revision to the constraint equations will be implemented at 1400 hrs on Tuesday 20th February 2024.

The new system strength 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.

Below constraint equations in the Q-NIL set will be modified:

- Q_NIL_STRGTH_KBWF
- Q_NIL_STRGTH_KBWF_I
- Q_NIL_STRGTH_HAUSF
- Q_NIL_STRGTH_HAUSF_I
- Q_NIL_STRGTH_MEWF
- Q_NIL_STRGTH_MEWF_I
