AEMO updates ‘Minimum System Load’ alert for VIC on Saturday 28th Sept 2024 … trending down towards MSL2

Already this morning we have posted two articles:

1)  With ez2view snapshots from 05:35, we posted ‘Low, getting lower … AEMO’s forecasts for ‘Market Demand’ on Saturday 28th September 2024’; and then

2)  We posted ‘Updated long-term trend of Victorian minimum demand’ to show how low the forecasts were for Saturday 28th September 2024 in the context of history.

Since that time we’ve had a window of ez2view open with the ‘Forecast Convergence’ widget updating in real time, looking at successive forecasts from AEMO for ‘Market Demand’ in Victoria for tomorrow.  Here’s a zoomed in view of how it currently looks:

Remembering this widget allows the user to ‘look up a vertical’ in order to see ‘that other dimension of time’, we can see that the forecast for ‘Market Demand’ in Victoria at 12:00 tomorrow (NEM time) in the forecast run at 10:00 this morning was that it would be 1,420MW:

1)  and that this was also the case in the run produced at 09:00 as well;

2)  the forecast AEMO publishes for 11:00 has not yet arrived, so we’ll be interesting to see whether (and how) it has changed.

But, no real surprise that (at 10:55) the AEMO updates its ‘Minimum System Load’ warning for Victoria for tomorrow via MN118475:

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.
