From the 12:05 dispatch interval, today’s series of SMS alerts has started from the 12:05 dispatch interval (NEM time) announcing new ‘lowest ever*’ points for ‘Market Demand’ in NSW.
At 11:15 (NEM time) on Sat 26th Oct 2024 the NEM-wide ‘Market Demand’ is already down at only 9,909MW (i.e. already lowest ever).
At 09:01 (NEM time) on Saturday 26th October 2024 the AEMO has published MN119423 to update their forecast for MSL1 today in Victoria

With forecasts for a very, very low level of ‘Market Demand’ tomorrow (Sat 26th Oct 2024) in NSW, here’s a longer term trend to show how it would fit in context.
It was only 5 days (on Sunday 20th October 2024) when we saw a new ‘lowest ever*’ point for ‘Market Demand’ in NSW … so we’re amazed to see AEMO forecasting a low point for tomorrow (Sat 26th Oct) a fully 15% lower than that ‘lowest ever’ point.
Specifically with respect to All Energy 2024, I can categorically state that the ‘Operating in the NEM’ session that was conducted on Thursday 24th October 2024 was easily the best* session I attended throughout the event.

The GB01 unit (the back-up genset that has been supporting the Broken Hill area the past few days) has come offline overnight – early Friday 25th October 2024:.
It’s not (yet?) a frequent occurrence, so worth noting that AEMO has directed 2 units at Murray to synchronise and operate as a synchronous condenser from 08:00 (NEM time) on Thursday 24th October 2024 (to protect against low System Strength)
It’s Wednesday morning and the backup generator in Broken Hill (GB01) has run successfully through the night after restarting Tuesday afternoon 22nd October 2024.
