Things are not currently* looking rosy for the NSW region early next week … so it’s no surprise to see AEMO asking (on Wednesday morning 20th Nov 2024) for generator recall information.
A short note to flag the apparent trip of Callide C3 just prior to 06:35 (NEM time) on Wednesday 20th November 2024.
AEMO’s MN120671 forecast LOR3 was published at 15:33 NEM time on Tuesday 19th November 2024 – so it’s worth noting that ~7 hours later, MN120698 was published – with a deeper forecast LOR3 highlighted.
On Tuesday morning 19th November 2024 the AEMO MN120612 warns of forecast Low Reserve Conditions for summer 2024-25 in both NSW and Victoria.

A short record of some evening volatility in QLD and NSW on Monday evening 18th November 2024 … with the ‘N-MNYS_5_WG_CLOSE’ constraint set a familiar factor.
It’s roughly 6 months since the decision was made to extend the life of Eraring Power Station. I’ve had a question for a while, but have only had time to look now – what does that mean, in terms of planned outages to 2027?
A very quick record of evening volatility in QLD and NSW on Friday 15th November 2024.
On Friday morning 15th November 2024 we see the return to service of both YWPS1 and LYA2 – coincident with the cancellation of Victorian directions for System Strength.
We (and others) wondered, why the direction (especially for 4 units) to replace the System Strength from the ‘missing’ coal units?
We’ve only just published ‘AEMO directs 4 units on in Victoria, to cover System Strength shortfall’ … noting that, at that time, there were 3 coal units in Victoria offline.
Our ‘Notifications’ widget in ez2view has alerted us that Loy Yang A2 unit has also come offline shortly afterwards (just prior to 09:30 NEM time).
On Thursday morning 14th November 2024, the AEMO has directed 4 different units to operate, to cover a potential system strength shortfall in the Victorian region.
We earlier noted this ‘Significant (-786MW) drop in NSW demand, on Wednesday 13th November 2024’ … and, in response, a reader (KC) asked a question that inspired this article.
A short article on Wednesday afternoon, 13th November 2024 with this snapshot highlighting a drop in frequency on the mainland.
The ‘Notifications’ widget in one of our copies of ez2view triggered an alert that we’ve not seen all that often at all, flagging a 786MW drop in ‘Market Demand’ in the period from 10:25 to 10:30 NEM time on Wednesday 13th November 2024.
Partly prompted by a comment yesterday from a WattClarity reader (Liam), and powered by ‘next day public’ data, we take a look at Yallourn Power Station on Tuesday 12th November 2024.
We’ve already looked at how there was a drop in system frequency at ~10:41 NEM time (outside of the NOFB) in conjunction with trips of units at Yallourn Power Station. Well, believe it or not there was a couple drops – not as big – later in the day.
A second quick look at the drop in NEM Mainland Frequency on Tuesday 12th November 2024.
A quick article recording the drop of NEM Mainland Frequency below the lower bound of the NOFB on Tuesday morning 12th November 2024.
