A short note to flag the apparent trip of Callide C3 just prior to 06:35 (NEM time) on Wednesday 20th November 2024, as captured in this alert from the ‘Notifications’ widget inside of ez2view at the time:
A quick reference back to our live and high-speed frequency window for the mainland NEM (from readings in Brisbane) show the effect of the trip in a drop in frequency:

It’s now seven months since the SCADA outage on Sunday 24th January 2021 – and we’re finally able to complete and publish this (quite long) article exploring some of the implications for units on the LHS of the ‘Q>>NIL_CLWU_RGLC’ constraint equation
Looking back at system frequency, we see a noticeable drop in system frequency around ~15:45 (NEM time) on Saturday 5th October 2024.
(a) There’s no large trip of a coal unit that coincides
(b) But it *might be* the result of a large collective under-performance (relative to Target) across the Semi-Scheduled fleet NEM-wide ?
