Some wobbles in System Frequency (NEM mainland) through the middle of the day on Thursday 31st October 2024 stick out, and will be progressively explored.
A deeper look at the frequency data (our own, and also from some others) reveals a number of other interesting things about what happened on Tuesday 25th May 2021 in Queensland.
In this article we take a look at operations of Waratah BESS through August 2025 – including some large Dispatch Errors on several days:
(a) including Fri 29th Aug 2025, and how WTAH1 apparently helped to drive frequency the wrong way;
(b) and Tue 19th Aug 2025, where WTAH1 helped to restrain frequency.
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 ?
