A very short article for Wednesday 6th November 2024, such that we might follow up later, to note the following two wobbles in frequency in the mainland NEM today …
Frequency wobble on Wednesday morning
Here’s one that is visible in the snapshot taken at 09:18 (NEM time) this morning, looking back a 1-hour window:
Deeper Frequency wobble on Wednesday afternoon
And here’s a snapshot taken at 16:02 (NEM time) this afternoon, looking back a 2 hour window and capturing a dip that occurred
Not quite (according to what’s visible in the chart) to the edges of the Normal Operating Frequency Band (NOFB).
Paul was one of the founders of Global-Roam in February 2000. He is currently the CEO of the company and the principal author of WattClarity. Writing for WattClarity has become a natural extension of his work in understanding the electricity market, enabling him to lead the team in developing better software for clients.
Before co-founding the company, Paul worked as a Mechanical Engineer for the Queensland Electricity Commission in the early 1990s. He also gained international experience in Japan, the United States, Canada, the UK, and Argentina as part of his ES Cornwall Memorial Scholarship.
As the 5th article in an evolving series that progressively explores the (apparent self-forecasting glitch and) frequency spike on Tuesday 19th August 2025, we take an early look at Solar Farm performance.
Prior to the Brisbane session of the Nelson Review Panel (on Thu 29th May 2025) we take a look at Dispatch Error in the 16:15 dispatch interval on Monday 26th May 2025 to see who supported frequency, and who drove it the wrong direction (outside of the NOFB).
A follow-on to my earlier article of a couple weeks ago, looking at another instance where a team effort was required to counter a drop in system frequency following the loss of generation at a large power station (this time the single unit Kogan Creek power station – the largest single unit in the NEM).

Does a slight drop in frequency affect synchronise clocks and is the effect cumulative?
