After a little over a week away, I’m striving to skim and scan many different data sources with respect to the ‘what did I miss?’ question – and the following late afternoon weakness in system frequency (on Sunday 30th November 2025) jumped out at me:
At some point in future we might be able to look into:
The extent to which under-performance of VRE was a factor:
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.
In Part 3 of this series with respect to Thursday 16th October 2025, we focus on when a large collective under-performance across all Semi-Scheduled Wind Farms and Solar Farms dragged the frequency outside the NOFB – down at 49.824Hz at 16:49:07.6.
To provide some more colour about what’s been happening on Thursday 17th October 2024, here’s a snapshot of NEM Mainland frequency at 15:07 (NEM time) looking back only 15 minutes.
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).
