A short note with this snapshot of a 6-hour long frequency trace on Friday afternoon 31st October 2025, to capture what looks like another VRE-induced frequency wobble earlier this afternoon:
This looks to have occurred around 14:00 (NEM time) today.
Will look into this further at some future point in time.
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.
With All Energy happening this week in Melbourne, plus the clock ticking down on preparations at the Nelson Review Panel for their final report, I’ve reached back to the NEMdev conference to write about 2 big concerns with the draft Recommendations 2A and 2B.
The (concerning) frequency spike across the NEM in the middle of the day (Tuesday 19th August 2025) has triggered many proximate questions – understandable – but also has raised these 3 Broader Questions.
