In the prior article we noted the tripping of four separate units (three at Yallourn – possibly due to some network issues). So we’ve guessed which-sat-where in the time-series frequency trace.
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.
Friday 31st January 2025 (appeared to) experienced a very large drop in demand in NSW in a single dispatch interval – but we’re now suspecting some form of data/operational glitch. However we wonder, if there was ~1,000MW more energy injected into the grid than required over a sustained period, what stopped the frequency flying through the roof?
Partly prompted by a comment yesterday from a WattClarity reader (Liam), and powered by ‘next day public’ data, we take a look at Yallourn Power Station on Tuesday 12th November 2024.
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
