Back on 20th July 2023, Jonathon Dyson wrote the article ‘Let’s talk about inertia’ as part of the process of focusing readers on an increasingly important power system parameter.
1) This is something that we’ve been highlighting in Appendix 1 in GenInsights Quarterly Updates reports … and will surely feature when we come to reviewing 2024 Q1; and
2) It’s something AEMO has been publishing at a regional level for a shorter period of time.
With a trip of four large synchronous units in Victoria (all supplying large amounts of inertia) it’s no surprise to see that inertia levels fell significantly this afternoon in Victoria:
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.
Inertia is an important concept to understand as the technology mix in the NEM evolves during the energy transition. In this article, Jonathon Dyson talks about the importance of inertia and highlights an example of a specific incident where we observed relatively low levels of inertia in the NEM.
AEMO also published something else today which (whilst not as publicised as the ESOO) will be of keen interest to many stakeholders in South Australia…
Just under 3 weeks ago (on 22nd April 2021) the AEMC published a draft determination that would establish ‘Fast Frequency Response’ as an additional (i.e. 9th and 10th) FCAS service in the NEM. We take a brief look.
