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.

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.

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.
First article today, recording a new ‘lowest ever’ point for demand in Victoria (Sun 31st Dec 2023), and possible intervention from AEMO has it looks to drop further, leading to possible grid instability.
