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.
With GenInsights Quarterly Update for 2023 Q4 completed, and some time till the end of 2024 Q1, we’ve looked back at Tuesday 14th November 2023 (when AEMO had concerns about low System Strength in NSW) and looked at the level of inertia actually seen in the grid. A useful Case Study to say ‘what would have happened without Eraring?’
Drawing from GenInsights Quarterly Update for Q4 2022, and the next version of our ez2view software, we take a look at the *current* expectations for closure of Liddell Power Station (within weeks) and Eraring Power Station (in 2025). A segue into this week’s update to the ESOO, perhaps?
[PART 2 of] a post by guest author, Bruce Miller – which was initially posted on LinkedIn as one piece, but which has been broken into two on WattClarity as each part serves different purposes.
