… but more recent developments have prompted us to link directly to it here, as something that will be of interest to readers at WattClarity®, particularly as it speaks directly to their application in the NEM.
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.
Last week’s notable under-frequency load shedding in Great Britain following what appears to be the loss of two generation units in quick succession prompts me to publish some of the analysis of aggregate levels of inertia supplied by synchronous generators in South Australia as part of the Generator Report Card.
A brief, belated and back-dated article to point to this AEMO White Paper ‘Application of Advanced Grid-scale Inverters in the NEM’ published in August 2021.
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.
[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.

From my reading of the report, they say the models say they should work well – excluding “niggles” like close-in fault current behaviour. As those in the power industry know, there is a massive difference between models and actual proven near 100% reliable performance under myriad fault behaviours – many which weren’t covered in contingency planning. The non-credible events – with Callide being a good example.
Just how much importance is to be placed on preventing blackouts? Would you stake lives on the risk that they won’t fail to do their job? I wouldn’t.
