Given that it produced some pretty (significant and) strange outcomes in the NEM on the day (as noted in this initial article at the time) we’ll be reviewing this with keen interest… thanks to the WattClarity readers who alerted us about this!
… and, mainly for our own future reference as we find navigation on the AEMO website could be improved, this report is listed under ‘Scheduling Error Reports’ here.
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 the AEMO releasing the 2022 ESOO on Wednesday morning 31st August 2022 with the limited time I have available right now I’ve had a quick look, and in this article highlight some things that jumped out to me.
Sunday 15th August saw lowest level of Operational Demand in the NEM for a winter period, NEM-wide. This also led to a number of other outcomes (including higher renewable penetration, negative prices, … and chatter on social media).
The National Electricity Market (NEM) is designed to operate at 50 Hz. Frequency deviation occurs when generation and load are mismatched. It is important in a lightly meshed and long network such as the NEM to maintain tight frequency control and that frequency response is available throughout the network.
