Also worth noting in the same bundle of analysis is Friday 20th January 2023, which looked as follows (in terms of Aggregate Raw Off-Target across Semi-Scheduled units:
We see that, from around the time the sun rose on the day the vast majority of dispatch intervals feature collective under-performance. But this flips from around 15:25 with a bunch of instances of over-performance seen together, with the largest being AggROT = -497MW at 16:25 on the day.
This is another event that might be further explored in subsequent extensions to this Case Study.
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.
Following from the release of GenInsights21, in this article we look at some of what that analytical publication can help us understand, in terms of how the changing market is impacting on the role that renewables will increasingly play in the NEM in the years to come.
One example of where forecasting wind output seemed to be more difficult than we would hope it could be. Something to be further explored in the Generator Report Card.
This 9th case study in this series advances us into October 2017, where we see another example of an extreme outcome for collective under-performance. Most notably this happens across 5 Wind Farms (with one unit completely tripping).
A quick article highlighting how the trend in aggregate number of unit starts, across the whole of the NEM, highlights the scale of one of the core underlying changes (and challenges) facing us in the NEM’s energy transition.
