Case Study of 16:05 on Friday 28th September 2018 (aggregate Raw Off-Target–333MW for Semi-Scheduled units)
This is the 12th Case Study in this series (looking at each of 98 extreme incidents). This one is simpler than the 11th Case Study!
Collections of events that we see happening in the NEM, categorised in terms of the seasons in which they occur.
This is the 12th Case Study in this series (looking at each of 98 extreme incidents). This one is simpler than the 11th Case Study!
In this 5th article in a series, we look at the impact on electricity consumption of Stage 4 Lockdown associated 'State of Disaster' in Victoria
This is the 11th Case Study in a series (looking at extreme outcomes of Aggregate Raw Off-Target for Semi-Sched units). We've rolled into 2018, now and (coincidence?) this one is much more complex than...
This is the 10th Case Study in a series working through 98 discrete dispatch intervals of extreme Aggregate Raw Off-Target for Semi-Scheduled events. This Case Study looks at only 1 of 5 occasions of...
Some quick notes today, to document high-level data (to be explored later) relating to some significantly depressed solar harvest data today due to the widespread cloud/wind event.
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...
This 8th case study in this series presents tabular results for all Semi-Scheduled DUIDs which were operational at the time of the SA System Black event.
This 7th case study in a series takes a look at 1 of 3 dispatch intervals during 2016 that saw extreme under-performance (in aggregate) across all Semi-Scheduled plant.
This 6th case study in a series takes a look at only 1 of 5 Dispatch Intervals featuring over-performance in a total of 98 that saw extreme Aggregate Raw Off-Target performance across all Semi-Scheduled...
For the 5th Case Study in this series (looking at individual outcomes of extremes in aggregate Raw Off-Target performance across all Semi-Scheduled plant) we look at an even rarer time when the aggregate discrepancy...
This morning the AEMO have called for expressions of interest for the 'Unscheduled Short-Notice RERT' for summer 2020-21.
After publishing three Case Studies on Saturday, this 4th Case Study in a long series is much more complex - with 8 different Semi-Scheduled Wind Farm units across VIC and SA exhibiting significant deviations...
Third case study today - and last one looking back at 2013. This one is a bit more complex than the first two.
Like was the case on 4th July 2013, the cause of this large Aggregate Raw Off-Target result (across all Semi-Scheduled Generators) was a single unit trip.
Does not take long to see why this particular dispatch interval was one of the few dispatch intervals (before 2019!) flagged in our top-down analysis of aggregate Raw Off-Target across all Semi-Scheduled units in...
A short review, as it happens, on a day where renewable production reached 10,000MW in aggregate across the NEM.
My participation in yesterday's session about ‘Energy Technology – performing under (heat) stress’, organised by the Australian Institute of Energy, was an opportunity to reflect on what I saw as the Four Headline Events...
Spurred by a number of concurrent requests I've returned to the pattern of prior analysis of Q2 prices (completed in 2016, 2017 and 2018) to look at what's changed for Q2 2020 that's just...
In the midst of winter, it would be easier to forget the stresses that the NEM encountered over the prior summer 2019-20. Thankfully, the Australian Institute of Energy has arranged for this discussion for...
Marcelle uses the latest release of ez2view (v7.4.5.665) to further investigate the impact of low dispatch prices in QLD on Saturday July 4 2020.
