This is the 13th Case Study in this series (looking at each of 98 extreme incidents). We're looking at an event on 15th October 2018 that seems to heavily feature high-wind cut-out as the...
This is the 13th Case Study in this series (looking at each of 98 extreme incidents). Note I have skipped 2 events earlier in 2018 and will come back to publish case studies of...
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!
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...
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...
Following on from the article posted on the day, here's a focused look at what can be seen in ('next day' public) data for Yarranlea Solar Farm on Friday 1st May 2020 - a...
This is the 2nd of 4 Case Studies to follow on from Tuesday’s main article (summarising results across 105,120 dispatch intervals through 2019 for ‘all Coal’ and ‘all Wind’ groupings). In this case, let's...
Following on from Tuesday's main article (summarising results across 105,120 dispatch intervals through 2019 for 'all Coal' and 'all Wind' groupings), this is the first of 4 x Case Studies that look at each...
There are a number of reasons why we're completing the analysis we are sharing via WattClarity - here are two big ones.
Third case study in a growing series - on this occasion looking at the (extreme - and possibly excessive?) lengths taken by Tailem Bend Solar Farm to avoid being dispatched at times of negative...
Our second Case Study in a recent series, aimed to help us explore ways to continue the pushing the development of ez2view forward, but also shared with readers here on WattClarity. This time about...
Thursday 10th October 2019 presented another day of many negative price events in the QLD region. In this Case Study (prepared for dual purposes) we look at how one particular solar farm operated through...
