Case Study of 02:35 on Saturday 15th September 2018 (aggregate Raw Off-Target +355MW for Semi-Scheduled units)
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...
Case Study of 22:40 on Monday 18th December 2017 (aggregate Raw Off-Target -310MW for Semi-Scheduled units)
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...
Solar production suffers significantly (NEM-wide) today with widespread cloud and rain event
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.
Case Study of 19:25 on Thursday 5th October 2017 (aggregate Raw Off-Target +305MW for Semi-Scheduled units)
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...
Case Study of 16:20 on 28th September 2016 (aggregate Raw Off-Target +894MW for Semi-Scheduled units)
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.
Case Study of 13:10 on Thursday 23rd June 2016 (aggregate Raw Off-Target +320MW for Semi-Scheduled units)
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.
Case Study of 04:30 on Thursday 8th January 2015 (aggregate Raw Off-Target -314MW for Semi-Scheduled units)
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...
Case Study of 16:35 on Wednesday 15th October 2014 (aggregate Raw Off-Target +443MW for Semi-Scheduled units)
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...
5-minute settlement – Why it makes such a difference to utility scale storage in Australia’s National Electricity Market
Guest author, Warwick Forster, examines the delayed but impending move to 5-minute settlement for the NEM and the potential effects on utility scale storage.
AEMO tenders for Short-Notice RERT Panel for Summer 2020-21
This morning the AEMO have called for expressions of interest for the 'Unscheduled Short-Notice RERT' for summer 2020-21.
Case Study of 03:25 on Tuesday 5th April 2016 (aggregate Raw Off-Target +359MW for Semi-Scheduled units)
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...
Case Study of 03:10 on Saturday 28th September 2013 (aggregate Raw Off-Target +331MW for Semi-Scheduled units)
Third case study today - and last one looking back at 2013. This one is a bit more complex than the first two.
Case Study of 12:35 on Wednesday 14th August 2013 (aggregate Raw Off-Target +391MW for Semi-Scheduled units)
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.
Case Study of 14:55 on Thursday 4th July 2013 (>300MW Aggregate Raw Off-Target across all Semi-Scheduled Units)
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...

Revenues for Wind Farms (and Solar Farms) in the NEM take a hit
A question over the weekend prompts this article, which follows from discussions to a Vestas-organised audience about revenue patterns and trends for Wind Farms in the NEM.
Extrapolating from the trend of ‘Aggregated Raw Off-Target’ results, to yield some clues to what the future might hold … and one challenge for NEM 2.0
Following on from Friday's article (which considered the AER Issues Paper) this article delves into more detail of those extremes of 'Aggregate Raw Off-Target' across all Semi-Scheduled units...
Striving to understand the underlying challenges with Semi-Scheduled generators (re AER Issues Paper)
Prompted by the recent AER Issues Paper (submissions on that due today - Friday 24th July) but also aware that I've not yet published some broader thoughts in...
