Collections of events that we see happening in the NEM, categorised in terms of the seasons in which they occur.
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...
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...
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...
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...
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...
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...
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...
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...
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.
Some quick reflections on a day that saw spot prices in QLD down below $0/MWh for most of the period seeing strong daylight hours, hence strong injections from...
During another week that showed signs of the challenges facing all generators (new and old) in relation to spot prices for energy, invitations were delivered for discussions that...
There's much to consider in today's publication from the AEMO - which looks in detail at the many challenges they faced through summer 2019-20.
A brief look at what's been happening at Bald Hills Wind Farm - over the 18 months since January 2019, but most particularly in the past couple weeks...
Yesterday evening (Tue 9th June 2020) saw an example of ‘dunkelflaute’ across the NEM. It's a phenomenon we will see increasingly as the transition progresses, so it's something...
