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 back-dated article about the AEMO's 2020 ISP
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.
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 that have been recorded over the...
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 response to the ESB's requests for...
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...
For several reasons I've updated my view of how daily aggregate Underlying Electricity Consumption has been trending across the NEM in this 'Year of COVID'.
The rule change that delayed the start of 5MS to 1st October 2021
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...
Here's an attempt to translate the concern underlying the AER Issues Paper into 'plain English' via the popular song.
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...
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 rooftop PV systems.
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 will happen on 15th July.
Prompted by what I'd seen in the (daily) periodic cycling of aggregate wind production recently, I took more of a look at what's been apparent over time.
It's not a surprise to me to see that someone (the AER in this case) has released an Issues Paper canvassing options for changing the way Semi-Scheduled generators interact with the dispatch process. Not...
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.
