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 past 10 years. There’s a clear clustering of cases in 2019 – what does it mean?
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 input into their Discussion Paper on the Two Sided Market concept, I’ve posted some further thoughts. These have been informed by a longitudinal analysis of Aggregate ‘Raw Off-target’ values across all Semi-Scheduled plant.
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 that gave example to a great many challenges we will have to grapple with as this energy (and climate) transition gathers pace.
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 ended. Some stakeholders clearly taken by surprise. Analysis includes the SWIS in Western Australia
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 next Friday 17th July.
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 a surprise, as our prior analysis suggests the current approach is not sustainable or scalable.
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 where output has dropped down near zero.
My understanding is that the AEMC’s Final Rule relating to the push to implement a ‘Negawatt Dispatch Mechanism’ will be released in the morning. I wonder what the implications will actually turn out to be…
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 we should be seeking to understand, and address, with real world solutions and not rose coloured glasses.
Yesterday I received a call from the people at PV Magazine who were preparing for the ‘Virtual Roundtables Europe 2020’ event on this week in Germany – i.e. Tuesday evening (now!) and Wednesday evening ‘NEM time’. I’m told the event…
A quick look at the two units tripping at 13:33 on Sunday 7th June 2020, and some earlier operational problems the day before (perhaps unrelated).
A brief note about the (also short) notice from the AER relating to two rule change proposals which it has been asked to propose by the COAG Energy Council
