AEMO publishes Handbook for Wind and Solar Generators
As promised in the Intermittent Generation Forum late in 2020, the AEMO has released an important Handbook for operators of Semi-Scheduled (wind and solar) assets.
General Reform Initiatives
A catalog of some more general reform initiatives … which perhaps have not gone so far as to be (or are too broad to be) encapsulated in Rule Change initiatives.
Increasing the transparency and correctness of intermittent generation availability information to AEMO
Following up to AEMO's recent Intermittent Generator forum, Marcelle looks at the challenges for wind and solar farms in providing consistently good plant availability information to AEMO and the value of transparency of this...
What’s “Primary Frequency Response” and why does it matter anyway?
Paul McArdle recently drew my attention to a short Twitter thread started by David Osmond on the arcane topic of NEM system frequency behaviour: At Paul’s invitation I’ve dived further into this issue...
AEMC proceeds to fast-track consideration of the AER’s semi-scheduled generator dispatch obligations rule change
A brief note to inform readers that the AEMC is fast-tracking consideration of the AER's Proposed Rule Change on Semi-Scheduled assets ... but also to reinforce our view that the challenge is MUCH broader...
AER releases proposed rule change for Semi-Scheduled generators and dispatch instructions
Following the consultation process conducted by the AER (stemming from their Issues Paper 3 months ago) the AER has today submitted a rule change request to the AEMC relating to Semi-Scheduled generation.
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 that have been recorded over the...
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 response to the ESB's requests for...
Semi-scheduled generation–what are the real issues?
Marcelle digs into the data to find out what the real issues are in the AER's proposed rule change for semi-scheduled generators.
‘Too Low for Zero’ as a parable for the AER Issues Paper?
Here's an attempt to translate the concern underlying the AER Issues Paper into 'plain English' via the popular song.
The rise of the ‘Negawatt Factory’?
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...
AER to develop two Rule Change proposals about Semi-Scheduled generation
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
Balancing Supply and Demand …. in the fast approaching ‘NEM 2.0’ world
Recent invitations (from COAG Energy Council and AEMO) prompt some further analysis of the data set assembled for the GSD2019 in order to understand more about one of the challenges in balancing Supply and...
Review of extremes in ‘Raw Off Target’ performance through 2019, with the Generator Statistical Digest 2019
Using the (hot off the press) Generator Statistical Digest 2019, we take a look across all 304 DUIDs to see how they performed through calendar 2019 in terms of large excesses in 'Raw Off-Target'...
Almost three years on – reflections on Frequency Control in the NEM
Guest author (and power system control specialist), Kate Summers, looks at what's changed since she published a paper on frequency control in the NEM back in January 2017.
All aboard the Negawatt Express … but where are we really headed?
Better late than never (perhaps?) today I post a few thoughts about the AEMC's proposed draft rule change for the incorporation of NegaWatts into centralized dispatch.
Some thoughts about Demand Response, in parallel with AEMC deliberations
A collection of thoughts that have been bumping around in my head for some time about the latest push by various parties to facilitate a broader range of demand response in the NEM, and...
Fast Frequency Service – Treating the symptom not the cause?
The National Electricity Market (NEM) is designed to operate at 50 Hz. Frequency deviation occurs when generation and load are mismatched. It is important in a lightly meshed and long network such as the...
