detailed analysis
What does the future hold for Wind and Solar in the NEM – seen via GenInsights21?
Following from the release of GenInsights21, in this article we look at some of what that analytical publication can help us understand, in terms of how the changing market is impacting on the role that renewables will increasingly play in the NEM in the years to come.
How should the AER’s wholesale monitoring responsibilities change, to suit the changing market environment?
On Tuesday 21st December 2021 the AER requested the AEMC to consider changing the prescriptive requirements in the Rules for the AER to analyse particular types of market outcomes in particular ways, and instead provide the AER more flexibility in what its analysis covers.
David Leitch’s review of GenInsights21
Occasional guest author, David Leitch, grasped an opportunity for an early read of GenInsights21 – and shares some of his observations here with WattClarity readers.
The 28 x ‘Deep Dive’ Appendices included in GenInsights21
Last Wednesday (15th December) we released GenInsights21. In this article we provide a full list of the 28 Appendices included with the publication, and from which many of the Key Observations have been drawn.
GenInsights21 released, on Wednesday 15th December 2021
It’s Wednesday 15th December 2021 and we have released GenInsights21 (a deep dive exploration, asking what history can tell us of the challenges and requirements of the accelerating energy transition).
Full steam ahead, for completion of GenInsights21 (release delayed a short while)
Here’s the 6th Dec 2021 status update on your GenInsights21 release – we’ve completed (most of) the work for you, just need to wrap it all together by answering questions like ‘so what’s this all mean, when considered together?’.
Another ‘mystery DUID’ puzzle (from Forecast Convergence in GenInsights21)
A second ‘mystery DUID’ puzzle … perhaps more complex than the first … from GenInsights21, for those who like to be challenged in ways like these.
Discussion at AIE Brisbane on 2nd Dec 2021 – Early insights on Five Minute Settlement
Here’s the event details for the discussion scheduled for Thursday 2nd December 2021 about ‘Early insights from Five Minute Settlement’, thanks to AIE Brisbane.
Re-starting compilation of GenInsights21, for release December 2021
Following a period when it was placed on the back-burner, due to other priorities, we’ve now re-started the development process for GenInsights21 and would invite you to pre-order your copy.
AEMO releases Incident Report on 25th May 2021 event emanating from Callide C4
This morning (Fri 8th Oct) the AEMO has released its Incident Report into what happened on 25th May 2021, starting with problems at Callide C4.
Initial look at the latency of all rebids
Following from some analytical work performed in testing for Five Minute Settlement, here’s a view of latency of rebids (all DUIDs, all commodities) in recent months that prompts a number of questions…
Is the predictability of day-ahead demand improving?
Day-ahead demand forecasts will be integral to any future ‘Ahead Market’. We take a look at the current state and accuracy trend of demand forecasts made 24 hours ahead as part of the broader piece of work to feed into GenInsights21.
Potential Tripwire #3 When is a load not a load?
A feature of the upcoming EMMS technical specification that distinguishes demand response units from scheduled loads could impact some users of NEM data, if left unmanaged.
Where’d the wind go, during the last week of April?
Over the week that has just passed we kept noticing production from wind farms across the NEM was fairly muted – so we’ve had a look at what it meant, in aggregate daily capacity factors. This is something we’re exploring much deeper in Generator Insights 2021…
Announcing development of ‘Generator Insights 2021’, and inviting your pre-order
As alluded to in several recent articles, we have underway a process for updating the ~180 page analytical component included in the Generator Report Card 2018 (released 23 months ago now). We are targeting a release of ‘Generator Insights 2021’ in Q3 2021, and would invite your pre-order.
AEMO releases ‘Quarterly Energy Dynamics’ for Q4 2020
Quite a synergistic coincidence today that, at the same time as we are finalizing the release of the GSD2020, we see the AEMO publishes its Quarterly Energy Dynamics for Q4 2020.
Cranking the handle, to produce the Generator Statistical Digest 2020
In the same week that the Energy Security Board publishes it’s ‘The Health of the NEM’ reports, looking from a top-down systems perspective, we crank the handle to produce the ‘Generator Statistical Digest 2020’ as a bottom-up 10-year review of the performance of all Scheduled, Semi-Scheduled and some Non-Scheduled generators and scheduled loads across the NEM that operated through some part of 2020.
Constraint Case Study Followup – Early outcomes of the new “X5 constraint”
On 25th November, guest author Allan O’Neil examined the ‘X5 Constraint’. Two weeks of operation have passed, so now Allan reviews some of what’s happened.
Case Study – How to interpret a new NEM constraint and guess what it might do
Given the great interest in the new ‘X5 constraint’, guest author, Allan O’Neil, has invested some time to pick the new constraint equation to understand (and then explain) what it is, how likely it will be to bind, and who is likely to be affected.
