Supply side price drivers in the NEM
Ben Willacy of ITK Services examines the GSD2020 and seeks to highlight what the report can tell us about supply side price drivers in the NEM
Areas of deeper analysis
Transition Fooled?
Through the lens of the GSD2020, Allan O’Neil looks at the much-discussed role of gas-fired generation in the ‘energy transition’ of the NEM’s generation sector
The Generator Statistical Digest 2020 (GSD2020) is released
From Monday 1st Feb 2021 the (720-page) Generator Statistical Digest 2020 is more broadly available – here’s some of what’s in it, and how you can access. Those dozens of clients who had submitted earlier pre-orders were provided early access on Friday 29th Jan 2021.
Prior to the wider release of the GSD2020 … here’s a 10-year trend of bidding behaviour
A chart we threw together quickly at Beer O’Clock today (from the imminent release of the GSD2020) was worth sharing more broadly on WattClarity today…
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.
Maximising the benefit of renewables with an intelligent energy management system
Following a presentation to the EESA in September, Dr Robert May and Ashley Nicholls from SA Water have written a case study detailing the sophisticated energy management system that they have developed over the past 7 years.
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.
Wind and solar transactions: What to buy in the new-year sales
David Leitch & Ben Willacy of ITK Services provide an overview of the wind and solar assets in the NEM that are currently up for sale
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.
NSW renewable energy plan seals death warrant for six gigawatts of coal
David Leitch and Ben Willacy of ITK Services provide analysis of the NSW Government’s recently announced renewable energy plan.
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 to fill in some background, provide…
Does the NEM need to be redesigned?
Guest author Stephen Wilson chaired an ‘ESIG Down Under’ conference webinar on ‘Designing the Energy Markets of the Future’. Whilst introducing the session, Stephen presented a diagram that helped to clarify the combination of different time horizons that need to be considered in holistically describing ‘the Market’. It will be of interest to WattClarity readers.
Some are waking up to the shortcomings of current methods of support for ‘Anytime/Anywhere Energy’
A couple glimmers of hope spotted recently, that there might be some (belated) awareness that the current methods of support for ‘anytime/anywhere energy’ are not scalable, or sustainable.
Which state pays for interconnectors?
Ben Skinner from the Australian Energy Council examines how transmission is currently funded in the NEM.
‘Maximising profitability in the NEM’ for Wind Farms
Short note to follow presentation by Marcelle Gannon and Jonathon Dyson on Thursday 17th Sept 2020 to an audience organised by Clean Energy Council (CEC).
Seasonality and deep storage in a highly decarbonized NEM
David Leitch of ITK Services examines the seasonal effects of Variable Renewable Energy (VRE) and some underlying challenges in this energy transition [this article is based on presentation at ‘Smart Energy Virtual’ on Wed 9th Sept 2020]
Diving deeper (part 2), about low demands on Saturday 29th August 2020
Prompted, in part, by yesterday’s record low for Victorian demand, today I have finished off my earlier review of what happened on Saturday 29th August (8 days earlier) when demand levels also dropped in VIC, and right across the NEM.
Revenues for Wind Farms (and Solar Farms) in the NEM take a hit
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.
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 past 10 years. There’s a clear clustering of cases in 2019 – what does it mean?
