In a sneak preview of part of next Thursday’s Clean Energy Council webinar, Marcelle compares the spot revenue performance of wind farms across the NEM.
5-minute settlement – Why it makes such a difference to utility scale storage in Australia’s National Electricity Market
Guest author, Warwick Forster, examines the delayed but impending move to 5-minute settlement for the NEM and the potential effects on utility scale storage.
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?
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 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.
Marcelle digs into the data to find out what the real issues are in the AER’s proposed rule change for semi-scheduled generators.
Here’s an attempt to translate the concern underlying the AER Issues Paper into ‘plain English’ via the popular song.
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.
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.
SwitchDin’s Joseph Kassouf examines the real-world challenges of coordinating control of rooftop solar inverters.
Several stakeholders within the DER industry have come together to publish a best practice guide specifying the data required to enable aspects of the next iteration of our electricity network. Our guest author, Stefan Jarnason of Solar Analytics, writes about the need for real time DER data and explains aspects of the guide.
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…
Ronald Brakels looks at the state of the home battery market and reflects on how past predictions of its evolution look in hindsight.
The University of Queensland’s project team that was involved with the installation and operations of their 1.1MW Tesla battery presented a webinar and exhaustive Q&A on the first results of the project.
Curtailment seems like a simple concept, until you look closely at the details. In this article, Marcelle looks at how to estimate curtailment at wind and solar farms and explores some of the traps.
A few quick words, about the challenges inherent in assessing the benefits of diversity too superficially. It clearly does have some benefits, but it’s not a Magic Wand.
On Thursday 21st May, Marcelle Gannon and Jonathon Dyson jointly shared a large number of insights and tips to help those interested in developing and/or operating Large Solar Farms in the NEM maximise the value they receive. Useful also for those interested in Wind Farms (i.e. any Semi-Scheduled plant), and also hybrid operations using Batteries.
In a sneak preview from the “Maximising Value in the NEM” webinar this Thursday, Marcelle looks at the changing distribution of spot prices in QLD.
Guest author, Andrew Wilson, presents a case study of the performance and results from the University of Queensland’s 1.1MW Tesla Powerpack system during Q1 2020.
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 Demand in the NEM 2.0 world.
