A large collection of articles pertaining to the ongoing ‘Energy Transition’ in any of a number of ways.
Specific sub-categories relate to such things as Coal Closure, and other aspects of the transition.
Patricia Boyce’ challenging question coincided with the low point of cyclic wind output across the NEM this afternoon, and prompted some thinking…
Patricia Boyce examines a chart that was included in the AEMO’s Renewable Integration Study, which depicted actual and modelled solar and wind generation output against underlying demand. She then looks at whether intermittent generators can achieve sufficient return and discusses the problems that still need to be solved.
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.
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.
A short article providing access to the much-talked-about report.
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.
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.
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.
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.
