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.
A short article today, highlighting the release of this Amperon report for AEMO looking at the way in which the performance of some Large Solar Farms in the NEM were affected by bushfire smoke through summer 2019-20.
A short article providing access to the much-talked-about report.
A quick look at this dispatch interval – as the 17th Case Study in the series looking at extreme results for Aggregate Raw Off-Target for all Semi-Scheduled DUIDs.
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]
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.
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?
Marcelle digs into the data to find out what the real issues are in the AER’s proposed rule change for semi-scheduled generators.
SwitchDin’s Joseph Kassouf examines the real-world challenges of coordinating control of rooftop solar inverters.
Yesterday evening (Tue 9th June 2020) saw an example of ‘dunkelflaute’ across the NEM. It’s a phenomenon we will see increasingly as the transition progresses, so it’s something we should be seeking to understand, and address, with real world solutions and not rose coloured glasses.
Ronald Brakels looks at the state of the home battery market and reflects on how past predictions of its evolution look in hindsight.
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 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
Tom Geiser, Senior Market Manager at Neoen, discusses the merits of proportional, relative control on the issue of small solar curtailment.
Analysis compiled to explore what the impact was of the unusual weather pattern (extensive cloud cover and cold temperatures) seen across a large part of Queensland on Saturday 23rd May 2020.
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.
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.
An article today providing links to the ‘Renewable Integration Study’ which the AEMO released today, and also to the headline media coverage I have seen on my quick scan this morning.
Guest author, Allan O’Neil, invests some time to explore a number of different aspects of Easter Saturday (11th April 2020), each noteworthy in their own right (including low demand, high percentage share renewables, negative prices and dynamic bidding)
Jonathon Dyson, Director of Greenview Strategic Consulting and co-developer of the Generator Statistical Digest 2019, uses insights from the GSD to illustrate the nuances of generation in the NEM as it goes through a major transition.
