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.
Following up to AEMO’s recent Intermittent Generator forum, Marcelle looks at the challenges for wind and solar farms in providing consistently good plant availability information to AEMO and the value of transparency of this data.
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
David Leitch and Ben Willacy of ITK Services provide analysis of the NSW Government’s recently announced renewable energy plan.
A brief note to inform readers that the AEMC is fast-tracking consideration of the AER’s Proposed Rule Change on Semi-Scheduled assets … but also to reinforce our view that the challenge is MUCH broader than is being addressed here.
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.
