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.Read More
Areas of deeper analysis
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.
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
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.
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.
David Leitch and Ben Willacy of ITK Services provide analysis of the NSW Government’s recently announced renewable energy plan.
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…
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.
Ben Skinner from the Australian Energy Council examines how transmission is currently funded in the NEM.
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).
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]
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.
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.
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.
Ronald Brakels looks at the state of the home battery market and reflects on how past predictions of its evolution look in hindsight.
Yesterday I received a call from the people at PV Magazine who were preparing for the ‘Virtual Roundtables Europe 2020’ event on this week in Germany – i.e. Tuesday evening…
Just over 4 months have passed since the release of the Generator Statistical Digest 2019. We take a look back at some of the compliments and comments we’ve received and seen from a variety of people who have accessed their copy of the GSD2019.
This is the 3rd of 4 Case Studies to follow on from the main article (summarising results across 105,120 dispatch intervals through 2019 for ‘all Coal’ and ‘all Wind’ groupings). In this case, let’s look at the ‘worst’ case, in aggregate, where wind units under-performed compared to dispatch targets.
