This is the third of a short series of video snippets extracted from the 17th September 2020 presentation by Marcelle Gannon and Jonathon Dyson for the Clean Energy Council entitled ‘Maximising Profitability in the NEM’ for Wind Farms.
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.
This is the first of a short series of video snippets extracted from the 17th September 2020 presentation by Marcelle Gannon and Jonathon Dyson for the Clean Energy Council entitled ‘Maximising Profitability in the NEM’ for Wind Farms.
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.
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, Warwick Forster, provides an explanation of some of the common ways that retailers hedge their risk exposure in the National Electricity Market
Guest author Allan O’Neil provides this handy explainer on how generators’ contract positions affect their bidding decisions and can make negative spot prices pay off, at least in the short term. Very useful for those readers not actively involved in wholesale trading in helping to understand why some conspiracy theories might not match reality.
I’d rather not add to the number of conspiracy theories in circulation, but I wonder if there’s a conspiracy to make understanding our electricity system in general, and its reliability…
Guest author, Allan O’Neil, contributes to our series of articles explaining how prices are set the the NEM (as part of how dispatch works). In this article, Allan explains some of the details in the AEMO’s “Price Setter” file.
Guest presenter, Kate Summers, spoke at UoM Climate and Energy College on 15th August 2018, with the presentation recorded. Kate shares this today with WattClarity readers.
Highlighting the different approaches taken to cost/price based dispatch in an interconnected electricity system (or market).
Walking through 5 (much simplified) “Dispatch Intervals” to illustrate some starting principles of marginal price based dispatch arrangements, such as used in the National Electricity Market
Conversations in the week following my post about “Villain #4” (being the deficit in required Energy Literacy) prompted some analysis relating to Marginal Loss Factors
A year after I first spoke about “Villains” playing a role in the train wreck of our energy transition, I’ve finally found some time to post about Villain #4.
Following from a steady stream of questions we receive in relation to a range of our products (but in particular with respect to “the RenewEconomy Widget”) we’ve invested some time to put this post together to explain some of what we understand about electricity demand.
Following on from the Let’s Talk About FCAS post, the focus of this post is the business case and subsequent optimisation challenge for getting involved in FCAS, now that the technical performance components have been mostly addressed.
Understanding the difference between blackouts, generator trips and intermittent generation and how these events are managed.
This is a category of articles that have been accumulating on WattClarity for some time, aimed at helping to tame Villain #4, which is what we see as a growing…
Ancillary Services Matter! No longer just realm of electrical engineer or energy trading boffins, ancillary services (and particularly Frequency Control Ancillary Services or FCAS which will concentrate on today) have become front and centre in so many ways that barely a day goes by without market observers referring to grid stability, inertia or frequency management.
