A collation of articles here pertaining to energy literacy.
We already noted this a few times recently, but we thought it would be worth separating out as its own article under the ‘Energy Literacy’ category, as it’s likely we’ll be referring back to it increasingly in future.
Read MoreWarwick Forster of Apogee Energy explains how retail and generator hedging works within a portfolio.
A timely reminder from the BOM of why ‘Apparent Temperature’ can be significantly higher than ‘Actual Temperature’ … such as across QLD on Saturday 27th Jan 2024 (and also Mon 22nd Jan 2024).
The third and final part of this series of articles from Greg Williams about opportunity costs in electricity markets – this time narrowing in on policy implications.
In the second part of this three part series, Greg Williams explains how fuel cost scarcity, inflexibilities, opportunity costs and other factors affects generator bids/offers.
Guest author, Greg Williams provides the first part of a three-parter about costs in the NEM. In part one here he explains modelling opportunity costs and the value of ‘the next best alternative’.
Because we’ll be referring back to it in future, we’ve lifted out Figure 8 from the MASS version 8 (p36/39) and included it here in this belated (and back-dated) article
It is indispensable to understand how the semi-scheduled unit availability gets produced to optimally manage the critical inputs and comprehend dispatch outcomes. This article explains the key inputs and processes, focusing on the dispatch timeframe.
Inertia is an important concept to understand as the technology mix in the NEM evolves during the energy transition. In this article, Jonathon Dyson talks about the importance of inertia and highlights an example of a specific incident where we observed relatively low levels of inertia in the NEM.
New guest author, Ryan Esplin progressively builds a more precise model of the NEMDE dispatch process to illustrate why the stylised ‘Merit Order’ bid stack model is increasingly not enough to explain dispatch and price outcomes in the NEM
Dan Lee explains why capacity factor could be becoming an increasingly less useful measure for comparing how different solar farms are performing and begins an exploration into some of the factors in play when trying to conduct more comprehensive analysis into generator performance.
Reposting a portion of an article we published some years ago, to help readers understand the difference between a MW and a MWh.
A short article about the AER’s publication (on 1st July 2022) of some updated information to help Semi-Scheduled generators understand their obligations.
To mark the end of the financial year, Dan Lee writes this explainer about MLFs and gives some examples of noticeable long-term MLF trends within the NEM.
Second (linked) article this evening, spelling out the two theories we’re aware of with respect to why some participants might have withdrawn capacity from the NEMDE dispatch/pricing run in June 2022 – leading to the AEMO Suspending the Market.
With Market Suspension (just) behind us, in this weekend article we take a look over the past 16 days to see how volumes offered to the market from the two types of plant have varied … and the prices they are offered at. The question is asked … why did those DUIDs withdraw capacity from the NEMDE dispatch and pricing run?
Marcelle explores how settlement prices are set and how dispatch is operating during the current market suspension.
Broader discussions about the ‘2022 Energy Crisis’, and the specific discussion this afternoon for the EUAA Electricity Committee prompted us to publish (in full) Key Observation #5 of 22 of our GenInsights21 report here today.
Limits on interconnectors play a key role in setting regional prices in the NEM. Marcelle finds a number of traps when interpreting the market data.
A question on Twitter from Benny Beatts (about dispatch of Origin’s Eraring unit 2 on Monday 30th May) illustrates why price setting is not as simple as adding up bids that are dispatched.
