A collation of articles here pertaining to energy literacy.
Belgium-based guest author Gilles Chaspierre looks at two major occasions where the NEM was suspended. In 2016, when physics outran the market; and in 2022 when the market outran the physics. He reads the pair as one lesson about what spot prices cannot see.
NEM demand tragic and occasional WattClarity guest author Allan O'Neil drills into an apparent discrepancy in AEMO's demand calculations following the 1 July 2026 transition of the Basslink interconnector from MNSP market participant to Regulated status.
Paul Austin explains how utility-scale batteries can use time block derivatives — selling Evening Peak and buying Midday contracts — to lock in intraday spreads and reduce exposure to spot prices, giving a useful baseline for budgeting, investment cases and revenue support scheme bids.
We thought it was worth separately collating these examples of how to answer the question ‘How many years of reference data are required to construct a robust model of the future?’.
The reasonable response is not to model the world as simpler than it is, but to confront its variability head-on: to treat stochastic inputs as stochastic, to plan for the distribution rather than its midpoint, and to build the margin of safety that resilience demands.
Dr Adrian Grantham from the AEMO has written this guest-authored post to provide an introduction into the functions of the organisation's Operational Forecasting team, the types of forecasts and other work they deliver, and the internal and external stakeholders they engage with.
Several conversations with customers (even as recently as this week) prompted this belated article about two documents from AEMO about dispatch timing - and particularly what happens within each dispatch interval.
In this guest-authored article by Endgame Economics, Oliver Nunn examines growing 'noise' in NEM spot prices — how increasingly frequent oscillations appear to have a structural, intraday pattern, what may be driving it, and why it matters for market behaviour and battery investment outcomes.
Nadali Mahmoudi from EPEC Group presents a short case study to show why network-outage modelling is essential for understanding revenue opportunities, curtailment risk and long-term investment decisions.
For short term reasons (related to the Nelson Review and the NEMDev conference) and longer-term reasons, we thought it was useful to post this as a stand-alone article now.
Josh Boegheim from Powerlink discusses the limitations of perfect foresight assumptions for system planning—and shares results from a recent study that simulated energy storage dispatch using deterministic and stochastic forecasting approaches.
5th article in a series, about the AEMO's ICF0002 initiative (and prior to tomorrow's EWCF Meeting) - to identify some questions and concerns.
As promised in prior articles, here's an illustration of (some of the) different Ramp Trajectories considered in Dispatch within the NEM.
4th article in a series, about the AEMO's ICF0002 initiative - clarifying 2 approaches might (possibly) be explored to resolve.
3rd article in a series, about the AEMO's ICF0002 initiative - and a possible 'solution' being considered (but for which we have concerns).
2nd article in a series, about the AEMO's ICF0002 initiative (re problems with the ~20 second lag in receipt of Dispatch Target).
1st article in a series, about the AEMO's ICF0002 initiative (specifically the content in EWCF meeting on 19th March 2024).
A third step in the 'Energy Literacy' journey in helping readers to understand the complexities within each and every Dispatch Interval.
A second step in the 'Energy Literacy' journey in helping readers to understand the complexities within each and every Dispatch Interval.
This article is a first step into exploring some of the complexities within three of the commonly used time-steps across the NEM.
