What happens, when Supply ≠ Demand?
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.

The challenge of imperfect foresight: Storage operation in a highly renewable NEM
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.
Questions and concerns, about proposals to shift the ~23 second dead zone within the Dispatch Interval (ICF002)
5th article in a series, about the AEMO's ICF0002 initiative (and prior to tomorrow's EWCF Meeting) - to identify some questions and concerns.
There are actually several different ramp trajectories that are material to dispatch in the NEM
As promised in prior articles, here's an illustration of (some of the) different Ramp Trajectories considered in Dispatch within the NEM.
Why we have reservations about the possible solution AEMO has been considering (to date) in ICF002
4th article in a series, about the AEMO's ICF0002 initiative - clarifying 2 approaches might (possibly) be explored to resolve.
What’s the AEMO been considering, as a possible solution to the delayed receipt of Target?
3rd article in a series, about the AEMO's ICF0002 initiative - and a possible 'solution' being considered (but for which we have concerns).
What’s the problem(s) with dispatch targets arriving ~20 seconds into the Dispatch Interval?
2nd article in a series, about the AEMO's ICF0002 initiative (re problems with the ~20 second lag in receipt of Dispatch Target).
Challenges in ‘Time taken for Dispatch Targets to be made available to participants’ (ICF002)
1st article in a series, about the AEMO's ICF0002 initiative (specifically the content in EWCF meeting on 19th March 2024).
(A first step into the complexities of) the Dispatch Interval in the Real World
A third step in the 'Energy Literacy' journey in helping readers to understand the complexities within each and every Dispatch Interval.

Three of the common building blocks within the National Electricity Market
This article is a first step into exploring some of the complexities within three of the commonly used time-steps across the NEM.
About System Frequency
The NEM operates at a frequency of 50 hertz (Hz) which means the alternating current should cycle 50 times a second between positive and negative voltage.
NEMDE nightmares – parallel pathways and clashing constraints
Prompted by a question by a client in a training session for a new ez2view user, guest author Allan O'Neil has written 2,940 words to explain the price outcome in one particular dispatch interval...
A brief reminder about the complexity of measuring ‘Demand’ …
There’s essentially three measures of demand that are commonly talked about, and they are not really interchangeable.

An inter-regional interconnector refers to *the whole of* the transmission path between RRNs
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...
Managing an electricity portfolio in the NEM
Warwick Forster of Apogee Energy explains how retail and generator hedging works within a portfolio.
AEMO publishes update to ‘Guide to Mis-Pricing Information’ in conjunction with IESS
