Last Thursday (31st Aug 2023) the AEMO published the ESOO 2023, including forecasts of some possibility of unserved energy in Victoria and South Australia this coming summer 2023-24 (above the Interim Reliability Measure). Guest...
Kate Summers gave the keynote address for the "System and market design for a high renewables future" session at the CEC's Clean Energy Summit earlier this week. This article contains the full text of...
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...
Guest author, Allan O'Neil, publishes some analysis for WattClarity on price and generation mix changes apparent in the NEM coincident with (but not wholly caused by) the closure of the last remaining units at...
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...
Inspired by the recent article by Tristan Edis (who referenced the GSD2022 in analysis of curtailment of some wind and solar farms), Allan O'Neil follows on with more analysis of the two main types...
Tristan Edis from Green Energy Markets takes a deep dive into generator performance across the NEM. He provides his take on which wind and solar farms have outperformed and underperformed, through the recent renewable...
Tom Geiser argues against time-stamped Renewable Energy Certificates - and how the concept could impact trade, accuracy, market signals and other factors.
From 16th March 2023 the infamous 'x5 constraint' has been split into two. We quickly showed previously that the design of the Left Hand Side (LHS) does not vary. In today's article, valued guest...
Following recent online discussions, Bruce Miller has produced this in-depth analysis of frequency behavior in th NEM.
Allan O'Neil digs through historic FCAS enablement and utilisation levels to examine whether there is an increasing trend in recent years.
Nick Bartels of Greenview Strategic Consulting uses the price energy harvest metric from our GSD2022 data extract to examine the recent performance of each fuel type within the NEM.
Allan O'Neil provides an explainer about how small deviations in supply and demand are managed in the NEM, in order to help us understand the apparent swings in frequency that we noted in QLD...
David Leitch of ITK Services provides his top insights from the GSD2022, which he has used to look into generation mix, constraints and firming.
Guest author, Allan O'Neil, takes the release of the GSD2022 as an opportunity to take a look at the past 10 years of performance of the four-unit Liddell Power Station (one unit closed in...
UQ's Richard Bean and Neil Horrocks discuss a project they are involved with that would enable network operators to see household voltage and current data in real time.
James Martin from SwitchDin, provides an overview of the state of distributed energy management, and how it relates to last week's events in SA.
Ant Sharwood of Weatherzone provides some insights into the intensity of last weekend's thunderstorms in South Australia, which had severe impacts on the state's transmission network.
A weekend of prolific thunderstorms had a significant impact on the NEM. Ben Domensino of Weatherzone reports on the 4.2 million+ lightning strikes that were detected across the country on Saturday and Sunday.
Kate Summers gave this speech about the 'paralysis by analysis' currently occurring in the energy industry at Melbourne's All-Energy Australia Conference on Wednesday 26th of October.
