A large collection of articles pertaining to the ongoing ‘Energy Transition’ in any of a number of ways.
Specific sub-categories relate to such things as Coal Closure, and other aspects of the transition.
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...
During early morning Monday 1st May prices spiked in the NSW quite unexpectedly. Guest author Allan O'Neil takes us into the complexities of the EMMS and NEMDE to help us understand the mechanics of...
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...
Liddell Unit 1 ramped down it's output to 0MW at roughly 10:30am this morning, signaling the full retirement of Liddell Power Station.
As many know, Liddell Unit 1 is slated to close today (the last of the 4 units), Friday 28th April. Unfortunately coincident with that, AEMO is forecasting LOR2 low reserve condition for the middle...
A short article to mark the closure of Liddell unit 2 on Wednesday evening, 26th April 2023.
A quick note to show the last dispatch interval of output from Lidell Unit 4, with the two remaining units slated to follow suit in the coming days.
A short article today (whilst in the midst of finalising GenInsights Quarterly Update for Q1 2023) presenting an overview of Aggregate Raw Off-Target (AggROT) for Semi-Scheduled units on Friday 3rd February 2023.
Latest data from AEMO (from Fri 14th April) suggests Liddell unit 4 might close a couple days later than when we'd looked in February.
We delve deeper into dispatch availability self-forecasts and the assessment process to further enhance our understanding of this important aspect, testing sensitivity to gate closure times and requirements on minimum intervals.
Around eight days till the scheduled closure of Liddell's next-to-close unit (and prompted by an article in the AFR), we take a quick look at how they've been bidding.
In the fourth instalment of this ongoing case study, Dan Lee maps the locations and contributions of the semi-scheduled units that contributed to the +861MW Aggregate Raw Off-Target that occurred on the afternoon of...
Given the significance of the event (Reserve Trader almost triggered on Thursday 16th March - 34 days till the closure of Liddell Unit 4) we're investing some time in exploring more detail of the...
In Part 3 of this Case Study, we look at the source of the Dispatch Interval Availability forecasts for these units at 17:05 on 27th October 2022 (i.e. Self-Forecast or something else, incl AWEFS/ASEFS).
In Part 2 of this Case Study, we look at those 15 x Semi-Scheduled units highlighted with large deviations (mostly under-performance) at 17:05 on 27th October 2022 in order to understand more.
In Part 1 of this Case Study, we start to look at the large collective under-performance across all Semi-Scheduled units (i.e. Wind and Large Solar) at 17:05 on 27th October 2022. More to come...
In today's article (a third snippet from GenInsights Quarterly Update for Q4 2022) we take a look at levels of large 'Aggregate Raw Off-Target' (i.e. large collective deviations away from Target), which continue to...
Here on this site, and also in real discussions in the offline world, we have been pondering this question for a number of years. For instance, it was pondered in Theme 13 (‘What’s the...
Another quick article today - this to record the rare use of coal in the UK on a cold evening with insufficient other supply.
