What’s the 2024 ESOO assume, in terms of coal unit performance?
In this article we explore the 2024 ESOO, and linked documents, in terms of what's assumed for coal unit EFOR - and why, in the light of recent improvements in coal unit performance (compared...
A precis of the ‘Exploring Wind Diversity’ analysis completed in Appendix 27 of GenInsights21
Almost 2.5 years since we released GenInsights21, today we're publishing this article that contains a precis of the analysis included as Appendix 27 under the title 'Exploring Wind Diversity'.
Optimising a highly renewable NEM from scratch, Part 2
In Part 2 of their modelling and analysis project, David Leitch and Paul Bandarian discuss the modelled results of their sharpe ratio-maximised VRE system, including additional considerations regarding transmission.

This morning I was fortunate to listen into an ESIG Webinar with respect to their report 'Weather Dataset Needs for Planning and Analyzing Modern Power Systems'
Bigger or better: Are newer wind farms outperforming older ones?
Dan Lee looks at twenty years of capacity factors for wind farms to see if they are improving in line with recent discussion and long-term modelling assumptions.
Here’s 7 Observations that jumped out to me in a first skim of the 2023 ESOO
Apart from a distraction early this morning, I've invested some hours today in review of the 2023 ESOO. Here's 7 initial observations that jumped out at me.
With the 2023 ESOO report, different views about which USE figure should the AEMO have led with?
Here's my view on whether Figure 2 should have preceded Figure 1 (with respect to projections of unserved energy ... USE) in the 2023 ESOO.
The 2023 ESOO report clarifies why the transmission model only includes ‘System Normal’ – and why it’s a simplification
One observation about the 2023 ESOO is that AEMO is has highlighted the set of constraints modelled is only 'System Normal'.
The 2023 ESOO modelling provides a more accurate real world depiction of Wind Farm limitations at high temperatures
One observation about the 2023 ESOO is that AEMO is now modelling (more accurately) the high temperature degradation on wind farm performance.

The VEPC paper ‘No longer lost in transmission’, and the AEMO response
An article today referencing the VEPC paper 'No longer lost in transmission' (about extended VNI-West, and the authors proposed alternative 'Plan B') and the AEMO's initial response.
How dispatch works … it’s much more than just a bid stack
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...
