Returning for the second day of CEC QCES in the 'Long Duration Energy Storage' Oliver Nunn shared more insights from the Endgame modelling.
Flagging two charts that Rimu talked through to sum up some of the observations he made about some modelled results for some (unstated) year late in the next decade.
About 4 weeks ago the 2025 ESOO was released. In this article we highlight 3 x 2 different ways this might be viewed - and note some other dimensions not considered.

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 to 2022).
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'.
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.
It's Friday 15th December 2023 and the AEMO has published its draft of the 2024 ISP, in time for everyone's Christmas reading list
