Five days after Tuesday 13th February 2024 we have a bit of time to take this initial (top-down) look at bidding for ENERGY in the Victorian region on that day … with 27 Questions/Observations identified!
On Friday 29th September 2023 we look back at Kogan Creek via ‘Bids & Offers’ in ez2view over 20 days to see what’s visible, in terms of any impact of the current Industrial Action
Alerted by RenewEconomy on social media that Beryl Solar Farm was offline due to bushfires, I used ez2view to take a quick look.
Walking through some of the responses I can see in 19 of 67 Wind Farm units on Wednesday 10th August 2022 … when a software glitch delivered extreme contingency FCAS prices across all regions (though they were subsequently revised down).
Will need more time to think why Coopers Gap WF would bid in this way on Sunday evening with ‘Actual LOR2’ notices at play.
An initial review of some (wholesale) supply-side factors contributing to the extreme price volatility (and Reserve Trader etc) that occurred in the first week of February 2022 in the QLD region of the NEM.
This morning I’ve taken a quick look at market activity in South Australia on Thursday evening, 30th December 2021.
A short article (in the midst of GenInsights21 completion) more broadly sharing 2 good news stories from AEMO in the context of the NEMDE dispatch process.
A short article today, to share an image from the upcoming GenInsights21 release, and to pose some questions – about what’s been happening with the rise (and fall!) of bid volumes at Large Solar Farms in the NEM.
Following from some analytical work performed in testing for Five Minute Settlement, here’s a view of latency of rebids (all DUIDs, all commodities) in recent months that prompts a number of questions…

Guest author, Allan O’Neil, invests some time to explore a number of different aspects of Easter Saturday (11th April 2020), each noteworthy in their own right (including low demand, high percentage share renewables, negative prices and dynamic bidding)
Thursday 10th October 2019 presented another day of many negative price events in the QLD region. In this Case Study (prepared for dual purposes) we look at how one particular solar farm operated through this period – Ross River Solar Farm.
As part of the process of compilation of our Generator Report Card 2018, we’re delving into quite some detail into various aspects of generator bidding and re-bidding. Today I thought it might be useful to share some *very early and preliminary* observations that we’re starting to see when trending and categorising rebids.
Some ideas that I have been puzzling over – about the overlaps and contradictions between 3 rule changes under consideration at the AEMC currently
