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…
A quick additional look at activity Tue 28th Sept 2021 for Victoria Big Battery – as seen in ez2view with the benefit of ‘Next Day Public’ data.
A chart we threw together quickly at Beer O’Clock today (from the imminent release of the GSD2020) was worth sharing more broadly on WattClarity today…
Here’s an attempt to translate the concern underlying the AER Issues Paper into ‘plain English’ via the popular song.
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
1) The Demand Response Mechanism (better known as the Negawatt buyback mechanism)
2) The Bidding in Good Faith deliberation
3) The Requirement for Price-Responsive (large) Demand to bid into central dispatch
A quick look at a price spike that occurred Monday evening (4th August) in South Australia
Some worked examples of how several forms of Demand Response (including the proposed new Demand Response Mechanism) might impact wholesale prices, and participant positions.
Some quick observations about the patterns of volatility seen this week in Queensland
Some initial analysis looking into the question of whether the increased penetration of solar PV is increasing the variability of scheduled demand to the point that generators can exert more pressure on spot prices.
