The AEMC recently published a draft determination on Primary Frequency Response – proposing it remain mandatory, and to introduce big changes to the causer-pays process, including payments for good performance.
Today (Mon 27th Sept) we were alerted to this Virtual Information Session on Wednesday 29th September that some of our readers will be interested in (Enabling FCAS at Musselroe Wind Farm)
A rainy Saturday morning reminds us the price volatility for Q2 in QLD has not totally gone away … with elevated prices for ENERGY and also Contingency FCAS (Raise 6 second and Raise 60 second).
High Contingency FCAS prices (Raise 6 second) in response to what’s happened at Callide Power Station drove the Cumulative Price to (6 times) the Cumulative Price Threshold. Administered Pricing began Saturday evening for QLD.
Just under 3 weeks ago (on 22nd April 2021) the AEMC published a draft determination that would establish ‘Fast Frequency Response’ as an additional (i.e. 9th and 10th) FCAS service in the NEM. We take a brief look.
Guest author, Carl Daley, investigates why big batteries weren’t able to fully capitalise on extreme spot prices in SA on Friday 12th March.
David Leitch highlights some themes that stuck out to him as he read through this year’s edition of the Generator Statistical Digest – including a look at how batteries are dominating the FCAS market, some surprises with capacity factor, and other things
This is the fourth of a short series of video snippets extracted from the 17th September 2020 presentation by Marcelle Gannon and Jonathon Dyson for the Clean Energy Council entitled ‘Maximising Profitability in the NEM’ for Wind Farms.
Paul McArdle recently drew my attention to a short Twitter thread started by David Osmond on the arcane topic of NEM system frequency behaviour: At Paul’s invitation I’ve dived further into this issue to fill in some background, provide…
In a sneak preview of part of next Thursday’s Clean Energy Council webinar, Marcelle compares the spot revenue performance of wind farms across the NEM.
The University of Queensland’s project team that was involved with the installation and operations of their 1.1MW Tesla battery presented a webinar and exhaustive Q&A on the first results of the project.
Guest author, Andrew Wilson, presents a case study of the performance and results from the University of Queensland’s 1.1MW Tesla Powerpack system during Q1 2020.
Another islanding event separated the SA region from the rest of the NEM yesterday (Monday, 2nd of March). Allan O’Neil investigates what happened before the event and possible causes.
Jonathon Dyson of Greenview Strategic Consulting uses the Generator Statistical Digest to highlight FCAS revenue results, contingency recovery and regulation costs for 2019, and help explain why it is critical for us all to understand FCAS.
Guest author, Allan O’Neil, takes a look at what’s happened in the (islanded) market for FCAS services in South Australia over the past two weeks with Heywood out of service. He notes:
“generators in SA as a group would have paid out roughly twice in contingency raise FCAS costs what they earned from selling energy”
Guest author, Allan O’Neil, takes a look, via the GSD2019 (released today), at the four different headwinds facing solar farm developers and operators operating in the NEM.
Guest Author, Warwick Forster, looks at designing a combined solar & storage business model for the NEM
Guest author (and power system control specialist), Kate Summers, looks at what’s changed since she published a paper on frequency control in the NEM back in January 2017.
The multi-region islanding event on Saturday 25th August was a very rare event – perhaps the only one’s that occurred in the history of the NEM. It has generated plenty of questions – and driven our analysis further. We share some more observations here, and keenly await the draft AEMO report.
Guest presenter, Kate Summers, spoke at UoM Climate and Energy College on 15th August 2018, with the presentation recorded. Kate shares this today with WattClarity readers.
