More time has elapsed since ‘Part 3’ on 24th March – today I’m posting a shorter piece (Part 4) that explains how RHS of the ‘Q>>NIL_CLWU_RGLC’ constraint equation drove down output and led to the price spike on Sunday 24th January 2021.
It’s taken a while to find the time – but today I’m posting this next analytical piece (Part 3) that seeks to understand what happened on Sunday 24th January 2021 with the NEM-wide SCADA Failure, which contributed to the price spike that occurred in QLD by virtue of what it did to the ‘Q>>NIL_CLWU_RGLC’ constraint equation.
A short article this afternoon to link through to the Preliminary Report published by the AEMO, looking into what happened in South Australia last Friday (12th March 2021).
A shorter article – thinking more about the future, prompted by one of the factors that contributed to the price volatility seen in South Australia on Friday 12th March 2021

As promised in the Intermittent Generation Forum late in 2020, the AEMO has released an important Handbook for operators of Semi-Scheduled (wind and solar) assets.
Quite a synergistic coincidence today that, at the same time as we are finalizing the release of the GSD2020, we see the AEMO publishes its Quarterly Energy Dynamics for Q4 2020.
A week ago (Thursday 21st Jan 2021) we received an email from AEMO following the publication of Draft Guidelines for the Wholesale Demand Response Mechanism. We share some thoughts here today.
Following up to AEMO’s recent Intermittent Generator forum, Marcelle looks at the challenges for wind and solar farms in providing consistently good plant availability information to AEMO and the value of transparency of this data.
This is the second 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.
On Thursday 22nd October, the AEMO also released a short document titled ‘Operational management of low demand in South Australia’.
Guest author, Allan O’Neil, takes a look at the AEMO’s 2020 ESOO to unpick the reason for the differences in outlook (and the sensationalised news headlines) compared to 2019 ESOO.
AEMO also published something else today which (whilst not as publicised as the ESOO) will be of keen interest to many stakeholders in South Australia…
This is the 10th Case Study in a series working through 98 discrete dispatch intervals of extreme Aggregate Raw Off-Target for Semi-Scheduled events. This Case Study looks at only 1 of 5 occasions of extreme collective OVER-performance.
This morning the AEMO have called for expressions of interest for the ‘Unscheduled Short-Notice RERT’ for summer 2020-21.
There’s much to consider in today’s publication from the AEMO – which looks in detail at the many challenges they faced through summer 2019-20.
Curtailment seems like a simple concept, until you look closely at the details. In this article, Marcelle looks at how to estimate curtailment at wind and solar farms and explores some of the traps.
Tom Geiser, Senior Market Manager at Neoen, discusses the merits of proportional, relative control on the issue of small solar curtailment.
Recent invitations (from COAG Energy Council and AEMO) prompt some further analysis of the data set assembled for the GSD2019 in order to understand more about one of the challenges in balancing Supply and Demand in the NEM 2.0 world.
