As alluded to in several recent articles, we have underway a process for updating the ~180 page analytical component included in the Generator Report Card 2018 (released 23 months ago now). We are targeting a release of ‘Generator Insights 2021’ in Q3 2021, and would invite your pre-order.
Over 2,000 MW – or around 55% – of South Australia’s firm supply capacity was unavailable last Friday evening (March 12, 2021), along with virtually all of its large-scale renewable supply (a further 1,800 MW or so) but the lights…
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
Two initial thoughts, following EnergyAustralia’s announcement that they will close Yallourn Power Station four years earlier than initially planned (mid-2028).
David Leitch of ITK Services examines how electricity is losing its share of energy consumption in Australia, while also looking at the main drivers behind lower electricity demand this Summer compared to the previous year.
Watching what’s unfolded in Texas over the past 24 hours has been rather disconcerting … but also prompted questions about the broader energy transition. Here are some thoughts.
Wednesday 13th January 2021 was a busy day in the NEM, with a couple of different events occurring. In this article we explore a sudden and unexpected drop in output across both rooftop PV and large-scale solar in South Australia that delivered both price spikes, and also broader questions about emerging challenges for the grid (and market).
Following a week where several days saw price volatility in NSW (with this being so extreme that Reserve Trader was triggered on Thursday 17th December) we’ve taken a look at the comparative performance of coal units across the NEM (and particularly in NSW) compared to prior years.
Records continue to tumble in the off-season, with the rise of rooftop PV. Both South Australia and Whole-of-NEM hit new low points Sun 11th October 2020.
Only 52 days after I initially envisaged being able to have this article published, a couple things today have prompted me to post this drain-dump of concerns that have been jangling around in my head – related to possible risks that COVID might pose in the NEM.
This 16th Case Study in a series covers the first ‘extreme event’ into 2019 where there was an aggregate under-performance (compared to Target) across all Semi-Scheduled plant totaling greater than 300MW.
Have not checked thoroughly, but a quick scan suggests that the low point for Victorian Scheduled Demand at 13:05 today was a new record for minimum (daytime) demand. If it is, this would be an uncanny coincidence given …
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 morning the AEMO have called for expressions of interest for the ‘Unscheduled Short-Notice RERT’ for summer 2020-21.
An article today providing links to the ‘Renewable Integration Study’ which the AEMO released today, and also to the headline media coverage I have seen on my quick scan this morning.
… because the evidence currently suggests that this is just not the case (in this article I explore and explain further)
Guest author, Allan O’Neil tries to piece together further detail of what is intended with the apparent tightening of the Reliability Standard (which has sat at 0.002% USE for many years).
A back-dated article, looking back at the two ERM rule change requests which, when passed by the AEMC, had great effect in expanding transparency in the NEM in relation to generator availabilities from 20th August 2020.
Perhaps missed amongst all the bushfire-related action in the NEM, the SA Minister for Energy last week initiated the Retailer Reliability Obligation. Guest author Allan O’Neil tries to come to grips with what this means, and what happens next?
Guest author, Allan O’Neil, provides us an update today on what we can see about summer 2019-20 (in the physical market, and the financial market), now that it is only just around the corner.
