Last week’s notable under-frequency load shedding in Great Britain following what appears to be the loss of two generation units in quick succession prompts me to publish some of the analysis of aggregate levels of inertia supplied by synchronous generators in South Australia as part of the Generator Report Card.Read More
Coincidentally this week it seems to me that we’re facing storm warnings on two different fronts – one literal (and much easier to prepare for), whilst the other one is metaphorical and operates at several different levels (and is much, much more difficult to manage).
Two quick notes about what happened in Victoria on Friday 25th January 2019 following conversations with a number of people.
Back at work this week and (with curiosity getting the better of me) I have another look at what happened last Thursday and Friday in the South Australian and Victorian regions of the NEM.
A first look at some of the action seen in the southern parts of the NEM on Thursday 24th January 2019 as a result of the latest crazy heatwave that has afflicted central Australia – particularly affecting electricity supply and demand in South Australia and Victoria
A short post, prior to further analysis next week, to notify readers that Reserve Trader has been dispatched today.
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.
Following on from Saturday’s islanding event, we use our current interest in AEMO’s 4-second SCADA data to prove a little more…
Both the QNI and the Heywood interconnectors tripped around the same time on Saturday 25th August 2018 (not apparent at this time which one was first, and why), leading to both QLD and SA regions being separately islanded from the rest of the mainland NEM. This also contributed to over 1,000MW of load shedding in NSW and VIC, and presumably some frequency excursions in QLD and SA.
A listing of key reports and analysis into the SA blackout of 28th September 2016.
The South Australian Blackout of 28th September 2016 is not as simple as it looks.
Wind speeds up during the blackout of September 28th in South Australia
First attempt to try to piece together events leading up to the blackout in South Australia on Wed 28th September 2016
Power’s out across South Australia on the afternoon of Wednesday 28th September
I have been asked a couple of times recently, by new entrants to the NEM, about the impact of the drought in 2007 on generation levels around the NEM. This…
Some further analysis of the MT PASA and ST PASA forecasts for other regions of the NEM (SA, TAS, NSW and QLD) for the day of 29th January 2009 – when a new record NEM-wide demand was established.
A quick look at how useful NEMMCO’s PASA forecasts were, prior to the record levels of demand seen across the NEM on Thursday 29th January 2009
We saw a massive new peak for NEM-Wide demand set on 29th January 2009, which surprised many (including us).
We return to that data and, by comparing with the previous 10 summers, see whether it should have been entirely unexpected.
A Market Event Report has been published on the NEMMCO website discussing the market outcomes of the high energy prices in the New South Wales and Queensland regions on Friday, 31 October 2008.
This is just a short note to reflect on the fact that the NEM will be 10 years old tomorrow. All together now, “Happy Birthday to you…”
