Following the low levels of demand over the weekend (Sat 16th and Sun 17th Sept 2023) here’s a few quick notes.
Inertia is an important concept to understand as the technology mix in the NEM evolves during the energy transition. In this article, Jonathon Dyson talks about the importance of inertia and highlights an example of a specific incident where we observed relatively low levels of inertia in the NEM.
Drawing from GenInsights Quarterly Update for Q4 2022, and the next version of our ez2view software, we take a look at the *current* expectations for closure of Liddell Power Station (within weeks) and Eraring Power Station (in 2025). A segue into this week’s update to the ESOO, perhaps?
Three other reports released by AEMO on 1st December 2022 will also make for interesting reading.
On Sunday 6th November 2022 the NEMwide demand dropped below previous ‘lowest point’ records.
On Friday 14th October we saw a significant system event in Tasmania – with storms downing power links, leading to large (530MW) loss of load and trip of Basslink. In this article we take a first look at the sequence of events…
A deeper look at the frequency data (our own, and also from some others) reveals a number of other interesting things about what happened on Tuesday 25th May 2021 in Queensland.
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.
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…
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.
