An initial review of some (wholesale) supply-side factors contributing to the extreme price volatility (and Reserve Trader etc) that occurred in the first week of February 2022 in the QLD region of the NEM.
A short (and first) look at some of the market activity on a volatile evening in several regions - SA and VIC, and with QLD joining the fray a bit later.
A quick look at three price spikes seen late afternoon in QLD on Monday 4th October 2021.
Following several different warnings of high temperatures forecast for the lead-in to Tuesday 26th January 2021 (whatever you want to call that day) I've taken a quick look at what it's currently forecast to mean for the NEM...
Today (Wed 13th Jan 2021) a high temperature alert published by AEMO for the Dalby area in southern QLD prompted a quick look at what the GSD2020 shows, in terms of high-temperature limitations of plant around the Dalby area.
As we wind down for Christmas, recapping some developments (in Nov and Dec 2020) about high temperature limitations on generation technology across the NEM.
It's not officially summer, yet - but it sure seems like it is across QLD and NSW. High temperatures drive some prices spiking up to the Market Price Cap in both ENERGY and some FCAS commodities as well...
My participation in yesterday's session about ‘Energy Technology – performing under (heat) stress’, organised by the Australian Institute of Energy, was an opportunity to reflect on what I saw as the Four Headline Events that gave example to a great many challenges we will have...
In the midst of winter, it would be easier to forget the stresses that the NEM encountered over the prior summer 2019-20. Thankfully, the Australian Institute of Energy has arranged for this discussion for next Friday 17th July.
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.
In her first article for WattClarity, Marcelle looks at questions raised in the recent summer on the forecasting of performance at high temperatures of wind and solar generators, and asks how AEMO and industry can work together to improve this.
Summer 2019-20 is not yet done, but already we have seen some extremes in temperature in different places - which have led to different concerns. Today I use the GRC2018 and GSD2019 to take a look at what the implications for this actually are.
Considering the extraordinary weather, bushfires, and a couple of large Victorian generators still not back from long term repairs, last week was probably less eventful for the NEM than might have been expected, but it certainly wasn’t incident-free. A very industrious Paul McArdle somehow found...
In what seems (to me) to be an extraordinary measure, AEMO speaks directly to the operators of Wind and Solar assets in the NEM, asking them to update the AEMO on the high-temperature limitations of their plant. How did it come to this?...
A first look back at yesterday (Friday 20th December 2019) in the Victorian region - where we saw extreme temperatures, high demand across VIC and SA and (perhaps because of high temperatures) a large discrepancy open up between forecast Wind Availability and actual. This would...
Took 2-3 times longer than planned (as there were a few different interesting observations that came out) but here is our initial - and perhaps only! - review of what happened in South Australia on Thursday 19th December 2019 (i.e. yesterday).
Returning to the challenge posed to readers in April 2019, to guess (or analytically determine!) which of the hundreds of units operating in the NEM showed such a severe limitation in output at high temperatures. It's not what most people thought it was - far...
We're taking a much, much deeper dive into generator performance at high temperatures (for all DUIDs operational across the NEM) to see how each one of them, individually, is affected by high temperatures. Guess which one this "mystery DUID" is and we'd look forward to...
An AEMO Market Notice about "Generator Recall" for Friday's forecast hot weather in South Australia and Victoria prompts a quick look at what's changed in the forecast that would prompt this action.
The first day of scorching summer temperatures for the year has been matched with elevated electricity prices in New South Wales, Victoria and South Australia for most of the day. Queensland and Tasmania experienced small patches of high prices yet prices remained elevated for the...
