‘Summer is coming!’ … Part 1
Over recent weeks we’ve seen a number of warnings about what’s in store for summer 2026-27 in the NEM, so we take a first look.
high temperature limitation on output
Here are some articles tagged with ‘high temperature limitation on output’.
For a broader introduction, you might like to read the article ‘Extreme temperature effects on generation supply technology’ from February 2000, as this helps to illustrate that almost all supply and delivery technologies are affected by high temperatures in various ways.
To what extent did high-temperature de-rating contribute to large under-performance across Semi-Scheduled Wind fleet on Tuesday 27th January 2026?
This is the 2nd of two articles today … this one specifically focused on Wind (i.e. the Semi-Scheduled units) and the aggregate Dispatch Error across all 288 dispatch intervals on Tuesday 27th January 2026.
Under-performance of Wind Farms increased during the recent heatwave
A conversation today amongst our broader cohort about the heatwave earlier this month had me scurrying to the ‘Trends Engine’ in ez2view to produce the following macro view of ‘Dispatch Error’ across the entire* Wind Farm fleet NEM-wide.
Further analysis (and more questions) about four VIC Wind Farms on Monday 16th December 2024
In this article, we're continuing to explore what happened to some Wind Farms in Victoria on Monday 16th December 2024 - which was a day of high temperatures, and on which many interesting things occurred. In this particular article, we focus on 4 x Wind...
Part 2 in a review of bidding, on Monday 16th December 2024 (a focus on VIC Wind Farms)
We’ve posted ‘A quick initial review of bids, for Monday 16th December 2024’ early in the morning of the following day. In this follow-on article, we focus specifically on Wind Farms in Victoria - using 'Bids & offers' widget in ez2view to peel one more...
A quick initial review of bids, for Monday 16th December 2024
Monday 16th December 2024 was an interesting day in the NEM for a number of reasons. So we’ll use the ‘Bids & Offers’ widget in ez2view to do this quick initial review and then, depending what we see, determine whether we want to invest further...
AEMO publishes ‘NEM Local Temperature Alerts for NSW, SA, VIC from 12 Dec 2024 to 16 Dec 2024’
Topical, given forecast load shedding for NSW on Monday 16th and Tuesday 17th December, is the latest high temperature alerts for large parts of the NEM on 14th, 15th and 16th December 2024.
Forecast temperature rising in Queensland for Thu 18th Jan 2024 (and Fri 19th and Mon 22nd)
A first article about forecast high temperatures (hence high demand, and also potentially LOR levels) for Queensland on Thursday 18th January 2024 ... and also Fri 19th and Mon 22nd.
The 2023 ESOO modelling provides a more accurate real world depiction of Wind Farm limitations at high temperatures
One observation about the 2023 ESOO is that AEMO is now modelling (more accurately) the high temperature degradation on wind farm performance.
‘NEM Local Temperature Alert’ for Port Augusta on Monday 26th December 2022
A short note about AEMO's MN104622 ... with a high temperature warning for Port Augusta for 26th December 2022.
Summary view of supply-side contributions in QLD during ‘heatwave week’ – particularly Tue 1st Feb 2022 and Wed 2nd Feb 2022
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.
High temperatures, and high demand, forecast for Monday 25th January 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...
NEM Local Temperature alert for Dalby (QLD) for Sat 16th Jan 2021 … an opportunity to check the draft GSD2020
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.
Temperature Alert!
As we wind down for Christmas, recapping some developments (in Nov and Dec 2020) about high temperature limitations on generation technology across the NEM.
Four headline challenges amongst a very busy summer 2019-20
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...
AEMO releases its ‘2019-20 NEM Summer Operations Review Report’
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.
Extreme temperature effects on generation supply technology
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.
AEMO speaks directly to Wind and Solar Farm operators – please alert us to temperature limitations on your assets
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?...
Which was that ‘mystery DUID’ that apparently ‘can’t stand the heat’*?
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...
