Cool change arrives in Melbourne early on Monday 25th January 2021, dampening high demand expectations
Forecasts was that it would be hot across Victoria, and demand would be high, through Monday 25th January 2021. But the cool change arrived early.

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…
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.
What’s up with the fleet of 16 x coal-fired units in NSW?
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.
Price volatility (third day in a row) … and Reserve Trader dispatched in NSW
Third day in a row we see volatility in NSW (and QLD) … and this afternoon AEMO contracts, and then dispatches, Reserve Trader in NSW
More price volatility in (QLD and) NSW on Wednesday 16th December 2020
Second day in a row the price spikes in the NSW region … higher and longer than yesterday. Low aggregate production from Wind and Large Solar across NSW today was clearly one other factor that contributed.
ESOO 2020 – What a difference a year makes
Guest author, Allan O’Neil, takes a look at the AEMO’s 2020 ESOO to unpick the reason for the differences in outlook (and the sensationalised news headlines) compared to 2019 ESOO.
AEMO releases its 2020 Electricity Statement of Opportunities (ESOO)
This morning (Thursday 27th August 2020) we saw the AEMO release the 2020 edition of the Electricity Statement of Opportunities.
AEMO tenders for Short-Notice RERT Panel for Summer 2020-21
This morning the AEMO have called for expressions of interest for the ‘Unscheduled Short-Notice RERT’ for summer 2020-21.
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 to grapple with as this energy (and climate) transition gathers pace.
‘Energy Technology – performing under (heat) stress’ – discussion on Friday 17th July 2020
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.
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.
Semi-scheduled Generation Availability Forecasts–how to improve?
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.
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.
Heat pushes QLD Scheduled Demand within 214MW of the all-time maximum level on 3rd February 2020
It feels like a lifetime ago, already, but I do vaguely remember that we released our Generator Statistical Digest 2019 last week, on Tuesday 28th January 2020. All the tasks that I had scheduled to follow on from that launch…
Out of the blue, another LOR2 – NSW region on Saturday 1st February 2020
With the benefit of more data available today, can piece together why there was the sudden drop into LOR2 territory on Saturday 1st February 2020 (something that alarmed me, and resulted in AEMO directing a participant to make capacity – just withdrawn – available again).
Hot weather and high demand continues, with actual LOR1 in NSW region at 13:55 on Saturday 1st February 2020
I’ve snuck into the office on Saturday to start the process of piecing together some of of the different aspects of what happened yesterday to follow on from Friday evening’s short article (this will take quite a while to do…
White knuckle ride across the NEM on Friday 31st January 2020 (extreme NEM-wide demand)
Today (Fri 31 January 2020) saw NEM-wide demand reach levels never seen before (excepting 29th January 2009). This was just the start of the white knuckle ride.
A further look at Thursday Jan 30th
Guest author, Allan O’Neil does a masterful job with limited time in reviewing some of the goings-on in the NEM (particularly VIC and SA) on Thursday 30th January 2020
Thursday 30th January 2020 sees demand reach 34,257MW and LOR2 notice issued for both VIC and SA
A brief overview of a stressful afternoon/evening in the NEM, where a confluence of events (heatwave-driven high demand, low wind, coal unit trip, etc…) drive LOR2 low reserve condition notice in both VIC and SA, and gear AEMO up to call on Reserve Trader (yet again!)
