A quick record of ‘equal hottest September day on record’ for Sydney … and its impact on electricity demand
One observation about the 2023 ESOO is that AEMO is now modelling (more accurately) the high temperature degradation on wind farm performance.
Looks like a new all-time record for Operational Demand in the QLD region early this evening, Friday 17th March 2023.
On Monday afternoon 6th March 2023 a late burst of summer in NSW has driven Market Demand above 13,000MW.
Could be a hot one in (Sydney and) NSW on Monday 6th March 2023 … with AEMO forecasting potential LOR2 low reserve condition.
On Thursday 23rd February, hot weather in SA drove ‘Market Demand’ to its highest level in just over 9 years, and delivered a bit of spot price volatility. We investigate….
A quick look at how Market Demand peaked on a hot Sunday afternoon/evening in QLD.
A short note about AEMO’s MN104622 … with a high temperature warning for Port Augusta for 26th December 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.
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 to grapple with as this energy (and climate) transition gathers pace.
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.
