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.
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…
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1st February 2020 (something that alarmed me, and resulted in AEMO directing a participant to make capacity – just withdrawn – available again).
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…
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.
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
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!)
A quick look (ahead of time) at what looks set to be a very high level of electricity demand right across the NEM tomorrow evening, Friday 31st January 2020. Just in time for the Australian Open semi-finals.
Today I managed to get about half-way (only!) through some analysis I wanted to do to ‘scratch that itch’ about what happened in the NSW Region on Thursday 23rd January – with LOR2 conditions necessitating RERT (Reserve Trader) in the NSW Region.
This afternoon saw the Queensland Scheduled Demand peak at 9,657MW – under 400MW off the all-time record set in February 2019.
Following yesterday’s dust storms, today’s rain (and hail) also sweep through NSW to dampen production from solar farms – small and large.
A brief (initial?) look at the impact of yesterday’s dust storm on the output of NSW large-scale solar farms – particularly Nyngan Solar Farm
All I have time to do today, looking into more detail of what happened today …. but note that the challenge is still unfolding.
A quick summary of what’s just happened this afternoon (15:10) with the separation of VIC-to-NSW interconnector due to bushfires that have been plaguing the NEM this summer…
A quick article with the unfolding situation this afternoon in Victoria – tight supply/demand balance, price spike to the Market Price Cap, and RERT negotiations ….
A short note looking at forecast for Victoria today, Monday 30th December (coincidentally as Loy Yang A2 came offline on Friday evening).
With the return of Mortlake unit 2 this week, we take a quick look at current forecasts for the week and quarter ahead in Victoria.
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…
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?…
