Patricia Boyce’ challenging question coincided with the low point of cyclic wind output across the NEM this afternoon, and prompted some thinking…
low wind production
Yesterday evening (Tue 9th June 2020) saw an example of ‘dunkelflaute’ across the NEM. It’s a phenomenon we will see increasingly as the transition progresses, so it’s something we should be seeking to understand, and address, with real world solutions and not rose coloured glasses.
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!)
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?…
One of our guest authors, Allan O’Neil, takes a closer look at what happened in the South Australian region of the NEM on Monday 9th July 2018
Some brief analysis of today’s price volatility seen in the South Australian region of the NEM
The start of some analysis that helps to identify the variety of factors that combined to give a shaky balance between supply and demand in NSW last week.
An unexpected network outage in the south-east of South Australia restricts supplies from Victoria at a time of low wind supply in South Australia and results in the dispatch price spiking to $14,200/MWh from 11:30 and oscillating for the afternoon
From one extreme (perhaps lowest ever in June 2017, on like-for-like) to the other (new record production) in the space of just one month for aggregate wind in South Australia
Some back-of-the-envelope calculations being a starting point to help me understand how much real contribution electric vehicles might make in feeding back into the grid when intermittent generation is absent.
Demand surges in Victoria and South Australia on the back of blistering heat, dragging prices out of their long-term slumber as a result.
Some quick notes today, on day #2 of the Carbon Tax, prompted by some prices that jumped all around the place (not so much due to carbon, though).
