Earlier LOR conditions forecast for SA this morning did not eventuate to an actual, but the region was hit with a short run of price spikes.

Dan Lee provides some exploratory calculations in order to estimate the total cost of maintaining electricity supply throughout a very turbulent June.
The market volatility on Wednesday 10th August 2022 turned out to be illusive. We review unit output by fuel type to study how different generator groups responded on the day (in aggregate) finding increases, decreases and patterns in between.
After many years in a row, we return (in the midst of the ‘2022 Energy Crisis’) to review the pricing patterns in the NEM and the WEM for Q2 2022.
A quick look at some of the factors of this morning’s price volatility in the QLD region.

Recent WDR activity on January 31 took advantage of the spicy Victorian wholesale energy prices that eventuated in the late afternoon and early evening under unusual circumstances.
Carl Daley of EnergyByte, examines recent energy and gas price volatility, leading to the conclusion that the May to July period in QLD and NSW has been the biggest shock to the spot market in history, and the forward price movements are rivalling the record setting year of 2007.
A short article marking (yet) another volatile evening in the NEM in this ‘elephant’ of a Q2 2021… now with some added challenges for gas-fired generation.
Carl Daley of EnergyByte examines the ramifications of the Callide Power Station outage and discusses the big losers and winners from the situation.
Third short article this evening, after it looks like we’ve escaped from a tight supply/demand balance (reasonably) unscathed.
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!)
Took 2-3 times longer than planned (as there were a few different interesting observations that came out) but here is our initial – and perhaps only! – review of what happened in South Australia on Thursday 19th December 2019 (i.e. yesterday).
Back at work this week and (with curiosity getting the better of me) I have another look at what happened last Thursday and Friday in the South Australian and Victorian regions of the NEM.
Some snapshots from NEMwatch recording a day where NEM-wide demand breached 33,000MW and prices spiked above $1000/MWh in VIC and SA
