The volatility that has been with us for weeks now (particularly QLD and NSW), and the dramas unfolding at Callide power station, prompted me to have a broader look at the availability of black coal plant across QLD and NSW, and compare this to prior Q2 periods.
It was volatile this morning well past that’s become ‘normal’ and the volatility has returned (as I expected it would) this evening. Here’s the snapshot of the 17:20 dispatch interval…
A short article noting volatility rolls into Thursday evening, 10th June 2021
A short note about the first of the volatility on Wednesday 9th June 2021.

Only two dispatch intervals (thus far?) of extreme pricing tonight for QLD and NSW (Wed 2nd June 2021). Here’s the first one…

An unfortunately timed significant slump in output across all Wind and Large Solar plant in NSW was another of the factors contributing to the price volatility seen in NSW last week.
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.
Third day in a row we see volatility in NSW (and QLD) … and this afternoon AEMO contracts, and then dispatches, Reserve Trader in NSW

Spurred by a number of concurrent requests I’ve returned to the pattern of prior analysis of Q2 prices (completed in 2016, 2017 and 2018) to look at what’s changed for Q2 2020 that’s just ended. Some stakeholders clearly taken by surprise. Analysis includes the SWIS in Western Australia
