A short article fro Monday evening with a snapshot from NEMwatch at 17:30 with the spot price up around the Market Price Cap in NSW, VIC and SA this evening:
Paul was one of the founders of Global-Roam in February 2000. He is currently the CEO of the company and the principal author of WattClarity. Writing for WattClarity has become a natural extension of his work in understanding the electricity market, enabling him to lead the team in developing better software for clients.
Before co-founding the company, Paul worked as a Mechanical Engineer for the Queensland Electricity Commission in the early 1990s. He also gained international experience in Japan, the United States, Canada, the UK, and Argentina as part of his ES Cornwall Memorial Scholarship.
Discussion in a number of different places (including an AFR article today) prompted me to pull some data together of how (spot and futures) prices have trended through 2021, and how they changed with the Callide C4 problems.
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.
For several days in early December, temperatures reaching 40 degrees in Queensland and New South Wales cause airconditioning load (and hence total demand) to soar in both regions.
The high demands resulted in very high prices being experienced in both QLD and NSW (and also the SNOWY region). Both VIC and SA were insulated from the high prices because (at least in part) of the fact that transfers over the SNOVIC interconnector were constrained to minimise negative inter-regional surplus

The NEM is certainly creating some volatility alright- https://www.youtube.com/watch?v=CSkFPA81Uws
That’s not mincing words and calls for a response from the CSIRO and AEMO.
