Prompted by a question by a client in a training session for a new ez2view user, guest author Allan O’Neil has written 2,940 words to explain the price outcome in one particular dispatch interval for one particular region (19:05 on Tuesday 11th February 2025 in South Australia). Strap in, because it’s a good illustration of why the simple ‘merit order’ bid stacking model is sometimes (often!) way too simplistic!

We just witnessed another eventful Q2, with at least four drivers contributing to significant price volatility. This is our annual review of Q2 prices, where we compare these outcomes against the long-term trend.
One year on from a market-wide suspension, Dan Lee provides a review of Q2 prices for 2023 so that we can examine some of the longer-term price trends.
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.
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

In some cases results are second worst in 20 years.
A year on from my review of “remarkable” prices seen in Q2 2016, I return to the same analysis and update for Q2 2017. Outcomes are even more extreme…
Some initial analysis about the remarkable pricing outcomes seen across all regions of the NEM through Q2 2016
