An astute reader noted to me about the Central-to-Southern constraint binding today in Queensland, one of the rare days where I did not have an ez2view dashboard display alerting me to its occurrence.
However I do have a brief period now to wind back the clock through “Time Travel” in the software to snapshot the 12:25 dispatch interval as an example of what happened:

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.
Returning to the theme of analysis of Q2 prices (completed in 2017 and 2016 due to Q2 historically being an uneventful period) we see that prices have backed off from the “off the charts” level of 2017, but are still much higher in all regions than most other regions. In some cases results are second worst in 20 years.
