A short note to record a large-size drop in ‘Market Demand’ in the Queensland region on Tuesday morning 14th October 2025, as captured in this ez2view ‘Notification’ widget alert at 07:31 (NEM time):
This is also clearly seen in this snapshot from NEMwatch at the 07:45 dispatch interval:
I’ve annotated the screenshot with some stats, but useful to note that the reduction in Queensland ‘Market Demand’ continued over several dispatch intervals – likely not just because of the morning rise of rooftop PV:
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.

Already we are seeing the highly correlated output of solar PV deliver interesting challenges for the NEM – both to the project proponents themselves, and also to the “everything else” that supplies what’s left of the underlying demand from electricity from any source.
