Catching up on a few tasks overhanging the holiday weeks, we noted how the spot price in South Australia dropped below zero (and almost did the same in Victoria) on an Anzac Day with low demand coinciding with high wind production levels.
Above, for future reference, is a snapshot of the incident in NEM-Watch v9.
Note (highlighted) the significant drop in demand in the Victorian region which contributed to the drop in prices in both regions.
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.
From one extreme (perhaps lowest ever in June 2017, on like-for-like) to the other (new record production) in the space of just one month for aggregate wind in South Australia
Looking back at Tuesday 13th April 2021 – a day in which the ex-tropical cyclone Seroja in Western Australia caused some wobbles in rooftop solar PV output in South Australia.
Our various dashboard views of the NEM (NEMwatch, ez2view and deSide) have been showing what’s seemed like increasing numbers of zero and negative prices in the NEM recently – particularly in QLD. Coupled with this we’ve seen various commentary on social media. Hence we took a more statistical look at what’s actually been changing…
Alerted by our NEMwatch dashboard, I delve into the data and see a scary degree of correlation between the (very low) output of wind farms in south-east South Australia, and (similarly low) output from newer wind farms in northern NSW.
