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.
A recent development over in the WEM (paying energy users to consume, when there’s too much solar and wind) highlights the lack of foresight in the NEM … where we’ve implemented a significant reform (yet to start) that will do nothing to address negative prices.
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.
Following the release of GenInsights Quarterly Updates for 2023 Q3 we’ve chosen to share here one of the clear challenges for large-scale VRE that is emerging (particularly in 2023 Q3) due to the rise and rise of rooftop PV.
A quick look at monthly stats shows that, whilst it’s been blowing a gale in SE Australia in recent days, it’s not yet set a new ‘peak instantaneous wind farm output’ record.
