One image from NEM-Watch today to record a higher demand day in Queensland driven as the heat wave that afflicted NSW yesterday and the southern regions last Friday.
What’s most noticeable in this snapshot is how NEM-wide demand is amazingly low, for a summer week-day (because of the much milder conditions down south that are hopefully assisting with containment of the bushfires burning there).
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.
Both the QNI and the Heywood interconnectors tripped around the same time on Saturday 25th August 2018 (not apparent at this time which one was first, and why), leading to both QLD and SA regions being separately islanded from the rest of the mainland NEM. This also contributed to over 1,000MW of load shedding in NSW and VIC, and presumably some frequency excursions in QLD and SA.
This week saw very low average prices across the NEM (below $21/MWh average across the week in all mainland regions).
Except for 2 half-hours in Tasmania on Tuesday 7th February (when the price rose to just over $1,000/MWh), prices in Tasmania remained at and around $30/MWh for the whole week.
