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.
The prior record for ‘minimum demand’ in Victoria seems to have only lasted 8 short weeks, with the level nudged still lower on a sunny Sunday 1st November 2020 (coincident with a bit more freedom for Victorians after lockdown).
One of 12 articles on the months past in the NEM. Here we present a detailed analysis of prices in each region of the NEM, for the month of April over the past 10 years.
