Two quick notes about what happened in Victoria on Friday 25th January 2019 following conversations with a number of people.
A first look at some of the action seen in the southern parts of the NEM on Thursday 24th January 2019 as a result of the latest crazy heatwave that has afflicted central Australia – particularly affecting electricity supply and demand in South Australia and Victoria
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.

Some initial analysis by our guest author, Allan O’Neil, about what AEMO’s Statement of Opportunities 2017 is saying in terms of this coming summer 2017-18
A brief explainer of what “Unserved Energy” (or USE) actually means, in the context of the AEMO “Electricity Statement of Opportunities 2017” (ESOO) released this week.
Autumn 2017 continues the very rocky experience that’s become “new normal” for the National Electricity Market – with warnings of load shedding for Victoria and South Australia this week and next
Some quick thoughts about Tesla’s promise to “fix South Australia’s power woes”. Which specific problem is Tesla promising to fix?
Last Friday’s events took South Australia much closer to the brink of another Black System event than many seem to have realised
AEMO issues a Market Notice for a “High Impact Outage” – a term not used since 2012.

Another update, as NSW demand shoots up towards a new all-time record
A quick look into an anticipated stinker of a day in NSW today
Here’s an update on the situation in NSW
A look at the supply/demand fundamentals in South Australia and explaining why load shedding was initiated.
… whilst on the topic of load shedding, here’s a warning for NSW on Friday afternoon.
Deja-vu all over again in South Australia this evening, with load shedding invoked due to climbing (hot-weather fuelled) demand, and insufficient local generation supplies.
It’s not looking that great, currently, for the supply/demand balance in South Australia this week – when viewing predispatch, ST PASA and AEMO’s Market Notices
Wednesday 28th January saw demand across the NEM jump to unprecedented levels, setting a new record of 34,843MW at 16:00 NEM time. On Thursday 29th January, we saw the demand increase still further, leading to prices that stayed high for much of the day (to the point where the Cumulative Price Threshold was reached in VIC and SA and price caps were imposed), and a relatively small amount of involuntary load shedding occurring in VIC and SA.
