Given a couple earlier articles about the expectation for high wind yield on Tuesday 2nd June 2026 and Wednesday 3rd June 2026, it’s worth a quick article on Wednesday morning with this snapshot from NEMwatch at the 08:00 (NEM time) dispatch interval:
I’ve trimmed the ‘Fuel Type’ chart to focus on wind yield over the past 24 hours:
1) Note that it ramped up into yesterday evening
… though (as per the note) this might have been just due to lower curtailment, rather than windier conditions.
2) That meant for a peak across the period of 9,135MW at 20:45 (NEM time) on Tuesday 2nd June 2026
(a) still ~1,000MW below the all-time record (set on 25th July 2025).
(b) and fairly aligned with prior forecasts.
3) I’ve also noted:
(a) that the wind output drove prices to a ‘negative LGC’ overnight in SA and VIC (albeit with LGC price in the doghouse in recent times, this bid price level is much closer to $0/MWh than in years gone by).
(b) whereas in QLD, NSW and TAS prices were above $0/MWh … and even above $100/MWh at times in QLD.
It would be great if you could do an article looking at the SA yields over the past 2 weeks. There were a few points where total output was below 10MW, this would be a record low in the context of the total installed capacity.
