Worth a short note with this snapshot from the ‘Bids & Offers’ widget from ez2view at 19:00 (NEM time) on Thursday 12th June 2025 to highlight the short-lived return to service at YWPS4:
We can see that the unit:
1) Came back online yesterday evening (Wednesday 11th June 2025) at around 22:00 … thereby missing out on the revenue opportunities that evening; and also
2) The unit came offline today around 15:30 … so also missing the ‘higher and longer’ period of volatility this evening.

Following a reminder in a phone call today, I’ve updated the date range in a NEMreview trend previously used in February to look at percentage of Underlying Demand in NSW supplied for each half hour over the 5 day period Monday 6th May 2024 to Friday 10th May 2024 (which includes 3 volatile periods leading to Administered Pricing).
