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.

The framework we used to analyse the extent to which coal-fired power is “dependable” in the Generator Report Card, and the extent to which it’s been changing.
With AEMO forecasting LOR3 (i.e. load shedding) in NSW for periods of time on Monday 16th December 2024, in this WattClarity article we take a first look. More to come *as time permits* (and as situations change, etc…).
On Tuesday 26th August 2025 the VP5 unit came offline, with rebid reasons suggesting that ‘turbine vibrations’ were a factor. We take a look ~10 days later.
Following a week where several days saw price volatility in NSW (with this being so extreme that Reserve Trader was triggered on Thursday 17th December) we’ve taken a look at the comparative performance of coal units across the NEM (and particularly in NSW) compared to prior years.
