Loy Yang B1 has returned to service on Sunday morning 2nd November 2025 following a planned outage, and a little later than earlier expected (following some earlier aborted attempts on Saturday 1st November 2025).
Here’s a snapshot from the ‘Bids & Offers’ widget in ez2view at the 11:50 dispatch interval (NEM time) looking back a few days such that we can see:
- In the Bid Stack chart, some of the machinations; and
- In the Bids Table, some of the changes in bids.
Amongst the machinations was this trip from 479MW in the 5-minute period to 21:26 (NEM time) on Saturday evening 1st November 2025, which was captured at the time in this ‘Notification’ widget alert in ez2view:
As could be expected, this delivered a clear frequency disruption as shown below – though note that this remained within the NOFB:
Also notable is the tighter control of frequency more generally in this 4-hour time-range, which seems quite likely to be due to the absence of injections of solar (both invisible rooftop PV and larger variable Semi-Scheduled solar farms).
