In recent weeks, we’ve written several times about a short-notice outage required at ER03 – which appears to be due to issues on one of the unit’s ID fans.
- Last week (on Tuesday 23rd September 2025) with ‘AEMO oscillates warnings – possible need to intervene in NSW on Thu 25th Sept 2025 for System Strength reasons’
- On Wednesday 24th September 2025 with ‘ER03 now (again) slated to come offline early Thursday morning 25th September 2025’
- On Thursday 25th September 2025 morning with ‘The start of the unplanned outage at ER03 is delayed till early Saturday morning 27th September 2025’ …
- Then last Friday 26th September 2025 (6 days ago) with ‘Start date of short notice outage at ER03 delayed again, now Friday 3rd October 2025’
So it made sense to wrap the story up with a note that the unit came offline this morning Thursday 2nd October 2025 – as captured at the time in this ‘Notification’ widget alert in ez2view:
So an updated view of the expectations for Availability in PD/ST PASA within ‘Forecast Convergence’ widget in ez2view is as follows:
With respect to this image:
1) Remember that it allows one to ‘look up a vertical’ in order to see ‘that other dimension of time’.
2) And is showing the the new PDPASA/STPASA data published (which went live from 31st July 2025).
3) So we can see that (following the article of 6 days ago) it was this Tuesday 30th September 2025 when the decision was made to bring the unit off a day earlier than tomorrow (i.e. Thursday 2nd October 2025 )
4) And is planned to be out for at least until the end of the ST PASA run (i.e. offline into next Thursday 9th October 2025)
… if we check into the MT PASA DUID Availability data in the ‘Generator Outages’ widget in ez2view, we see the expected return to service is sometime on Monday 13th October 2025:
Completing the quick picture (at least for now) here’s a view of recent bids in the ‘Bids & Offers’ widget in ez2view (layout tweaked slightly in an in-development v9.14.* version I’m testing out at present):
