Tarong unit 2 has come offline as previously signalled … slightly earlier than planned (but only after the massive demand peak)

Last Friday 19th January 2024 we highlighted ‘Two coal units to watch, in QLD over coming days – in relation to forecast tight supply-demand on Monday 22nd January 2024’, and then early Monday morning we updated with ‘What about those 2 x coal-fired units in QLD we suggested you watch?’ … at the start of Queensland’s gang-busters demand day.

Of those two units …


Millmerran 1 came offline late on Monday 22nd January

Yesterday (Tuesday 23rd January 2024) we wrote about how ‘Millmerran unit 1 came offline as planned … but only after the massive demand peak’.


Tarong 2 came offline late on Tuesday 23rd January

Last night we received ez2view-triggered  Notification alerts via email, letting me know that Tarong unit 2 (the other unit we were watching) had come offline:


So it’s worth opening up the ‘Bids & Offers’ widget in ez2view to show what’s visible with the unit:


In the rebid reasons (highlighted) there is talk about a revised outage schedule … indeed, we can see the effect of this in the ‘Generator Outages’ widget here:


As highlighted in the grid:

1)   the data now shown for TARONG#2 unit (and all other units) for Thu 25th, Fri 26th and Sat 27th Jan 2024 is ‘stale’ MT PASA DUID Availability data that the AEMO published at 18:00 last Saturday (20th Jan) and has not updated since.

that’s the way this data set works.

2)  as at 18:00 on Saturday 20th January, it had been the plan that the unit would come offline on Saturday 27th January as noted at the time.

3)  We’re assuming that the milder conditions, and condition of the plant, combined to incentivise the operator to take the unit off a couple days earlier.

4)  Current expectation is that it would be back online sometime Friday 9th February 2024.

That’s all for now…
