Latest data from AEMO (from Fri 14th April) suggests Liddell unit 4 might close a couple days later than when we’d looked in February.
Around eight days till the scheduled closure of Liddell’s next-to-close unit (and prompted by an article in the AFR), we take a quick look at how they’ve been bidding.

Second post for this afternoon/evening following AEMO announcement to commence RERT Negotiations for this evening in NSW.
Some late hot weather (in Autumn 2023) is providing for some activity in the market
From 08:00 (NEM time) this morning, the old ‘X5 constraint’ (i.e. formerly formally known as ‘N^^N_NIL_3’) has been split into two (i.e. addressing separately risk of tripping of either/both Bendigo to Kerang 220kV line and Bendigo to Shepparton 220kV line). Here’s a first quick look…
In Part 3 of this Case Study, we look at the source of the Dispatch Interval Availability forecasts for these units at 17:05 on 27th October 2022 (i.e. Self-Forecast or something else, incl AWEFS/ASEFS).
In Part 2 of this Case Study, we look at those 15 x Semi-Scheduled units highlighted with large deviations (mostly under-performance) at 17:05 on 27th October 2022 in order to understand more.
