Taking a second look at the very early morning volatility in the NSW region on Monday 1st May 2023, we’ve used the ‘Constraint Dashboard’ widget in ez2view to get so far … and then added some *speculation* about how it might have been related to the retirement of Liddell from market systems. Is this accurate?
A very quick look at separate bouts of volatility on Monday 1st May 2023 – firstly in NSW and then later in South Australia.
A quick article on Sunday evening to highlight the difference between sunlight hours and darkness hours in terms of pricing patterns today (the weekend following the closure of Liddell).
As many know, Liddell Unit 1 is slated to close today (the last of the 4 units), Friday 28th April. Unfortunately coincident with that, AEMO is forecasting LOR2 low reserve condition for the middle of the afternoon tomorrow, Saturday 29th April 2023.
Alerted by RenewEconomy on social media that Beryl Solar Farm was offline due to bushfires, I used ez2view to take a quick look.
A quick note to show the last dispatch interval of output from Lidell Unit 4, with the two remaining units slated to follow suit in the coming days.
In an event (that seems) similar to 17th March 2023, a glitch in SCADA leads to the suspension of the market in the Victorian region on Saturday afternoon/evening 22nd April 2023.
It’s Easter Sunday (9th April 2023) and it looks like NSW minimum demand has fallen further from the prior record set 6 months ago.
Given the significance of the event (Reserve Trader almost triggered on Thursday 16th March – 34 days till the closure of Liddell Unit 4) we’re investing some time in exploring more detail of the event. This is Part 1.
A quick record of the start of volatility on Sunday evening 19th March 2023.
A just-announced AEMO market notice has declared a temporary suspension of the NSW market.
Looks like a new all-time record for Operational Demand in the QLD region early this evening, Friday 17th March 2023.
Following last night’s market volatility, QLD’s total demand is currently forecast to go beyond its highest recorded point.
Looks like we’ve (sort of) dodged the Reserve Trader bullet on Thursday evening 16th March 2023 … but still poses plenty of questions.
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…
On Monday afternoon 6th March 2023 a late burst of summer in NSW has driven Market Demand above 13,000MW.
Could be a hot one in (Sydney and) NSW on Monday 6th March 2023 … with AEMO forecasting potential LOR2 low reserve condition.
