(The main part of) IESS goes live today – Monday 3rd June 2024
A short note (on Monday 3rd June 2024) with the IESS changes going live today.
More detail on the poor wind yield through (most of!) April and May 2024
With the April-May 2024 period ending with 3 days during which it blew a gale, this wind powered energy generation provided some small boost to aggregate results in 2024 that disappointed when compared against 2023, 2022, 2021 and 2020.
Highest-ever wind yield … *and* worst wind yield since June 2017!
… it does not seem logical that both can be true, but (from our look at the numbers) it does appear to be!
How predictable is the wind (a short Case Study of Thursday evening 30th May 2024)?
An (initial and) short review of the solid block of high aggregate wind yield over the ~3 day date range (late Tuesday 28th May 2024 to late Friday 31st May 2024) … and how much this was expected in advance.
New all-time record, for NEM-wide wind production on Thursday evening 30th May 2024
A short note (on Thursday evening 30th May 2024) to record the NEM-wide wind production exceeding the prior ‘all time’ record, set 11 months previously. More remarkable after a very lacklustre last ~8 weeks.
Aggregate wind production NEMwide ramps up (close to all-time maximum!) to round out an otherwise low-yield May 2024
Unlike the first ~28 days in the month of May 2024, the aggregate production of power from Wind Farms across the NEM has ramped up from late Tuesday 28th May and reached a high point Thursday morning 30th May 2024 only 371MW below the all-time maximum production.
What impact did the extension to Eraring have on traded prices for NSW Futures?
Reaching for the same NEMreview query we’ve used a few times in 2024 Q2, we take a look at how futures prices have traded in NSW, following the announcement of agreement to extend the service life at Eraring Power Station.
(Easily* the) highest aggregate wind production, thus far in May 2024
It’s Wednesday morning, 29th May 2024 and we’re seeing what’s easily the highest aggregate instantaneous production from Wind Farms in the month of May 2024.
Afternoon snapshot on Tuesday 28th May 2024
A quick afternoon snapshot of the NEM for the 16:00 dispatch interval on Tuesday 28th May 2024 in NEMwatch highlighting a couple things
Eraring Unit 1 comes offline for Economiser Tube Leak
Roughly 48 hours after Eraring unit 2 came back online (Sat 25th May 2024), Eraring unit 1 has come offline (Mon 27th May 2024) on a forced outage.
The ‘N::N_CTYS_2’ constraint equation will be invoked for another 11 days … out till Friday 7th June 2024
The AEMO has extended the scheduled invocation of the ‘N-CTYS_3L_WG_CLOSE’ constraint set (which contains the ‘N::N_CTYS_2’ constraint equation – one factor in the outcomes on Wed 8th May 2024).
There might be a sustained burst of wind generation to finish off the month of May 2024
AEMO’s ST PASA forecasts suggests that we might see a ~3 day period of stronger aggregate production from wind farms across the NEM to finish off the month or May 2024.
Low aggregate wind yield after sunset continues – Sunday 26th May 2024
The pattern of low aggregate wind production in the evenings after sunset (whilst demand is still peaking) continues … into Sunday 26th May 2024.
Eraring Unit 2 makes it back online, Saturday evening 25th May 2024
Eraring Unit 2 commenced return to service on Saturday afternoon 25th May 2024.
Low wind yield (again!) during sunset … this time Saturday evening 25th May 2024
For (at least) the third evening in a row (i.e. after sunset, and in line with evening peak in demand) aggregate production from all wind farms across the NEM has been quite low … today being Saturday 25th May 2024.
Low wind again on Friday 24th May 2024 … how low was wind yield for April and May?
A similar situation to wrap the working week (on Friday 24th May 2024) with low wind yield across the NEM persisting.
Also <40 days till the return of Barron Gorge
A quick update on the return to service expectation on Barron Gorge hydro power station.
Callide C updates – operations (<40 days till RTS!), and in the courts
At the end of an eventful week in the NEM, here’s an update on a few fronts with respect to Callide C.
NEM-wide aggregate wind yield under 500MW on Thursday evening 23rd May 2024
As the sun sets on Thursday 23rd May 2024 (the day of the announcement of the extension to the Eraring service life) we see aggregate wind yield dropping below 500MW.
