A client sent in this ez2view image this afternoon pointing out another factor that’s been occurring in the absence of 4 x Callide units – markedly increased production from gas-fired generation.Read More
Winter 2020 in the NEM
A collection of articles discussing events that occur (or are forecast to occur) through winter 2020 in the NEM
Out of curiosity, and driven by questions received from several people, I’ve invested a bit of time today to delve further into the record low level of Scheduled Demand seen in the Victorian region (and perhaps also across the whole of the NEM) on Saturday 29th August 2020.
Victorian Scheduled Demand plunges in the middle of the day, Saturday 29th August 2020 (a new daytime record low in NEM times?)
Have not checked thoroughly, but a quick scan suggests that the low point for Victorian Scheduled Demand at 13:05 today was a new record for minimum (daytime) demand. If it is, this would be an uncanny coincidence given …
Some SMS alerts notified me of some volatile dispatch intervals this evening in mainland regions. So I took a quick look…
Solar eats a large hole in QLD daytime Scheduled Demand … lowest level in 16 years on Sunday 23rd August!
Tis the season for records, it seems, with Queensland seeing a very low level of Scheduled Demand during the day today – Sunday 23rd August 2020.
Friday 21st August 2020 sees a new record set for peak and average production across Wind Farms across the NEM
Yesterday (on Fri 21st Aug 2020) we saw a new record set for BOTH daily peak instantaneous output across all wind farms in the NEM, and also daily average output across all wind farms in the NEM.
In this 5th article in a series, we look at the impact on electricity consumption of Stage 4 Lockdown associated ‘State of Disaster’ in Victoria
Some quick notes today, to document high-level data (to be explored later) relating to some significantly depressed solar harvest data today due to the widespread cloud/wind event.
A short review, as it happens, on a day where renewable production reached 10,000MW in aggregate across the NEM.
Marcelle uses the latest release of ez2view (v126.96.36.1995) to further investigate the impact of low dispatch prices in QLD on Saturday July 4 2020.
Some quick reflections on a day that saw spot prices in QLD down below $0/MWh for most of the period seeing strong daylight hours, hence strong injections from rooftop PV systems.
During another week that showed signs of the challenges facing all generators (new and old) in relation to spot prices for energy, invitations were delivered for discussions that will happen on 15th July.
A brief look at what’s been happening at Bald Hills Wind Farm – over the 18 months since January 2019, but most particularly in the past couple weeks where output has dropped down near zero.
Yesterday evening (Tue 9th June 2020) saw an example of ‘dunkelflaute’ across the NEM. It’s a phenomenon we will see increasingly as the transition progresses, so it’s something we should be seeking to understand, and address, with real world solutions and not rose coloured glasses.
The University of Queensland’s project team that was involved with the installation and operations of their 1.1MW Tesla battery presented a webinar and exhaustive Q&A on the first results of the project.
A quick look at the two units tripping at 13:33 on Sunday 7th June 2020, and some earlier operational problems the day before (perhaps unrelated).
