A month on from the prior low point seen for Scheduled Demand (and Operational Demand) across Queensland in the middle of the day, the low point mark is driven lower still on Sunday 27th September 2020.

This 18th Case Study in the series investigates two separate dispatch intervals showing extreme collective under-performance across all Semi-Scheduled units on Monday 25th March 2020.
A short article today, highlighting the release of this Amperon report for AEMO looking at the way in which the performance of some Large Solar Farms in the NEM were affected by bushfire smoke through summer 2019-20.
Short note to follow presentation by Marcelle Gannon and Jonathon Dyson on Thursday 17th Sept 2020 to an audience organised by Clean Energy Council (CEC).
A short article providing access to the much-talked-about report.
Hot on the heels of a new record low point for Scheduled Demand (a week ago) in VIC, today sees Scheduled Demand in SA plunge to 315MW in the 11:50 dispatch interval on Sunday 13th September 2020.
A quick look at this dispatch interval – as the 17th Case Study in the series looking at extreme results for Aggregate Raw Off-Target for all Semi-Scheduled DUIDs.
This 16th Case Study in a series covers the first ‘extreme event’ into 2019 where there was an aggregate under-performance (compared to Target) across all Semi-Scheduled plant totaling greater than 300MW.
Questions from several readers prompted this quick look at the long-term trend of coal generation.
This morning (Mon 7th Sept 2020) the ESB released its Discussion Paper into the design of NEM 2.0 – with 7 different work streams suggested (and submissions due 19th October 2020).
Prompted, in part, by yesterday’s record low for Victorian demand, today I have finished off my earlier review of what happened on Saturday 29th August (8 days earlier) when demand levels also dropped in VIC, and right across the NEM.
Within the same 24 hour period as California again feels the stresses of its own extremes, we see that Victoria experiences the other side of this energy transition challenge, with a new record low for Scheduled Demand set for *any* time of the day…. in the middle of the afternoon!
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.
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 …
AEMO also published something else today which (whilst not as publicised as the ESOO) will be of keen interest to many stakeholders in South Australia…
This morning (Thursday 27th August 2020) we saw the AEMO release the 2020 edition of the Electricity Statement of Opportunities.
This 15th Case Study is longer than the earlier 14 as it deals with 4 discrete instances of extreme level of collective under-performance, and 1 instance of over-performance, all within a 4-hour timeframe on the same day. A day which appears to have had widespread weather activity affecting the output of BOTH Wind and Solar across 3 Regions. A challenging day!
Some SMS alerts notified me of some volatile dispatch intervals this evening in mainland regions. So I took a quick look…
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.
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.
