This morning (Thursday 27th August 2020) we saw the AEMO release the 2020 edition of the Electricity Statement of Opportunities.
Without resiling from last week’s criticism of how the headlines from AEMO’s 2019 Electricity Statement of Opportunities (ESOO) were communicated, it’d be churlish for me to fault the depth of…
I’d rather not add to the number of conspiracy theories in circulation, but I wonder if there’s a conspiracy to make understanding our electricity system in general, and its reliability…
Some initial analysis by our guest author, Allan O’Neil, about what AEMO’s Statement of Opportunities 2017 is saying in terms of this coming summer 2017-18
Some initial, scattered, thoughts (late on the day of its launch) about the AEMO’s first production of the Electricity Statement of Opportunities for 2009
Wednesday 13th January 2021 was a busy day in the NEM, with a couple of different events occurring. In this article we explore a sudden and unexpected drop in output across both rooftop PV and large-scale solar in South Australia that delivered both price spikes, and also broader questions about emerging challenges for the grid (and market).
Following a week where several days saw price volatility in NSW (with this being so extreme that Reserve Trader was triggered on Thursday 17th December) we’ve taken a look at the comparative performance of coal units across the NEM (and particularly in NSW) compared to prior years.
Records continue to tumble in the off-season, with the rise of rooftop PV. Both South Australia and Whole-of-NEM hit new low points Sun 11th October 2020.
Only 52 days after I initially envisaged being able to have this article published, a couple things today have prompted me to post this drain-dump of concerns that have been jangling around in my head – related to possible risks that COVID might pose in the NEM.
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.
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 the AEMO have called for expressions of interest for the ‘Unscheduled Short-Notice RERT’ for summer 2020-21.
An article today providing links to the ‘Renewable Integration Study’ which the AEMO released today, and also to the headline media coverage I have seen on my quick scan this morning.
… because the evidence currently suggests that this is just not the case (in this article I explore and explain further)
Guest author, Allan O’Neil tries to piece together further detail of what is intended with the apparent tightening of the Reliability Standard (which has sat at 0.002% USE for many years).
Perhaps missed amongst all the bushfire-related action in the NEM, the SA Minister for Energy last week initiated the Retailer Reliability Obligation. Guest author Allan O’Neil tries to come to grips with what this means, and what happens next?
Guest author, Allan O’Neil, provides us an update today on what we can see about summer 2019-20 (in the physical market, and the financial market), now that it is only just around the corner.
With summer 2019-20 fast approaching, we’ll use the refresher on the two core components of risk (probability and consequence) to unpick what the real issue is with respect to concerns about overheating electricity supplies this summer, especially in the Victorian region.
