In this article we explore the 2024 ESOO, and linked documents, in terms of what’s assumed for coal unit EFOR – and why, in the light of recent improvements in coal unit performance (compared to 2022).
After an initial skim through the 2024 ESOO, here’s (the start of) a collation of thoughts that it triggers.
On Thursday 29th August 2024 the AEMO released the 2024 ESOO (Electricity Statement of Opportunities) for the NEM. Here’s where to get it, and also links to relevant news media articles that we’ve seen.
After skimming through the last twenty editions of the ESOO over the past couple of days, Dan shares some thoughts about what has and hasn’t changed over the years.
Part 2 of this analysis into the latest update of the ESOO, its modelling, and the project development pipeline.
A compiled list of development projects delayed or leaving the market in between the ESOO2023 and its update released two weeks ago. Along with some analysis of longer term trends with the development pipeline.
Following today’s publication of the AEMO has also called for ‘Interim Reliability Reserves’ for summer 2024-25.
It’s Tuesday 21st May 2024 and the AEMO has published an update to the 2023 ESOO … about 8 months since the publication of the prior release, and 4 months before the 2024 ESOO. Some implications for the anticipated closure of Eraring?
The methodology used to assess performance of AEMO’s longer-term forecasts is under review via the consultation process.
In his second article about the 2023 ESOO, guest author Allan O’Neil takes a look at what the AEMO has published with respect to various options for firming capacity to increase the reliability of aggregate supply to below the two thresholds (the Reliability Standard and the Interim Reliability Standard)
Last Thursday (31st Aug 2023) the AEMO published the ESOO 2023, including forecasts of some possibility of unserved energy in Victoria and South Australia this coming summer 2023-24 (above the Interim Reliability Measure). Guest author Allan O’Neil takes a look.
The 2023 ESOO contains some some reporting (and data) about one particular contingency plan … delaying retirement of existing thermal generators (with Eraring a case in point).
Apart from a distraction early this morning, I’ve invested some hours today in review of the 2023 ESOO. Here’s 7 initial observations that jumped out at me.
Here’s my view on whether Figure 2 should have preceded Figure 1 (with respect to projections of unserved energy … USE) in the 2023 ESOO.
One observation about the 2023 ESOO is that EFOR (equivalent forced outage rate) for coal and large gas units is a large and growing challenge.
One observation about the 2023 ESOO is that AEMO is has highlighted the set of constraints modelled is only ‘System Normal’.
One observation about the 2023 ESOO is that AEMO is now modelling (more accurately) the high temperature degradation on wind farm performance.
AEMO notes that ‘Australia’s NEM is perched on the edge’ in the 2023 ESOO, released today (Thu 31st Aug 2023)
On Tuesday 21st February 2023 the AEMO published an update on its 2022 ESOO.
Drawing from GenInsights Quarterly Update for Q4 2022, and the next version of our ez2view software, we take a look at the *current* expectations for closure of Liddell Power Station (within weeks) and Eraring Power Station (in 2025). A segue into this week’s update to the ESOO, perhaps?
