It’s Thursday 15th February 2024, and we* are pleased to release the GSD2023 … following a focused effort across both teams over the past ~8 weeks.
* As with prior issues, it’s been a collaborative effort:
(a) across a combined team (across Greenview Strategic Consulting and also some of us here at Global-Roam Pty Ltd),
(b) and with some highly valued assistance from others as well.
(A) How we evolved to the GSD2023
The GSD2023 is an update on the issues that came beforehand (the GSD2022, GSD2021, GSD2020 and GSD2019 … all of which followed as an update to, and extension of, the statistical component that formed ‘Part 3’ of our very widely read Generator Report Card 2018 (GRC2018).
The evolution is illustrated here:
You can find more information about what came beforehand here on the focused section of the WattClarity site.

We look forward to hearing back from you!
(C) What’s the GSD2023 (including what’s new)?
Unlike the preceding issues (which were 2 x Volume publications of ~800 pages), the GSD2023 is a ~1200 page document that requires moving to a 3-volume format as follows:
| Volume 1 containing statistics new to the GSD2023 ~400 pages |
Volume 2 ‘A’ Page and ‘B’ Pages DUIDs until KPP_1~400 pages |
Volume 3 ‘A’ Page and ‘B’ Pages DUIDs from LADBROK1~400 pages |
|---|---|---|
| In Volume 1 we have included familiar content, and also a considerable volume of new content to provide an even richer statistical record of operations in Australia’s National Electricity Market.
1) Familiar content includes: (a) The popular Glossary, which contains much more than published here. (b) The focused ‘FCAS Cost’ calculations, by FCAS Portfolio. … and more 2) New content includes both: (a) A focused review of the operation of Semi-Scheduled units through calendar 2023:
(b) A 10-year review of every unit that participated in at least one FCAS market through 2023.
Click through on the links above for more information about this new content. |
Moving from the GSD2022 to the GSD2023, the main set of data you’re used to seeing in the earlier issues is now located across Volume 2 and Volume 3.
This data is historical performance statistics for units that were operational in the ENERGY market for some time of calendar 2023 – this includes:
This content is described further below. |
|
A useful reminder is that the GSD2023 (with a focus on calendar 2023) provides the second edition covering a full year of operations under Five Minute Settlement.
Volume 2 and Volume 3 – for units operational in the ENERGY market
Volumes 2 and Volumes 3 are for units operational in the ENERGY market through some part of 2023 – and hence are largely similar to the structure of the GSD2022, GSD2021, GSD2020 and GSD2019, which came beforehand.
For all units that operated through some portion of the 2022 calendar year (i.e. for which AEMO published some non-zero InitialMW data) we have included two pages:
| A Page 10 Year Profile 2014 to 2023 |
B Page 12 Month Detailed Profile for the 2023 Calendar Year |
|---|---|
| The A Page for each unit contains performance and financial metrics for the previous ten calendar years (i.e. 2014 to 2023).
Metrics included on this page include monthly revenue, monthly availability and capacity factors, volume bid in price bands, unit starts, operating hours, etc. The image below shows the A Page for ER03.
There’s plenty on this page, spanning the most recent 10 years in the ENERGY market!
|
The B Page for each unit contains more detailed performance and financial metrics for the previous calendar year only (i.e. 2023).
Metrics included on this page include daily output, daily availability and capacity factors, monthly revenue, hours constrained, etc. The image below shows the B page for BRAEMAR1.
This is a detailed review of 2023.
|
The advantage of this format is that it enables data to be reported on the same basis for all units!
(D) What is the GSD2023 Data Extract?
After we released the GSD2020, we received a number of requests from clients who wanted us to collate and release a separate extract of the data contained within the final document:
1) We completed the additional work to make the GSD2020 Data Extract available in March 2021 …
2) … so we did the same for the GSD2021 and GSD2022;
3) and now have done the same for the GSD2023 (complete with the much larger data set).
The extract is available as an optional extra for those who wish to complete their own analysis of the data that we have calculated and processed.
There is an option to order the data extract on the order form linked above.
(E) Several Analysts present some initial insights, from the GSD2023
In conjunction with the launch of the GSD2023, we’ve asked several different analysts to independently delve into the detail of data published in the GSD2023 and share some of the things that jumped out to them in the following articles:

Now that the GSD2023 has been released, more articles will surely follow…. When we publish these, we’ll try to remember to link them in here (and will also tag them as GSD2023). |

Paul McArdle

Nothing prior to release, with respect to the GSD2023:
… and we had to wait till 4 weeks after the GSD2023 had been released, to start to see some articles: 1 On Sunday 17th March 2024 , Paul wrote ‘How many Semi-Scheduled units have taken advantage of the market change that went live on 7th Aug 2023?’; and then 2) Next day (Mon 18th March), Paul wrote ‘How many Semi-Scheduled units were submitting Self-Forecasts through 2023 (and how many of these were actually used in dispatch)?’. |

Dan Lee

Even prior to release, Dan was able to publish with respect to the GSD2023:
1) Whilst the GSD2023 was still under development (on 11th January 2024), Dan referenced the earlier version in writing ‘The early wind farms reaching 20 years: how are they performing?’ (with 2 pages from the GSD2022 for Macarthur Wind Farm). 2) On 14th February 2024, Dan wrote about how the ‘AGL half-year results point to ‘strong financial performance’ for Torrens Island BESS (but not directly through the spot market)’ Now that the GSD2023 has been released, more articles have followed: 1) On 4th March 2024, Dan wrote ‘A look into the performance of Genex’s four DUIDs in 2023, following takeover bid from J-Power‘ 2) On 6th March 2024, Dan published a longer review of battery performance ‘State-of-charge: a peek into the economics and performances within the NEM’s battery fleet‘ 3) On 7th March 2024, Dan wrote ‘Keeping up with the curtailment: 3.7TWh of semi-scheduled economic and network curtailment estimated in 2023‘ |
