The Generator Statistical Digest 2022 (GSD2022) is released

It’s Tuesday 31st January 2023, and we* are pleased to release the GSD2022 … following some focused effort since late in 2022.

* 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)  What is the GSD2022?

The GSD2022 is an update on the issues that came beforehand (the 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:

Because the number of units participating in the NEM continues to grow (with the change-out of larger thermal units for multiple smaller units) the GSD2022 now comes in at a whopping 856 pages in a single electronic PDF (such that the printed & bound copy we now supply in two Volumes).

For each (and every!) of the DUIDs that operated through some portion of CAL 2022 in the ‘ENERGY’ market (i.e. for which AEMO published some non-zero InitialMW data) we have included two pages:

‘A’ Page
… ten years 2013 to 2022
‘B’ Page
… additional details for calendar year 2022
This page was closely based on the ‘page per DUID’ supplied in Part 3 of the GRC2018 (with enhancements in a number of ways, based on feedback from clients).

It is designed to provide monthly statistics covering the most recent 10 years of NEM operations.

The image below shows the A Page for Darling Downs CCGT (DDPS1).

Click to open the image to see more detail about the ‘A’ Page.

The ‘B’ page design was introduced with the GSD2019 to provide a particular focus to the most recent year – and has been updated (based on customer feedback, and NEM evolution) since that time.

It is designed to provide a detailed view of a range of additional statistics – particularly focused on 12 months of the most recent year.

The image below shows the B page for BRAEMAR2 … one of the units at Braemar A (or Braemar 1) Power Station.

The advantage of this format is that it enables data to be reported, on the same basis, for all DUIDs!

(C)  Several Analysts present some initial insights, from the GSD2022

In conjunction with the launch of the GSD2022, we’ve asked several different analysts to independently delve into the detail of data published in the GSD2022 and share some of the things that jumped out to them in the following articles:


Analyst Brief description of what they covered

Allan O’Neil

Allan O'Neil

Allan O’Neil is one of our most frequency guest authors on WattClarity.

With respect to the GSD2022, Allan has shared his thoughts here:

1)   On Tuesday 31st January 2023, Allan used the GSD2022, along with other sources, to write ‘Farewell Liddell’, which is a timely article given the fast-approaching closure of the 3 remaining units at the Liddell Power Station.

Paul McArdle

Even prior to release, we’d published a couple articles referencing early drafts of the GSD2022:

1)   Back on 28th December 2022, I’d published ‘Media buzz about compensation for Gladstone Power Station under the coal price cap’ … whilst we were reviewing a draft at the time.

2)  Then on Friday 20th January 2023, I’d published ‘Using the (draft of) GSD2022 to investigate those Solar Farms suffering significant curtailment’ to follow on from some reporting of analysis performed by a bunch of analysts from ANU.

Now that the GSD2022 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 GSD2022).

Dan Lee

In recent times Dan Lee has been contributing an increasing number of articles for us at WattClarity.

Following the release of the GSD2022, Dan has written the following articles referencing the GSD2022:

1)   On the day of its release, and inspired by an article on RenewEconomy, Dan wrote ‘Examining the $112/MWh revenue that Genex’ Jemalong Solar Farm generated in Q4 2022’.

David Leitch

David Leitch is a guest author who publishes very occasionally on WattClarity:

1)   David’s much more prolific with articles on RenewEconomy.

2)  Indeed, of the 7 articles David had published on WattClarity prior to this time, 2 were about earlier issues of the Generator Statistical Digest

(a)  On 1st February 2021 about the GSD2020; and

(b)  About the GSD2019 on 28th January 2019.

With respect to the GSD2022:

1)   On 7th February 2023 he posted some thoughts in ‘The GSD2022: A labour of love’.

On 2nd May 2023, Tristan Edis published ‘Australia’s Renewable Energy Boom – The Good, The Bad and the Downright Ugly’ after using the GSD2022 to take a look at different aspects of the performance of various wind and solar assets across the NEM.

This article triggered much discussion, including a follow-on article from Allan O’Neil, who wrote ‘Renewable curtailment – forced and not quite so forced’.
