The Generator Statistical Digest 2021 (GSD2021) is released

Today (Monday 28th March 2022) we are pleased to release the GSD2021 (a.k.a. Generator Statistical Digest 2021) … following some focused effort over the past couple of months from a combined team (across Greenview Strategic Consulting and also some of us here at Global-Roam Pty Ltd, and with some highly valued assistance from others as well).

(A)  What is the GSD2021?

The GSD2021 is an update to the three statistical reports that came beforehand – the GSD2020, the GSD2019 and the statistical component that formed ‘Part 3’ of our very widely read Generator Report Card 2018 (GRC2018).

The GSD2021 is intended to be read in conjunction with GenInsights21 – the 600-page analytical report that was released on 15th December 2021 as an update to, and extension of, the 180-page analytical component in the GRC2018 as shown here:

For all DUIDs that operated in the ENERGY market through some portion of CAL 2021 (i.e. for which AEMO published some non-zero InitialMW data) we include two pages:


‘A’ Page
… ten years 2012 to 2021
‘B’ Page
… additional details for CAL2021
This page followed the ‘A’ page design used in the GSD2020 and GSD2019 – which was itself heavily 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).

For the GSD2021, this ‘A’ Page looks as follows:


Click here, or on the image, for more detail about the ‘A’ Page.

This page was closely based on the ‘B’ page design used in the GSD2020 and the GSD2019.  This page was added as an extension to the GRC2018.

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

For the GSD2021, this ‘B’ Page looks as follows:

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

(C)  Insights from each issue of the Generator Statistical Digest

To give you some sense of how you might use use each issue of the Generator Statistical Digest, we’ve been trying to get into the habit of publishing various pieces of analysis that serve two purposes:

Purpose #1 = first and foremost, these articles must provide value to WattClarity readers in and of themselves.

Purpose #2 = however beyond this, they also showcase some of the value that clients can access themselves through each annual update of the Generator Statistical Digest.

Now that we have released a number of sequential annual updates, we can begin collating these insights below here:

(C1)  Insights to come, from the GSD2021

We’ve been otherwise focused, so have not yet invested time to see what we could glean from the GSD2021 – however we expect that this will come in the future.  When we do this, we’ll try to remember to tag those articles with ‘GSD2021’ and/or ‘Generator Statistical Digest 2021’ … so you can find them at those links.

(C2)  Insights a year ago, with the GSD2020

We released the GSD2020 a little over a year ago, on 31st January 2021.  That year we were able to feature articles from a range of different analysts, including the articles linked here:

(a)  Allan O’Neil wrote about ’Transition Fooled?’
(b)  Ben Willacy wrote about ‘Supply side price drivers in the NEM’
(c)  Mark Stedwell wrote about ‘Energy Transition: it was Full Steam ahead in 2020!’.
(d)  Marcelle Gannon wrote about ‘Using the GSD2020 to explore operating patterns across generation types’
(e)  David Leitch shared ‘Highlights from the 2020 GSD’,
(f)   There were several articles I published, including ‘Prior to the wider release of the GSD2020 … here’s a 10-year trend of bidding behaviour’
(g)  Nick Bartels shared some ‘Analysis of Large Thermals using the GSD2020’
(h)  Jonathon Dyson suggested that ‘Solar Returns – Ain’t what they used to be’,

… and that’s only some of the articles published that drew from the GSD2020 (the GSD2021 is similarly powerful!)

(C3)  Insights shared from the GSD2019

We released the GSD2019 back on on 28th January 2020.

With reference to the GSD2019, we had these five analysts sharing some insights on the day of release … with other insights coming after that time:

(a)  Allan O’Neil published his article ’How good is solar farming?’,
(b)  Ben Willacy wrote about What lies ahead for the NEM in 2020? Some lessons from 2019’.
(c)  David Leitch provided Selected initial observations from the Generator Statistical Digest 2019’.
(d)  Jonathon Dyson shared this Understanding the NEM through the lens of the GSD2019’.
(e)  Whilst I wrote about Review of extremes in ‘Raw Off Target’ performance** through 2019, with the Generator Statistical Digest 2019’.

** As an aside, this analysis of ‘Raw Off Target’ was extended on within Appendix 17 (‘Aggregated Raw Off-Target’ for Coal vs Wind+Solar) within Volume 2 of GenInsights21 just recently, on 15th December 2021.
