Evolution of the GSD2019

Our(note D1) Generator Report Card 2018 has been wonderfully successful(note D2).   We appreciate all the feedback we have received in the growing number of months since then!

One of the most common requests we have received has been about updates, which we are addressing as illustrated here:


Beginning with our(note D1) Generator Statistical Digest 2019 we aim to be producing an annual Statistical Digest which will continue to evolve as the National Electricity Market evolves, and will provide a particular focus to performance metrics for the generation sector in the past year.

(A)  Building on the GRC2018

The GRC2018 was structured to contain two core components of value:
Component #1 was ~170 pages of Detailed Analysis; whilst
Component #2 was 328 pages in what we took to calling a Generator Statistical Digest (i.e. part 3 in the Report Card).

Both components in the GRC2018 delivered significant value in different ways:

~170 pages of Detailed Analysis 328 pages of DUID-per-page Statistics
In this component we invested a gargantuan number of hours in completing a series of overlapping analytical projects to deliver discrete pieces of insight.

This was a time-intensive process that focused the analysis on what we saw as some of the most important aspects of this energy transition.


In contrast, the statistical digest was (almost) automatically generated with operational data over the 10 year period (from 1st January 2009 through until  31st December 2018).

This was only possible after a parallel investment of a mammoth number of hours:
1)  to convert raw AEMO data into metrics actually useful for these purposes.
2)  to prepare the format of the “page per DUID” that was Part 3 of the Generator Report Card.

Hence it was logical for us(note D1) to decide to update each component separately, moving forwards:

… updating the Detailed Analytical Component?

(we’re deferring this)

…updating the DUID-per page Statistical Component

(we’re building this)

To update this analysis would necessarily mean extending it further.

Whilst we certainly understand a number of areas in which we would like to drive the analysis further:
1)  It would require a similarly massive resource commitment;
2)  Which we just cannot manage at this point in time, given our other prior commitments.

It might be a few years before we are ready to do that.  This might also be good timing, given the pace of development of this transition and the new challenges emerging.

In comparison (in theory, at least), we thought it would be relatively quick to update what we did for Part 3 of the Generator Report Card, and provide that separately as an update under a different name to differentiate.

Given the nature of the people we are, we’d not be happy to do just that, however.

Instead, we decided to invest more time into the development of a new product out of what we did in Part 3 of the Report Card:
1)  Which could stand in its own right, as a discrete product; and
2)  Deliver value to clients – perhaps even on the basis of an annual update (though this is definitely not promised now).

So, following from the above train of thought, we emerged at a design for a Generator Statistical Digest enabling release on 28th January 2020 (only 4 weeks after the end of the year in focus).

(B)  What the Generator Statistical Digest 2019 is…

Following discussions internally (and with some clients – thanks!), we settled on a design that started with what we completed for Part 3 in the Generator Report Card – but extended it in three key ways, illustrated as follows:

Updating the Date Range Updating the DUID list Extending to 2 pages with a focus on 2019
The page we have already designed is focused on the most recent 10-year range.

It’s logical for this to cover the period 2010-2019 with data till 31st December 2019.

We’ve called this the ‘A’ Page.

Of course, part of the value of this product would be that it included stats for units that only began operations in 2019.

Because we’re thinking of extending this to two-pages-per-DUID we propose to also drop any older unit not operational in 2019 (e.g. no pages for Hazelwood).

Extending to two pages per DUID we have added in a ‘B’ Page.

This gave us a chance to focus on producing useful metrics that would bring us one step closer to answering new questions we have been pondering.

These questions have arisen as a result of any or all of the following:
1)  The analysis performed with the Generator Report Card 2018 (which answered some questions, but created others);
2)  Where we are taking some of our software into the future (particularly ez2view, such as in this animation); and
3)  Further evolution of the NEM.

We’re looking forward to your feedback on the GSD2019.

(D1)  Who’s the “we” who prepared the GSD2019

 As with the Generator Report Card 2018, this was a collaborative effort, discussed here.

(D2)  How do we measure the success of the GRC2018

The GRC2018 has been wonderfully successful.   Even past the release of the GSD2019 we have continued to receive orders for the earlier  GRC2018.  However it’s also more than that…

When we speak of “the success” of the GRC2018, there are a number of specific points of feedback we are speaking about, including these:

1)  The Generator Report Card has been widely purchased and read across the Australian energy sector (wholesale participants, but also a diverse range of other stakeholders).

2)  We have been inundated with favourable feedback from those who have purchase the Report Card (it was released on 31st May 2019 and the new clients, and the feedback, continue to flow).  Only a couple days after release we summarised some early feedback here, and it has continued to flow in over the following months.

3)  One of the most common questions we’ve been asked is when we would consider updating the report – and whether it might be a regular publication in future.  Being on the end of a regular stream of feedback like this helps to reinforce our sense of success.

4)  However perhaps the greatest measure of success, for us, is that the GRC2018 (and also the GSD2019) makes it much, much easier for to answer questions (and a diverse range of them!) about the performance of generation assets in the NEM.
