Deeper Insights via WattClarity ®

WattClarity® has been in operation since late 2007. The insights shared on WattClarity since that time have been (and will remain) free to access.

From time to time there have been some questions we’ve grappled with that have proved too large to be properly addressed in a single post (and particularly in the time we’ve had available in the lead up to a single article).  From this more detailed analysis occasionally flows more detailed reports – which we have started to describe as WattClarity® Deeper Insights.

Some of these reports are accessible in the listing below:

Topic of the Report About the report

As time permits, and where it is aligned with our core focus on the continuing enhancement of the (software-based) products we serve our customers with, we will be adding in other reports.


More on the GSD2021 (late January release) later – we’re focused on release of GenInsights21 (for December release) first.

Generator Insights 2021


Other priorities have delayed us in getting stuck into this, but we’re underway now and aiming for to release ‘GenInsights21‘ before the end of Q4 2021.  You are welcome to pre-order your copy now.


The GSD2020 was completed in January 2021, and we then commenced the process of separately updating and extending the the 180-page analytical component of the Generator Report Card 2018.

We decided at the time that we would call this Generator Insights 2021  … and we’re looking forward* to having this released in early December 2021 in time for your Christmas stocking.

*  circumstances might change, but this is our current plan.


We had thought, initially, of calling this a ‘Generator Report Card 2020′ but decided against that for several reasons including:

Reason 1)  With other efforts taking priority through 2021 (including many preparations for Five Minute Settlements) the release of this new report will be later in the year than we initially were thinking.

1a)  This enables us to use more data from within the 2021 calendar year.

1b)  Most analysis will be performed with data to 30 September 2021 … but we’re aiming to also include an appendix about ‘Early insights from 5MS’

Reason 2)  In coining the ‘Report Card’ naming for the GRC2018, part of what prompted that name was the inclusion of the ‘page for every DUID’ detailed report card for each unit as Part 3:

2a)  Which has now been expanded separately into the GSD2019 and GSD2020 and is intended to be an annual update;

2b)  Because of this, it won’t be included in the new analytical report (though they could be purchased together, if you wanted).

Reason 3)  As we did deliver for the analytical component in the GRC2018, what we envisage for this new analytical report will go well beyond just performance of individual units, but will also:

3a)  Identify and explore collective performance in a number of ways that are significant to the energy transition; and

3b)  Focus specifically on the insights that can be gleaned:
i.  from detailed analysis of 22 years of historical NEM performance;
ii.  to inform the ongoing energy transition.

We’d invite you to provide your pre-order to GenInsights21 now, before it is released.

Generator Statistical Digest 2020


We repeated the GSD2019 process in January 2021 to produce the next annual update which:

(a)  We’re calling the Generator Statistical Digest 2020 ; and

(b)  Was completed on Wednesday 27th Jan 2021, with early access provided to those who pre-ordered their copies (saving $$ in the process) – and with broader release from Monday 1st February 2021.

As noted here, this use the same format as the prior GSD2019, but update for data to 31 December 2020, and include all new DUIDs (i.e. units) that entered the market through 2020.

We’d invite you to place your order today and we will:

(a)  provide you prompt access to your electronic PDF; and also

(b)  deliver you one bound hard copy (720 pages!) to the address you nominate

We look forward to hearing from you!

Generator Statistical Digest 2019


Given the success of our Generator Report Card 2018, we decided to follow-on from this by developing a partial update (and extension) in the form of a Generator Statistical Digest 2019 :

(a)  Utilizing 10 years of data to 31st December 2019; and

(b)  With a particular focus on calendar 2019 – adding in a new page for each DUID containing additional performance metric.

This was released on Tuesday 28th January 2020, with:

(a)  access provided immediately to those who had pre-ordered their copies; and

(b)  a wider notice was published on 13th February 2020.

On 8th June 2020 we published some ‘Feedback we have received about…’ the GSD2020.

Generator Report Card 2018


The Generator Report Card, covering 20 years of data to 31st December 2018, was released on 31st May 2019.

After a mammoth investment (of something like 10,000 hours) the Generator Report Card provided two core components of value:

Component #1 = approx 180 pages of analysis and insights, picking over some of the questions arising (particularly through 2017 and 2018) about various aspects of performance of our increasingly diverse fleet of generation assets.

Component #2 = approx 330 pages of statistics – one page for every DUID (unit) that operated in the 10-year period to 31st December 2018.  Using later terminology, this was our first Generator Statistical Digest embedded (as Part 3) within the Generator Report Card.

Following release on 31st May 2019 it received a swag of initial feedback (with other snippets tagged here), and the readership steadily grew in the many months following from the release of the Report.

Detailed review of summer 2012-13 in the QLD Region

Summer 2012-13 was a particularly volatile period in the Queensland region of the NEM – for a number of overlapping reasons. We fielded a number of calls through the summer from clients & other readers, asking us to help them understand what was happening.  A collection of articles were posted through the summer under this banner.

Given the complexities involved (and because the insights gleaned fed into the ongoing development of our ez2view software product) we conducted detailed analysis and prepared a detailed (3-volume) report.

You can learn more about it here.
