Dan’s already noted here about how (on Thursday 1st December) the AEMO released its ‘Engineering Roadmap to 100% Renewables’ report.
In my current process of catching up on all that’s been happening in the past couple weeks, I’ve seen a number of references to it externally … but no time to note them.
Lesser noted (at least from what I have seen) is the series of 3 x Reports the AEMO also released on 1st December 2022 relating to System Security Planning. There’s further details on this page on the AEMO website here, but I thought it useful to lift out the map AEMO included in this infographic:
… and I also wanted to provide a direct reference to these three reports that speak with the different coloured circles on the map above:
| 2022 System Strength Report | 2022 Inertia Report | 2022 NSCAS Report |
|---|---|---|

In his speech at MEI’s Annual Symposium on 9th December, Daniel Westerman noted: ‘… system strength is the ability of the power system to maintain a stable voltage waveform at any given location, both during steady state operation and following a disturbance.’ The report is here:
Daniel then went on to note: ‘It’s a bit like securing a beach towel on the sand on a windy day by anchoring it with a number of rocks in various places. The challenge is where to put those rocks, and how heavy they need to be to stop the beach towel flapping too much.’ |
In the same speech, Daniel Westerman also noted: ‘Most people will know that inertia is the power systems ability to maintain steady electrical frequency, at 50 hertz, even during disturbances.’ The report is here:

The third report is here:

These three services were some of the services we had in mind when we coined the term ‘Keeping the Lights on Services’ as a layperson’s umbrella name used to describe all of the services a functioning grid requires but is not being supplied by the ‘Anytime/Anywhere Energy’ that’s emerged as its own category as a result of ‘The Schism’:
1) Which we introduced in the GRC2018; and
2) Which was further expanded on in GenInsights21 several years later.
As such, we’ll review these reports with interest.
For others who are interested, the AEMO’s running a webinar about these reports this Thursday 15th December 13:00-14:30 AEST via Teams. Interested parties can register their interest in attending with the AEMO here.
