In this appendix we take a look at a number of different ‘heartbeat’ metrics that help to identify the overall health of the NEM, including:

1)  Weather factors (like temperature)

2)  Prices

3)  System inertia

4)  Frequency Performance

5)  Instantaneous Reserve Plant Margin (IRPM) … new for this Q3 update

… and others.

15 pages

In this appendix we take a look at the changing nature of Grid Demand, which necessitates looking into:

1)  Grid Demand

2)  Rooftop PV

3)  Underlying Demand

… and also Market Demand.

43 pages

In this appendix we take a look at different aspects of the performance of Wind and Large Solar assets (separately and together), including:

1)  Production

2)  Commercial Performance

3)  Curtailment

4)  Self-Forecasting

5)  ‘Forecast Convergence‘ for VRE Capability

6)  Aggregate Raw Off-Target

… and more.

26 pages

In this appendix we take a look at different aspects of the performance of (fully) Scheduled assets (at various levels of bundling), including:

1)  Performance specifically through Q3

2)  Aggregate Scheduled Target (AggSchedTarget):

(a)  In absolute terms

(b)  Ramping from one Dispatch Interval to the next

3) ‘Forecast Convergence‘ for AggSchedTarget

31 pages

The 47 x coal units still operational in the NEM in this quarter are a special subset of dispatchable plant that have been addressed in more detail in this particular Appendix – because:
1)  They still provide a large share of the Energy consumed in the NEM (and also the ‘Keeping the Lights on Services’);
2)  But suffer from the big drawback of high emissions intensity.

What this contains includes:

1)  Performance specifically through Q3

2)  Changing levels of Unavailability

3)  Three different metrics that help to indicate the changing rate of ‘Sudden Failure’

4)  Categorisation of Outages through Q3 into Planned and Forced

5)  ‘Forecast Convergence‘ for Aggregate Coal Unit Availability across the 47 units operational in this quarter.

22 pages

In this Appendix, we look at:

1)  Inter-regional interconnectors (flow and congestion, etc)

2)  Marginal Loss Factors.

… and in future Editions will add in other aspects.

Five Minute Settlement commenced on 1st October 2021 (i.e. twelve months before the end of Q3 2022), so it was a nice milestone from which to look back on the 12 months that has elapsed to see what was visible in the data, in terms of how the NEM has evolved.
