Case Study of 16:20 on 28th September 2016 (aggregate Raw Off-Target +894MW for Semi-Scheduled units)


With this 8th case study in this series, we come to the end of 2016 – and hence have covered the first 4 years (2013, 2014, 2015, 2016) of extremes in outcomes for Semi-Scheduled in the dispatch interval timeframe:

1)  We’re using the Aggregate Raw Off-Target measure, across all Semi-Scheduled plant, and have flagged all 98 dispatch intervals through until the end of 2019 where the result was in excess of 300MW (in either direction).

2)  We’re doing this given a push from the AER Issues Paper, but moreso inspired by the deliberations by the (now defunct) COAG Energy Council and (under threat?) ESB relating to ‘NEM 2.0’.

—————–

This particular dispatch interval needs no further discussion, as it was the dispatch interval encapsulating the start of the SA System Black event.

Hence I’m just going to post this summary table, highlighting the individual Raw Off-Target performance of all Semi-Scheduled units that were operational at the time, and leave it at that:
