Tristan Edis from Green Energy Markets takes a deep dive into generator performance across the NEM. He provides his take on which wind and solar farms have outperformed and underperformed, through the recent renewable investment boom.

In Part 2 of this Case Study, we look at those 15 x Semi-Scheduled units highlighted with large deviations (mostly under-performance) at 17:05 on 27th October 2022 in order to understand more.
This 18th Case Study in the series investigates two separate dispatch intervals showing extreme collective under-performance across all Semi-Scheduled units on Monday 25th March 2019.
This 15th Case Study is longer than the earlier 14 as it deals with 4 discrete instances of extreme level of collective under-performance, and 1 instance of over-performance, all within a 4-hour timeframe on the same day. A day which appears to have had widespread weather activity affecting the output of BOTH Wind and Solar across 3 Regions. A challenging day!
This is the 11th Case Study in a series (looking at extreme outcomes of Aggregate Raw Off-Target for Semi-Sched units). We’ve rolled into 2018, now and (coincidence?) this one is much more complex than the first 10 from the earlier years …
This 9th case study in this series advances us into October 2017, where we see another example of an extreme outcome for collective under-performance. Most notably this happens across 5 Wind Farms (with one unit completely tripping).
