Looking back at Tuesday 13th February 2024 there’s consistently large aggregate under-performance (compared to Target) across all Semi-Scheduled units in the NEM through daylight hours. The reason for the increased procurement of Regulation Raise.
Another short article today presenting an overview of Aggregate Raw Off-Target (AggROT) for Semi-Scheduled units on 16th February 2021 (the largest incidence of collective over-performance at that time).
Another short article today (from GenInsights Quarterly Update for Q3 2022) presenting an overview of Aggregate Raw Off-Target (AggROT) for Semi-Scheduled units on 23rd August 2022.
Another short article today (also from GenInsights Quarterly Update for Q1 2023) presenting an overview of Aggregate Raw Off-Target (AggROT) for Semi-Scheduled units on Friday 20th January 2023.
A short article today (whilst in the midst of finalising GenInsights Quarterly Update for Q1 2023) presenting an overview of Aggregate Raw Off-Target (AggROT) for Semi-Scheduled units on Friday 3rd February 2023.
In the fourth instalment of this ongoing case study, Dan Lee maps the locations and contributions of the semi-scheduled units that contributed to the +861MW Aggregate Raw Off-Target that occurred on the afternoon of October 27th 2022.
In Part 3 of this Case Study, we look at the source of the Dispatch Interval Availability forecasts for these units at 17:05 on 27th October 2022 (i.e. Self-Forecast or something else, incl AWEFS/ASEFS).
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.
In Part 1 of this Case Study, we start to look at the large collective under-performance across all Semi-Scheduled units (i.e. Wind and Large Solar) at 17:05 on 27th October 2022. More to come in subsequent parts…
In today’s article (a third snippet from GenInsights Quarterly Update for Q4 2022) we take a look at levels of large ‘Aggregate Raw Off-Target’ (i.e. large collective deviations away from Target), which continue to grow for the Semi-Scheduled category and remind us of that question …
Allan O’Neil provides an explainer about how small deviations in supply and demand are managed in the NEM, in order to help us understand the apparent swings in frequency that we noted in QLD last Friday.
Following from the release of GenInsights21, in this article we look at some of what that analytical publication can help us understand, in terms of how the changing market is impacting on the role that renewables will increasingly play in the NEM in the years to come.
