With a view over our shoulder for the release of more ‘official’ analysis (perhaps coming soon?), we’ve continued to explore the nearly identical frequency glitches experienced over three weeks ago now:
- Progressively explored here pertaining to (10:30 on) Friday 10th April 2026; and
- Progressively explored here with respect to (14:20 on) Saturday 11th April 2026.
This article today will be one of a number of short articles, targeting particular pieces of data or understanding that we’re accumulating.
In this article we wanted to start with this unbundled listing of 402 discrete stories about the performance of Semi-Scheduled units (115 solar and 86 wind) units across the two similar frequency spikes a day apart …
| Event | The stories of 115 x Semi-Scheduled
Solar Farms |
The stories of 86 x Semi-Scheduled Wind Farms |
|---|---|---|
Friday 10th April 2026 The Frequency peaked at 50.174Hz (just above the NOFB) at 10:30:41.5 i.e. just on the other side of the 10:30 dispatch interval |
Here’s all 115 x Solar Farms listed alphabetically by DUID, with 5 dispatch intervals shown for each, straddling the frequency spike in the middle dispatch interval:
Readers can click on the image to open a larger-resolution view in a separate tab Note that the MULWASF1 unit is listed (because it was registered when this data was extracted), but there’s no data for it (because it’s not operational). At this point in time, we’d just like to highlight the aggregate Dispatch Error calculated across all of these units for the 5 dispatch intervals shown:
That’s all, for now… |
Here’s all 86 x Solar Farms listed listed alphabetically by DUID, with 5 dispatch intervals shown for each, straddling the frequency spike in the middle dispatch interval:
Readers can click on the image to open a larger-resolution view in a separate tab Note that the WAMBOWF2 unit is listed (because it was registered when this data was extracted), but there’s no data for it (because wasn’t operational till 2nd May). At this point in time, we’d just like to highlight the aggregate Dispatch Error calculated across all of these units for the 5 dispatch intervals shown:

Saturday 11th April 2026 The Frequency peaked at 50.176Hz (just above the NOFB) at 14:20:34.3 i.e. just on the other side of the 14:20 dispatch interval |

Now, obviously there are so many individual stories that it’s easy for readers to ‘not see the woods for the trees’, so in a follow-on article we’ll organise these stories into a few high-level chapters:
1) With:
(a) one key chapter following on from this big clue that was subsequently noted in this sequence of events.
(b) but there appearing to be other chapters worth exploring, as well.
2) So stay tuned… [ARTICLE LINK TO COME]
