I think it's ENTSO-E, here's their most recent report into an incident on 21 June 2024: https://www.entsoe.eu/publications/system-operations-reports...

For that incident, an expert panel was set up in July, the interim report was published in November, and the final report in Feburary 2025: so it'll take a few months.

BBC reporting the head of Spain's electricity grid saying restoring power could take "between six and ten hours": https://www.bbc.co.uk/news/live/c9wpq8xrvd9t?post=asset%3A85...

Interesting, but in terms of load I think think the data may just be delayed by ~1 hour. Switching to UTC, to avoid timezone confusion, it's currently 13:10:

Last actual load value for Spain at 12:15: https://transparency.entsoe.eu/load-domain/r2/totalLoadR2/sh...

Last actual load value for France at 12:00: https://transparency.entsoe.eu/load-domain/r2/totalLoadR2/sh...

It seems Spain lost 15GW of load, but is still running 10GW of load: https://transparency.entsoe.eu/load-domain/r2/totalLoadR2/sh...

Would this suggest the grid hasn't snapped apart, or is it just not possible to tell from the data?

Coal, pumped hydro, and nuclear generation all went to 0 around the same time, but presumably that's those sources being disconnected from the grid to balance demand? https://transparency.entsoe.eu/generation/r2/actualGeneratio...

The best source for data seems to be the European grid operator themselves: https://transparency.entsoe.eu/dashboard/show

Spain's demand: https://transparency.entsoe.eu/load-domain/r2/totalLoadR2/sh...

Spain's generation: https://transparency.entsoe.eu/generation/r2/actualGeneratio...

Spain's import/export with France: https://transparency.entsoe.eu/transmission-domain/physicalF...

The filters can be used to see similar data for Portugal

Spain loses around 15GW of demand at the same time: https://transparency.entsoe.eu/load-domain/r2/totalLoadR2/sh...

I don't think we're able to tell from the data if one is the cause of the other, are we? Since if production was lost, load would have to be shedded to balance the grid, and if load was lost (e.g. due to a transmission failure), production would have to be disconnected to balance the grid.

Yes, France was importing 884MW from Spain at 12:45, 198MW at 13:00, no net flow at 13:15, and Spain has been importing up to 265MW since: https://transparency.entsoe.eu/transmission-domain/physicalF...
