Now I'm curious about what's in the confidential version of the report.

Based on the redacted bits, it is mostly company names and locations.

And more interestingly, the specific reasons various installations were unable to start up as they should have:

> Incidents detected during equipment start-up - Firstly, there is information consistent with the fact that several installations with the obligation of autonomous start-up were finally unable to provide this service in a stable manner, joining the system only once voltage had arrived from outside (from another of the "islands", normally anchored in one of the interconnections). This slowed down the start-up of the "skeleton" of the electricity system that would later make it possible to replenish the supply to demand.

The rest of the ~2 pages in that section is redacted.
