I am no expert but remembering the grid outage in Spain this year, which was caused by a substation or node failure and not by a capacity problem. Wouldn't it be fair to describe resiliency as a combination of both capacity and nodes?

The Spainout was caused by having too little rotating mass in the grid that stabilizes the frequency.

There was a trigger in some of the PV systems, but that wasn't the underlying cause.

Yes, interconnectedness is critical if you want reliability.

Spain has far too little transnational capacities. That was a significant contributing factor in the grid outage.

If you want to change the topic of this conversation to distribution resiliency instead of production resiliency then sure.

I had both of these as a single concept in my head, thus the confusion.
