For sure. 

And probably a good thing to aim for _some_ level of self sufficiency in terms of energy generation.

The last note is interesting. Sometimes I wonder if solar is just a technology that's better suited for decentralized usage like that, at least in most current instances.

How Did Spain’s Electricity Grid Collapse? (Financial Times)

In a sense, I hope it's the renewables. Probably not for the same reasons most coal and gas fanboys do, though~~

This will be the perfect opportunity to improve the network's ability to respond to the unpredictability of renewables. In the long run, this will be beneficial for the future of renewables. Gotta stress-test it...

As for the premise of your article, I don't think we'll know for sure any time soon. And when I say "we", I mean the public, the plebs. Depending on the actual cause, some people might have reason to keep some level of secrecy.

EDIT: Paradoxically, my sister in Madrid was thankful to have her own solar panels as this is what gave them electricity during the blackout~~
