This came up in a recent discussion.  It was mentioned that during power
failures (as during severe weather) human intervention is needed on some
trunks ; for humans to climb on poles it is necessary that some
electricity feeders are cut, which is conceptually similar to a data
link going down.

And, in the same vein, electricity must arrive at the destination via
other ways than the typical trunks.  How is this path set up?

The growing importance of this problem relates to the growing number of
electricity suppliers.

I guess routing algorithms as we know them in link-state/etc can deal
with it in a scalable manner.
