It’s not just power - we had a forest fire one year that burned a microwave tower & killed our cell phones _and_ internet for a week. The local businesses struggled for a day or two, because no one really carries cash anymore.
I should add that kind of like the OP, I added an enphase LiFePO4 house battery and panels. They’ll keep critical loads running basically indefinitely, which has been a welcome change. We have gas heat, but I used to get nervous in the winter when the power went out (our boiler requires electricity to run).
I'm worse off than many, because I live on an island, and my electric service comes in across the water from a penisula. There's an awful lot of non-redundant paths through the penisula. On the island, there is no redundancy either, but there is a plan to create a ring between the three substations, which should help.
Most of my outages are only a few seconds. At the substation, they have reclosers [1], circuit breakers that will open when shorts or abnormal currents are detected, and then quickly reclose (thus the name) as many shorts are transient.
But when a tree falls on the line, that needs a truck rolled out to investigate, and often another one or two to repair. And conditions are similar across the area, so if one tree is on a line, there will be many. My local infrastructure is low priority because it serves few customers.
Ice storms are pretty nasty too, because then you've got potentially a lot more trees falling, and also hazardous road conditions that prevent or slow repair work.
When I lived in other places, power outages were much more rare. I would have never considered a whole house generator in those places, but I have one here and most of the houses I looked at had them. I would certainly install one if there wasn't one already.
