I dunno, I’m guessing really, but having experienced power cuts routinely in other countries, everyone had a means of getting by. It’s just what you had to do.
The power cuts are not “routine” in this area. So to spend a few thousand on a genset and connections to your household electricals, seems a bit much for something that happens every 20 years or so. Plus ongoing maintenance. If it was routine I probably would.
I had plenty of torches and bike lights during the power cut, it was less than 24hrs for me.
We had heating from the log burner but no way of making a brew. My old camping stove wouldn’t work. Cooked on a disposal BBQ.
I have since spent £20 on a new stove and gas. Also bought a electric lantern.
I know a lot of people in the village that only have electric storage heating and they froze for several days, until full power was restored.
