It is really interesting for me to hear your experience.

I have lived in Norway all of my >45 years on this earth and I can say that in the first half of my life were I lived on the west coast, power outages was totally expected.

We had a generator, and we had a gas stove ("everyone" in Norway use electricity for cooking) for those days, a kerose lamp and a wood stove.

The longest power outage I experienced was 3 days, somewhere around 1986 I think, but a few hours could happen multiple times and overnight outages were not unusual.
