I lived in a state that had regular grid outages, it sucked. They were almost always rolling blackouts in the summer, so we at least knew roughly how long it would last.
It's odd that my electricity in California cost around 45 cents a kwh and was sometimes shut off during the summer. Now I pay around 8 cents a kwh and it's been off twice in the last 18 months for short periods. You'd think at over 5 times the cost the service would be a bit better.
About the quality of life rating. I'd use income required to support a family of four, access to healthcare, crime, homeless per capita, education. Not necessarily in that order.
