It also depends on the status of your local grid/substation. My university was on the same local distribution as a nearby hospital. The hospital had special status for receiving power, for obvious reasons. So in the 10 odd years I spent doing undergrad and post grad studies there was only ever 1 brief power outage during a thunderstorm. Meanwhile nearby suburbs probably averaged 2 power outages per year, typically for a few hours at most.
