> Power outages are a normal thing and can happen at any time I cannot recall a single power outage in my home city that lasted longer than ~three hours. And even those "couple hours" outages are extremely rare, much less than once a year I would wager. According to the statistics, the expected unavailability in my country is around 0.002 - 0.003 %. That's hardly something I would describe as a "normal thing" that "can happen at any time". That's a really rare thing. The "SAIDI" value here is under 15 minutes. Meanwhile the median SAIDI of the US is ~1.5 hours. That still doesn't sound like a common thing.
