Norway is almost entirely hydroelectric, which is pretty close to ideal in terms of providing reliable non-fossil-fuel power - and unfortunately something most countries don't have the geography to pull off, which is why Norway ended up so much more electricity-centric. I think they also accept the odd multi-day outage affecting small numbers of customers like everywhere else, especially in urban areas, just because weather gets in the way of providing 100% reliable power. Also, remember larger-scale outages are long-tail events which means it's not really possible to measure exactly how likely they are especially with a small country like Norway.
