Really interesting data, particularly when you compare the very low level of outages in Canada/UK compared with the US.
At least here (Canada), utils push all of their costs to end-users & IIUC have an incentive to have high capex/low opex networks because of regulated return.
As a Canadian residential electrical customer, we pay a lot in base fees from what I hear relative to US customers. Sure it's more reliable, but tbh, it's not worth spending much to get 5 9s (5 mins of downtime a year) vs 4 9s (50 minutes/yr). Heck, even 500 minutes/yr would be fine for me.
But commercial/industrial users won't feel the same way, and managed to successfully spread the cost of adding 9s among users that largely don't care.
Ontario's Energy Board has a dashboard (https://app.powerbi.com/view?r=eyJrIjoiNmY1YjU0NmUtMTJhYi00N...) that says in 2023, total average outage time was ~5hrs (and that's somewhat typical of the last 10ish years).
Hydro Quebec says that in 2023 (https://www.hydroquebec.com/data/documents-donnees/pdf/hqd-0... FR sorry) the average downtime was ~4.5 hours.
