We also had a 2 weeks long power outage 20 years ago. Again, in Quebec
Portland too had that major cold snap where power was out due to last mile transmission problems. I know at least one city in the metro area that sped up their plans to bury their power transmission because during that storm large parts of that city were without power for days.
There's the answer.
A public utility is a natural monopoly. If given lack of regulation (or, wrong/weak regulation) it will of course seek to maximize profit at all cost, which means very little is spent on grid quality and maintenance (these things eat into profits, thus bad).
Ever increasing profit.
As usual, socialism for the losses, capitalism for the profits.
It's all a massive scam. It would be better if companies were not able to own other companies.
