I keep hearing about natural gas and on-site power for these data centres. I'll believe it when I see it.

There are already have a couple in Calgary and they're hooked directly to the grid. The cost of electricity for the city shot up at the same time. Also, there have been a few brownouts caused by them not being ready to handle late night draws from those data centres.

That's at least what I'm seeing. Though, admittedly, it's from older project articles. Maybe something has changed in recent months?
