The main point for the power from the La Grande dams is to feed the data centres. It's the data centres that consume a lot of energy because of the size of these data centres. It doesn't take too many data centres to consume 200 megawatts, even though we have all the natural cooling systems in the north, which reduce the cost of operating data centres. I visited data centres in Silicon Valley, and their main issue is the cost of cooling their computers.
