Ontario electricity demand to soar due to EV manufacturing and AI: system operator [Video]

Demand for electricity in Ontario is set to soar by 75 per cent in the next couple of decades, far higher than was projected just last year, in part due to a sudden surge in data centres supporting artificial intelligence, the system operator said Wednesday.

The demand has been relatively flat for the past 20 years, but now it is building and shows no signs of levelling off, officials with the Independent Electricity System Operator said in a briefing. Just last year, they expected demand to grow 60 per cent higher by 2050.
