The plans are part of the province’s attempts to meet electricity demand with non-emitting sources, though in the short- to medium-term the province is also relying on more natural gas generation.

A report late last year by the Independent Electricity System Operator found that the province could fully eliminate natural gas from the electricity system by 2050, starting with a moratorium in 2027, but it will require about $400 billion in capital spending and more generation including new, large-scale nuclear plants.

The province launched consultations on that idea, and Smith says he heard a lot of support for new nuclear, in order to prepare for surging electricity demand in the 2030s from electric vehicles, new electric vehicle and battery manufacturing and electric arc furnaces for steelmaking.

“On a daily basis about 30 per cent of Ontario’s electricity comes from this site right now. There’s room alongside (units) Bruce A and Bruce B, potentially, for a Bruce C and that’s what this pre-development work is intended to begin today.”
