LATE LAST SUMMER, with the Paris climate conference looming, United States President Barack Obama unveiled an ambitious effort by the Environmental Protection Agency that could provide Canadian hydro power producers with the kind of growth potential not seen in decades.

The reason? Seven years after the EPA decreed that greenhouse gases pose a threat to human health and would be regulated under the Clean Air Act, Obama’s Clean Power Plan laid out a strategy to push state governments to implement a major shift in power generation, away from dirty fossil fuels, especially coal, to cleaner sources such as natural gas and renewables (including wind and hydro imported from north of the 49th).

Power exports are nothing new for Canada’s electrical utilities. Canada’s hydro sector each year ships about 40 terawatt-hours, or just more than a tenth of our overall production, south to the United States. While Canada’s net electricity exports to the U.S. have been rising over the past decade (mostly from Quebec and Ontario), they account for less than two per cent of total U.S. consumption, says Jacob Irving, CEO of the Canadian Hydropower Association. In the post-Paris Agreement era, he argues, America “is where the huge opportunity lies.”

Herewith, a survey of Canada’s water energy present — and its potential future.
