Ontario Pumped Storage Hydropower Project

TC Energy is proposing to construct and operate a pumped storage hydropower facility located at the Department of National Defence's 4th Canadian Division Training Centre near Meaford, Ontario, on Nottawasaga Bay. As proposed, the project would store excess electricity from the grid by moving water from the bay to a reservoir, that would then be released back to the bay to generate electricity during periods of demand. It will have a production capacity of 1000 megawatts and will operate indefinitely.
