Hydroelectricity uses the energy of moving water to spin turbines — the backbone of Canadian electricity and the reason our grid is already ~70% emission-free.
Flowing or falling water is directed through turbines connected to generators. Dams and run-of-river facilities convert gravitational energy into a steady, controllable supply of clean power that can ramp up in minutes when demand spikes.
A single large station can power hundreds of thousands of homes — Churchill Falls and the La Grande complex rank among the largest power stations on Earth. Quebec, BC, Manitoba and Newfoundland & Labrador all run grids that are 87–99% hydro.
Hydro demands major up-front construction, but the fuel is free and stations routinely operate for 50–100 years — producing some of the lowest lifetime costs per kWh of any source, which is why Quebec and Manitoba enjoy Canada's cheapest power.
Because hydro output is dispatchable, reservoirs act like giant batteries — storing water when wind and sun are abundant, releasing it when they're not. Canada's hydro fleet is the balancing engine of the renewable transition.
Canada is the world's third-largest hydroelectricity producer — moving water generates about 60% of all Canadian electricity.
Output adjusts in minutes to match demand — rare among renewables.
Stations serve for generations with proper maintenance.
Reservoirs balance variable wind and solar like a giant battery.
