Hydro-Québec Electricity Transmission System

Electrical Engineering

Hydro-Quebec operates an international electric power transmission system centered in Quebec, Canada. The system pioneered the use of very high voltage 735-kilovolt alternating-current power lines, which link the population centers of Montreal and Quebec City to distant hydroelectric power stations, including the Daniel-Johnson Dam and the James Bay Project in northwestern Quebec, as well as the Churchill Falls Generating Station in Labrador.
