What is Hydro-Québec?

Hydro-Québec is the provincial Crown corporation responsible for the generation, transmission, and distribution of electricity in Quebec. Established by the Quebec government on April 14, 1944 under Premier Adélard Godbout, the corporation was massively expanded by Premier Jean Lesage's nationalisation of the province's private electricity producers on May 1, 1963 under Natural Resources Minister René Lévesque. The 'Maîtres chez nous' (Masters in our own house) campaign that drove nationalisation is a defining moment of Quebec's Quiet Revolution.

Hydro-Québec is the largest hydroelectric utility in North America and one of the largest in the world. The corporation operates 60 hydroelectric generating stations and one nuclear plant (Gentilly-2, decommissioned 2012), with total installed capacity of about 37,000 megawatts. The James Bay region's La Grande complex, including the 5,616-megawatt Robert-Bourassa station (formerly La Grande-2), is the centrepiece of the system and one of the largest hydroelectric complexes in the world. Construction of the James Bay project from 1971 to 1996 reshaped Quebec's economy and Indigenous-government relations through the 1975 James Bay and Northern Quebec Agreement.

Quebec's electricity rates are among the lowest in North America, with residential rates of about 7 cents per kilowatt-hour and industrial rates of about 4 cents per kilowatt-hour, contributing significantly to the province's competitive advantage in aluminum smelting, paper milling, and increasingly in data centres and battery manufacturing. Hydro-Québec exports about 30 to 40 terawatt-hours of electricity per year to the United States and neighbouring provinces, generating about $3 billion in net export revenue. The Champlain Hudson Power Express, scheduled to start delivering Quebec power to New York City in 2026, is a $6 billion underground transmission line.

Hydro-Québec returns dividends of about $4 to 5 billion per year to the Quebec government, the largest single source of provincial revenue after personal income tax. Net assets exceed $90 billion. The corporation's research arm, the Hydro-Québec Research Institute (IREQ), has developed advanced battery technologies including lithium-iron-phosphate cells now licensed worldwide. Hydro-Québec's $185 billion 2035 Strategic Plan commits to expanding wind, additional hydropower, and battery storage to support Quebec's decarbonisation.
