Four divisions

Hydro-Québec generates, transmits and distributes electricity. The company has four divisions.

Hydro-Québec Production generates power to supply the Québec market and sells power on wholesale markets. Water is used to generate over 99% of its output. The division must provide Hydro-Québec Distribution with a base volume of up to 165 TWh of heritage pool electricity annually.

Hydro-Québec TransÉnergie operates the most extensive transmission system in North America to serve its customers inside and outside Québec. It markets system capacity and manages power flows throughout Québec. The division also ensures the development, reliability and long-term operability of its system. Its Direction – Contrôle des mouvements d’énergie acts as Reliability Coordinator for transmission systems in Québec. The operations of Hydro-Québec TransÉnergie are regulated by the Régie de l’énergie, an agency responsible for regulatory supervision of the transmission and distribution of electric power.

Hydro-Québec Distribution provides Quebecers with a reliable supply of electricity. To meet needs beyond the annual heritage pool of 165 TWh, which Hydro-Québec Production is obligated to supply, it buys power on open markets. The division also encourages customers to make efficient use of electricity and is responsible for customer relations. The operations of Hydro-Québec Distribution are regulated by the Régie de l’énergie.

Hydro-Québec Équipement et services partagés and Société d’énergie de la Baie James (SEBJ), a subsidiary of Hydro-Québec, design, build and refurbish generating and transmission facilities, mainly for Hydro-Québec Production and Hydro-Québec TransÉnergie. Furthermore, through the Centre des services partagés, the division offers a broad range of company-wide shared services, including procurement, real estate management, vehicle fleet management, materials management, as well as management of food, accommodation and air transportation services.

Other activities

Through its subsidiaries, Hydro-Québec works with a number of other players in the field of energy and technological innovation. For example, one of the company’s main subsidiaries, Hydro-Québec IndusTech, is responsible for TM4 Inc., a leader in the field of electric powertrain systems.

In addition, Hydro-Québec can count on its research institute (IREQ) in all of its activities. IREQ employs about 500 people and has obtained some 1,100 patents since it was founded and published thousands of articles. Hydro-Québec also works with many international partners under 250 signed agreements.
