Your question is very pertinent. To answer, we need to go back a few years.
In 1997, the electricity market in North America opened its doors to competition. Hydro-Québec therefore decided to create Hydro-Québec TransÉnergie and to give the entire North American market access to its transmission system. The new division's mandate was to offer non-discriminatory access to Québec's transmission system to offer all its customers reliable, high-quality power transmission. Following this change, regulatory organizations authorized Hydro-Québec to buy and sell electricity on neighboring markets.
The U.S. Federal Energy Regulatory Commission (FERC) granted Hydro-Québec a licence to sell wholesale electricity on the U.S. market. This authorization enabled Hydro-Québec to expand its market, capitalize on business opportunities outside Québec and contribute even more to Quebecers’ collective prosperity.
Following the adoption of the Act to amend the Act respecting the Régie de l'énergie in 2000, the company confirmed the unbundling of its electricity distribution, generation and transmission business units. Two new divisions, Hydro-Québec Production and Hydro-Québec Distribution, then joined Hydro-Québec’s TransÉnergie division. Finally, the Hydro-Québec Équipement division was created in June 2002 and its official name is now Hydro-Québec Équipement et services partagés.
