Excellent question, which refers to the one you previously asked.
Unbundling, or functional separation, makes Hydro-Québec Production and Hydro-Québec Distribution two independent entities. Hydro-Québec Distribution’s activities are regulated by the Régie de l’énergie, which ensures that consumers pay a fair rate. Hydro-Québec Production’s activities, on the other hand, are not regulated. Thanks to its very profitable exports, Hydro-Québec Production’s revenues contribute to the company’s net income, 75% of which is paid to the government to finance public services.
