The Canadian power utility Hydro-Québec has commissioned its 735 kV Micoua-Saguenay power transmission line project that connects the Micoua substation on the Côte-Nord to the Saguenay substation in the Saguenay-Lac-Saint-Jean region (Quebec, Eastern Canada). Construction works of the 262 km transmission line took place from 2019 to 2023 and required an estimated investment of CAD1,271m (US$935m). The project is part of Hydro-Québec’s projects indicated in its 2035 Action Plan to meet increasing demand for electricity in the coming years.
In November 2023, Hydro-Québec released its “Action Plan 2035: Towards a Decarbonized and Prosperous Québec”, which sets its target to free up and add new assets to their current power generation capacity to meet up to 9 GW needed to supply the increasing demand growth by 2035. Related to the increase in capacity of the company’s power mix, Hydro-Québec also expects to ensure the reliability of the electric grid and to increase its reach by adding 5,000 km of new transmission lines to which it expects to make an investment of CAD50bn (US$36bn) by 2035.
