Hydro-Québec announced the commissioning of the new 735 kilovolt (kV) Micoua-Saguenay line which will contribute to the reliability of Quebec’s electricity transmission network. This new line will make it possible to meet the demand for electricity which will increase significantly in the coming years.
With a length of 262 km, this line connects the Micoua substation, located on the North Shore, to the Saguenay substation, in Saguenay–Lac-Saint-Jean. Construction took place from 2019 to 2023 and is the result of the efforts of more than 1,600 workers, nearly 25 per cent of whom come from host regions, including Indigenous communities. The cost of carrying out the project is $1,271 million.
The Micoua-Saguenay line project has generated major regional economic benefits. These were maximized by several initiatives and thus reached $81 million on the North Shore and $80 million in Saguenay–Lac-Saint-Jean. These amounts include regional contracts and regional subcontracting which affect a wide variety of sectors of the local economy.
“I would like to salute the dedication of our teams and our suppliers, as well as the collaboration of our partners and host communities. It is the contribution of everyone that allowed us to meet the many challenges of this project and to bring it to a successful conclusion. Our ability to work together, prioritizing health and safety, has allowed us to deliver a new 735 kV high voltage line which will ensure the robustness of our transmission network for years to come,” said Claudine Bouchard, vice-president, executive president and chief operating and infrastructure officer, Hydro-Québec.
As part of its Integrated Development Program, Hydro-Québec also invested $5.8 million in 25 projects chosen by the host communities.
