Reinforcing Bécancour’s 230‑kV transmission grid

Overview Increasing capacity at Nicolet and Bécancour substations

Hydro‑Québec is working to reinforce its 230‑kV transmission system located between Nicolet substation in Sainte‑Eulalie and Bécancour substation in Bécancour.

To this end, we are replacing and adding equipment in the two substations and building a new 230‑kV line segment, approximately 1.3‑km long, south of Bécancour substation.

Location of substations and selected route

Based on stakeholder recommendations and a preliminary analysis of technical, human, and environmental constraints, Hydro‑Québec selected the following route as the option with the least impact.

Other work

Connecting industrial customers

Hydro‑Québec has completed projects to connect industrial customers to the existing 230‑kV system. All of these connections, covering short distances, were carried out within the boundaries of the Bécancour industrial park and port.

Increasing capacity at Cournoyer substation

We increased the transformer capacity at the 120/25‑kV Cournoyer substation with the addition of a third transformer. We also upgraded the substation’s automatic control systems.
