Romaine-2–Arnaud Line.

A 1,550-MW hydroelectric complex is being built on the Rivière Romaine. Separate draft-design studies and applications for authorizations were carried out for the current project, which concerns the structures required to integrate the output of the four generating stations into the power system.

The project includes:

  • building some 500 km of transmission lines, designed for 315-kV and 735-kV but operated at 315-kV
  • building new switchyards at the generating stations
  • modifying and adding equipment in existing facilities

Hydro-Québec began its work in summer 2011.
