Rebuilding of the 69‑kV transmission line between Cap‑aux‑Meules and Grosse‑Île
Project overview
To ensure the sustainability of its power transmission system in Îles‑de‑la‑Madeleine, Hydro‑Québec wishes to rebuild the 69‑kilovolt (kV) line linking Cap‑aux‑Meules and Grosse‑Île substations, which was commissioned in 1980.
The rebuilding will secure the supply of electricity to the archipelago with a new line designed to meet current standards that takes into account the specific environmental conditions of the region, such as high winds, freezing rain, salt air and shoreline erosion.
Hydro-Quebec is currently at the draft-design stage, which consists of analyzing the various possible scenarios for the reconstruction.
