Dismantling transmission lines

Thanks to the commissioning of new transformer substations (Duchesnay, Limoilou and Baie-Saint-Paul) in the Capitale-Nationale region, a number of power transmission lines can now be dismantled.

Dismantling work will begin in fall 2017 and end in spring 2018 with site restoration. A total of 1,944 structures (steel towers and wooden H-frames or poles) will be removed in the region. No service interruption is anticipated during the work.

Dismantled equipment (conductors, steel, and insulators) will be sent to specialized recycling sites.

The work will be done by a specialized contractor and supervised by Hydro-Québec. Whenever possible, work will be carried out within the hours set forth in municipal bylaws.
