Hydro-Québec PUBLIC CONSULTATION Winter 2018-2019 Strengthening the 315-kV Transmission System in Abitibi-Témiscamingue Significant economic growth is expected in the Abitibi-Témiscamingue region in the coming years, with an accompanying increase in electricity demand. Hydro-Québec studies show that the capacity of the 315-kV and 120-kV systems in this region must be increased to meet the anticipated development needs. Hydro-Québec is therefore planning to build a new 315-kV double-circuit line about 150 km long between Lebel substation and a new 315/120 kV substation to be built in the Abitibi-Ouest regional county municipality (MRC). The new substation will be connected on the south side to the existing 120-kV line. The new facilities will make it possible to: • support development in Abitibi-Témiscamingue • strengthen the region’s 120-kV and 315-kV systems • supply clean, reliable, renewable and sustainable energy. Environmental and technical studies Study area Over the course of 2018, Hydro-Québec inventoried a study area of about 895 km2. As a result, we now have a better understanding of the project’s host environment. The study area excluded most urbanization perimeters as well as concentrations of cropland and private land. In addition, the vast majority of existing and planned protected areas were also excluded. The next step was to develop line routes and examine possible substation sites based on the following criteria: For the substation and the 315-kV line • As much as possible, avoid the most sensitive components—farmland, wetlands, bodies of water, protected areas, the built environment and vacation areas • Minimize the impact on the landscape For the substation • Avoid eskers • Give preference to sites behind a visual screen For the line • Run the line along existing lines whenever possible • Select the shortest route possible to minimize the number of components that could potentially be impacted Hydro-Québec will continue the inventory over the course of 2019, examining study area geomorphology, hydrography, land use, vegetation, wildlife and archeology, among other things. The municipality of Authier 2 Proposed substation site Since the beginning of the project, a number of different sites have been considered for the substation. Technical studies have demonstrated, however, that only one site meets the main siting criteria: accessible by road, suitable soil characteristics, and proximity to an existing 120-kV transmission line. The site selected for the new substation is along highway 111, also called Chemin des Pionniers at this location. It is about 8 km south of the village centre of the municipality of Authier.
