120/25-kV Bonsecours Substation and 120-kV Supply Line Conversion of the 49-kV System in Estrie GENERAL INFORMATION • SPRING – SUMMER 2018 Current situation Recommended solution The project area is currently supplied Hydro-Québec TransÉnergie’s recommended solution by a 49-kilovolt (kV) system that was is to build a new 120/25-kV substation between built by the Southern Canada Power the Lawrenceville and Valcourt substations, and Company in the 1940s. Due to growth connect it to the grid with a 120-kV line. This new in the region’s electricity demand, line, approximately 20 km long, will connect the this system has reached its maximum new substation to Stukely substation in Stukely-Sud. capacity. The 49-kV Lawrenceville and Valcourt substations, Hydro-Québec must increase the as well as some sections of the 49-kV lines, will then system’s capacity to meet the be dismantled. region’s future requirements. This project is part of the plan The project will also require: to convert Estrie’s 49-kV system, • Additions and changes to the distribution system which began with the 2016 to connect local customers to the new substation, commissioning of the new including the conversion of the 25-kV facilities 120/25-kV Adamsville substation belonging to BRP (Bombardier Recreational Products) in Bromont. • Related work at Stukely substation • Reconstruction of an existing line in the regional county municipalities (MRCs) of Brome-Missisquoi and La Haute-Yamaska (the 120-kV Cleveland– Waterloo line). Study area The study area covers 143 km2 and includes five municipalities in the MRC of Val-Saint-François—Valcourt, Canton de Valcourt, Lawrenceville, Bonsecours and Sainte-Anne-de-la-Rochelle—as well as Stukely-Sud and Eastman, two municipalities in the MRC of Memphrémagog. The study area was selected to encompass all the elements from the biophysical environment, human environment and landscape that are likely to be affected by the project. Technical and environmental studies In the coming months, Hydro-Québec will conduct technical studies and detailed environmental inventories to identify the project’s characteristics and obtain an in-depth understanding of the host environment. Once these studies are completed, the project team will be able to identify potential substation locations and route variants that will be presented to the public. These locations and routes will be subject to comparative analyses based on environmental, technical and economic criteria. From the beginning, and at every step of these studies, Hydro-Québec will take the community’s concerns into account to determine the line route and location with the least impact. 2 72°25' 72°20' 72°15' ProjeRci t component viè Maricourt, re Study area M Brandy No ire R Substations and power transmission lines iv iè Roxton, CT r # e 49 kV u a # se 243 49 kV (private substation) is N u o 222 R # i r 120 kV e ' 0 3 ' ° 0 Boundaries 5 3 4 ° Valcourt, V 5 222 4 Regional county municipality (MRC) Municipality # 533 # # Bombardier Produits rd a Saint- g Récréatifs inc. substation re Valcourt substation Racine, M Joachim-de- u a e (to be dismantled) Shefford, M B a eau d Ruiss LE VAL- n ACTON e Valcourt, CT B SAINT-FRANÇOIS (MRC) u (MRC) a e s s i u Béthanie, M R LA HAUTE- YAMASKA (MRC) Lawrenceville, VL Lac des Français # Lawrenceville substation (to be dismantled) ' Lac 5 2 ' ° 5 243 Bowker 5 2 4 ° 5 4 R Bonsecours, M i 4 v i 2 è 5 r e e ir o R N o Sainte-Anne- u g de-la-Rochelle, M e e r è i v i R Orford, CT Lac T Stukely C , d r o f f e MEMPHRÉMAGOG h Stukely- S (MRC) Sud, VL Lac Parc ' 0 Brousseau 2 ' national du Lac ° 0 5 2 Mont-Orford 4 ° Parker 5 4 112 Stukely Eastman, M substation 1388 1192 # 0 1.1 2.2 km 540 MTM, zone 8, NAD83 (SCRS) File: 7576_bu_slq_001_180518a.mxd s Lac m 523 llia d'Argent Eastman ui Q #substation 513 Austin, M 5 10 4 V 0 u , a Lac g e s Saint-Étienne- 112 o is Bolton-Ouest, M 6 Orford 3 g u 245 5 R de-Bolton, a BROME-MISSISQUOI M M (MRC) 72°25' 72°20' 72°15' Bolton-Est, M Document for information purposes only.
