Note: kV is the abbreviation for kilovolt, which is equal to 1,000 volts. 120/25-kV Gracefield Substation and 120-kV Lines INFORMATION ON THE SOLUTION SELECTED • November 2015 To meet growing demand for electricity, Hydro-Québec conducted draft-design studies in winter 2013-2014 to build a 120/25-kV* transformer substation in Gracefield and rebuild the 120-kV transmission line between Paugan substation, in Low, and Maniwaki substation, in Egan-Sud. The 65-km line will be rebuilt in the middle of the corridor occupied by the current line. Since the plan calls for adding a circuit, a new 5-km line must be built that follows the existing line from Déléage to the entry to Maniwaki substation. In addition, a 120-kV line about 5.3 km long must be built to supply the new Gracefield substation. This bulletin describes the lowest-impact solution selected by Hydro-Québec. 76°0' Egan-Sud, M Aumond, CT ! 107 PROJECT TO DATE Maniwaki, V Maniwaki ComposantesProject components du projet #substation In the previous steps of this project, TracéSelected retenu route pour for l’alimentation Gracefield Hydro-Québec carried out an inventory dusubstation poste de supply Gracefield line !

The current line on wooden H-frames will be dismantled before construction begins. The line will be supported by guyed steel lattice towers in forested areas and reduced-footprint towers in farmland. To accommodate an additional circuit, the right-of-way must be widened by 4.3 m on either side of the line, for a total width of 39 m.

For the entry to Maniwaki substation, Hydro-Québec has selected Variant A, which routes the new line south of the current line, passing between existing buildings. The company optimized this variant based on concerns expressed by local representatives and affected landowners. The line segment will be supported by four-legged lattice towers as well as reduced-footprint lattice towers.

This site is close to the load centre Gracefield substation and 25-kV distribution system and uses the existing access road and ditches. It minimizes environmental and social impacts by limiting modifications to the landscape. The fenced area of the planned substation will be about 100 m by 75 m, not including drainage ditches on its periphery. While the planned substation will be built primarily on a lot belonging to Hydro-Québec, the company must acquire part of the adjacent property to accommodate all equipment. The substation will be supplied by two 120-kV circuits from the main line. A prefabricated 105 building will house the control, protection and telecommunications equipment. 0 50 100 m Related work will be required at Paugan and UTM, zone 18, NAD83 Maniwaki substations to add or modify 120-kV 7339_bu_tet_045_poste_151015.mxd outgoing line structures. This work will take place entirely on Hydro-Québec property. Gracefield substation supply line Based on the draft-design studies and the public consultation process, Hydro-Québec selected Route A. This 5.3-km route runs along property boundaries for about 1.8 km, then crosses Chemin Henri and 800 m further turns to follow the relief for better landscape integration and reduced visibility from Route 105. This route also limits the impact on farmland and some wetlands. The substation supply line will be supported by guyed steel lattice towers in forested areas and reduced-footprint towers in farmland. The planned right-of-way is 39 m wide. 6 GRACEFIELD SUBSTATION SUPPLY LINE Chemin 15 15A Lac 76°2' 15 76°0' Paquin 15 220 C C h h e 160 e 40 39 38 37 36 35 34 33 32 31 m 30A 29 28 27 26 26 m i n i n 16 230 200 200 H d u 220 210 e n 46°7'30" r D 46°7'30" i o m a i 17 n e 105 150 210 18 200 19 200 route Ch em 30B in 180 220 La ch ap el 20 le 25 Selected 200 190 21 200 200 46°6'45" 190 46°6'45" 190 180 35 44A 43A 42 41 190 33A 33B 34 170 h ep os Project components 160 -J 170 nt ai 170 S Planned Gracefield substation 180 e Rivière-Gatineau u 180 R la Selected route Gatineau 200 de Transmission line to be rebuilt Planned Gracefield substation 30 32 33 34 35 32A31 32B 200 160 d Current Gracefield substation an Chemin 200 # rtr # Existing 69-kV substation and Be hemin transmission line 210 C Rivière031 330 660 m 180 30 The property boundaries shown on this map are MTM, zone 9, NAD83 76°2' 7339_bu_tet_020_derivation_151015.mxd approximate76°0' and provided for reference only. 6°6' 46°6' 4 150 230 Planned 120-kV Maniwaki # double-circuit line substation Mont-Laurier tap 105 Messines # substation Right-of-way boundary Right-of-way boundary Gracefield # substation (to be rebuilt) 22 to 38 m # Kazabazua 301 substation 5.0 m 19.5 m 19.5 m 5.0 m Paugan # substation Clearing easement 39.0 m Clearing easement 105 7339_buf2_tet_017_ligneDeri_150505.fh9 # 7339_bu_tet_042_pyloneGrace_151015.mxd 366 7 Tangible support for About the construction work community development Hydro-Québec has planned two phases of construction work.
