120-kV Langlois–Vaudreuil-Soulanges Line and Supply for Ericsson

INFORMATION ON SOLUTION SELECTED • Spring 2016

The population of the regional county municipality (MRC) of Vaudreuil-Soulanges has grown significantly in the last decade. Between 2001 and 2014, the number of residents in the MRC increased by 43%.

Combined with industrial and commercial development, this population growth has led to a significant increase in the region’s electricity consumption and has overloaded the power system.

Hydro-Québec TransÉnergie needs to build a new 120-kilovolt (kV) transmission line on the territory of the Vaudreuil-Soulanges MRC.

From this new line, Hydro-Québec TransÉnergie will also build a line segment to supply Ericsson, which recently moved into Vaudreuil- Dorion’s industrial area.

Commissioning of the planned equipment is scheduled for 2017.

RESULTS OF THE PUBLIC PARTICIPATION PROCESSIn 2015, Hydro-Québec presented the line routes and consulted community representatives, affected landowners and the general population. This consultation allowed Hydro-Québec to learn their various concerns and gather their comments.

Hydro-Québec was able to improve its project and now proposes a slightly modified route that better meets community expectations.

SELECTED LINE ROUTEThe 120-kV double-circuit transmission line will consist of six conductors and be supported by steel towers. The line will be approximately 20 km long and will connect Langlois and Vaudreuil-Soulanges substations. Work is also planned inside Dorion, Langlois, Vaudreuil-Soulanges and Rigaud substations to integrate the new line to the power system.

No work is required from Langlois substation to Les Cèdres substation.

The new line will be divided into two segments.

From Les Cèdres substation to Dorion substation (segment 1)

This new 7-km-long segment will run along the existing line between Les Cèdres and Dorion substations. This route has the advantage of grouping together Hydro-Québec’s lines in a single corridor.

From Dorion substation to Vaudreuil-Soulanges substation (segment 2)

Hydro-Québec favored using existing rights-of-way to avoid the impacts associated with opening a new line corridor. For this segment, to be about 8.5 km long, the selected solution is to dismantle the existing line supported by wooden H-frames, and rebuild it on double-circuit steel towers in the same 30 m right-of-way. This option allows Hydro-Québec to use existing servitude rights.

ERICSSON SUPPLYHydro-Québec will also build a 3.5-km-long line segment to the Ericsson site at 3500A, Rue F.-X.-Tessier in Vaudreuil-Dorion, from the new Langlois–Vaudreuil-Soulanges line.

This segment will begin near Montée Labossière and will be composed of a 3-km-long overhead line. It will cross Highway 40 before reaching an overhead- underground junction substation located near the Joseph-Carrier industrial park, just east of Montée Cadieux. From this point, it will run underground to the Ericsson connection point since there isn’t enough room in the industrial park for an overhead line.

STAGES UNDERWAY AND TO COMESince December 2015, Hydro-Québec has held meetings with affected landowners and is carrying out field studies to determine the best location for each tower.

During 2016, Hydro-Québec will complete engineering work and will obtain the necessary government approvals to carry out the project.

Commissioning of the new line is planned for 2017.
