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

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.
