The 735-kV lines in Hydro-Québec’s
transmission system have been
commissioned gradually since
the mid-1960s. These lines carry
the electric power produced by
generating facilities located primarily
in the Baie-James and Côte-Nord
regions to major load centres in
southern Québec.

Since 2011, the power transmission system has undergone significant changes:
• Reduced consumption in the Côte-Nord area
• Decommissioning of the Tracy and La Citière thermal and Gentilly-2 nuclear generating stations
These changes have brought about an increase to the power flow on the lines of the Manic-Québec
corridor toward the major load centres and decreased the reliability of the transmission system.
Hydro-Québec is thus required to take steps in order to restore adequate transmission capacity
to the corridor and maintain system reliability.

PROPOSED SOLUTION
After considering a number of scenarios,
Hydro-Québec believes that the best solution
is to build a new 735-kV line extending some
250 km between Micoua substation in the
Côte-Nord region and Saguenay substation
in Saguenay–Lac-Saint-Jean. The project also
includes adding equipment to both substations
and expanding Saguenay substation.
In addition to maintaining system reliability,
the project will reinforce the Manic-Québec
corridor, which is located in areas with a high
risk of icing, by adding a more robust link.
The new line will meet technical criteria
allowing it to better withstand weather
events like wind, rime and freezing rain.
As an added benefit, the project will also
reduce energy losses while improving
system operating flexibility.
MICOUA SUBSTATION
In short, the construction of a new
735-kV line between Micoua and
Saguenay substations will:
• Maintain transmission system reliability
• Reinforce the Manic-Québec corridor
• Reduce energy losses
• Increase the system’s operating flexibility

STUDY AREA
Measuring 255 km in length and 15 to 20 km in width, the study area is bounded
to the east by Micoua substation, located near the Manic-3 generating station;
to the west by Saguenay substation, located in the city of Saguenay; and to
the south by the existing Micoua-Saguenay 735-kV line. Its northern boundary
skirts such major water bodies as Lac La Mothe and the Outardes 4 and
Pipmuacan reservoirs.
The study area bypasses the two proposed biodiversity reserves of Brûlis-dulac-Frégate and Plateau-du-Lac-des-Huit-Chutes as well as the Parc national
des Monts-Valin.
THE NORTHERN PART of the study area, located in the Laurentian Plateau
highlands, is characterized by rugged terrain and includes areas at high risk
of icing, with numerous lakes and rivers and scattered peat bogs. The area
is noted for its vacation areas, hunting and fishing as well as natural resource
extraction, including forestry.
THE SOUTHERN PART, located in the Saguenay–Lac-Saint-Jean lowlands, is a
plain bisected by the Rivière Saguenay with a number of large, deep peat bogs.
Largely given over to agriculture and agroforestry, it features a few urban and
industrial areas.
The study area will enable Hydro-Québec to determine line routes that meet
the criteria of system security and reliability.

HOST ENVIRONMENT
The study area crosses two administrative regions: Côte-Nord and Saguenay–LacSaint-Jean. It includes three regional county municipalities (MRCs), one city/MRC,
six municipalities and four unorganized territories.
Most of the study area is public land. However, the southern part consists almost
entirely of private land.

FUTURE STUDIES
In the coming months, Hydro-Québec will conduct environ­
mental and technical studies in the study area to gain a better
understanding of the host environment.
The environmental studies will examine such matters as fauna
and flora, land use, landscape and archaeology. The technical
studies will cover areas subject to frost, freezing rain and
erosion as well as surface materials.
LINE ROUTE DEVELOPMENT
To develop the line routes, Hydro-Québec will consider
sensitive environmental features such as the built environment,
landscape, heritage sites, resort areas, biological refuges,
wetlands and the habitats of special-status wildlife species.
It will also take into account technical constraints and
community concerns. This will be followed by a comparative
analysis of potential line routes to identify the solution with
the least impact.
PUBLIC PARTICIPATION
Favorable reception from local communities is an essential
condition for Hydro-Québec projects. The company develops
each new project with a view to striking a balance between
the three pillars of sustainable development: environmental,
social and economic aspects.
As a result, Hydro-Québec has implemented a public
participation and consultation process. This measure allows
the company to take into account the concerns of the
community and its leaders so as to best adapt the project
to local realities.
In the coming weeks, Hydro-Québec will meet with
community groups and organizations to share information
on the project and gather residents’ concerns.
