Québec–New Hampshire Interconnection

INFORMATION ON THE SOLUTION SELEC TED • Summer 2015

The goal of this Hydro-Québec TransÉnergie project is to increase the energy interchange capacity between Québec and New England by building an interconnection to link Québec’s power grid with New Hampshire’s. Commissioning is scheduled for 2019.

Connecting the gridsThe project involves the construction of a 320-kV direct-current transmission line, about 80 km long, in Québec. This line will be extended into the U.S.A. and will connect Des Cantons substation in Val-Joli to Franklin sub-station in southern New Hampshire. To supply the planned transmission line, equipment that converts alter-nating current to direct current will be added to Des Cantons substation. No expansion of the existing Des Cantons substation is required.

Environmental studies From the start of the draft-design study, Hydro-Québec delineated a vast study area to expand its knowledge of the territory. Hydro-Québec confirmed that the route with the least impact consists in running the new 320-kV line near the existing 450-kV line over the longest possible distance.

The study area (571 km2) covers parts of three regional county municipalities (MRCs): Val-Saint-François, Haut-Saint-François and Coaticook. Within these MRCs, it crosses through the following municipalities: Val-Joli, Stoke, Ascot Corner, Cookshire-Eaton, Saint-Isidore-de-Clifton, Martinville, Sainte-Edwidge- de-Clifton, Saint-Malo, Saint-Venant-de-Paquette, East Hereford and Saint-Herménégilde.

Work completed in recent monthsEnvironmental field surveys were carried out in spring and summer 2015.

Field crews recorded numerous com-ponents of the biophysical environment (rare plants, snakes, etc.) in the section of the new line route that runs parallel to the existing 450-kV line and along the path of the variants studied.

Each variant was evaluated based on its impacts on the region’s landscape, as well as on the human and natural environments (noise, archeology, etc.).

Key role of host community’s commentsIn recent months, Hydro-Québec has been working with local authorities to obtain information on the host community and gather their opinion on the route under study (i.e., the section that runs parallel to the 450-kV line and the four variants in the other section). In addition, last June, we held meetings with the host community to present the project and gather comments. The community’s input had a decisive influence on the solution selected.

Location criteria for the lineIn developing the line route, the following main criteria were taken into account: • Run the line along the existing 450-kV line wherever

possible.

• Avoid siting near homes as much as possible.

• As much as possible, avoid sensitive elements such as farmland, sugar bush operations, exceptional forest ecosystems, habitats of special-status plant and animal species, wetlands and recreational or tourist sites.

• Avoid the highlands of the Mont Hereford massif.

• Avoid open spaces and sites offering panoramic views.

• Optimize line design with a view to harmonious integration into the environment.

450-kV transmission line

Selected line routeBased on the results of its studies and the comments from community representatives and the public, Hydro-Québec has opted for the route described below.

For 80% of its length, from Des Cantons substation to the municipality of Saint-Malo, the planned line will run along the east side of the 450-kV line.

In the southern section, Hydro-Québec studied four variants that took into account technical and environmental criteria and the community’s suggestions and concerns. To reach the crossing point, the line will run west of the mountain, mainly because this side allows for a better integration into the landscape. By selecting this route, Hydro-Québec aims to bypass Mont Hereford and not interfere with outdoor activities, which are practiced more widely east of the mountain.

In addition, Hydro-Québec is currently working on optimizing the selected route by taking into account comments from residents and local authorities.

Tangible support for community developmentHydro-Québec sees its projects as an opportunity to participate in the development of host communities. With this in mind, it grants eligible organizations funding equivalent to 1% of the initially authorized value of the facilities covered by the Integrated Enhancement Program, to be used for local enhancement initiatives that improve the community.

Improved mitigation measuresStarting at the project design phase, Hydro-Québec implements a number of mitigation measures, including selecting the most suitable types of towers and careful tower siting. In this project, towers will be erected side by side when possible when the two lines are parallel, especially in open areas.

Tower types and right-of-wayThis will be the first 320-kV DC line built by Hydro-Québec, so a new type of steel tower will be used.

These towers will be similar to the ones for the existing 450-kV line, but will be smaller. They will be installed near existing towers wherever possible.
