The 545-kilometer underground power line, most of which will run under water, is considered a major project for Hydro-Québec and will deliver 10.4 terawatt hours of electricity per year from New York to the city.

Under the service agreement announced Thursday, SNC-Lavalin will provide engineering supervision and design coordination for the cables and converter station in the United States, the Montreal-based company said.

The transmission line will depart from Hydro-Québec’s Hertel substation in La Prairie and cross the US border under Lake Champlain. It will then head south to connect to a converter station in Astoria, Queens, New York.

According to Ian Edwards, President and CEO of SNC-Lavalin, this mandate allows the engineering firm to increase its presence in the United States, one of its key markets, and demonstrates its commitment and ability to “offer solutions to bring carbon neutrality to the market to achieve” and to its customers.

Construction in the United States is expected to begin this summer, with commissioning scheduled for 2025. In Quebec, construction of the line could begin in spring 2023, Hydro-Quebec said earlier this month, but has yet to be verified by the Bureau d’audiences publiques sur l’environnement and Canada’s energy regulator.

Dale Clarke, SNC-Lavalin’s Chief Engineering Services Officer in Canada, said the contract “strengthens SNC-Lavalin’s position as a global leader in power grids, particularly in high-voltage direct current (HVDC) technology used in submarine and marine applications underground cable is used”.

The Champlain Hudson Power Express project will be executed directly from SNC-Lavalin’s HVDC Competence Center in Montreal. It has been in business for about 50 years and has completed several projects including the Western Alberta Power Line Project and the Lower Churchill Project.
