Hertel–New York interconnection line
See the recently published Bureau des audiences publiques sur l’environnement (BAPE) report on the Hertel–New York interconnection line project.
Hydro-Québec welcomes the report, which states that the Commission of Inquiry is satisfied with the company’s explanations and commitments regarding specific issues related to agriculture.
The Hertel–New York interconnection line project aims to supply clean, renewable energy to New York City. In Québec, the project involves the construction of a line that will span 57.7 km (56.1 km underground and 1.6 km underwater). This 400-kV direct current line will connect Hertel substation in La Prairie to an interconnection point in the Rivière Richelieu at the Canada–United States border.
The project also includes installing a converter at Hertel substation. It will convert alternating current to direct current to supply the new interconnection.
The new line will connect to the line planned under the Champlain Hudson Power Express (CHPE) project, overseen by Transmission Developers Inc. (TDI) in the U.S. The CHPE project involves building an underground and underwater DC line between the Canada–U.S. border and New York City, a distance of roughly 545 km. In addition to receiving all required authorizations in the U.S., this project has been selected by the authorities of New York State to deliver hydropower to the heart of New York City.
