NKT announced the commercial launch of the Champlain Hudson Power Express HVDC transmission line. This critical infrastructure system connects the province of Quebec with the New York City metropolitan area through a deployment that was completed ahead of the developers’ original schedule.
The project required the design and manufacture of a 400-kV power cable system adapted to complex conditions. The installation spanned challenging aquatic and terrestrial environments, including Lake Champlain, the Hudson River, and the Harlem River.
In addition, the total length of the power lines exceeds 600 kilometers to ensure the large-scale transmission of electricity. NKT undertook the project on a turnkey basis, handling the engineering, supply, and underwater and onshore installation of the electrical infrastructure.
Key partnerships for the energy transition in New York
Meanwhile, the completion of the operational work was officially celebrated on June 16, 2026, in New York. The ceremony was attended by executives from the technology firm, representatives from Transmission Developers, and members of Hydro-Québec.
In addition, NKT President and CEO Claes Westerlind highlighted the value of long-term strategic cooperation in strengthening the supply of clean energy in North America. He noted what a privilege it was to work hand in hand with partner companies to bring this mega infrastructure project to fruition.
Capacity of the new 400-kV power line from Champlain Hudson Power Express
In terms of operational benefits, the infrastructure has an installed capacity to transmit up to 1,250 megawatts of renewable hydroelectric power. This influx of power will reduce the metropolis’s reliance on fossil fuels, stabilize the local grid’s supply, and reduce polluting emissions in the region.
