New York Governor Kathy Hochul announced the completion of the 1,250MW Champlain Hudson Power Express (CHPE) transmission line — a 339-mile high-voltage direct current (HVDC) link capable of delivering clean energy from Canada to New York City.
The line is expected to meet up to 20% of the city’s electricity needs, according to Utility Dive. It runs from Montreal to the Astoria Energy Complex in Queens, channeling hydropower into the densely populated metropolitan region.
This infrastructure project represents a major addition to the regional grid, reducing reliance on fossil-fuel-based generation. The route was buried underground and underwater, minimizing environmental disruption and avoiding overhead power lines through populated areas.
Geopolitically, the CHPE strengthens cross-border energy trade between the U.S. and Canada, leveraging Quebec’s abundant hydropower to serve New York’s climate goals of 70% renewable electricity by 2030.
However, critics note that long HVDC lines face cost overruns and permitting delays — the CHPE was originally proposed over a decade ago. Its actual impact depends on seasonal hydropower availability and transmission congestion pricing in New York’s wholesale market.
