Construction Finished On

$6B Transmission Project

NEW YORK—Last week, the Champlain Hudson Power Express marked the completion of its major transmission link connecting Québec’s hydropower system directly to New York City. The line is capable of delivering 1,250 MW to the city’s electrical grid, equivalent to 20% of New York City’s energy needs.

The completion of the $6 billion privately funded project is a historic milestone for New York State’s decarbonization goals and a blueprint for building large-scale clean energy infrastructure projects in the United States, New York State officials noted.

CHPE was created through a partnership between Transmission Developers, a Blackstone portfolio company, and Hydro-Québec, one of the largest hydropower producers in the world. The culmination of more than 15 years of planning and development, CHPE stretches 339 miles along the length of New York State, from the Canadian border to a converter station in Astoria, Queens, where the energy enters the New York City grid. Significant construction work was undertaken in the Hudson Valley by the region’s building trades.

The 339-mile Champlain Hudson Power Express is expected to deliver 10.4 terawatt-hours of clean energy per year to the New York Metro area – meeting up to 20% of the city’s needs—and reduce carbon emissions by 37 million metric tons through 2040.

The project will deliver power under a 25-year contract between Hydro-Québec and the New York State Energy Research and Development Authority (NYSERDA). Over the course of its three years of construction, CHPE was a major employment engine, creating 1,400 family-sustaining union jobs and generating more than 7.5 million work hours. The project will continue to deliver tangible financial and economic benefits to New York State ratepayers and communities along the project route.

TDI estimates that CHPE will save New York State ratepayers approximately $17.3 billion over the first 30 years of operation. The project will also provide an estimated $1.4 billion increase in tax revenue for local communities over the first 25 years of operation.

“The Champlain Hudson Power Express transmission line is one of the first projects I championed as Governor, and is a game changer when it comes to keeping the lights on, helping build a cleaner future and holding costs down,” New York Gov. Kathy Hochul said. “With its completion, we are powering 1 million New York City homes with needed clean energy that will serve communities for generations to come. This project is further proof that despite the unprecedented federal headwinds we are facing, New York will remain a national climate and clean energy leader into the future.”
