- The 339-mile CHPE transmission line goals to supply hydropower to 1,000,000 New York Metropolis houses.
- The underground transmission line will run via waterways, elevating some environmental considerations.
- This text is a part of “Remodeling Enterprise: Infrastructure,” a sequence exploring the developments reshaping US infrastructure.
Starting in 2026, 1,250 megawatts of electrical energy may velocity alongside 339 miles of underground cable to supply 1,000,000 New York Metropolis houses with hydropower generated in Canada.
The $6 billion Champlain Hudson Energy Categorical transmission line is beneath development to assist New York state meet its clean-energy targets.
It is also half of a bigger nationwide push to create extra transmission strains to deliver renewable vitality to the nation’s getting old electrical grid.
When CHPE (pronounced “chippy”) broke floor in 2022, it turned considered one of New York’s first Tier 4 initiatives, the state’s program geared toward sourcing 70 % of its electrical energy from renewable sources by 2030.
“We’re trying ahead to the day when we’re going to be turning on the change and bringing that clear vitality into New York Metropolis,” Donald Jessome, the founder and former CEO of Transmission Builders, the corporate behind CHPE, informed Enterprise Insider.
From nuclear to pure fuel to hydropower
The Indian Level nuclear plant as soon as supplied about 25% of New York Metropolis’s energy wants. New York shut it down in 2021 due to considerations about groundwater air pollution and the plant’s proximity to a metropolis of over 8 million folks.
The state has been making up for the loss with three natural-gas vegetation that got here on-line between 2018 and 2020. Based on EPA knowledge, carbon emissions within the New York Metropolis space rose by about 20% between 2019 and 2022.
These carbon-emitting vegetation are obligatory as a result of New York Metropolis is not well-connected to upstate’s plentiful renewable sources, like hydropower and wind. With so few transmission strains, about half of New York’s energy is generated by 24 fuel and fuel-oil vegetation inside the metropolis.

“Due to bottlenecks within the grid south of Albany, there is a restrict to the extent to which that era can be utilized to fulfill demand within the New York Metropolis space,” Ryan Calder, an assistant professor in environmental well being and coverage at Virginia Tech, informed Enterprise Insider.
CHPE will bypass Albany, Poughkeepsie, and different cities north of New York Metropolis. The transmission line will faucet into Hydro-Québec‘s current era and ship a fraction of it to New York, avoiding upstate bottlenecks that may tax the grid throughout peak-demand occasions.
Bringing renewable vitality to New York Metropolis
A lot of the US is struggling to attach renewable-energy initiatives to {the electrical} grid. About 930 gigawatts of photo voltaic, wind, nuclear, and different electrical energy sources are ready for grid entry, based on the Division of Vitality. That is greater than thrice as a lot wind and solar energy because the US generated in 2022 and sufficient to energy roughly 171 million houses.
Extra transmission infrastructure is essential to connecting new sources of carbon-free vitality.
CHPE
Transmission strains are like highways for electrons, Calder mentioned. They join sources of vitality era to areas of demand.
“Loads of renewable sources of electrical energy, wind, and hydroelectric energy in Canada are removed from densely populated city areas,” he mentioned.
As soon as CHPE is up and operating, it can cut back carbon emissions by 37 million metric tons, New York state officers mentioned in an announcement.
Although hydropower does emit greenhouse gases, a latest examine from Calder and his coauthors estimated the challenge will save a further $13.2 billion in social prices by 2050. That features doubtlessly stopping over 300 untimely deaths.
Fuel-fired energy vegetation contribute to poor air high quality, which might result in well being issues like bronchial asthma. The bronchial asthma charge for youngsters in New York Metropolis, particularly in poorer neighborhoods, is without doubt one of the highest within the nation. Switching to a cleaner vitality supply may enhance well being outcomes for youths and adults.
Buried cables from Canada to Queens
CHPE staff will bury the high-voltage direct present cables underground beneath Lake Champlain and the Hudson River, operating from the Canadian border and Queens, New York.
Environmental teams, together with the Sierra Membership and the Heart for Organic Variety, have objected to the challenge and the route. They’ve raised considerations over Atlantic sturgeon habitats and Hydro-Québec’s historical past with First Nation communities in Canada.
The corporate’s previous initiatives flooded Indigenous lands, a course of that created methylmercury, a neurotoxin, in waterways, Grist reported. Methylmercury accumulates in fish and may make its technique to people. Ingesting mercury can have severe well being results.
Others have expressed concern about CHPE’s monetary backing from the private-investment group Blackstone, which additionally invests in natural-gas pipelines.
Jessome mentioned TDI labored with native communities to handle their considerations about development.
CHPE
Because the CHPE development will not contain creating new dams, Calder mentioned he did not issue the influence of flooding into his examine. Different environmental considerations, resembling how the challenge may have an effect on fish habitats, had been exterior the scope of the examine.
New York has six years to attain its purpose of powering 70 % of its grid with renewable vitality. The state’s officers are banking CHPE offering a bit of that vitality.
“We’ll be in that group for the subsequent 60, 70, 80 years,” Jessome mentioned. “This challenge’s right here for the long run. It’ll have advantages properly into the longer term.”
April 30, 2024: This story was up to date to make clear that hydropower does emit greenhouse gases together with CO2, methane, and nitrous oxide.
