Construction is underway at a Con Ed facility in Queens for a project called the Champlain Hudson Power Express, an underground transmission line that will bring hydroelectric power from Quebec, Canada to the city, cutting down on polluting emissions.

“People won’t even know it’s there. It will be able to take thousands of homes and power them with clean energy,” Gov. Kathy Hochul said.

It’ll deliver enough electricity to power to a million homes in the city, Hochul said.

Hochul joined officials for a ceremonial groundbreaking for the next part of the transmission project - a substation that will convert that hydroelectric power into something that will light and heat homes across the city.

She was joined by her counterpart in Canada, the premiere of Quebec, Francois Legault.

“I think Quebec can become the green battery of eastern North America, so we have to help our neighbors to do more,” he said.

Legault said it’s a win win deal to get energy from Hydro-Quebec, the public utility company in the province.

We get a fair price. New York gets a competitive price too," he said.

“The idea that you can bring hydroelectricity all the way from Quebec down to queens through a 339-mile transmission line is pretty remarkable,” said Justin Sauber, CEO of Transmission Developers, the company that conceived the project and is owned by the private equity firm Blackstone.

Sauber said the technology is there to build more of these projects, but there are limitations.

“Everyone needs power, but it’s expensive and transitioning off of cheaper fossil fuels - this, to me, is a great first step to see how it’s going to work and actually I think give us momentum to convince people that it’s the right thing to do in the long term,” Sauber said.

New York State has a goal of having 70% of its electricity produced by renewable energy by 2030.
