NYC’s Big Clean Energy Plan Is Under Attack From One-Time Advocate

An ambitious project to deliver clean energy to New York City is facing sharp pushback from an environmental group that says the proposed transmission line will carry energy that’s not actually clean at all.

The $3 billion, Blackstone-backed Champlain Hudson Power Express project could begin construction as soon as mid-year after winning a state contract in November to provide Canadian hydropower to New York City—a key step in the city’s effort to wean itself from dirty fossil fuels. But local advocate Riverkeeper, a powerful environmental group that initially supported the plan, is now asking regulators to reject the deal, arguing that the hydro dams used to generate power are also significant sources of carbon emissions. The Sierra Club shares many of its concerns.
