TL;DR
A new HVDC transmission line from Quebec to New York City is now operational, supplying 20% of NYC’s electricity with clean hydropower. This development counters Trump-era policies favoring fossil fuels and marks a significant step in NYC’s clean energy transition.
On June 16, 2023, New York Governor Kathy Hochul announced that the Champlain Hudson Power Express, a 1.25 gigawatt hydropower transmission line from Quebec, is now fully operational, delivering clean energy to New York City and reducing local carbon emissions.
The new HVDC line, supported by Hitachi Energy’s technology, supplies up to 20% of NYC’s electricity needs by connecting hydropower resources in Quebec to the Astoria Energy Complex in Queens. The project, developed by Transmission Developers, Inc. in partnership with Hydro-Québec, aims to cut carbon emissions by approximately 3.9 million metric tons annually, equivalent to nearly half of NYC’s car fleet emissions.
Construction began in 2022 after years of planning, with the project initially conceived around 2011. It became a focal point in the city’s efforts to transition away from fossil fuels, especially as New York’s natural gas plants face increasing pressure to retire. The line’s activation is seen as a major milestone in the city’s climate strategy, supporting the state’s push for a cleaner, more resilient energy grid.
Impact of Hydropower on NYC’s Climate Goals
The operation of the Champlain Hudson Power Express represents a significant step toward New York’s goal of reducing greenhouse gas emissions and transitioning to renewable energy sources. It demonstrates the feasibility and economic benefits of large-scale hydropower imports, challenging the narrative that fossil fuels are necessary for reliable power. The project also highlights the role of advanced HVDC technology in urban energy infrastructure, offering a more resilient and less disruptive method of transmission.
Moreover, this development signals a political and economic shift, as it counters efforts by the Trump administration to hinder clean energy projects. The project’s completion is viewed as a victory for climate advocates and a setback for fossil fuel interests aligned with Trump’s policies, which have sought to limit renewable energy expansion and favor coal and natural gas.

Background of NYC’s Hydropower and Energy Transition
The Champlain Hudson Power Express project has been in development since around 2011, amid broader efforts to diversify New York’s energy sources and meet aggressive climate targets. The line connects hydropower facilities in Quebec, which have a long history of providing renewable energy, to New York City’s grid. Its construction faced delays and political opposition, notably from the Trump administration, which attempted to block or undermine various clean energy initiatives, including offshore wind projects and cross-border transmission lines.
In recent years, New York has accelerated its clean energy policies, phasing out coal and reducing reliance on natural gas plants. The project’s activation aligns with the state’s Climate Leadership and Community Protection Act, aiming for 70% renewable energy by 2030 and a fully carbon-neutral grid by 2040. The line’s completion also reuses a former fossil fuel site in Astoria, transforming it into a hub for clean energy infrastructure.
“With its completion, we are powering 1 million New York City homes with needed clean energy that will serve communities for generations to come.”
— Governor Kathy Hochul

Unresolved Questions About Project Impact and Future Developments
While the line is now operational, it remains unclear how quickly it will displace natural gas and other fossil fuel sources in practice, or how it will influence broader regional energy markets. The long-term economic and environmental impacts depend on future policy decisions, market dynamics, and potential technological upgrades. Additionally, the extent to which this project will inspire similar infrastructure in other regions is still uncertain.
