New York Approves 90-Mile Transmission Line to Extend Quebec Hydropower Corridor
The project adds a fresh conduit for Canadian power into the U.S. Northeast, even as federal corridor policy retreats and D.C. Circuit litigation clouds the wider build-out.
New York regulators on Tuesday (2026-09-22) approved a 90-mile transmission line that would carry Canadian hydropower into New England, according to a filing, extending a cross-border build-out that has already reshaped power flows between Quebec and the U.S. Northeast.3
The approval adds another conduit linking Quebec's hydro surplus to a U.S. market importing at elevated levels. NYISO took in 52 GWh of electricity from Canada on July 3 (2026-07-03), the most traded between the two areas since January 2025, with some of that volume moving along the newly energised Champlain Hudson Power Express.6
The broader infrastructure push has produced measurable results. New York completed the 100-mile Smart Path Connect project, which is expected to deliver roughly $438m in annual benefits to households and businesses.5 The state also energised the 1.25GW CHPE line, a 339-mile high-voltage direct current link expected to deliver up to 10.4 TWh of clean electricity each year, enough to meet approximately 20% of New York City's energy needs.3
The CHPE contract for the New York State Energy Research and Development Authority to buy renewable energy credits from Hydro Quebec started on June 2 (2026-06-02), after the transmission line was completed.1 Harris estimated the line would cut carbon emissions by 3.7 million tons per year, the equivalent of removing 44% of vehicles from New York City's streets.1 The project is projected to generate more than $3.4bn in economic investment over its 25-year contract term and create more than 1,400 construction and operations jobs statewide.3
But the policy environment at the federal level has shifted against these projects. The Department of Energy announced on August 17 (2026-08-17) that it will not move forward with assigning National Interest Electric Transmission Corridor status to three routes selected by the previous administration — a setback for developers that had counted on that designation to streamline permitting.7
Texas shows how contested the build-out can become. The state's Public Utility Commission voted 5-0 on June 17 (2026-06-17) to temporarily halt the approval process for the first of five transmission lines, citing cost concerns. The broader Texas transmission programme could cost ratepayers at least $33bn and lead to more than 3,400 miles of extra-high-voltage power lines crossing the state.2
New England's own experiment is still being assessed. The New England Clean Energy Connect line started carrying electricity from Canada into Maine in January, and supporters hailed it as a milestone for renewable power. Whether it is paying off financially and operationally for ratepayers remains an open assessment.4
West Virginia regulators on September 4 (2026-09-04) denied requests by legal staff to delay evidentiary proceedings on NextEra's 107.5-mile MidAtlantic Resiliency Link transmission project, with hearings still scheduled for late October through early November.8 That decision keeps at least one mid-Atlantic corridor moving through regulatory review even as federal support contracts.
New York's ratepayers are the practical benchmark. The CHPE line's 25-year economics are projected to deliver over $3.4bn in total investment, and the Smart Path Connect project adds $438m in annual household and business benefits on top of that.3,5 Whether the next 90 miles can replicate those returns without National Interest Electric Transmission Corridor backing is a question developers and state regulators have not yet answered.
The next concrete signal is any further DOE or D.C. Circuit action on corridor designations that could affect the permitting timeline for projects already in the queue — or a Texas PUC decision on the remaining four transmission lines still awaiting review.7,2
