As of April 13, 2026, the Federal Energy Regulatory Commission (FERC) approved the market rules for the Champlain Hudson Power Express project. [1] The project is a $6-billion, 1,250 MW merchant transmission line that will start delivering hydropower from Canada to New York City in May 2026. [2] The line spans over 300 miles and is slated to deliver 10.4 TWh a year from Hydro-Québec under a 25-year contract with the New York State Energy Research and Development Authority. [3] The market rules that were approved include revisions to New York ISO’s (NYISO) Open Access Transmission Tariff and its Market Administration and Control Area Services Tariff. The revisions will allow NYISO to integrate the project’s physical reservation model with the ISO’s financial reservation system. The project will be NYISO’s first transmission facility that employs physical reservations to allocate transmission rights.
