HVDC Transmission Project

Empire State Connector

The Empire State Connector will allow upstate generators to physically deliver their renewable, "zero emission" energy and capacity directly into New York City. The innovative route will use a submarine cable buried in the Erie Canal and Hudson River.

oneGRID is developing the Empire State Connector, a 1,000 megawatt High Voltage Direct Current (“HVDC”) electric transmission line connecting Upstate New York with New York City. Efficient and reliable Upstate New York energy will be collected at a converter station built near Utica. This energy is then converted from AC to DC and transmitted via two six-inch diameter non-fluidized solid-state cables over 260 miles directly into the heart of New York City, where the energy is then converted back to AC and injected into the grid.

The Project's cables will be routed primarily underwater in the Erie Canal and Hudson River and underground, where necessary, so that the project will have no visual impact. Once buried, the two, six-inch cables have low environmental impact.

Because of the precise controllability of HVDC technology, the energy physically delivered will qualify as “in-city” generation by the New York Independent System Operator, Inc. (“NYISO”). The injection of this zero emission power into New York will help improve air quality and reduce carbon emissions.

The Project is being built by union labor and it is anticipated it will create more than 500 construction jobs and 1,200 indirect jobs during the three-to-four-year construction period.

The target in-service date for the Project is 2021-2022.
