Empire State Connector

oneGRID is developing the Empire State Connector, a 265 mile long, 1,000 megawatt HVDC electric transmission line connecting Upstate New York to New York City. Efficient and reliable upstate New York energy will be collected at a converter station built near Utica. The project will provide an opportunity for the NYISO to provide new sources of energy, including from renewable sources, to power the largest city in the United States, while spurring economic development and jobs in upstate and all along the line. The majority of the 320-kV HVDC line will be laid in an underwater trench below the Erie Canal and Hudson River, although some sections will be buried. This project is expected to be completed between 2021 and 2022. According to THUB calculations, the project has an estimated cost of $1,000m.
