The SOO Green HVDC Link is a first-of-its-kind electricity transmission project that will install state-of-the-art high-voltage direct current (HVDC) transmission cable underground along existing railroad corridors. SOO Green is pioneering an innovative model for developing transmission infrastructure to deliver renewable energy long distances to customers across the Eastern U.S. that virtually eliminates the visual, land and environmental impact of above-ground transmission lines. SOO Green will enable the development of new, low-cost renewable energy resources while enhancing the power grid’s reliability and resilience.

The monumental Soo Green HVDC transmission project, finally gained IUB approval in the fall of 2023. It’s truly an innovative, capital-intensive project that’s important in the big picture of the clean energy transition.

Background on the project and an outline of benefits appear on the Soo Green site, soogreen.com.
