Section 80 is referred to as a Pool Transmission Facility, which means it's a high-voltage transmission line that serves as a major component of the New England electric system. The section upgrade costs will be shared among New England customers, with more than 90 percent paid by other states.
In 2019, the Independent System Operator of New England (ISO-NE) identified this line as needing significant reliability improvements to mitigate capacity concerns, plus to meet current North America Electric Reliability Commission (NERC) standards. ISO-NE is responsible for regional transmission planning and ensuring that regional transmission systems can reliably deliver power to consumers under a wide range of system conditions.
