Monday marks the two-year anniversary of Eversourceâs decision to give up on its plan to construct a $1.6 billion, high voltage, 192-mile transmission line traversing New Hampshire from north to south. The Connecticut-based utility pulled the plug on the project, which would have been the stateâs largest construction project since the Seabrook nuclear power plant, after the state Supreme Court unanimously upheld the Site Evaluation Committeeâs 7-0 decision denying the companyâs application a week earlier. The court agreed with SEC the project would unduly impact the orderly development of the region, one of four criteria needed to approve a major utility project.
