The vote took place at a special meeting Tuesday. At a news conference later in the day, Gov. Ned Lamont and the principals involved in negotiating the public-private redevelopment said it sets up New London and the state of Connecticut as key players in the burgeoning offshore wind industry in the Northeast and would help the state achieve its renewable energy goals. The plan, which has been negotiated for 18 months by the port authority, port operator Gateway, offshore wind developers Ørsted and Eversource and more recently the state, involves redeveloping State Pier to handle heavy-lift cargo, including docking a large vessel, used to transport offshore wind components to the lease areas, on the eastern side of the pier. The plan also calls for filling in the area between the two existing piers to create additional storage space and will result in three berths.
