The United Illuminating Co. is preparing for a multi-year, $300 million transmission line upgrade along a 9.5-mile stretch of the railroad corridor between Milford and New Haven, officials with the Orange-based electric utility said. The project, which will begin in late 2023 and run until late 2028, will serve two purposes, company officials said in announcing the plan. Because UI’s transmission lines are part of a regional network and the work is being done to improve reliability of the delivery of electricity, the project will be funded by ISO-New England, the operator of the grid, company spokesman Gage Frank said. UI officials anticipate that the majority of construction will be scheduled for daytime hours. But in certain instances, nighttime work or around-the-clock construction may be necessary to accommodate the construction schedule and the needs of the railroad.
