Overview
The 17-mile long Spencer to Webster Transmission Project (T20 Line ACR project) involves the replacement of the existing 69 kilovolt (kV) transmission line through the municipalities of Spencer, Charlton, Dudley, and Webster. The project plans to replace all of the existing 69 kV wood-pole structures with steel structures between the Meadow Street Substation in Spencer and the East Webster Substation in Webster. The transmission infrastructure will be designed to 115 kV specifications but will operate at 69 kV until there is a need for additional capacity. We expect construction to begin early 2030 through early 2032 with final restoration efforts lasting through early Summer 2032. Public outreach in these communities has been ongoing. This project is currently in the planning phase and is awaiting permitting approvals.
