Spencer to Webster Transmission
About the Project
The 17-mile-long Spencer to Webster Transmission Project, also known as the T20 Line Asset Condition Replacement Project, replaces the existing 69-kilovolt transmission line through the municipalities of Spencer, Charlton, Dudley, and Webster. The project plans to replace all existing 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 built to 115-kilovolt standards but will initially operate at 69 kilovolts until additional capacity is needed.
Construction is expected to take place from early 2030 to early 2032. Final restoration efforts are expected to continue into early Summer 2032. Public outreach in these communities has been ongoing. This project is currently in the planning phase and is awaiting permitting approvals.
Project Benefits
Modernizing the existing transmission lines by replacing all wood structures with steel structures mitigates future woodpecker activity.
The new line configuration will enhance system reliability by significantly reducing the likelihood of vegetation-related outages.
The project will provide additional transmission capacity and voltage support to meet increasing electricity demand by rebuilding the line to 115-kilovolt standards.
