The rebuild of the transmission line is now complete
Maintaining infrastructure is one of the many ways we support the safe and secure transmission of electricity throughout the region.
The 1191 Line was originally built in 1933. This project replaced all original wood structures (97 in total), three steel structures and one lattice tower with new weathering steel monopoles.
In addition, the project scope involved replacing the existing conductor (wire) due to age and condition.
The 115-kilovolt (kV) electric line spanned approximately 10 miles of Eversource right-of-way (transmission line corridor) between our Frost Bridge Substation in Watertown and Campville Substation in Harwinton.
It traversed Watertown, Thomaston, Litchfield and Harwinton.
