Why Are We Doing This Project?
Maintaining infrastructure is one of the many ways we support the safe and secure transmission of electricity throughout the region.
Portions of this power line corridor, which include the 1580, 1560 and 1808 lines, were originally built in the 1930s. Due to their age and condition, all existing lattice towers (117 in total) will be replaced with new steel monopoles.
In select areas, additional new monopole structures will be installed within the right-of-way to meet updated engineering and electric code standards.
The location and heights of the new structures will vary depending on topography, environmental resources and other factors.
This project also proposes to replace the conductor (energized wires) with new, upgraded wire of the same voltage, and the shield wire (top-most wire) with new Optical Ground Wire (OPGW). The OPGW is designed to improve electric reliability by enabling communications between substations.
Where Is This Work Being Done?
We're proposing to rebuild the 115-kilovolt (kV) electric transmission lines that span approximately 8 miles between our Stevenson Substation located at the Stevenson Dam in Monroe and the United Illuminating-owned Pootatuck Substation located at 14 Old Stratford Road in Shelton.
