Stevenson to Pootatuck Rebuild Project

Rebuilding existing 115 kV transmission lines between Stevenson Substation in Monroe and Pootatuck Substation in Shelton.

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?

Construction Updates

We take every safety precaution while working in local communities, and all people working on the project carry identification. The project work will not interrupt electric service to homes or businesses.

We're committed to updating neighbors, businesses and all community members about project activities, especially during construction. Please keep in mind that the construction schedule may change due to weather or other unexpected circumstances.

Community Outreach

Beginning with municipal briefings and other community outreach efforts, we engage the community throughout the lifecycle of a project to provide information, answer questions and address concerns.

We're committed to updating neighbors, businesses and the community about construction activities in the project area
