Pootatuck to West Devon Rebuild Project

Rebuilding existing 115 KV transmission lines between Pootatuck Substation in Shelton and West Devon Junction in Stratford.

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 includes the 1580, 1545, 1241, and 1483 lines, are deteriorating due to their age.

Originally built in the 1930s, 51 existing lattice structures will be replaced with 62 new weathering steel monopole structures for reliability purposes. 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 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 The Work Being Done?

We are rebuilding the 115-kilovolt (kV) transmission line infrastructure that span approximately 3.3 miles between the United Illuminating-owned Pootatuck Substation off Old Stratford Road in Shelton and an area near River Valley Road in Stratford called West Devon Junction.

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 are committed to updating neighbors, businesses, and all community members about project activities, especially during construction. Please remember 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.

Have Questions?

Keeping the lines of communication open is an important part of our work in your community.
