Reliability Upgrades

As part of our commitment to provide safe, reliable service to all of our customers, Central Maine Power (CMP) is updating our delivery system in your service area. While we are investing in upgrades to meet the community’s energy needs, we are working closely with our neighbors to ensure that all improvements are performed safely and with minimal disruption to your daily lives, the community, and the environment.

 

Currently CMP is planning upgrades in Somerville, Jefferson, Washington, and Windsor.

AVANGRID, the parent company of Central Maine Power, recently completed a survey of its transmission system to identify which sections were in need of attention to improve the reliability and safety of its electrical grid.

This project will completely rebuild a segment of the Section 49 transmission line that runs from Coopers Mills Substation in Windsor to Stickney’s Corner Substation along Route 220. This rebuild will upgrade nine miles of our 34.5kV transmission line to provide a strong source to areas served by the Coopers Mills Substation.

The original transmission line was built in the early 1900s, and was rebuilt in the mid-1920s.

The project includes replacing existing poles and cross arms with new wood poles and a new conductor.

Attempts are being made to convert pole rights to 100-foot wide easements.
