Forest Avenue Substation

Reliability Upgrades

Forest Avenue Substation, Portland

 

Project Overview

Central Maine Power Company (CMP), in conjunction with its parent company AVANGRID, is undertaking a multi-year effort to upgrade or replace 10 distribution substations throughout its service territory, including one in Portland, that have aged and/or have condition or capacity issues in need of attention.

 

As part of CMP’s Substation Modernization  Plan, the Forest Avenue Substation, located at 14 Marginal Way, needs improvement so we  can continue to provide safe, reliable and  stable service to meet our customers’  energy needs.

CMP is working with communities and  reaching out to neighbors to ensure that all improvements are performed safely and with minimal disruptions to their daily lives, the  community, and the environment.

 

Project Purpose and Need 

Forest Avenue Substation has aged, and  the addition of new components along with  the replacement of older ones will enhance  functionality plus meet updated AVANGRID  and National Electrical Safety Code (NESC)  standards.

 

CMP plans to expand the existing yard by  approximately 10,000 square feet, more than double its current footprint of approximately 9,000 square feet, to accommodate the  improvements. We’ll access the property from our existing driveway on Marginal Way.
