Brighton Electric Avenue Substation Reliability Project
With the demand for electricity continuing to grow in the Allston-Brighton area, Eversource built a new substation on Electric Avenue in Brighton to help reliably deliver electricity and increase capacity to our customers.
At Eversource, we're always working to serve you better. To address reliability and capacity issues throughout the Allston, Brighton, and Watertown areas, Eversource installed two new 115-kilovolt (kV) transmission line segments. Eversource also constructed a new substation on Electric Avenue in Brighton; the new substation will connect to four existing substations around the region. Currently, we are installing 13.8-kV distribution lines along neighboring streets in the area.
At the substation site, new switchgear, transformers, associated metering, protective relaying, control wiring and a security fence have been installed to connect the area's 115-kV transmission line to the local 13.8-kV distribution system.
Department of Public Utilities
To construct and operate a new 115/14-kV substation, two new 115-kV underground transmission cables and an underground distribution conduit, Eversource filed a petition with the Massachusetts Department of Public Utilities (DPU); the petition filing is part of the regulatory review process, as defined by Massachusetts state statutes.

Eversource is committed to updating neighbors, business and community members about project activities during construction. Construction will not interrupt electric service to homes or businesses. Also, please keep in mind the constructions schedule might be impacted by weather or unexpected circumstances.
All employees working on the project carry proper identification, and Eversource always makes safety a priority in all the work we do.
Beginning the week of April 22, 2019: Eversource will complete roadway restoration for the Brighton Electric Avenue Substation Reliability Project. Restoration will begin on Electric Avenue between Parsons Street and Goodenough Street. We will be excavating, grading, and paving the roadways as well as reconstructing the sidewalks along Electric Avenue.
Arsenal Street - Construction is complete. Final restoration will take place in third quarter 2019.
Traffic Management Plans
Working in consultation with town and state officials, including the Mass. Department of Transportation, Eversource has developed a set of Traffic Management Plans (TMPs) for each section of the Electric Avenue Substation Reliability Project.
The TMPs include conditions specific to routing as made by the DPU in its final decision. The TMPs illustrate detailed site plans, showing underground line locations, hours of construction, area-specific traffic controls, and more. Please note, TMPs are subject to change and may be updated.
