Division · Utility Infrastructure

Overhead. Underground.
Energized.
We work it all.

McDonough Electric has been building and maintaining New England's utility infrastructure since 1969. Overhead distribution, underground systems, medium-voltage construction, pole line rebuilds — this is the core of who we are.

The work that built this company.
Still the work we do best.

Utility infrastructure is not a service line for McDonough Electric — it is the foundation the company was built on in 1969. Five decades of overhead and underground distribution work across New England have given us relationships, credentials, and institutional knowledge that no newer contractor can replicate.

Our utility crews operate to the standards of the utilities we serve — union craft labor, proper clearances, documented safety practices, and a self-perform fleet that can handle everything from a single pole replacement to a multi-mile line rebuild.

Critical Capability

We work in
energized environments.
Safely. Every time.

McDonough Electric crews are trained and equipped for energized work — from distribution-voltage rubber glove operations to 345kV substation work under proper utility clearance and grounding. Every energized job follows strict minimum approach distance protocols and utility-approved work methods.

Rubber glove and hot-stick operations — distribution voltage

345kV substation work — under utility clearance and grounding

IBEW-trained craft labor — certified to utility standards

Utility operator coordination — every clearance documented
