McDonough Electric critical infrastructure work
Division · Critical Infrastructure

Complex sites.
Constrained environments.
Delivered.

Some of the most demanding infrastructure work happens in places that do not look like a typical job site — active industrial facilities, historic mill redevelopments, power generation plants, and confined urban environments where precision matters as much as technical capability.

The jobs that need the right contractor
the first time.

Critical infrastructure work does not allow for learning curves. When a power generation facility needs utility work inside an active substation, when a major urban redevelopment needs infrastructure relocated in a confined site, when an industrial facility needs multi-unit coordination with no room for error — the contractor has to already know what they are doing.

McDonough Electric has built its critical infrastructure capability over 55 years of operating in exactly these environments. Our crews have worked inside 345kV generating station substations, executed multi-unit pole work in active industrial facilities, and delivered utility infrastructure on complex urban redevelopment sites.

Strategic Direction
Where critical infrastructure is heading.
Active Target
Data Center Infrastructure
The AI infrastructure buildout is driving massive data center construction across New England. These facilities need utility-grade MV service, substation work, fiber backbone, and on-site generation.
Active Target
Government and Defense Facilities
Military installations, ports, and government campuses require credentialed contractors with IBEW union workforces. McDonough is positioned directly for this market.
Active Target
Industrial Energy Modernization
Large industrial facilities are investing in on-site generation, BESS, and grid modernization. McDonough can handle both the utility interconnect and the site electrical infrastructure.
Complex site. High stakes.
Right contractor.
55 years of operating in environments that demand it.
