Overview

Everhart & Hoover's substation experience ranges from design/build substations for commercial customers to ground-up projects for co-ops and large utilities.

Full design/build or construction from existing plans, our team handles site work, foundations, steel structures, buswork, equipment installation, and grounding systems. We coordinate with engineers and inspectors so every component meets code and performs for the long term.

Substation work requires precision, coordination, and strict safety. Planning and site prep come first, then phased construction, electrical integration, and testing. We deliver a fully functional system, ready for load.
