Thanks to a well-trained, highly skilled workforce T.C. Holzen, Inc. has become a leader in both Substation Construction and Electrical Infrastructure installation in Southwest Ohio over the past decade. T.C. Holzen provides both civil and physical services in the electrical industry. The company’s site development capabilities enable us to be one of the fastest companies in the region to take a new site and develop it, complete with foundations, conduit, grounding grid, oil containment, and fencing. On top of that, our well-rounded work force, which possesses an extremely diverse skill set, allow us to take that developed site and set out our own columns, erect our own steel, complete our own bus work, and set most electrical equipment all in-house.
