About H2DC

H2DC started in 2003 as a solution for companies that needed specialized services, but could not afford full-time professional engineering or project management staff. Since then, we’ve grown to provide contract electrical engineering services by the project or the specific work package, as well as project management, within the areas of renewable energy, electrical construction and RF compliance — for both tower or antenna work. Our goal is to provide the electrical engineering services necessary to get a project done on time and on budget.

In August 2026, H2DC became the New Hampshire Division of KMB Design Group, LLC.
