Our Legacy

Commonwealth was established in 1988, following the closing of another engineering firm’s Jackson, Michigan office. Our founders had worked closely together on domestic and foreign electric transmission and distribution projects for many years out of the Jackson office. Rather than leave Jackson, this team of individuals took action to incorporate under a name – Commonwealth Associates, Inc. (“Commonwealth”) – that was, and is, well known and respected in the electric power industry. The group devoted itself to structuring a new employee-owned company with the intent of upholding the previous Commonwealth Associates, Inc.’s reputation for providing high-quality engineering and consulting services.

Other talented individuals, many of whom had worked previously with the founders, were brought in to add their expertise. The new company flourished and in 1992, Commonwealth opened an office in the state of Washington to serve clients in the western United States. Another office was opened near Atlanta, Georgia in 2008, followed by a Columbus, Ohio, office opening in 2012. In 2013, Commonwealth expanded again – this time with an office in Spokane, Washington, to serve the Mountain West and Canada. In 2016, Commonwealth expanded East, establishing a Lancaster, Pennsylvania office.

Today, Commonwealth’s staff of approximately 280 professional and technical employees represents one of the most skilled, experienced technical resources available to analyze, plan, design, and construct electric power generation and delivery projects. In addition to licensed engineers and engineering specialists, we have experts in environmental sciences, permitting, Geographical Information Systems (GIS), surveying, right-of-way acquisition, and construction management, many with more than 20 years of experience in their field of expertise. Many of our professional engineers are active members of the Institute of Electrical and Electronics Engineers, American Society of Civil Engineers, Edison Electric Institute, and National Society of Professional Engineers, which allows for interaction and collaboration with our peers and access to influence the conversation in the power generation and T&D industries.

Commonwealth’s methods and tools have evolved over the years to incorporate emerging technologies and meet new challenges, and our commitment to engineering excellence and client satisfaction has never wavered.

We are committed, both as a firm, and as individuals to influencing and shaping the secure energy future.
