A Full-Service Energy Solutions Provider  – An Ameresco Company

Plug Smart is a full-service, Ohio-based energy services division of Ameresco, Inc. with offices in Ohio, Michigan, Pennsylvania, Kentucky, Tennessee and Florida. Ameresco, Inc. (NYSE:AMRC) is a leading cleantech integrator and renewable energy asset developer, owner and operator with a business footprint across the United States, Canada, and United Kingdom.



Our History


In 1975, our company began by designing electrical engineering work under the name “Control Solutions” and grew quickly to a staff of over 500 with 17 offices nationwide. Due to the outstanding success, not long after its inception, the original company was sold to Schneider Electric.


After Control Solutions was sold, the core members of the previous team, alongside some fresh talent, developed a new perspective for delivering energy services projects to clients. Their mission was to approach complex facility improvement projects from the customers perspective with the key objectives of keeping pricing transparent and utilizing existing partnerships to deliver the best-value for their clients.


And from that, Plug Smart was formed in 2008.


Shortly after, the customer-focused approach began to take hold of the market. Our team quickly saw that there was a need in the industry for a financially straightforward company. We are adept at creating self-funding opportunities for our clients and providing them with unparalleled insights into pricing and ROI before, during and after project implementation. Our business model has become a much-appreciated hallmark of our client relationships.

Plug Smart has become one of the industry’s greatest success stories. We have the unique distinction of being selected as one of Inc. Magazine’s “500 Fastest” growing privately owned companies for 3 years in a row and were ranked #3 in Columbus Business First’s “Fast 50” for being one of the fastest growing companies in the region. Our organic growth is from working with clients in a variety of industries that have affirmed our customer-centered approach by establishing ongoing relationships.

Plug Smart was acquired by Ameresco, Inc. in 2021. 

Ameresco acquired Plug Smart in 2021, expanding its existing pipeline and solution offerings in the smart buildings sector. Plug Smart’s proven experience in building controls and smart building solutions compliments Ameresco’s approach to customizing energy solutions to best-fit our customer’s needs.

The Plug Smart team joined Ameresco’s team of 1,000+ employees and benefits from the ability to conduct projects across a broad solution portfolio, leveraging Ameresco’s capabilities in street lighting, solar PV arrays, battery energy storage systems, microgrids and more. The integration of smart building solution expertise directly serves Ameresco’s vision of offering tailored and innovative energy solutions to customers while growing expertise through expanding their teams of deep technical specialists.




"When we began designing our “white room,” we knew we needed an HVAC system that could keep the area clean and deliver precise conditions efficiently. Even though we were on a tight schedule, Plug Smart understood our requirements and designed just the right system, producing drawings in record time. They saw the construction through to the end and everything turned out superb!”
