Company Overview

Tecogen Inc. designs, manufactures and sells on‐site power generation and combined heat and power (CHP) systems for commercial, industrial and institutional markets. The company’s natural gas–fueled cogeneration units produce electricity while capturing and reusing waste heat for space and water heating, providing enhanced energy efficiency over traditional utility‐supplied electrical systems. Tecogen’s portfolio also includes ultra‐low NOx emission technologies, absorption chillers and ancillary equipment tailored to meet the specific demands of manufacturing facilities, hospitals, universities and other energy‐intensive customers.

Central to Tecogen’s product lineup is its InVerde e+ series of cogeneration modules, which integrate internally developed low‐emission combustion systems with advanced controls to optimize performance and reliability. The company pairs these units with its Tecochill absorption chillers to deliver combined cooling, heating and power (CCHP) solutions capable of simultaneously meeting space cooling, heating and electrical load requirements. Tecogen also offers turnkey installation, remote performance monitoring and preventative maintenance services to support customer operations over the lifecycle of each system.

Headquartered in Waltham, Massachusetts, Tecogen serves markets across the United States and has expanded its reach through strategic distribution partnerships. The company caters to a broad spectrum of end users—ranging from food and beverage processors to recreational facilities—and collaborates with engineering firms, energy service companies and municipal authorities to integrate CHP and CCHP into larger energy management projects.

Founded in 2006, Tecogen is led by President and Chief Executive Officer Benjamin D. Locke, who has guided the company’s growth in product innovation and aftermarket support. With a focus on reducing greenhouse gas emissions and lowering operational costs for customers, Tecogen continues to refine its technology suite and pursue new markets for high‐efficiency, on‐site energy solutions.
