Tecogen Inc. TGEN

Company Overview

Tecogen Inc. is a U.S.-based clean energy company focused on the design, manufacture, installation, and maintenance of high-efficiency distributed energy systems. The company operates primarily in the energy technology and industrial equipment sectors, with a focus on combined heat and power (CHP), natural gas-powered cooling systems, heat pumps, and energy efficiency solutions. Tecogen’s products are designed to reduce energy costs and lower emissions for commercial, institutional, and industrial customers. Its core revenue drivers include equipment sales, long-term service contracts, installation services, and energy-related engineering solutions.

The company serves a range of end markets including healthcare facilities, multifamily residential buildings, hotels, educational institutions, data-oriented facilities, and industrial users. Tecogen has historically differentiated itself through proprietary engine control technologies and expertise in ultra-efficient natural gas engine systems that recover waste heat for productive use. The company traces its origins to technology developed at the Massachusetts Institute of Technology and was later commercialized through its predecessor entities before becoming publicly traded as Tecogen Inc. Over time, the company expanded from CHP systems into natural gas air conditioning, inverter-driven heat pump technologies, and emissions-control applications.
