Tecogen Inc. designs, manufactures, installs, and maintains high-efficiency, on-site energy systems. The company specializes in natural gas engine-driven Combined Heat and Power (CHP), or cogeneration, products. These systems generate electricity while simultaneously capturing waste heat from the engine to produce usable hot water, significantly increasing fuel efficiency. Tecogen's product portfolio also includes engine-driven chillers and air conditioning systems that provide cooling and hot water. The company's technologies are engineered for commercial and industrial facilities to reduce energy costs, lower greenhouse gas emissions, and provide reliable power during grid outages.
