Market Dynamics

Drivers - Energy Efficiency Mandates and Carbon Emission Reduction Targets Across Industrial and Commercial Sectors

The U.S. government's commitment to achieving net-zero emissions by 2050 is driving unprecedented demand for CHP systems as businesses and institutions seek proven technologies to simultaneously reduce energy costs and environmental impact. According to the U.S. Department of Energy (DOE), there are 82.6 GW of CHP installed at nearly 4,400 sites around the country as of December 2016, with the number of CHP sites growing from 4,309 to 4,395 in 2016 alone. The EPA Combined Heat and Power Partnership established as a voluntary program has documented that CHP systems achieve total efficiencies (electrical and thermal) of up to 95% compared to conventional separate heat and power systems, with this improvement in efficiency translating to energy cost savings from reduced fuel use, reduced emissions of greenhouse gases and other regulated air pollutants, increased electricity-supply reliability and power quality, and reduced grid congestion and transmission and distribution losses.

The industrial sector, which represents 87% of existing CHP capacity, continues to expand installations in energy-intensive industries such as chemicals, paper, food processing, and pharmaceuticals, where significant thermal loads justify CHP deployment.
