Combined Heat and Power Partnership
EPA's CHP Partnership
What is EPA's CHP Partnership?
The CHP Partnership seeks to reduce the environmental impacts of electric power generation by promoting the use of CHP. The Partnership works closely with energy users; the CHP industry; state, local, and tribal governments; clean air officials; and other clean energy stakeholders to facilitate the development of new projects.
The Partnership offers:
- Basic information about CHP and its benefits
- Technical tools and resources such as the Catalog of CHP Technologies and the CHP Emissions Calculator
- Information about state and federal CHP policies and incentives
- Guidance on CHP project development
- ENERGY STAR® CHP Awards
- CHP news and webinars
Visit "About Us" for more information.

What is CHP?
Combined heat and power (CHP), also known as cogeneration, is the simultaneous production of electricity and heat from a single fuel source, such as natural gas, biomass, biogas, coal, waste heat, or oil. CHP is not a single technology, but an integrated energy system that can be modified depending upon the needs of the energy end user. By installing a CHP system designed to meet the thermal and electrical base loads of a facility, CHP can greatly increase the facility's operational efficiency and decrease energy costs. More information can be found on the Basic Information page.
How does CHP work, and what are the key technologies?
CHP systems consist of a number of individual components configured into an integrated whole. These components include the prime mover (i.e., heat engine), generator, heat recovery, and electrical interconnection. The type of equipment that drives the overall system (i.e., the prime mover) typically identifies the CHP system. Prime movers for CHP systems include reciprocating engines, combustion or gas turbines, steam turbines, microturbines, and fuel cells. Detailed information about how CHP technologies work along with cost and performance information can be found in the Catalog of CHP Technologies.
What fuels can be used in CHP systems?
CHP systems are "fuel-neutral," which means that they can run on a variety of fuel types, such as natural gas, biomass, biogas, coal, waste heat, or oil. The type of fuel used depends on availability and the type of prime mover employed. More information about the fuels available for different prime movers can be found in the Catalog of CHP Technologies. In addition, information specific to biomass-fueled CHP can be found on the Biomass CHP page and in the Biomass CHP Catalog of Technologies.
What are the benefits of CHP?
CHP plays an important role in meeting U.S. energy needs as well as in reducing the environmental impact of power generation. Benefits include:
- Efficiency Benefits: CHP requires less fuel to produce a given energy output, and avoids transmission and distribution losses that occur when electricity travels over power lines.
- Reliability Benefits: CHP can be designed to provide high-quality electricity and thermal energy to a site regardless of what might occur on the power grid, decreasing the impact of outages and improving power quality for sensitive equipment.
- Environmental Benefits: Because less fuel is burned to produce each unit of energy output, CHP reduces air pollution and greenhouse gas emissions.
- Economic Benefits: CHP can save facilities considerable money on their energy bills due to its high efficiency and can provide a hedge against unstable energy costs.
Where does CHP make sense?
CHP is ideally suited for applications that have coincident thermal and power loads. CHP is most economical in applications that have high thermal loads and in areas where electricity costs more than $0.07/kilowatt-hour on average. CHP technology has been successfully installed in a wide variety of energy-intensive facility types and sizes nationwide, including:
- Industrial manufacturers - chemical, refining, ethanol, pulp and paper, food processing, glass manufacturing
- Institutions - colleges and universities, hospitals, prisons, military bases
- Commercial buildings - hotels and casinos, airports, high-tech campuses, large office buildings, nursing homes
- Municipal - district energy systems, wastewater treatment facilities, K-12 schools
- Residential - multi-family housing, planned communities
The CHP Partnership has targeted some of its analysis and outreach efforts to increase awareness and adoption in three strategic market sectors: dry mill ethanol production, hotels and casinos, and municipal wastewater treatment facilities, and utilities. More information about these sectors can be found on the CHP Markets page.
How are CHP projects developed?
CHP project development usually entails five distinct stages: qualification, level 1 feasibility analysis, level 2 feasibility analysis, procurement, and operations and maintenance. The Project Development page provides information, tools, and hints on each of these stages of development, as well as information about how to access the assistance of the CHP Partnership.
