What is Combined Heat and Power (CHP)? A method of simultaneously generating thermal energy (heat) and electricity Fuel agnostic Often in an integrated system Not a specific technology, but an application of currently available technologies Typically composed of mechanical components manufactured in the United States Flexible and resilient Source: ACEEE -
How CHP Works Source:
Increased Efficiency & Reduced Emissions
Applications for CHP Large CHP (>20 MW) Industrial sites Colleges and universities District energy systems Mid-Size CHP (1-20 MW) High-growth industrial applications Manufacturing and assembly plants Institutional, military and government facilities Large commercial sites District energy systems Small CHP (<1 MW) Source: DOE Office of Energy Efficiency and Renewable Energy

CHP is a Cost Effective Electricity Resource Source:
Benefits of CHP Uses existing, proven technology Improve system efficiency Diversify energy supplies Reduce emissions Increase business competitiveness Enhance resilience/energy security Source: DOE Combined Heat and Power: Effective Energy Solutions for a Sustainable Future, 2008
Increasing the Security and Resilience of the Energy System
Generally refers to capturing waste heat that a building, industrial site or power plant is already emitting Use recovered heat to generate clean thermal energy (hot water, steam, chilled water) or clean electricity. Opportunity to vastly improve industrial energy efficiency, competitiveness of U.S. industrial sector, and provide a source of pollution-free energy Opportunity: Waste Heat Recovery
How Can it be Used? Heating and cooling buildings Heating and cooling processes Heating domestic hot water Snowmelt Generate electricity Other thermal process needs Source: DOE -
Who is Encouraging CHP and Recovery of Waste Heat? U.S. Department of Energy U.S. Environmental Protection Agency U.S. Armed Forces U.S. Energy Information Agency International Energy Agency International District Energy Association American Council for an Energy Efficient Economy
