DOE CHP Technical Assistance Partnerships (CHP TAPs) End User Engagement • Partner with strategic End Users to advance technical solutions using CHP as a cost effective and resilient way to ensure American competitiveness, utilize local fuels and enhance energy security. CHP TAPs offer fact-based, non-biased engineering support to manufacturing, commercial, institutional and federal facilities and campuses. Stakeholder Engagement • Engage with strategic Stakeholders, including regulators, utilities, and policy makers, to identify and reduce the barriers to using CHP to advance regional efficiency, promote energy independence and enhance the nation’s resilient grid. CHP TAPs provide fact- based, non-biased education to advance sound CHP programs and www.energy.gov/chp policies. Technical Services • As leading experts in CHP (as well as microgrids, heat to power, and district energy) the CHP TAPs work with sites to screen for CHP opportunities as well as provide advanced services to maximize the economic impact and reduce the risk of CHP from initial CHP screening to installation. 3

What Are the Benefits of CHP? CHP is more ef e efficien ent t than separate generation of electricity and heating/cooling Higher efficiency translates to low ower o operatin ing c costs (but requires capital investment) Higher efficiency reduces e es emiss ssions s of pollutants CHP can also increase energy r y reliability a y and resiliency y and enhance power quality On-site electric generation can red educe g e grid congestion on and avoid distribution costs. 6
Common CHP Technologies and Capacity Ranges 7
CHP in the U.S. Represents a Variety of Fuels, Technologies, Sizes, and Applications Industrial Insti titu tutional Utility S Scale Comme mercial Reside dential 8
CHP Today in the United States • 81.3 GW of installed CHP at more than 4,400 industrial and commercial facilities • 8% of U.S. Electric Generating Capacity; 14% of Manufacturing • Avoids more than 1.8 quadrillion Btus of fuel consumption annually • Avoids 241 million metric tons of CO 2 compared to separate production 9
