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 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. www.energy.gov/chp

What Are the Benefits of CHP?

▪ CHP is more effic icient than separate generation

  • f electricity and heating/cooling

▪ Higher efficiency translates to lo lower operating costs (but requires capital investment) ▪ Higher efficiency reduces emis issions of pollutants ▪ CHP can also increase energy relia liabil ility and enhance power quality

slide-10
SLIDE 10

Emerging National Drivers for CHP

▪ Benefits of CHP recognized by policymakers

  • State Portfolio Standards (RPS, EEPS), Tax Incentives,

Grants, standby rates, etc.

▪ Favorable outlook for natural gas supply and price in North America ▪ Opportunities created by environmental drivers ▪ Utilities finding economic value ▪ Energy resiliency and critical infrastructure

The State of CHP

slide-12
SLIDE 12

CHP Today in the United States

  • 82.6 GW of installed CHP at nearly

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

CO2 compared to separate production

Appli licatio ions: ▪ Hospitals and healthcare centers ▪ Water / wastewater treatment plants ▪ Police, fire, and public safety ▪ Centers of refuge (often schools or universities) ▪ Military/National Security ▪ Food distribution facilities ▪ Telecom and data centers

CHP CHP (if properly configured):

▪ Offers the opportunity to improve Critical Infrastructure (CI) resiliency ▪ Can continue to operate, providing uninterrupted supply of electricity and heating/cooling to the host facility
