President’s Executive Order 13624: 40GW of new CHP by 2020
DOE’s AMO CHP Deployment Program assists industrial, institutional, commercial, and multifamily facilities/buildings to accelerate investment in energy‐efficient CHP thereby improving competitiveness, heightening energy security, and protecting our environment. The DOE CHP Technical Assistance Partnerships (CHP TAPs) provide:•Regional CHP expertise•Fact‐based, un‐biased information on CHP:
• Technologies
• Project development
• Project financing
• Local electric and natural gas supplier interfaces
• State best practice policies
•Vendor, fuel, and technology neutral assessments of CHP viability
2
DOE CHP Technical Assistance Partnerships (CHP TAPs)
• Market Opportunity AnalysisSupporting analyses of CHP market opportunities in diverse markets including industrial, federal, institutional, and commercial sectors
• Education and Outreach Providing information on the energy and non‐energy benefits and applications of CHP to state and local policy makers, regulators, end users, trade associations, and others.
• Technical AssistanceProviding technical assistance to end‐users and stakeholders to help them consider CHP, waste heat to power, and/or district energy or microgrid with CHP in their facility and to help them through the development process from initial CHP screening to installation. www.energy.gov/chp
DOE's CHP TAPs promote and assist in transforming the market for CHP, waste heat to power, and district energy or microgrid with CHP throughout the United States. Key services include:

CHP: A Key Part of Our Energy Future Form of Distributed Generation
(DG)
An integrated system
Located at or near a building / facility
Provides at least a portion of the electrical load and
Uses thermal energy for:
– Space Heating / Cooling
– Process Heating / Cooling
– Dehumidification
CHP provides efficient, clean, reliable, affordable energy –today and for the future.

What Are the Benefits of CHP?
CHP is more efficient than separate generation of electricity and heat
Higher efficiency translates to lower operating cost, (but requires capital investment)
Higher efficiency reduces emissions of all pollutants
CHP can also increase energy reliability and enhance power quality
On‐site electric generation reduces grid congestion and avoids distribution costs
7
Emerging Drivers for CHP
8
o Benefits of CHP recognized by policymakers
o President Obama signed an Executive Order to accelerate investments in industrial EE and CHP on 8/30/12 that sets national goal of 40 GW of new CHP installation over the next decade
o State Portfolio Standards (RPS, EEPS, Tax Incentives, Grants, standby rates, etc.)
o Favorable outlook for natural gas supply and price in North America
o Opportunities created by environmental drivers
o Utilities finding economic value
o Energy resiliency and critical infrastructure

CHP Today in the United States
• 82.7 GW of installed CHP at over 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

Critical Infrastructure and Resiliency Benefits of CHP
“Critical infrastructure” refers to those assets, systems, and networks that, if incapacitated, would have a substantial negative impact on national security, national economic security, or national public health and safety.”Patriot Act of 2001 Section 1016 (e)
Applications:
o Hospitals and healthcare centers
o Water / wastewater treatment plants
o Police, fire, and public safety
o Centers of refuge (often schools or universities)
o Military/National Security
o Food distribution facilities
o Telecom and data centers
CHP (if properly configured):o Offers the opportunity to
improve Critical Infrastructure (CI) resiliency
o Can continue to operate, providing uninterrupted supply of electricity and heating/cooling to the host facility

Resilient University Microgrids in Super-storm Sandy The College of New Jersey (NJ) – 5.2 MW CHP
◦ “Combined heat and power allowed our central plant to operate in island mode without compromising our power supply.” ‐ Lori Winyard, Director, Energy and Central Facilities at TCNJ
Fairfield, University (CT) – 4.6 MW CHP◦ 98% of the Town of Fairfield lost power, university only lost power for a brief period at
the storm’s peak◦ University buildings served as area of refuge for off‐campus students
Stony Brook University (LI, NY) – 45 MW CHP◦ < 1 hour power interruption to campus of 24,000 students (7,000 residents)
NYU Washington Square Campus (NY, NY) – 13.4 MW CHP
Princeton University (NJ) – 15 MW CHP◦ CHP/district energy plant supplies all heat and hot water and half of the electricity to
campus of 12,000 students/faculty◦ "We designed it so the electrical system for the campus could become its own island in
an emergency. It cost more to do that. But I'm sure glad we did.“ – Ted Borer, Energy Manager at Princeton University [see Wednesday am Ted Talk]

Screening QuestionsWhat makes a “good” CHP project?
Do you pay more than $.06/kWh on average for electricity (including generation, transmission and distribution)?
Are you concerned about the impact of current or future energy costs on your business?
Are you concerned about power reliability? Is there a substantial financial impact to your business if the power goes out for 1 hour? For 5 minutes?
Does your facility operate for more than 6000 hours per year?
Do you have thermal loads throughout the year (including steam, hot water, chilled water, hot air, etc.)?
21
Screening QuestionsWhat makes a “good” CHP project?
Does your facility have an existing central plant? Do you expect to replace, upgrade, or retrofit central
plant equipment within the next 3‐5 years? Do you anticipate a facility expansion or new
construction project within the next 3‐5 years? Have you already implemented energy efficiency
measures and still have high energy costs? Are you interested in reducing your facility's impact on
the environment? Do you have access to on‐site or nearby biomass
resources (i.e. landfill gas, farm manure, food processing waste, etc.?

Proposed Packaged CHP Accelerator
Purpose: to increase the penetration of CHP in the commercial building and manufacturing sectors estimated at ~ 85GW of technical potential:◦ Targeted at packaged system requirements of 10 MW or below◦ Designed to reduce perceived risks to both end users and CHP system
vendors and speed install time
◦ Builds off of the NYSERDA packaged CHP program
CHP Accelerator has two primary parts:◦ National electronic Catalog (eCatalog) of approved packaged CHP
systems by pre‐qualified CHP system vendors◦ Market Mover Partners providing market engagement for CHP
programs at the state, local and utility level, from outreach efforts to incentive programs
