2 What technology can o Increase overall energy efficiency and reduce utility bill expenditures? o Reduce carbon emissions? o Increase energy reliability, decrease reliance on the grid, and support grid T&D? o Show more energy savings and reduce more emissions than comparably sized PV and wind technologies? o Support nation s energy goals and is commercially available today? The Answer? CHP 6

3 Why CHP in Hospitals? o Healthcare organizations spend > $6.5B annually o Every $1 a non-profit healthcare organization saves on energy is equivalent to generating $20 in new revenues for hospitals o For-profit hospitals can raise their earnings per share 1 by reducing energy costs just 5% o CHP systems can reduce energy costs and carbon emissions o CHP systems can maintain hospitals power and heat during manmade and natural disasters o 200+ hospitals operate CHP systems today o 7 of Top 16 U.S. hospitals use CHP according to US News 1)ENERGY STAR - 2) DOE CHP Installation Database 3)US News Honor Roll of the Nation s Top 18 Hospitals:(John Hopkins, Mass. General, Mayo Clinic, Cleveland Clinic, NY Presbyterian, NYU Langone, Indiana University) 7

4 US DOE CHP Technical Assistance Partnerships (TAPs) o U.S. DOE CHP Technical Assistance Partnerships (TAPs) originally established in 2001 by U.S. DOE and ORNL to support DOE CHP Challenge (formally known as RACs and CEACs) o Today the 7 TAPs promote the use of CHP, District Energy, and Waste Heat to Power Technologies o Strategy: provide a technology outreach program to end users, policy, utility, and industry stakeholders focused on: Market analysis & evaluation Education & outreach Technical assistance o Midwest Website: 8

10 Emerging Drivers for CHP 14 o Benefits of CHP recognized by policymakers o 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 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 Energy resiliency and critical infrastructure DOE / EPA CHP Report (8/2012) Executive Order: Report: rgy/pdfs/chp_clean_energy_solution.pdf

11 CHP Is Used at the Point of Demand 4,200 CHP Sites (2012) 82,400 MW installed capacity Saves 1.8 quads of fuel each year Avoids 241 M metric tons of CO 2 each year 87% of capacity industrial 71% of capacity natural gas fired Source: ICF International

12 Favorable Characteristics for CHP Applications o Concern about energy costs o Concern about power reliability o Concern about sustainability and environmental impacts o Long hours of operation o Existing thermal loads o Central heating and cooling plant o Future central plant replacement and/or upgrades o Future facility expansion or new construction projects o EE measures already implemented o Access to nearby renewable fuels o Facility energy champion 16

15 Typical Hospital CHP System Configurations o o o o Sizes TYPICALLY range from 100s of kws to several MWs (depending on facility size and usually below 10 MW) Common CHP prime mover types in hospitals are reciprocating engines, combustion turbines, and/or steam turbines (mostly fueled by natural gas) Most hospital CHP systems are sized for the thermal load requirements with the resulting electric power generated used to first offset the power purchased from the utility grid (excess power can be sold to the utility) CHP systems do not replace the need for emergency generator sets to meet the life critical loads of a hospital Can reduce the number and capacity of the emergency generators Can increase the total electric reliability for the hospital 19 Source: HospitalGuidebook_ pdf

16 Emergency Generators vs. CHP Systems o o o o o Emergency Generators Minimum requirement, sized to meet life critical loads Hospitals are installing larger generators to protect more and more hospital loads Diesel fueled high emissions & limited amount of stored fuel (hours versus days of operation) Not designed or capable of continuous operation for long periods of time rarely operates Financial payback only in times of emergency o o CHP Systems Sized to meet thermal or electric loads operates continuously to meet those loads Natural gas fueled low emissions o Does not replace emergency generator set for life critical loads o o o Reduces overall size and capacity of emergency generator sets Emergency generator sets become backup to the backup; much higher reliability Good financial return 20

17 CHP Benefits to Hospitals o Reduces energy costs o Increases energy efficiency, helps manage costs, maintains jobs, etc. o Reduces risk of electric grid disruptions & enhances energy reliability o Provides stability in the face of uncertain electricity prices 21

Engines Installed: 1997 / 2005 "We said, Well, if we're going to centralize it all, doesn't it make sense to do a CHP and generate our own electricity, to reduce our demand load, and then capture the heat of those engines and utilize all that for heating and/or cooling?' " Charlie Stevenson, Director of Plant Operations Northwest Community Hospital "The beauty of this CHP to him was not simply the return for the cogen system, but the fact that these savings would pay for the central energy plant too. Joe Sinclair, Ballard Engineering

20 Project Profile: Alternative Financing Jesse Brown VA Medical Center Chicago, IL Capacity: 3.4 MW Fuel: Natural Gas Prime Mover: Combustion Turbine Installed: 2003 Energy Systems Group (ESG) raised $13 million funding for design, construction, and installation of the project by creating an owner trust, which then sold bonds used for financing.

24 Project Profile: Disaster Relief, Hurricane Katrina Mississippi Baptist Medical Center Jackson, MS Capacity: 4.2 MW Fuel: Natural Gas Prime Mover: Combustion Turbines Installed: 1991 The independence provided by the CHP system allowed MBMC to continue operation relatively unaffected during Hurricane Katrina in As soon as power reliability became a factor MBMC performed a load shed, switched off of the power grid, and continued operation in turbine-only mode. MBMC was the only hospital in the Jackson metro area to remain nearly 100% operational. After approximately 50 hours, the power reliability issue was addressed and MBMC connected to the power grid and returned to normal operation. Source:

Engine Backups Installed: 2011 During the storm, the facility operated without any loss of power and, despite most of the businesses in the surrounding area being without power for several days, Danbury Hospital still had lights and heat. The CHP facility enabled the hospital to be fully functional during the storm and continued conducting business and providing the critical and necessary health care for patients.
