Other Benefits?
A system that runs every day is more reliable in an emergency than a system
that only runs when you need it.
4
Remember August 2003?• Half of NYC’s 58 hospitals suffered backup
power failures. (New York Times 8/16/03)
• Generator failures at Verizon office caused 911 gaps. (Daily News 8/17/03)
• Montefiore
Medical Center (NYC) –
site down for 5 minutes, then fully operational throughout
using the CHP system
• South Oaks Hospital (Amityville) –
Seamless transfer to CHP only
5
Remember Sandy, Lee and Irene?
• NYU downtown Manhattan campus remained almost fully operational (Sandy)
• Data centers in lower Manhattan shutdown due to flooding of oil supply for backup
generators. (Sandy)• Fonda‐Fultonville
Central School remained
operational and served as a shelter (Irene)
6
Why weren’t the backup gensets reliable?
• Some didn’t start.• Most started, but couldn’t maintain power
throughout the outage– Equipment failure– Out of fuel
7
Other Benefits?
• Societal benefits– Cleaner emissions – NOx, CO2
– Grid voltage support– Reduces need for grid infrastructure upgrade– Demand reduction –
lowers everybody‘s electric bill
– Facilities of refuge (high schools, BOCES, college campuses, etc)
– Critical infrastructure
8
Things to Consider• Thermal and electric load profiles (daily,
weekly, yearly)– The best sites are ones with:
• Coincident electric and thermal loads • Year‐round thermal loads
• How large is the electric load that must be served during grid outages
– This could be the primary driver at some sites• Hospitals• Datacenters
9
Thermal Loads• Domestic hot water• Space heating (including re‐heat)• Space cooling (absorption chiller)• Desiccant de‐humidification• Process heating/cooling• Boiler makeup‐water pre‐heat• District heating• Other (sidewalk de‐icing)
10
Other Considerations• Electric tariff structure
• In NYS, the On‐site Generation electric tariff ENCOURAGES CHP operation Monday – Friday from 8 AM to 10 PM,
• But the rest of the time electricity might be cheap enough to justify shutting down the CHP system.
• Special Interconnect requirements• Are synchronous generators allowed?• Minimum import power requirements?
• Fuel Availability
11
Reciprocating Internal Combustion Engine (RICE)
• 1.2kW up to about 5MW• Natural gas or biogas• Induction, synchronous, and inverter available• Low to medium temperature heat – can make
low pressure steam and hot water• Relatively inexpensive, but require regular
maintenance
12
Microturbines• 30kW to 200kW per unit• Inverter based• Slightly lower electric efficiency than RICE, but
higher temperature heat output (better for absorption cooling)
• Efficiency decreases with increased ambient air temperature
• More expensive than RICE but lower maintenance requirements
13
Fuel Cells• Small fuel cells (PEM) can’t do CHP (yet)• Phosphoric acid (400kW) produces medium temperature
heat –
good for hot water• Molten carbonate (300kW) produces high temperature
heat • Solid oxide (100kW) can produce high temperature heat• High electric efficiency (~40 ‐
50%)
• Still relatively expensive, but getting better• Quiet, low maintenance and high availability• Like to run flat out – don’t plan on turning them off
14
Gas Turbines
• 5 MW and up• High temperature heat recovery (steam)• High electric efficiency (~32%), but does
decrees with increased inlet air temperature

Feasibility StudiesTechnical Assistance/FlexTech
(PON 1746)
Demonstration/Deployment Program CHP Acceleration (PON 2568)
Performance ProgramsCHP Performance Program (PON 2701)Fuel Cell Incentive (PON 2157)
26
CHP Acceleration Program
• Over $20M available through the end of 2016• Systems from 50kW to 1.3MW (inclusive)• Rebate for installation of approved CHP
systems by approved vendors• RFI 2568 –
vendor application
• PON 2568 – system installation application
27
CHP Acceleration Program
• CHP vendors– Reputable equipment– All major components defined– Single point of responsibility for system design,
installation design, Min. 5 year warranty – maintenance ‐
service
– Max. 1.6 lbs NOx/MWhr– Generally capable of greater than 60% AFEU
28
CHP Acceleration Program• Site Applications Include
– Make and model of CHP system to be installed– Engineering study showing at least 60% AFEU– 30% site design– CESIR determination– Letter from gas utility stating that gas is available– Schedule showing max. of 12 months to
operation.
