Conventional Power Generation
Reliability
• Mississippi Baptist
Medical Center
(Jackson, MS) –
Hurricane Katrina
• Danbury Hospital
(Danbury, CT) –
Superstorm Sandy
Economic Benefits – TECO
(Houston) • 48 MW natural gas
system
• Combustion turbines
• Installed 1980, updated 2010
• 1,000 jobs in recent construction
• $200 million savings/
15 years

CHP Capacity - Hospitals
• Among most energy-
intensive buildings in U.S.
• Consumes > 8% of total
energy used in U.S.
commercial buildings
• Spends more than $5-billion
annually on energy

Factors to Consider
• Economic benefits of CHP
• Energy efficiency competes with clinical equipment for capital
• Electric reliability needs
• Oversized emergency generator sets
• Environmental goals
Danbury Hospital (Connecticut)
Typical Hospital CHP System
Configurations • Small to mid-size
• Typically fueled by natural gas
• Sized for thermal load
• Do not replace emergency generators to meet “life critical loads”
Gundersen-Lutheran Hospital
Emergency Generators
• Sized to meet “life
critical loads”
• Used during emergency
events
• Diesel fuel
• Financial payback only
in times of emergency
Emergency Generators vs.
CHP Systems
CHP Systems
• Sized to meet thermal
or electric loads
• Continuous operation
• Natural gas
• Good financial return
Why More Hospitals Do Not Invest in CHP • Economics not right
• Competing for capital and attention
• Competing for space
• Lack of knowledge
• Utility barriers
• Permitting
University Medical Center (Princeton, NJ)
Policy Priorities
• Financing
• Markets
• Education
