Hospital saves money and secures emergency power

Cogeneration keeps focus on life-saving care

Hospital saves money and secures emergency power

Inside a hospital, every dollar spent on heating and cooling is a dollar less spent caring for patients. That was the conclusion reached by Boston Medical Center (BMC) in Massachusetts. Local Cat® dealer Milton Cat recently installed a cogeneration natural gas installation at their facilities, using waste heat from G3520C generator sets to provide hot water and ambient heating.

By delivering both heat and power from the same source, the systems reduce site emissions and reduce total cost of ownership, saving money that can be better directed toward patient care.

The hospital values the cogeneration systems for another reason: they offer critical backup power in case of emergency. The systems are flexible and provide essential and reliable power that keeps the lights on and sustains the ability of the hospitals to provide services.



“During Hurricane Katrina and Superstorm Sandy, hospitals without cogeneration capability were forced to evacuate, because they couldn’t support patient care needs,” says Bob Biggio, vice president of facilities and support services at BMC. “Those that do have cogen can continue operations.”

Thanks to Milton Cat, BMC expects to save $1.5 million in energy costs each year, while making their facilities cleaner, safer, and more reliable.

G3520C Gas Generator Set

From natural gas-fueled combined heat and power (CHP) systems and emergency power for facilities, to renewable biogas energy to support the local grid, or electricity generated from coal mine gases, Caterpillar has a wide range of reliable gas power solutions.

Cogeneration/Combined Heat & Power (CHP)


Many industrial facilities such as manufacturing plants, refineries, and regional district heating plants; or commercial facilities such as resorts, shopping malls, high-rise office buildings, universities, data centers, and hospitals, can reduce operating costs by implementing a Cat® CHP system (also known as cogeneration) using clean pipeline natural gas as a fuel source.
