As part of an initiative to reduce their carbon footprint, improve energy efficiency, reduce utility expenses, and provide backup power to systems in its national network of facilities, The United States Department of Veteran Affairs implemented Capstone microturbine technologies at their Ann Arbor Medical Center campus. The medical center campus encompasses the hospital, outpatient clinics, community living center, a radiation therapy facility, two research buildings, five administrative outbuildings, two parking garages, and an energy center. Because the demand of power for critical loads in hospitals can often be a matter of life or death, on-site energy generation is crucial. A combined heat and power (CHP) system was installed using a Capstone C1000 microturbine and delivers electricity and steam to the 1.1-million-square-foot Ann Arbor VA facility using clean-burning natural gas supplied by the local utility. The Capstone C1000 operates 24/7 in parallel with the local electric utility, reducing the hospital’s electric bill. During power outages, the microturbine works with the hospital’s emergency diesel generators to power less critical loads, improving the campus’ resilience overall. Its efficiency is saving approximately US $370,000 annually for the medical center.
