Research Project Summary Information

St Elizabeth Medical Center CHP(15923)

St. Elizabeth Medical Center


The St. Elizabeth Medical Center campus is comprised of several buildings, totaling approximately 556,000 square feet. In addition to the 201 bed Medical Center (hospital), the campus houses a College of Nursing and a School of Radiology. Many of the buildings date to 1917. The campus consumes approximately 12,000 MWhr of electricity per year and over 77,000 MMBtu of natural gas for space heating and hot water. All thermal uses on campus are served by a steam distribution system with steam headers located in an old boiler house, and new boilers (9 years old) located in a nearby new boiler house.

Project Description

Three 770 kW Caterpiller gensets will be installed in the old boiler house along with three-way catalyst emission reduction systems and steam heat recovery packages. Steam produced by the gensets will be provided to the steam distribution system. The existing boilers in the new boiler house will be used to satisfy the additional thermal requirements in the colder months. A new absorption chiller will be installed to provide cooling in the summer.


The CHP system will provide an additional level of electric supply redundancy and reliability, giving the medical center the most reliable electric supply of any hospital in the region. The CHP system is expected to provide approximately 8,300 MWhr of electricity per year, approximately 41,000 MMBtu of steam per year, and 8,500 MMBtu (714,000 ton-hr) of cooling per year. The system will be operated in a thermal load following mode. Any excess electric energy will be sold to the local utility under the utility’s SC06 tariff.
