Saint Francis Hospital Thermal Energy Storage/Cogeneration Plant

Opened in 1960, Saint Francis Hospital has developed into a 1000+ bed healthcare facility providing full adult and child health services.  To address the growing healthcare needs of the region, the hospital planned to construct a new addition and needed to increase the load capacity of the central plant to properly serve the addition and the existing facility.

Studies of the local utility rate structures revealed the hospital could save energy, reduce costs, and reduce its carbon footprint through a combined system of thermal energy storage and cogeneration.

WTA provided MEPF engineering design for the new thermal storage system, which was based on the ice on coil external melt principal and a co-generation system.

Additionally, WTA provided commissioning serves, helped to develop the operating sequences, and assisted with operator training.  WTA also played an instrumental role during construction and system start up.
