Penn State Health Miton S. Hershey Medical Center

Abstract

Penn State Health Milton S. Hershey Medical Center recently completed the addition of a new Combined Heat and Power (CHP) Plant to the existing central utility plant that serves the 550-acre hospital campus. The combined heat and power system is expected to supply 54% of the hospital campus power demand, 96% of the steam load, reduce annual utility costs and improve energy supply resiliency. The project will also reduce campus carbon emissions by 83,120 metric tons, equivalent to the annual residential electric use of 27,662 people.

The CHP Plant is based on one 7.5 MW combustion gas turbine generator and one heat recovery steam generator with supplemental duct firing capability to supply 80,000 lb/hr steam. To further improve resiliency of energy supply, it incorporates load shedding and black start capability to support hospital island operation and to maintain hospital services during utility grid outages. A custom PLC-based load management system is included to manage the turbine generator output, prevent power export to utility, and to implement load shedding for hospital island operation.

The presentation will highlight the essential design features of the CHP project, such as the load management system, and lessons learned during the design and power utility interconnection approval process.
