Penn State Health Milton S. Hershey Medical Center has recently successfully completed the addition of a new Combined Heat and Power (CHP) Plant to the existing central utility plant serving the 550-acre hospital campus. The installed combined heat and power system is expected to supply 54% of the hospital campus power usage and 96% of the steam usage, while providing the hospital with the benefit of reduced annual utility costs and improved energy supply resiliency. The project would 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 to be conducted by the design engineer will highlight the essential design features of the CHP project such as the load management system, and lesson learnt through the project including the process of seeking power utility interconnection approval.
