CHP Demonstration Project :Long Island Jewish Medical Center (ST7324-1)

WSP Flack & Kurtz, Inc.


The Long Island Jewish Medical Center is an 829 bed non-profit teaching hospital located on a 48-acre campus in New Hyde Park, NY. The campus contains approximately one million gross square feet of existing area and is beginning a twenty-year expansion program, which will expand the facility to a total of 1.9 million square feet. The Long Island Jewish Medical Center campus is currently served by a single central plant that produces steam and chilled water for distribution to the campus. As part of the upcoming expansion, the existing central plant will be decommissioned and will be replaced by a new, state of the art, facility designed to meet the campus heating and cooling load requirements.

Project Description

The CHP System uses two natural gas fired, reciprocating engine driven, electric generating units rated at 1,400 kW each. The electric power generated by the engines will be used solely to power the central plant's cooling and steam generating systems and their respective auxiliary components, including all the pumps, cooling towers, electric chillers, boilers, and fans. Thermal energy will be recovered from each of the engine blocks and from a heat recovery silencer on each of the engine's exhaust. The recovered heat will then be used to preheat the steam system condensate returning from the campus and to drive a single stage absorption chiller. Long Island Jewish Medical Center is partially located in the electric service territory of Consolidated Edison Company of New York, Inc. (Con Edison).


The site requires continuous distribution of steam and cooling energy throughout the year. The combination of the load profile and the extended hours of operation will allow an efficient system to create a large magnitude of savings. Technology transfer and publicity emphasizes wide dissemination of the project results. This project is forecast to provide peak load reduction of approximately 2.8 MW, and result in over $600,000 in annual net annual energy savings for the host site facility. It is forecast that the CHP System will have an overall annual fuel conversion efficiency of 86%.

Project Results

The actual cost of construction of the CHP system was $6.7 million, and it is saving $1.2 million per year. It eliminates the emission of 3,000 tons of carbon dioxide per year, which is the equivalent of taking 400 cars off the road. The CHP system began operation in July 2008; performance data is publicly-available at
