OverviewBeth Israel Medical CenterEngine Generator forCOMBINED HEAT AND POWER FOR: Health ServicesBeth Israel Medical Center is a 212 bed fullservicecommunity hospital in Brooklyn, NY. A250 kW co-generation system was installed on thebuilding’s rooftop in an effort to reduce relianceon the public power grid and promote energyefficiency throughout the medical center campus.The ApplicationThe combined heat and power (CHP) system atBeth Israel Medical Center consists of one KraftEnergy / MAN rich burn engine (KMGR-250-4SH) cogeneration unit capable of a totalelectrical output of 250 kW. Thermal output fromthe unit will be used to supply heat to the boilerreturn loop. A dump radiator will reject anyunneeded thermal energy.The site’s electric demand is sufficient to keep thesystem operating at or near its rated capacity on acontinuous basis. Annually the system isanticipated to displace 2,021,860 kWh anddisplace 118,530 therms of gas through heatrecovery. Annual fuel consumption waspreviously 224,180 therms.The CHP system for Beth Israel Medical Center isinstalled in a weatherized container located on theroof of one of the site’s buildings.Quick FactsLocation:Brooklyn, NY(Con-Edison)CHP Equipment:Kraft KMGR-250-4SHEngine GeneratorInstallation Date:Heat Recovery Application:2012 Space HeatingOperating Experience:Beginning 2012Type of Fuel:Natural GasGenerating Capacity: Annual Efficiency:250 kW 79%“Hospitals face increasing pressure to managetheir energy risks…(this CHP system) not onlyshowcases our expertise in the healthcaresector, but serves as a powerful model for otherhospital campuses.”- Stewart A.

Beth Israel Medical CenterCHP System and EquipmentHeat is recovered as hot water from both the engine jacket and exhaust at a supply temperature of 195°F. Aheat exchanger separates the engine coolant from the boiler return loop. Any excess heat that is produced willbe rejected through an external radiator.ToBuildingLoadsExhaust gas toatmosphereExhaustHeatExchangerNatural Gasfrom UtilityGeneratorElectricityto facilityHX-1Key__ ExhaustDumpRadiator__ Natural Gas__ ElectricityFromBuildingLoadsEconomics and Environmental Benefits__ Hot WaterThe CHP system at Beth Israel Medical Center is expected to operate at an annual efficiency of 79%(LHV) and achieve a 95% or better availability. CHP efficiency is usually twice that of conventionalutility power.
