New Haven Public Schools Combining Heat and Power

Nowadays, school districts are hard pressed to reduce operating expenses and come up with large capital outlays without jeopardizing academic standards. Connecticut’s New Haven Public Schools (NHPS) found a sure-fire way not only to reduce electricity and heating costs, but to also become energy independent and a bit greener. This district contracted with Aegis Energy Services Inc. to install 75 kilowatts (kW) of combined heat and power (CHP) systems in six of its schools.

Aegis Energy Services will install, own and maintain the CHP systems and sell back electricity and hot water to the schools at a rate less than the local utility charges. CHP, also known as a form of cogeneration, simultaneously produces usable heat and electricity from a single fuel source, in this case natural gas.

This move allows NHPS to avoid capital and operating costs and save at least $630,000 in utility costs over the 10-year contract.

Aegis Energy Services’ 75-kW units can be installed individually or combined to form larger systems. Each cogeneration module includes a natural gas-fueled engine, induction generator, microprocessor control panel, protective switchgear, and heat-recovery equipment. Each module is enclosed in a sound attenuated cover and can be installed indoors or outdoors.
