CHP to Provide Hot Water and Air Conditioning for Long Island School District
Cogeneration turns an otherwise lost energy source into efficient heating and cooling
PORTSMOUTH, N.H. — Four FlexEnergy GT250S microturbines will become an integral part of a comprehensive energy savings project for the Longwood Central School District in Long Island, New York. The microturbines will include an integrated hot water cogeneration module to allow for a simple mechanical connection to multiple-facility hot water systems, as well as absorption chilling, reducing equipment footprint and facilitating quiet, safe, and reliable operations for combined heat and power (CHP). FlexEnergy’s Supervisory Control Master (SCM) will control two GT250S microturbines installed at the high school and an additional SCM will control two GT250S turbines at the middle school, managing the turbines for import control with dual mode capabilities to operate uninterrupted under grid isolated conditions when utility power is not available.
FlexEnergy designed and sold the microturbines and accompanying Supervisory Control Masters to the school district through its channel partner, MDP Energy of Long Island. Wiedersum Associates Architects consulted with MDP Energy on the cogeneration portion of the $21 million capital improvement/energy bond project, $8 million of which is earmarked for cogeneration and related equipment. Longwood Central School District is adding 300 tons of air conditioning as part of this capital bond project. The Flex turbines alone will produce the equivalent of 120 tons of air conditioning through an absorption chiller by capturing waste heat.
