The award is given for ‘superior performance of CHP systems’, the agency said.
Winning installations must use at least 10% less fuel than state-of-the-art separate heat and power generation; be affiliated with the EPA’s CHP Partners scheme; have a minimum of 12 months and 5000 hours of measured operating data beginning within 14 months before the date of application; and operate within permitted emission limits.
Of the winning plants, three are located at medical centres, while the fourth is sited at an Army National Guard facility where mission support helicopters are housed and maintained. In addition to CHP, two of the facilities also feature on-site solar photovoltaic (PV) systems.
The winners were: South Oaks Hospital in Amityville, New York; the University of Maryland Upper Chesapeake Medical Centre in Bel Air, Maryland; the University of Massachusetts Medical School in Worcester, Massachusetts; and the Maine Army National Guard in Bangor, Maine.
The EPA said the four systems together save an estimated $4 million per year.
‘Today’s award winners demonstrate how CHP can save money and reduce pollution, a real win-win for the bottom line and the environment,’ said Janet McCabe, acting assistant administrator for the EPA’s Office of Air and Radiation. ‘On-site power generation, like CHP, can also strengthen our nation’s electrical infrastructure.’
