Bradley International Airport in Windsor Locks, Connecticut has
a central energy plant which provides electricity, heating and
cooling for the main passenger terminals at the airport. The
facility has been in operation since 2002 and features four
Waukesha engine-generators. The engines were supplied by Dresser
Waukesha’s distributor Kraft Power Corporation of Woburn, Mass.
Byproduct waste heat is used for heating and to power a 500-ton
Trane single-stage hot water absorption chiller, which supplies

facility started the process to add the fourth engine, a
Waukesha APG2000, rated at 1.9 MWe output natural gas-fired
internal combustion engine (IC) and heat recovery hot water
boiler. 800°F exhaust from the new engine and 1200°F exhaust
heat from the existing IC engines is used to generate 220°F hot
water used by the airport. This cogeneration plant was
constructed in one year, within an existing building originally
used for food preparation by the airli
