American DG Energy, Inc. - Special/M&A Calls

American DG Energy Inc. announced agreements to provide green energy solutions to The Forest Hills, a 120-unit Co-operative, located in Queens, New York. In an effort to conserve energy and reduce costs, The Forest Hills has selected American DG Energy to install a 100 kW combined heat and power (CHP) energy system and a 200-ton natural gas engine driven chiller at their property. The value of the deals to American DG Energy is $2.81 million. American DG Energy is installing a new 200-ton natural gas engine driven chiller at The Forest Hills to replace its old steam chiller. The old steam chiller, which was original to the 45 year old building, cost The Forest Hills tens of thousands of dollars annually to maintain and was an inefficient provider of chilled water and space cooling for the property. The new 200-ton natural gas engine driven chiller, having greater capacity than the old chiller, will generate more chilled water. As a result, The Forest Hills will also be able to decommission two old steam boilers, already at the end of their useful life. Instead of purchasing the new chiller, The Forest Hills opted for an On-Site Utility by American DG Energy. The Forest Hills will pay only for the energy it uses and will avoid additional operating costs. American DG Energy will handle all service, maintenance and repair. As a result, The Forest Hills will not need any manpower to support the equipment. In addition to installing the chiller, American DG Energy is installing a 100 kW CHP system at The Forest Hills. The CHP system will provide green energy in the form of electricity and hot water for space heating and domestic hot water use. The Forest Hills opted to purchase the CHP system, but has selected American DG Energy to operate and maintain the system.
