American DG Energy Operates Onsite Energy System at NY Housing Complex

BROOKLYN, N.Y., May 4 /PRNewswire-FirstCall/ -- American DG Energy Inc. (NYSE Amex: ADGE), a leading OnSite Utility, offering clean electricity, heat, hot water and cooling solutions to hospitality, healthcare, housing and athletic facilities, is now operating a 500 kW onsite energy system at Linden Plaza Preservation LP, a 1,500-unit, low-income housing complex.  Because Linden Plaza opted for the Company's On-Site Utility energy solution, the energy system, comprised of five 100 kW combined heat and power (CHP) units, was provided at no cost to the housing complex.

American DG Energy operates an onsite energy system which generates clean energy in the form of electricity and heat for domestic hot water at Linden Plaza.  The energy is produced with small-scale, CHP equipment, located at the housing complex but owned and operated by American DG Energy.  Taking advantage of the Company's On-Site Utility, Linden Plaza pays only for the energy the property uses and avoids all capital, installation and operating costs.  American DG Energy also handles all service, maintenance and repair of the energy system; therefore, Linden Plaza does not need any manpower to maintain the equipment.

On-Site Utility

American DG Energy sells the energy produced on-site from a combined heat and power system to an individual property as an alternative to the outright sale of energy equipment.  On-Site Utility customers only pay for the energy produced by the CHP system and receive a guaranteed discount rate on the price of the energy.  All system capital, installation and operating expenses are paid by American DG Energy.  All system installation, operation and support are handled by the Company as well.
