WALTHAM, Mass., Jan. 19, 2011 /PRNewswire/ -- American DG Energy Inc. (NYSE Amex: ADGE), a leading On-Site Utility, offering clean electricity, heat, hot water and cooling solutions to hospitality, healthcare, housing and athletic facilities, today announced it is now operating six energy systems at Stevens Institute of Technology, a premier technological university, located in Hoboken, NJ.

American DG Energy currently owns and operates four combined heat and power (CHP) systems and two natural gas chillers at five separate buildings on Stevens' campus. The Company added four of these energy systems during the fourth quarter of 2010.  Additionally, the Company has two CHP systems, currently under construction at the university, that are expected to begin operating during the first quarter of 2011.

"Stevens fits our roll out strategy of obtaining customers with large portfolios of properties that are good On-Site Utility candidates," said John N. Hatsopoulos, Chief Executive Officer of American DG Energy.  "We began with one system and have extended our reach across the campus as our On-Site Utility energy solution has proven it provides both economic and environmental benefits to the university."

On-Site Utility

American DG Energy sells the energy produced from an onsite energy 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 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.
