WALTHAM, Mass., July 13 /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, today estimated the Company's On-Site Utility customers will save over $17 million during the term of their agreements.

"Organizations are beginning to realize that combined heat and power (CHP) systems deliver substantial energy cost savings along with considerable environmental benefits.  However, they often do not have the necessary capital required to purchase CHP systems," explained John N.

On-Site Utility
