WALTHAM, Mass., Aug. 15, 2012 /PRNewswire/ -- American DG Energy Inc. (NYSE MKT: ADGE), a leading On-Site Utility, offering clean electricity, heat, hot water and cooling solutions to hospitality, healthcare, housing and athletic facilities, today announced that it has reached an agreement to provide an on-site energy solution to the Cumberland County Jail in Portland, Maine. Under the terms of the agreement, Cumberland County Jail will receive a portion of its energy from two 75 kW combined heat and power systems (CHP). The systems will be owned and operated by American DG Energy. American DG Energy will produce space heat, domestic hot water and electricity within the Cumberland County Jail complex. The CHP systems will offset 584 tons of carbon annually. This annual carbon savings is equal to removing 1044 vehicles from the road each year. Cumberland County Jail will pay only for the energy used by the facility and avoid all capital, installation and operating costs of the systems. The agreement will provide American DG Energy with a revenue value of approximately $2,400,000 over the 15 year contract. Built in 1994, the Cumberland County Jail had been looking at cost saving measures and realized that American DG Energy could provide relief on energy costs without spending any money. The corrections Division's 200 staff members provide care, custody and control of over 500 inmates.
