Cogeneration System Now Operating at North Hill

Independent Living Community Receives Energy Producing Equipment at No Cost

NEEDHAM, Mass., Oct. 28 /PRNewswire/ -- 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 cogeneration system at North Hill, an independent living community in Needham, Massachusetts.  The Company estimates the total revenue from this project to be $1.4 million over the fifteen-year agreement.

Through its On-Site Utility energy solution, American DG Energy generates clean energy in the form of electricity, space heat and hot water at North Hill and sells it to the facility at a price lower than the local energy utility.  North Hill pays for the energy used by the property and avoids all capital, installation and operating costs.  The energy is produced with a 75 kW cogeneration system, located at the property site but owned and operated by American DG Energy.  Since the Company also handles all service, maintenance and repair, North Hill does not need any manpower to support the energy equipment.

North Hill's Director of Plant Services, Harry Goodale, has been working endlessly to reduce utility cost by analyzing North Hill's efficiency mix throughout the 500,000 plus square foot campus.  The location selected for the natural gas powered cogeneration system is that which generates the highest demand for electricity and hot water - the building containing the skilled nursing facility, commercial laundry and main kitchen.

"Since the cogeneration system began running in August, I have walked by our five 150 gallon hot water heaters and 1.5m btu boilers many times and not once have I heard them kick on," said Mr. Goodale.  "Also, with no capital investment and all the maintenance provided by American DG Energy, it's a homerun any way you look at it."

Cogeneration, also called combined heat and power or CHP, systems offer considerable environmental benefits when compared with purchased electricity and on-site-generated heat from a boiler.  By capturing and utilizing heat that would otherwise be wasted from the production of electricity, Cogeneration systems require less fuel than equivalent separate heat and power systems to produce the same amount of energy.  Because less fuel is combusted, greenhouse gas emissions, such as carbon dioxide, as well as air pollutants like nitrogen oxides and sulfur dioxide, are reduced.

Due to the high-efficiency of the cogeneration system installed at North Hill, American DG Energy estimates the emissions of the property will be reduced by 225 tons of carbon dioxide each year.
