WALTHAM, Mass., Aug. 9, 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, is now operating a combined heat and power system (CHP) at DoubleTree Hotel in Tarrytown, New York. The revenue value of the agreement to the Company is $2 million over the 15 year term. The highly efficient 100kW CHP system, is owned and operated by America DG Energy and is now producing energy in the form of electricity, space heat and domestic hot water. DoubleTree opted for the Company's On-Site Utility solution and will only pay for the energy used and avoid all capital, installation and operating costs. CHP systems are a cleaner energy option, offering considerable environmental benefits when compared with purchased electricity from the grid. By capturing and utilizing heat that would otherwise be wasted from the production of electricity, CHP systems require less fuel while producing the same amount of energy. Using the EPA CHP Partnership emissions calculator, DoubleTree's utilization of a CHP system will reduce their carbon emissions by approximately 403 tons per year, or the equivalent of planting 75 acres of forest annually. DoubleTree Tarrytown is a 247 room full service, upscale property and was recently awarded the TripAdvisor Certificate of Excellence Award. With the operation of an On-Site Utility, they are now also contributing to the quality of the environment with their reduction in carbon emissions.
