21 May 2010 – Clean energy company American DG Energy has reached an agreement to supply Sterling Center YMCA, a branch of the North Shore YMCA located in Beverly, Massachusetts, US. 
Under the agreement, the Sterling YMCA will receive a significant portion of its energy from a 75 kW CHP system, which will be owned and operated by American DG Energy. 
Sterling YMCA will receive a discount on the energy produced by the CHP system and reduce its carbon emissions by up to 330 tonnes per year. The value of the agreement to American DG is US$2 million.
American DG Energy will produce clean energy in the form of electricity, space heat, hot water and pool heat at the Sterling Center YMCA, and sell it to the center at a price lower than the local energy utility.
The Sterling Center will pay only for the energy used by the facility and will avoid all capital, installation and operating costs. 
The energy will be produced with small-scale CHP equipment, located at the property site but owned and operated by American DG Energy, which will also handle all service, maintenance and repair activities.
