American DG Energy is now operating a clean energy system at Sterling Center YMCA, a branch of the North Shore YMCA in Massachusetts, US.
The c system operated by American DG at the Sterling Y is a highly efficient, 75 kW CHP system, which generates electricity, space heat, hot water and pool heat at the property.
With the company’s ‘on-site utility’ concept, the Sterling Y only pays for the energy used by the facility and avoids all capital, installation, operating and maintenance costs of the energy system.
In addition, the energy produced by the system is priced lower than that from the local utility, so the Sterling Y began saving on energy costs immediately upon system start-up.
It is expected to save over US$200,000 during the term of the agreement.
CHP systems are a cleaner energy option, offering considerable environmental benefits, when compared with purchased electricity from the grid and site-generated heat from a boiler.
By capturing and utilizing heat that would otherwise be wasted from the production of electricity, CHP 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 sulphur dioxide, are also reduced.
In the case of the Sterling Y, the CHP system could reduce the property’s emissions by up to 300 tonnes of carbon dioxide annually.
