(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 its energy systems generated nearly 25 Million kWh of total energy in the second quarter of 2013. This represents approximately a 55% increase over the same period in 2012 and is the highest second quarter production in the company's history. American DG Energy owns and operates combined heat and power (CHP) systems, chillers, heat pumps and boilers that are now producing energy in the form of domestic hot water, space heat and electricity. Customers only pay for the energy used at a guaranteed lower cost than that provided by local utilities and avoid all associated capital, installation, and operating costs. CHP systems are a cleaner energy option that offer significant environmental benefits. Heat that would otherwise be wasted by typical electricity production is captured and utilized as domestic hot water, space heat and electricity. Utilization of CHP systems greatly reduce carbon emissions output, sulfur dioxide output is nearly eliminated and nitrogen oxide emissions are dramatically reduced creating a greener environment.
