Club Fit Saves With On-Site Utility by American DG Energy

Fitness Facility Reduces Costs While Lowering CO2 Emissions

BRIARCLIFF MANOR, N.Y., Sept. 2 /PRNewswire-FirstCall/ -- American DG
Energy Inc. (OTC Bulletin Board: ADGE), a leading On-Site Utility, offering
clean electricity, heat, hot water and cooling systems, today announced that
Club Fit, a premier health and fitness facility, located in Briarcliff Manor,
New York, saved thousands of dollars on it's energy bills and lowered its CO2
emissions with an On-Site Utility in the first year of operation.
For the past year, Club Fit has received a substantial portion of its
energy directly from an On-Site Utility by American DG Energy. With the
On-Site Utility, American DG Energy produces energy in the form of electricity
and hot water at Club Fit's facility and sells it to Club Fit at a price lower
than their local energy utility. Club Fit pays for the energy they use, not
any capital or operating costs. The energy is produced with small-scale,
combined heat and power (CHP) equipment located at the property site, but
owned and operated by American DG Energy.
"With the On-Site Utility we've greatly reduced our energy costs and
lowered greenhouse gas emissions at the same time," stated Bill Beck, Vice
President of Club Operations at Club Fit. "Because American DG Energy takes
care of the equipment, we don't have to think about it. We just have to pay
our lower energy bill."
The On-Site Utility lowers Club Fit's emissions up to 578 tons of CO2 gas
each year, the equivalent of planting 158 acres of trees or eliminating the
emissions of 98 cars.
On-Site Utility
American DG Energy sells the energy produced on-site from a CHP system to
an individual property as an alternative to the outright sale of energy
equipment. On-Site Utility customers only pay for the energy produced by the
CHP system and receive a guaranteed discount rate on the price of the energy.
All system capital, installation and operating expenses are paid by American
DG Energy. All system installation, operation and support are handled by the
Company as well.
