Portsmouth, New Hampshire - (Business Wire) - June 26, 2002 - Environmental
Power Corporation (OTCBB:POWR), a leader in the renewable energy industry since
1982, has been named as 15th among New Hampshire's top 100 public companies by

Joseph E. Cresci, Chairman and Chief Executive Officer of POWR, stated, "We are
honored to be recognized by BusinessNH Magazine as a leading New Hampshire
company. We are also pleased that POWR advanced in the rankings. Even though
these are tough economic times, our waste coal operations achieved record levels
of output which added another successful year to our continued record of
profitability."

realize the growth potential associated with our acquisition of Microgy
Cogeneration Systems, Inc. We now hold the exclusive North American license for
a highly efficient anaerobic digestion technology which literally converts

electricity and concurrently acts as a pollution control system that reduces
surface and ground water contamination on the farms and surrounding areas."
