FOR IMMEDIATE RELEASE

        ENVIRONMENTAL POWER CORPORATION TO PROVIDE WISCONSIN FARMERS WITH
               PROFIT-GENERATING SOLUTION TO ANIMAL WASTE PROBLEM

           MANURE TO PRODUCE RELIABLE, COST-EFFECTIVE ELECTRICITY FOR
                            WISCONSIN PUBLIC SERVICE

PORTSMOUTH, NH, JULY 11, 2002 - Environmental Power Corporation (OTCBB: POWR), a
leading provider of environmental solutions and renewable energy, announced that
it has signed letters of intent with six farms in the Green Bay area of
Wisconsin to build an anaerobic digester system on each site. The systems, which
will provide a profit-generating solution to environmental issues associated
with animal waste and provide peak electric power to Wisconsin Public Service
Corporation, are expected to be operational by August 2003.

Environmental Power recently obtained the exclusive North American license for a
highly efficient anaerobic digestion technology - a method of producing
renewable energy generated by methane gas extracted from animal wastes - through
its acquisition of Microgy Cogeneration Systems, Inc., now a company subsidiary.
The methane will be used to produce approximately 10 megawatts of peak power at
electric generating facilities to be constructed on the farms and operated by
Environmental Power.

Signing of the letters of intent is the second major step in bringing the
systems online. The company already has signed a 15-year agreement to provide
peak power to Wisconsin Public Service Corporation. The facilities to be
constructed on the farms will generate an estimated two-thirds of the
electricity required under the contract. Company officials expect additional
farms to sign on in the near future, providing the remainder of the power
required under the contract.

The letters of intent signed by the farms are conditioned on their completion of
technical due diligence and project financing. The engineering and construction
phase of the project are expected to begin immediately after those steps are
completed.

"The fact that these farms have signed on so quickly to use our technology
demonstrates both the urgency farmers place on the resolution of this serious
environmental issue and the desirability of the solution offered by
Environmental Power," said Donald A. Livingston, president and chief



operating officer of Microgy. "Rather than incurring significant costs to
address the problem, farmers can actually add to their bottom lines. It is
another important step in the process of realizing our mission to produce
renewable energy from animal wastes while helping control water and air
pollution stemming from animal feeding operations and addressing the nation's
need for renewable green power that is both reliable and cost efficient."

Environmental Power's anaerobic digestion systems will help animal feeding
operations meet Environmental Protection Agency and U.S. Department of
Agriculture pollution standards. These agencies have identified animal feeding
operations as the greatest contributors to the problem of excess mineral
pollutants in water runoff, the most significant remaining source of water
pollution.

In addition to required anti-pollution measures, many states are requiring that
a certain percentage of total power sold come from renewable sources. In
Wisconsin, for example, regulated utilities are required to have 2.2 percent of
total power generated come from renewable resources by 2012. Among states with
similar requirements are Arizona, Nevada, New York and Texas. Other states, such
as California, offer considerable financial incentives in support of renewable
energy.

Environmental Power is targeting its proposed anaerobic digestions systems to
animal feeding operations in the U.S. and estimates market potential for this
type of pollution control to exceed $14 billion.

this press release such as statements concerning our systems providing a
profit-generating solution and being expected to be operational by August 2003,
production of power at generating facilities to be constructed, additional farms
signing on in the near future, the beginning of the engineering and construction
phases of our projects, helping animal feeding operations meet pollution
standards, the estimated market potential for this type of pollution control our
expectation and other statements contained herein regarding matters that are not
historical facts are forward looking statements as such term is defined in the
Act. Because such statements involve risks and uncertainties, actual results may
differ materially from those expressed or implied by such forward-looking
