               PLUG POWER ANNOUNCES MOUS, ADDITIONAL INVESTMENTS

Latham, N.Y. - Plug Power, Inc. (NASDAQ: PLUG), announced today that it has
entered into a non-binding Memorandum of Understanding (MOU) with GE Fuel Cell
Systems, L.L.C. (GEFCS), GE MicroGen, Inc. (GEMG), and GEPS Equities Inc., and a
separate non-binding MOU with DTE Energy Technologies, Inc., a subsidiary of DTE
Energy (NYSE: DTE).  These MOUs define new, expanded distribution agreements for
Plug Power's Proton Exchange Membrane (PEM) fuel cell systems for stationary
power applications and confirm new cash equity investments in Plug Power. The
changes proposed in the MOUs are subject to negotiation and completion of
definitive agreements to our current distribution agreements with GEFCS and DTE
Energy Technologies, Inc.


The MOU between Plug Power and certain GE entities includes provisions to:

 .    Expand GEFCS's exclusive, global (outside of a 4-state territory served by
     DTE Energy Technologies, Inc.) distribution rights to include PEM fuel
     cell-powered generators manufactured by Plug Power, of any electric power
     output, including greater than 35 kW, for use in any stationary power
     applications, including uninterruptible power supply and telecommunications
     applications.

 .    Increase Plug Power's ownership in GEFCS to 40 percent, from 25 percent
     currently. GE MicroGen's ownership interest in GEFCS will be reduced from
     75 percent to 60 percent.

 .    Grant GEPS Equities $5 million of shares in Plug Power common stock. In
     addition, GEPS Equities has made a binding commitment to purchase, for $5
     million in cash, additional shares of Plug Power common stock, at a price
     equal to the offering price in Plug Power's public offering of common
     stock, currently in registration. GEPS Equities currently owns 5.25 million
     shares in Plug Power, which represents an 11.8 percent ownership stake.

A separate, but parallel, MOU between Plug Power and DTE Energy Technologies was
executed expanding DTE Energy Technologies' exclusive distribution rights to
include


Plug Power-manufactured PEM fuel cell-powered generators of any size
output for use in any power application, except for propulsion, within the
states of Michigan, Illinois, Ohio and Indiana.

Separately, Edison Development Corporation, another DTE Energy subsidiary, has
agreed to purchase, for $5 million in cash, additional shares of Plug Power
common stock at a price equal to the offering price in Plug Power's public
offering of common stock, currently in registration.

"We are very pleased with the strengthening of the relationships with our
distribution partners, GEFCS and DTE Energy Technologies," said Roger Saillant,
CEO of Plug Power.  "We believe that the broad nature of these MOUs provides the
framework required to deliver the strategy as outlined to our Board of Directors
and shareholders back in April."

"GEFCS is pleased to have reached this level of agreement on the range of issues
covered by the MOU," said Barry Glickman, President of GEFCS.  "GEFCS looks
forward to working with Plug Power to evaluate the customer requirements for the
additional product sizes and applications contemplated by the MOU."

"DTE Energy believes that Plug Power fuel cells greater than 35 kW will be a
significant factor in helping energy companies like DTE Energy meet growth and
reliability requirements at a lower cost than alternatives" said Anthony F.
Earley Jr., Chairman and Chief Executive Officer of DTE Energy.

Plug Power designs and develops on-site electric power generation systems
utilizing proton exchange membrane fuel cells for stationary applications.  The
Latham, N.Y.-based company was founded in 1997, as a joint venture of DTE Energy
Company and Mechanical Technology Incorporated. Plug Power Holland was founded
in February 2000 as the first European operation base of Plug Power.
