                CALIFORNIA ENERGY COMMISSION AWARDS Beacon Power
             $1.2 MILLION CONTRACT FOR MAJOR ENERGY STORAGE PROJECT

     Beacon's Flywheel-based Smart Energy Matrix System Prototype Will Be
     Demonstrated in Frequency Regulation and Grid Stability Application

WILMINGTON,  Mass.  - February  14, 2005 -- Beacon  Power  Corporation  (Nasdaq:
BCON),  a company  that designs  advanced  products and services to support more
reliable  electricity  grid  operation,  today  announced that it has executed a
contract with the California Energy Commission to demonstrate an advanced energy
storage  solution for frequency  regulation  and grid  stability.  At a business
meeting on December 1, 2004,  the  California  Energy  Commission  had given its
approval to the  project,  leading to contract  negotiations  that have now been
finalized.  The  contract is expected to produce  approximately  $1.2 million of
revenue, with the majority of it in 2005.

Under  the  contract,  Beacon  Power  will  develop  and  install  a  system  to
demonstrate  the potential  benefits of using flywheel energy storage to provide
frequency  regulation of the grid, a service  required by all grid operators.  A
successful demonstration of frequency regulation with the California Independent
System Operator (ISO) will also serve to demonstrate the system's  technical and
market feasibility in a large, important,  growing market - stabilization of the
grid. The contract calls for the system to be delivered and installed during the
first half of 2005.

"Flywheel-stored  power,  which  has  long  been in use  but  not  yet for  grid
applications,  could offer the  California  ISO an  alternative to keeping power
plants on spinning reserve to balance the system," said Energy  Commissioner Art
Rosenfeld.  "When proven viable,  the technology can help save the grid operator
money on ancillary  services," added  Rosenfeld,  who is the presiding member of
the Energy Commission's RD&D Committee.

Bill Capp, Beacon Power president and CEO, said, "This agreement with the Energy
Commission  is another  opportunity  for Beacon to show how our flywheel  energy
storage solutions can provide superior frequency regulation services and improve
grid  reliability.  We are already working under contract to NYSERDA in New York
to deliver a similar demonstration system. We're convinced that our Smart Energy
Matrix  solution  would  provide  a  competitive   alternative  to  conventional
regulation  services,  and we applaud the vision and  leadership of these energy
authorities in California and New York."

Grid  operators,  such as the  California  Independent  System  Operator  (ISO),
purchase frequency  regulation services every day that are equivalent to 1-2% of
the amount of energy  used  daily.  In 2003,  the value of  regulation  services
purchased by four U.S.  regional grid  operators in open power markets  exceeded
$400 million.  The Beacon Smart Energy Matrix is being specifically  designed to
address this  sizeable and growing  market with better  performance  and greater
cost effectiveness than existing methods.

"Flywheel  technology  has the potential to provide a rapid  injection of energy
for several  minutes to help keep the grid stable when we have a contingency  --
for  example,  some kind of problem  that  causes a big power  plant to drop off
line," said  California ISO Interim Chief  Operations  Officer Jim Detmers.  "By
helping out with this  demonstration  project,  the ISO is fostering  technology
that shows real promise to improve the control and reliability of the grid."

The  demonstration  will be a  one-tenth-power  prototype  of  Beacon's  planned
megawatt-level  system  known as the Smart  Energy  Matrix.  It is  designed  to
provide grid  frequency  regulation at a site located in San Ramon,  California.
The   demonstration   will  integrate  Beacon  flywheels  and  associated  power
electronics  into the local  distribution  grid.  The project will also focus on
communication  with  and  control  of  the  demonstration-scale  system  by  the
California  ISO.  Beacon Power is teaming with Connected  Energy  Corporation of
Rochester,  New York, to develop the intelligent  monitoring and control systems
that  will  be  used  in this  California  project,  as  well as two  previously
announced in New York State.

"Through these demonstrations, we'll be able to show how advanced energy storage
solutions  like  ours can help  operators  manage a  `smarter,'  more  resilient
electricity grid," Capp continued.  "We believe that our technology will be more
responsive,  more sustainable,  and ultimately more cost-effective,  and we look
forward to a successful demonstration in two very important states in the coming
months."

                           About Frequency Regulation

One of the most  challenging  aspects  of today's  electricity  grid is that the
amount of power  generated  and the amount  consumed must be in exact balance at
all times.  When imbalances occur, the frequency of electricity (60 hertz in the
U.S.) that end users require will not be  maintained,  which  adversely  affects
grid  stability.  The  constant  balancing  of power  demand and  production  to
maintain frequency is called frequency regulation.

Beacon's Smart Energy Matrix is a  flywheel-based  energy storage system that is
intended to be a long-life,  environmentally  friendly  solution  for  frequency
regulation,  with no fuel  consumed and no emissions  generated.  The  equipment
could be  located  nearly  anywhere,  including  at a  substation  or within the
distribution  system,  where  additional  benefits  such as voltage  regulation,
backup power, or reactive power can also be provided for even greater value.

The evolution of deregulated  electricity markets has created an opportunity for
new  companies  and  technologies  to compete to  provide  frequency  regulation
services to system  operators.  Beacon Power  believes it is well  positioned to
offer a unique and sustainable  technology solution to provide this service cost
competitively, in a dynamic and growing market that has historically had limited
options.
