WILMINGTON, Mass. -- Beacon Power Corporation (NASDAQ: BCON), a development stage company that designs, develops, and delivers sustainable energy storage and power conversion systems, has announced that it has been awarded a contract from Bechtel Bettis, Inc., to design and deliver an advanced flywheel-based power system demonstration unit.

"We're pleased to receive this contract, which reinforces an important aspect of our overall strategy," said Bill Capp, Beacon Power president and CEO. "We continue to seek and perform contract R&D that can leverage Beacon technology and complement our primary business focus, which is to design products and services for a more reliable electricity grid.

These forward-looking statements are identified by the use of terms and phrases such as "believe," "expect," "plan," "anticipate," and similar expressions identifying forward-looking statements. Investors should not rely on forward-looking statements because they are subject to a variety of risks, uncertainties, and other factors that could cause actual results to differ materially from Beacon Power Corporation's expectation. These factors include: a short operating history; a history of losses and anticipated continued losses from operations; a need to raise additional capital combined with a questionable ability to do so; conditions in target markets; no experience manufacturing any product on a commercial basis; the Company has only recently entered into the renewable energy market through its inverter products, and hence, has only limited experience in this sector; the dependence of sales on the achievement of product development and commercialization milestones; the uncertainty of the political and economic climate of any foreign countries into which Beacon hopes to sell, including the uncertainty of enforcing contracts and the potential substantial fluctuation in currency exchange rates in those countries; significant technological challenges to successfully complete product development; dependence on third-party suppliers; intense competition from companies with greater financial resources; possible government regulation that would impede the ability to market products; possible product liability claims and the negative publicity which could result; any failure to protect intellectual property; the possible need in the future to hire and retain key executives; the recent volatility in the stock price of companies operating in the same sector; the power of controlling shareholders and the limited ability of others to influence the outcome of matters put to the vote of shareholders. These factors are elaborated upon and other factors may be disclosed from time to time in Beacon Power Corporation's filings with the Securities and Exchange Commission. Beacon Power Corporation expressly does not undertake any duty to update forward-looking statements.
