TYNGSBORO, Mass.--([ BUSINESS WIRE ])--Beacon Power Corporation (Nasdaq: BCON), a company that designs and develops advanced products and services to support more stable, reliable and efficient electricity grid operation, announced that Judith F. Judson has been promoted to Vice President of Asset Management and Market Development and been made an officer of the Company. Ms. Judson had previously served as Beacona�s Director of Regulatory and Market Affairs.

"There is still more exciting work to be done"

aWea�re very pleased to recognize Judith for her numerous and noteworthy achievements in overcoming regulatory barriers and enabling Beacona�s flywheel energy storage resources to gain much broader access to electricity markets,a said Bill Capp, Beacon President and CEO. aHer knowledge of the regulatory process and her ability to collaborate so effectively with various stakeholder groups has produced tremendous progress in market rule development in a relatively short time.a

Among the notable accomplishments in which Ms. Judson played a key role is the creation of tariffs within several deregulated electricity markets that now allow non-generation resources like Beacona�s flywheels to participate. She continues to lead the effort to actively engage in each grid operating regiona�s stakeholder process and help shape language in market rules that ultimately obtain approval from the Federal Energy Regulatory Commission. As a result of these efforts, Beacon Power is now able to enter the regulation services markets in New York and the Midwest on a fair and equitable basis, and is earning ongoing revenue in the countrya�s only apay-for-performancea regulation market in ISO New England. Excellent progress is also being made in the PJM Interconnection, which appears to be nearing its own decision on favorable market rule changes for storage-based regulation service providers.

Ms. Judsona�s new responsibilities in asset management will be to manage a team that will develop Beacona�s merchant frequency regulation plants in the United States. As such, she will oversee site selection, plant development and interconnection, and be responsible for project management functions, budgets and schedules. Once each plant is built, Ms. Judson will oversee operations and direct the regulation services bidding process so as to maximize Beacona�s revenue and profit potential. On the market development side, she and her team will continue their recent work within the regulatory and stakeholder process to implement pay-for-performance-based compensation commensurate with Beacona�s high-performance, fast-response technology.

aThere is still more exciting work to be done,a Bill Capp continued, aand this new position brings with it a set of responsibilities that reflect those challenges and opportunities. I am confident that Judith will tackle her new role with the same intense commitment and results-oriented approach shea�s already shown, leveraging her proven talents and experience to help us meet our goals.a

Before joining the Company in January 2008, Ms. Judson worked for the Commonwealth of Massachusetts from 2003 through early 2007, where she rose to become the statea�s head energy and telecom regulator. As Chairwoman of the Massachusetts Department of Telecommunications and Energy, Ms. Judson managed a 150-person team to regulate the statea�s $11-billion energy industry and $4-billion telecom industry, including setting utility rates and approving new energy facilities. In addition, she served as Chairwoman of the statea�s Energy Facilities Siting Board, overseeing the siting of new energy transmission, distribution and generation assets. Ms. Judson holds an MBA from Harvard Business School and a bachelora�s degree in Mechanical Engineering from Kettering University.
