NEW YORK, Sept. 10, 2013 /PRNewswire/ -- Pomerantz Grossman Hufford Dahlstrom & Gross LLP is investigating claims on behalf of investors of Active Power, Inc. ("Active Power" or the "Company") (NASDAQ: ACPW).  Such investors are advised to contact Robert S. Willoughby at rswilloughby@pomlaw.com or 888-476-6529, ext. 237.

The investigation concerns whether Active Power and certain of its officers and/or directors have violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934.  On April 30, 2013, Active Power announced that it had entered into a "[n]ew strategic distribution partnership agreement with Digital China Information Service Limited.  The Company represented that this relationship with Digital China would allow the Company to increase its revenues and profitability.  On September 5, 2013, after close of trading, the Company retracted its guidance, citing disappointing results in China. The Company attributed the Company's poor result to the fact that "the company's previously announced agreement in China is with Qiyuan Network System Limited, which the company's management discovered is neither an affiliate nor a subsidiary of Digital China Information Service Company Limited."

On this news, shares of Active Power fell $0.48 per share to more than 13.71% from the opening price of $3.50 on September 5, 2013 to close at $3.02 on September 6, 2013.
