NEW YORK, Sept. 11, 2013 /PRNewswire/ -- Harwood Feffer LLP (www.hfesq.com) is investigating potential claims against the board of directors of Active Power Inc. ("Active Power" or the "Company") (NASDAQ: ACPW) concerning whether the board has breached its fiduciary duties to shareholders.

In April 2013, the Company announced a purported strategic partnership with Digital China Information Service Limited ("Digital China").  On September 5, 2013, Active Power retracted its guidance for the third quarter of 2013 and stated that the strategic partnership that it had supposedly previously entered into with Digital China was actually with an entity that "is neither an affiliate nor a subsidiary" of Digital China.

Our investigation concerns whether the Company board of directors has breached its fiduciary duties to shareholders, grossly mismanaged the Company, and/or committed abuses of control in connection with the foregoing.
