             ACTIVE POWER PROMOTES JIM CLISHEM TO PRESIDENT AND COO

Austin, Texas (November 8, 2005) -- Active Power, Inc. (NASDAQ: ACPW) today
announced that Jim Clishem, its Vice President of Marketing and Business
Development, has been named the Company's President and Chief Operating Officer.

Mr. Clishem joined Active Power five months ago, bringing extensive expertise in
the computer, telecommunications and managed IT services industries. Clishem
came to the Company from Peregrine Systems, Inc., a publicly traded enterprise
software company, where he served as Vice President of Business Development
focusing on global alliances since 2004. From 1999 until it was sold in 2004, he
was founder-CEO of Xodiax, a profitable managed IT services business, which was
recognized by Inc Magazine as one of the fastest growing privately held
companies in the country. Clishem also served as Vice President of Data Services
for Broadwing Communications, where he had P&L responsibility for a $150 million
business unit. He has also held various senior roles at MCI, Ericsson, and
Tandem Computers.

"With the launch of our new CoolAir(TM) DC product line next week, Active Power
is significantly expanding its sales and marketing efforts to support this new
business and Jim brings a wealth of experience in these areas," said Joe
Pinkerton, Chairman and CEO of Active Power. "Jim has led sales and marketing
organizations, run profitable businesses and transformed a startup into a
profitable entity in under two years. He is intimately familiar with the backup
power needs of data center and telecom customers, having been a customer of this
equipment during his tenure at several successful telecom and managed IT
services businesses."

"I'm extremely excited about the opportunity that Joe and the Board of Directors
have given me," said Clishem. "I'm eager to begin taking a more prominent role
in the day-to-day operations of Active Power and in the strategic direction of
the business. My first priorities are to successfully manage the commercial
launch of CoolAir DC, drive revenue growth across all product lines and
accelerate the Company toward profitability."

Mr. Clishem will continue to report to Pinkerton, who remains the Company's
Chairman and Chief Executive Officer.
