ACPW - Active Power, Inc.

Active Power, Inc. (ACPW) was a manufacturer of backup power systems and continuous power solutions that was based in Austin, Texas, United States. The company's products included flywheel-based uninterruptible power supply (UPS) systems and modular infrastructure solutions. Active Power served customers in a variety of industries including data centers, hospitals, manufacturing plants, and telecommunications facilities.

The company was founded in 1992 and went public in 2000. However, it struggled financially for many years and was acquired by Piller Power Systems, Inc. in 2016. At the time of its acquisition, Active Power had approximately 70 employees and annual revenue of around $60 million.

Active Power's flywheel-based UPS systems were designed to provide reliable and efficient backup power in the event of a power outage. Unlike traditional battery-based UPS systems, which require frequent maintenance and replacement, Active Power's flywheels offered a longer lifespan and lower total cost of ownership. The company's modular infrastructure solutions, which included integrated power and cooling systems, were designed to simplify data center construction and reduce energy costs.

Active Power's products were sold primarily in North America and Europe, and the company had a network of authorized resellers and distributors around the world. Its customers included major corporations and organizations such as Microsoft, Dell, HP, and the U.S. Department of Defense.

Overall, Active Power's focus on providing innovative and energy-efficient backup power solutions helped to differentiate it from competitors in the industry. However, the company's financial struggles and inability to achieve sustained profitability ultimately led to its acquisition by Piller Power Systems.
