AUSTIN, Texas -- Customers who manage mission critical operations are striving for improved efficiencies at a lower total cost of ownership without compromising reliability. To help address this industry issue, Active Power, Inc. (NASDAQ: ACPW), is showcasing their PowerHouse system, a containerized mission critical power infrastructure product alongside the HP Performance Optimized Data Center (POD) at the HP Technology Forum and Expo, June 15-18, in Las Vegas at the Mandalay Bay Hotel. The company is conducting tours and demos of the complete continuous power and cooling system in Bayside C at the hotel.

“This event showcases the world’s leading information technology and Active Power is excited to have the opportunity to engage with IT professionals from around the world,” said Jim Clishem, president and CEO, Active Power. “These challenging economic times require organizations to make the most of every IT dollar spent.

In addition to the equipment demonstration, Martin Olsen, vice president, Business Development for Active Power will also deliver a presentation on the economic and performance benefits of a containerized data center and power and cooling infrastructure approach.
