Active Power Helps Support Metro Hospital in Achieving LEED Certification.

"Green" UPS System Reduces CO2 Emissions; Provides Power Protection to Hospital Data Center

AUSTIN, Texas -- As energy prices continue to rapidly increase and momentum builds for tougher environmental legislation, data center operators are continually exploring ways to minimize overhead power consumption and improve energy efficiency. More and more operators are designing and building facilities to earn the U.S. Green Building Council LEED (Leadership in Energy and Environmental Design) certification or earn an ENERGY STAR, a joint program of the EPA (Environmental Protection Agency) and Department of Energy.

Grand Rapids, Mich. based Metro Health Hospital is currently seeking its LEED certification and is already earning points toward recognition with the installation of two Active Power CleanSource[R] 300E uninterruptible power supply (UPS) systems. Active Power, Inc. (NASDAQ:ACPW), inventor and manufacturer of the most energy-efficient critical power systems in the world, provides power conditioning and backup power for the hospital's data center. The data center will support Metro Health Village, which will include Metro Hospital's 480,000 square foot facility, physician offices, specialty centers, medical suppliers and retailers. Metro Health Village is scheduled to open in the fall of 2007.

"We're striving to become one of the few LEED certified hospitals in the United States and Active Power is helping us earn this accreditation," said Robert Van Rees, director, Facility and Support Services at Metro Hospital. "Active Power's flywheel based UPS systems provide exceptional levels of energy efficiency, which reduce CO2 emissions and impact our bottom line. We were also looking for a UPS system that could provide reliable back up power in the instance of a power sag, fluctuation or outage and Active Power delivers that."

CleanSource UPS is a highly reliable source of energy, delivering consistent, predictable performance over its 20-year life span with absolutely no degradation in service. With more than 35 million hours of runtime in the field, CleanSource performs at efficiency levels of up to 98 percent, which reduces energy consumption as compared to 90 percent energy efficiency with a conventional, battery based UPS system. In addition to its operational efficiency, CleanSource is easier and less costly to retrofit and install due to its smaller footprint requirements and wide operating ambient temperature range.

"Metro Hospital's move to purchase Active Power's CleanSource UPS will earn it points as it strives for LEED certification," said Jim Clishem, president and CEO of Active Power. "We're excited to be able to help maintain Metro Hospital's green record, decrease its energy bills and reduce its environmental impact."
