Active Power announced that Oregon Health and Science University (OHSU) has deployed an additional two megawatts of Active Power CleanSource® UPS (uninterruptible power supply) systems at its campus in Portland, Oregon. These new flywheel UPS systems protect operating rooms and imaging equipment at Doernbecher Children's Hospital from downtime due to electrical interruption. The equipment has performed flawlessly since startup six months ago during second phase build out of the facility's electrical room which was recently completed. When selecting a UPS system, OHSU debated between flywheel technology as well as conventional battery and rotary based solutions. The health care organization ultimately chose to deploy Active Power's integrated flywheel UPS due to its superior reliability and battery-free design, resulting in lower costs over the life of the system. The solution also aligned with the hospital's environmental sustainability program.
