Chatsworth, Calif. – Nov. 29, 2007 – Pentadyne Power Corporation, the world’s leading manufacturer of clean energy storage systems using advanced composite flywheel technology, announced today that it has received an order for 24 Pentadyne-made flywheels to be deployed at a major technology research and development center in Omaha, Nebraska.

The two dozen Liebert FS systems from Emerson Network Power, which can provide more than 4.5 megawatts of backup power, will be paralleled with six, 750-kVA Liebert 610 UPS systems. Emerson Network Power is one of the world’s leading manufacturers of 3-phase uninterruptible power supply (UPS) systems. It markets the Pentadyne flywheel as the Liebert FS.

“With 24 Liebert FS units, this will be the one site that has the most Pentadyne-made flywheels operating together,” said Pentadyne President & CEO Mark McGough.

Flywheel energy storage systems are used as a supplement to increase the reliability of conventional UPS lead-acid battery banks, or to entirely eliminate them and their associated recurring costs, frequent maintenance issues, poor reliability and environmental impact.

“This was yet another win where the superior product offerings of Pentadyne and Liebert beat out those of our primary competitor in the flywheel-UPS marketplace,” said Johnny Gonzales, Pentadyne’s Vice President of Sales & Service. “The customer recognized the value of our product’s vastly lower maintenance needs as well as the energy savings of our flywheel system on a double-conversion UPS versus the flywheel system of our primary competitor. In this case, that energy efficiency difference amounts to nearly 400 megawatt-hours per year. That equates to tens of thousands of dollars in annual utility bill savings and the mitigation of more than half a million pounds of carbon dioxide every year, year after year.”

Exhibiting, presenting at trade show today
The Pentadyne-made Liebert FS flywheel is on display at the national Emerson Network Power AdaptiveXchange show currently in Baltimore. Pentadyne presented on flywheel technology earlier today at the event and is scheduled to repeat the presentation tomorrow as part of the AdaptiveXchange TechUniversity series of continuing education lectures.
