18 <strong>Chatsworth, Calif. &ndash; April 30, 2008</strong> &ndash; Pentadyne Power Corporation, the world's leading manufacturer of clean energy storage systems using advanced composite flywheel technology, announced today that it has shipped its 500th flywheel energy storage system. <br /> <br /> In addition, the company announced that the installed fleet of Pentadyne flywheel energy storage systems &ndash; primarily used with large-scale uninterruptible power supply (UPS) systems instead of lead-acid batteries&nbsp;&ndash; has amassed a total of two million hours of operation. The company&rsquo;s first commercial installation, at the NASA Glenn Research Center in Cincinnati, has amassed more than 35,000 hours of operation since commissioning in March 2004. <br /> <br /> Pentadyne President &amp; CEO Mark McGough said, &ldquo;These two significant milestones occurring within a few days of each other underscores the rapid and growing acceptance of our product in the marketplace. UPS users are looking for the most energy efficient reliable alternative to lead-acid batteries, and they are clearly finding it in our product. Considering that we&rsquo;ve shipped nearly 90% of those 500 units in the last 24 months, the growth rate is astounding.&rdquo; <br /> <br /> <a target="_blank" href="http://www.fiber.net">Fibernet</a>, a colocation center based in Orem, Utah, took delivery this week of Pentadyne&rsquo;s 500th flywheel system, which they purchased through the world&rsquo;s leading large-scale UPS manufacturer, <a target="_blank" href="http://www.liebert.com">Emerson Network Power/Liebert</a>. <br /> <br /> &ldquo;The 500th Pentadyne-made flywheel is the second one purchased by Fibernet, and will be used with a 150-kVA Liebert UPS,&rdquo; said Pentadyne Vice-President of Sales &amp; Service Johnny Gonzales. &ldquo;Their first Pentadyne-made Liebert FS flywheel, which they purchased 12 months ago, has been operating flawlessly with a 225-kVA Liebert UPS at Fibernet&rsquo;s state-of-the-art Class A &lsquo;smart building.&rsquo;&quot; <br /> <br /> According to Fibernet CFO J. Lee Livingston, &ldquo;We were skeptical about flywheels. But the ability to rid ourselves of the hazards, maintenance and poor reliability of lead-acid batteries, coupled with the reliability and lower operating costs of the flywheel were convincing. We now have a year&rsquo;s worth of battery-free and fault-free operation under our belt. So when our growth demanded expansion of our power protection capabilities, it was an easy decision to address that with another flywheel-based UPS.&rdquo; <br /> <br /> <strong>About Pentadyne Power Corporation</strong> <br /> Hundreds of award-winning Pentadyne clean energy storage systems are deployed as a part of battery-free UPS solutions at commercial, industrial, hospital and military facilities worldwide.
