Pentadyne Ships 500th Flywheel System; Installed Fleet Amasses 2M Hours

CHATSWORTH, Calif.--(Business Wire)--
Pentadyne Power Corporation (www.pentadyne.com), 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.

In addition, the company announced that the installed fleet of
Pentadyne flywheel energy storage systems -- primarily used with
large-scale uninterruptible power supply (UPS) systems instead of
lead-acid batteries -- has amassed a total of two million hours of
operation. The company'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.

Pentadyne President & CEO Mark McGough said, "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've shipped nearly 90%
of those 500 units in the last 24 months, the growth rate is
astounding."

Fibernet (www.fiber.net), a colocation center based in Orem, Utah,
took delivery this week of Pentadyne's 500th flywheel system, which
they purchased through the world's leading large-scale UPS
manufacturer, Emerson Network Power/Liebert (www.liebert.com).

"The 500th Pentadyne-made flywheel is the second one purchased by
Fibernet, and will be used with a 150-kVA Liebert UPS," said Pentadyne
Vice-President of Sales & Service Johnny Gonzales. "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's state-of-the-art Class A 'smart building.'"

According to Fibernet CFO J. Lee Livingston, "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'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."
