LTi REEnergy Selects Maxwell Technologies BOOSTCAP(R) Ultracapacitors for Backup Power in Wind Turbine Blade Pitch Control Systems

September 11, 2008

SAN DIEGO, Sept. 11 /PRNewswire-FirstCall/ — Maxwell Technologies Inc. announced today that LTi REEnergy GmbH (LTi), one of the world’s leading producers of electro-mechanical wind turbine blade pitch control systems, has selected Maxwell’s BOOSTCAP(R) ultracapacitors to supply backup power for LTi’s PitchMaster(R) blade pitch control system.

Blade pitch control systems enhance the consistency of wind turbines’ electrical energy output and ensure that rotor speed remains within a safe operating range by constantly adjusting turbine blades to compensate for changes in wind velocity. Ultracapacitors supply backup power for orderly system shutdown in the event of a main system power failure.

David Schramm, Maxwell’s president and chief executive officer, said that LTi’s PitchMaster(R) system incorporates multi-cell BOOSTCAP ultracapacitor modules based on Maxwell’s BCAP0350 “D cell” product.

“LTi supplies blade pitch control systems to a number of major wind turbine manufacturers around the world, and already sold more than one thousand PitchMaster(R) systems, so this new supply agreement represents a significant expansion of Maxwell’s penetration of the rapidly growing wind energy industry,” Schramm said. “We are pleased to be aligned with another leading player in the dynamic renewable energy marketplace.”

Matthias Vehring, LTi’s Managing Director, said that ultracapacitors were chosen over batteries for backup power because of their longer operating life, lower maintenance requirements and ability to operate more reliably in harsh climates.

“Wind turbine operators need systems that perform reliably for many years in all weather conditions with minimal maintenance,” Vehring said. “BOOSTCAP products have demonstrated their durability and reliability at temperatures ranging from -40 to +65C, which enables our pitch control systems to better meet our customers’ expectations.”

Industry sources report that nearly 20,000 MW of new wind generator capacity was installed in 2007, bringing the total worldwide installed base to approximately 94,000 MW. From 2003 through 2007, the industry maintained an annual growth rate of more than 20 percent, and it is projected to continue to meet or exceed that rate through 2012.
