Siemens to Supply State-of-the-Art Energy Efficient Substations for Dallas

Siemens Transportation Systems, Inc. won a $30 million base contract this month to supply Dallas Area Rapid Transit (DART) with 24 thyristor controlled rectifier substations for DART’s latest Southeast and Northwest corridor expansions. The contract includes an option for an additional 14 substations. Substations are used to distribute power to light rail vehicles along a light rail alignment. Siemens’ latest substation technology offers better voltage stabilization for more energy efficiency, which can also reduce equipment costs. Additionally, the Siemens contract carries 17% disadvantaged business enterprise (DBE) content that has yet to be achieved in these types of contracts within the industry.

“Siemens state-of-the-art technology provides us with the means to be more energy efficient and cost effective,” stated Gary C. Thomas, president and executive director of DART. “These are the types of solutions we need to meet our long-term transportation and mobility goals.”

Siemens’ Sitras Thyristor Controlled Rectifier (TCR) units are used to supply power to DC railways. Up to a certain loading current, they are capable of keeping the supply voltage of a substation to an almost constant level. When compared to standard substations, the Siemens’ Sitras TCR substation is much more efficient by reducing voltage drop and allowing the distance between substations to be extended.

“This contract also demonstrates our commitment to businesses owned by minorities, women, and the physically disabled,” said Oliver Hauck, president and CEO of Siemens Transportation Systems, Inc.

The first substation is scheduled to be delivered by October 2008 and all 24 to be completed by 2010 and by 2011 for the added option. The DART substations are based on those that Siemens supplied to Valley Metro in Phoenix, Arizona. The Sitras TCR will be produced at a Siemens manufacturing facility in Trondheim, Norway and shipped to the U.S. for final assembly in Dallas, Texas. Additional components for the substation will be provided by various Siemens operating companies in the U.S. for a 90% or more U.S. content volume.
