NEW YORK -- A new government report says New York City's newer hybrid-powered buses cost 40 percent less to maintain and 24 percent less to operate than earlier-generation hybrids. Those buses, the second-generation Orion VII from Daimler Buses North America, are powered by BAE Systems' HybriDrive® diesel-electric propulsion system
The U.S. Department of Energy's National Renewable Energy Laboratory (NREL) evaluated the performance of New York's second-generation Orion VII buses from February 2006 to January 2007. The buses studied were compared to the city's first-generation Orion VII buses. (Click here to view the report.)
"The NREL study shows that our commitment to continually improving the HybriDrive system is paying off for our customers," said Rich Hopf, vice president of vehicle systems for BAE Systems in Johnson City, New York. "We have improved reliability, simplified maintenance, and reduced the cost of keeping the buses on the road. We expect even better results with the addition of lithium-ion energy storage in 2008."
BAE Systems is offering lithium-ion energy storage on Daimler's Orion VII Next Generation transit buses. Lithium-ion technology is more efficient, lasts longer, and weighs less than the lead-acid batteries in use today. The Orion VII Next Generation buses were introduced to the North American market in 2007.
"The gains in operating and maintenance costs as referenced in the latest NREL report are a clear indication of the benefits of hybrid buses in public transit applications," said Patrick Scully, chief commercial officer for Daimler Buses North America. "These results are proof positive for not only New York City but for all of our other customers that are operating Orion hybrid buses. Further, for cities looking to adopt hybrid buses, the NREL report provides excellent empirical data for their decision-making process."
Daimler Buses and BAE Systems together are the world's leading supplier of hybrid buses, with more than 1,000 buses with hybrid propulsion systems in service in cities such as New York, Houston, Ottawa, and Toronto, and 1,500 more on order. The New York City fleet is the largest hybrid bus fleet in the world.
The buses in the study incorporated several improvements to the hybrid electric propulsion system, in use in New York since 1998. Factors contributing to the performance improvements included a simplified cooling-system design, improved battery diagnostics, and better training of mechanics.
NREL is the Department of Energy's primary lab for renewable energy and energy efficiency research and development,
