First National Side-By-Side Study of Hybrid
School Buses Launched Contact: December 3, 2008 FOR IMMEDIATE RELEASE SCHENECTADY— New York Power Authority (NYPA) President and Chief Executive Officer Richard M. Kessel and New York State Energy Research and Development Authority (NYSERDA) Vice President for Programs Robert Callender today were joined by Schenectady City School District Superintendent Eric Ely to launch the first national side-by-side study of the performance of different hybrid school bus technologies. These buses are expected to operate more cleanly and efficiently than traditional school buses, reduce greenhouse gas emissions and improve air quality. The NYPA Hybrid School Bus Study is a three-year demonstration and evaluation program using two types of diesel-electric hybrid buses—a standard hybrid and a plug-in hybrid—traveling under the same conditions and routes as a conventional diesel school bus in urban, suburban and rural areas of New York State. Schenectady Central School District is the first of three school districts to participate in the study. The goal of the evaluation is to compare the two hybrid buses and a conventional diesel school bus for fuel and energy efficiency, emissions reductions, reliability and maintenance costs. The study will examine how differences in bus routes, such as average speed, number of stops, idle time, hilly or flat roadways, affect performance. The study cost, including hybrid bus purchases, a conventional bus lease and the evaluation report, totals about $664,000. Funding is being provided by NYPA with $297,000 and NYSERDA is committing $210,000. As a member of the Hybrid School Bus Buyers’ Consortium, NYPA also received $157,000 towards the hybrid buses from the National Association of State Energy Officials State Technologies Advancement Collaborative. This Consortium, facilitated by Advanced Energy, a non-profit organization based in North Carolina, consists of members from state agencies, school districts and utilities from 11 states around the country. NYPA purchased the two hybrid school buses from Leonard Bus Sales, Deposit, N.Y., which is also providing three years of service and technical support. The buses were built by IC Bus, an affiliate of Navistar International, and are equipped with hybrid propulsion systems manufactured by Enova Systems, Inc. of Torrance, Calif. Brown Transportation will take title to the two hybrid buses and the conventional “baseline” diesel bus and will operate the buses for the first year of the study. The hybrid buses will be rotated with the conventional school bus on the same three routes throughout the year so that the performance of the buses can be compared. A contract for the evaluation was awarded to M.J. Bradley & Associates LLC for $186,000. During the first year of the three-year in-service test, data will be collected from the buses as they are operated in regular service on a select group of Schenectady school bus routes which are designated as suburban. Similar test periods for urban and rural routes will be developed once the other locations are determined. The study report is estimated to be completed in 2012. Shenendehowa Central School District has also agreed to participate in the first year of this study and will provide data from operating its own plug-in hybrid bus on rotation with a conventional diesel school bus on the same routes within its district. This data will help broaden the study results. For the study, NYPA and NYSERDA put together a project team to serve as the advisory committee through all phases of this project. The Project Team includes NYPA, NYSERDA, Schenectady Central School District, Brown Transportation, Shenendehowa Central School District, Leonard Bus Sales, IC Bus, Advanced Energy, New York School Bus Contractors Association, New York Association for Pupil Transportation, New York State Department of Education, NYS Dept. of Environmental Conservation and NYS Dept. of Transportation. Since the early 1990s, NYPA has put into service over 1,000 electric and hybrid-electric vehicles in its own fleet and the fleets of its customers throughout New York State. Those vehicles have traveled over 10 million miles displacing an estimated 35,000 barrels of oil and avoiding over four tons of CO2. In 2000, the Electric Drive Transportation Association, the preeminent industry group dedicated to advancing electric drive, recognized NYPA as the first utility in the Northeast to pass the million-mile mark for combined electric vehicle mileage. MORE FACTS ABOUT NYPA HYBRID BUS DEMONSTRATION PROGRAM All three buses will be the same base model with the same diesel engines, with the conventional bus serving as the “baseline” bus for the study. The hybrid buses represent two different types of hybrid technology. There is a standard hybrid bus which combines a storage battery and electric motor with the diesel engine. There is also a plug-in hybrid which has a larger storage battery than the standard hybrid, an electric motor, an on-board charger and a wall plug connection. The hybrid buses operate with their engines running at a more constant level than conventional buses, with additional power supplied by the storage batteries when accelerating. The battery on the standard hybrid gets its power from the regenerative braking system. During braking the electric motor acts as a generator, producing electricity that goes to the battery and is stored for use during acceleration. The battery on the plug-in gets its power from the both its regenerative braking system and the electric grid. This battery, which is larger, supplies power to the electric motor during acceleration and also provides supplemental power to the diesel engine at other times, so the energy stored in the battery gradually depletes over the course of the day. The battery is re-charged overnight when the bus is plugged into an electric outlet. Fuel/energy use and maintenance data will be collected by the bus operators on a monthly basis. All buses used for this evaluation will be equipped with the Navistar Aware system that will collect data such as miles traveled and fuel consumed. Other data collection methods will also be used including manual records of maintenance reports and downloads from the hybrid buses’ energy management systems.
