The new units are anticipated to deliver fuel efficiency over a conventional truck of up to 50% annually, depending upon the use of the truck.

Odyne’s hybrid technology combines electric power conversion, power control and energy storage technology with Remy electric propulsion motors, modular Johnson Controls lithium-ion battery systems and other automotive-quality components. The Odyne plug-in hybrid drive system reduces fleet operating and maintenance costs, and depending on duty cycle, enables large trucks to obtain significant fuel economy improvements compared to traditional diesel engines.

The following have received advanced Odyne hybrid systems under the Wisconsin Clean Transportation Program:

• Milwaukee County took delivery of four work trucks in December 2011 and January 2012 that will be used throughout Milwaukee County to maintain traffic signals and street lighting. Although the county automotive fleet includes hybrids, these are the first hybrid trucks they are putting to work. Manufactured by DUECO, Inc. the vehicles feature the first Odyne hybrid systems installed on Kenworth truck chassis and are the first to power Venturo corner mount cranes, which will be used in sign maintenance and to lift lighting as the county switches to more efficient LED lighting. The trucks feature fiberglass bodies and Terex TL60 aerial buckets, recognized for their stability.

• Marshfield Utilities, serving the city of Marshfield, Wisconsin took delivery of its first Odyne hybrid truck in 2009. A second truck with a more advanced Odyne plug-in hybrid system was delivered in December 2011. Both units feature a Navistar chassis, Terex HRX55 booms and fiberglass bodies. The trucks are used for construction and maintenance of the Marshfield utility grid.

• The Richland Center unit of Wisconsin Public Power, Inc. will be putting a new Terex TCX60 boom and fiberglass body on a Navistar chassis with the Odyne hybrid system into action in their community for the construction and maintenance of the utility grid.

• The Lake Mills Unit of Wisconsin Public Power, Inc. is also putting a new Terex TCX60 with a fiberglass body on a Navistar chassis to work constructing and maintaining the utility grid.

ComEd. Separately, Commonwealth Edison Company (ComEd), one of the largest utilities in the United States, has taken delivery of the first digger derrick featuring an advanced Odyne plug-in hybrid propulsion system. The plug-in hybrid system uses energy from its battery pack to improve efficiency and power during driving, operate quietly in an all-electric mode at the job site, and is recharged using cleaner domestically produced electricity from the grid.

The Terex Commander 4042 digger derrick features a DUECO, Inc. flatbed on an IH 4300 chassis and will be used to maintain the electrical grid within the City of Chicago.

The hybrid digger derrick was funded in part by a $4-million award ComEd received in federal economic stimulus funding to expand its alternative-fuel fleet. ComEd received a $1.5 million grant from the City of Chicago that stems from $15 million in American Recovery and Reinvestment Act (ARRA) funding awarded to the city by the US Department of Energy (DOE) under its Clean Cities Grant program.
