Hybrid Trucks 
Ameren Missouri was one of the first utilities in the nation to place a hybrid truck into service and currently operates six of these throughout our service territory.
  • The 45-foot bucket trucks are built on a 33,000 lb. gross vehicle weight rated chassis, equipped with an Eaton hybrid system.
  • The Eaton system assists the diesel engine allowing the truck to operate on 30 to 40% less fuel than a conventional truck.
  • The aerial device on these trucks can be powered by the batteries and electric motor as opposed to idling the diesel engine of a conventional bucket truck.
  • The lithium batteries are recharged during braking and whenever the diesel engine is running.
Ameren Missouri placed 13 37-foot bucket trucks equipped with Altec's new JEMS (Jobsite Energy Management System) hybrid system into service.
  • The hybrid system on these trucks is only utilized to power the aerial's hydraulic system and is not used to propel the vehicle.
  • A series of batteries and other components are housed in the rear bumper area of a standard truck chassis.
  • The hybrid batteries are recharged by plugging the truck into a standard 110-volt outlet and replenished from the vehicle's alternator when the truck is driven.
  • Using the hybrid batteries to power the aerial device eliminates the need to keep the truck's diesel engine running at the jobsite, which reduces fuel consumption and exhaust emissions.
