Denver Transportation District Orders Additional UQM Controllers for Hybrid Shuttles.

ENERGY RESOURCE-1 May 2007-Denver Transportation District Orders Additional UQM Controllers for Hybrid Shuttles(C)2007 JeraOne -

UQM Technologies Inc., a developer of alternative energy technologies, has received an order from the Denver Regional Transportation District for its generators and motor controllers to retrofit an additional 18 hybrid electric mall shuttle buses.

The order represents the balance of the equipment necessary to complete the retrofitting of RTD's entire hybrid electric mall shuttle bus fleet.

Each 45-foot hybrid electric mall shuttle bus will be retrofitted with a 35 kW UQM generator and two UQM power electronic motor controllers to control the operation of the electric propulsion motors currently installed in each bus.

Denver RTD introduced its hybrid electric fleet of MallRide shuttles in 2000, the first large-scale deployment of hybrid electric buses for transit use in the United States. A total of 36 MallRide shuttles operate on the 16th Street Mall in downtown Denver providing a free ride for passengers across the 1.3-mile long 16th Street Mall, which connects with the light rail, express and regional Denver RTD services offered at Denver Union Station, Market Street Station and Civic Center Station.

The hybrid electric MallRide shuttle buses are powered by a compressed natural gas-fueled 2.5 liter Ford industrial engine that operates at 2,200 r.p.m. and will turn the UQM generator to produce electricity to recharge the bank of batteries that power the shuttle.
