DesignLine, Capstone to Fulfill Hybrid-Electric Bus Order for Denver Transit Fleet


DesignLine has ordered 34 C30 microturbines from Capstone Turbine Corp. to integrate into Eco Saver IV range-extended electric buses for the Denver Regional Transportation District (RTD).

These DesignLine buses have an all-electric drivetrain that uses lithium ion batteries for energy storage. The batteries are recharged by the Capstone 30 kW microturbine, which runs on diesel or biodiesel, as well as through regenerative braking technology.

The new buses, which will operate on the 16th Street Mall in downtown Denver, are replacing 36 TransTeq mall buses that have been in service since 1999 and are now being retired. Two Capstone-equipped DesignLine buses have been in service for over a year.
