Tucson, Ariz.’s Sun Tran introduced its first electric bus into service on Sunday. The GILLIG electric bus is powered only by battery and produces zero-emissions, contributing to cleaner and healthier air in Tucson. Utilizing advanced technology, the electric bus provides a quieter and comfortable ride for passengers.

This is the first electric bus to be deployed in Sun Tran’s fleet, and will be leased for the next year. Sun Tran has purchased and expects to receive five additional electric buses later this year, paid for with funding awarded by the Federal Transit Administration’s (FTA) Low-No Emission Grant program.

Sun Tran and the City of Tucson recognize the advantages of incorporating an all-electric bus program, including reducing greenhouse gas emissions, lowering maintenance costs, and offering quality service to passengers.

Since 2006, 100 percent of Sun Tran’s fleet is powered by clean fuel technology. Sun Tran’s fleet currently runs on biodiesel, CNG and hybrid-electric power sources.

“Sun Tran is invested in creating an innovative and smart transportation system,” said Steve Spade, Sun Tran GM. “Our passengers can be confident they are contributing to a more sustainable community and cleaner air.”

The electric bus will be used on various routes to test its performance in the Sun Tran system and in the desert climate.

Tucson Electric Power (TEP) upgraded Sun Tran’s electrical system and installed a new bus charging system at no cost to Sun Tran.

The 40-foot electric bus has a battery capacity of 444 kWh and features a low-floor design.
