Duluth Transit Authority adds two electric buses to cleaner fleet

Two new electric buses joined the Duluth Transit Authority fleet, a small purchase that could matter most if it delivers quieter rides, cleaner air and lower operating costs on the routes people use every day.

The new 40-foot battery electric buses add to a transit system that has already made Duluth a test case for electric service in a city with steep hills and freezing winters. DTA says the buses bring lower emissions, reduced noise pollution and potential savings as fuel prices rise, benefits that will be judged not by the technology itself but by whether riders notice a smoother trip and the agency sees real value over time.

That question is especially important in St. Louis County, where DTA service reaches beyond Duluth into Superior, Wisconsin, and parts of Proctor, Hermantown and Rice Lake. For students, workers, older adults and riders who rely on the bus, fleet decisions shape how dependable the system feels at street level, not just how modern it looks on paper.

DTA has been here before. On Oct. 25, 2018, the agency introduced seven electric Proterra buses and said it was the first transit agency in Minnesota to operate electric fixed-route buses. Those buses were financed with a $6.3 million Federal Transit Administration grant plus Minnesota Department of Transportation funding, and DTA said at the time they cost about $900,000 apiece. Then-general manager Phil Pumphrey said the agency expected them to have about one-third the life-cycle cost of a diesel bus.

The long-term test has been real, not theoretical. The National Renewable Energy Laboratory and the U.S. Department of Energy evaluated DTA’s seven battery-electric buses in revenue service from December 2018 through February 2022, while a separate 2022 report documented DTA’s work with NREL and the Center for Transportation and the Environment to compare electric and conventional buses in similar service. That research matters because it tracks how the buses held up on actual Twin Ports streets, where winter cold and steep grades have challenged electric range and performance.

DTA’s own materials say its electric buses can travel up to 200 miles on a full charge and take two to five hours to charge at the operating center. The agency also notes that the buses use a diesel-fueled auxiliary heater, a reminder that in Duluth’s climate even cleaner transit still requires practical workarounds.

The addition of two more buses does not remake the fleet overnight, but it does show DTA is still betting that electric transit can be more than a symbolic pilot. If the agency can keep the buses reliable and useful in daily service, the payoff will be measured in quieter streets, fewer tailpipes and steadier operating costs for the people who pay the fares and taxes that keep the system moving.
