Acadia National Park is testing electric buses on its Island Explorer bus routes.
The 32 buses in Acadia’s Island Explorer fleet carry as many as 650,000 passengers annually. Since 1999, they’ve been powered by propane, in an effort to reduce emissions.
This month, the National Park Service is taking the first step toward electric buses, testing out models by two different manufacturers in a pilot project supported by the U.S. Department of Energy and Department of Transportation.
Acadia’s John Kelly said the early results are promising.
“We’re testing the issue of elevation changes and distance in the routes on MDI, but we’re seeing initially good results in terms of the amount of charge that’s remaining at the end of the day,” Kelly said.
Kelly said on a round-trip test drive from Bar Harbor to the summit of Cadillac Mountain, one of the buses used only about 3 percent of its battery power. He said if electric buses prove feasible in the park, they will likely be phased in over many years.
The park began testing its second bus model Monday.
