/ Charlotte Douglas International Airport has started using electric shuttle buses, now CATS will test electric buses in 2022. The Charlotte City Council gave the Charlotte Area Transit System the green light to buy 18 electric buses and equipment. CATS will launch a 12- to 18-month pilot program with help from the Duke Energy subsidiary eTransEnergy, it said in a news release. Part of the testing will be to see how long the buses stay charged; there will also be workforce training. “We are excited to have developed a blueprint for public-private partnership with CATS to first pilot, then move to full-scale transit fleet electrification,” said Greg Fields, vice president of eTransEnergy.
