The firm has raised a total of more than $180 million in VC funding from investors including Hennessey Capital, NMT Capital, Mitsui & Co. Global Investment, 88 Green Ventures, Vision Ridge Partners, Edison Energy and Constellation Technology Ventures, the VC arm of Exelon. Because buses drive fixed routes at moderate speeds and most bus routes are less than 30 miles long, they're an ideal application for electric vehicles. The relatively predictable short distances traveled allows Proterra to minimize the size of the battery pack, so the vehicles use battery packs in the 54-kilowatt-hour to 72-kilowatt-hour range. As a point of reference, the Tesla Model S has an 85 kilowatt-hour pack.
