46 Procurement and Deployment The primary drivers for deploying BEBs were generally split into two groups. Half of the transit agencies reported they implemented BEBs due to a combination of board direction, environmental regulations, and environmental/sustainability programs, while a third of the transit agencies were doing it to test the buses in their service.

50 Battery electric Buses -- State of the practice Layover Location Characteristics The responding transit agencies located on-route charging infrastructure at transit centers in seven instances, that is, at an agency-owned property in four instances and on the side of a public street in three instances. Most transit agencies have 200 square feet or more of available footprint for the charging infrastructure and light-to-no traffic density at the location they selected, as shown in Figures 25 and 26.

Survey results and planning 53 Some examples follow from transit agencies that did plan in advance for accommodating scale up: • "Analyzing a 24 year roadmap and producing model simulations." • "Collaborating with the city to ensure that it will provide more service for increased demand." • "Doing as much underground work as possible when the trenches were open." • "Planning future routes and locations based on maximum scalability." • "Locating chargers to serve existing and planned routes." • "Development of a bus maintenance facility to accommodate fleet expansion."
