In Texas, 30,541 school buses were in operation during the 2018–2019 school year (2). School districts have many options when purchasing school buses. This technical memorandum reviews current use and availability of electric school buses on the market and provides valuable information that can assist school districts in making purchasing decisions. The Texas Department of Transportation (TxDOT) tasked the Texas A&M Transportation Institute (TTI) with conducting this literature review and industry scan of electric school buses to proactively assist school districts in their efforts toward researching and/or implementing electric school bus use.
