Abstract
The National Renewable Energy Laboratory has developed a technology maintenance readiness level (TMRL) guide for advanced technology vehicle fleets to help fleet operators (such as transit agencies) assess their readiness level to maintain new zero-emission buses. This guide mirrors a technology readiness level guide, but it focuses on the ability of the fleet operator to maintain and repair the advanced vehicle technology rather than defining the commercial readiness of the technology itself.
