Foothill Transit Battery Electric Bus Demonstration Results: Second Report

This report summarizes results of a battery electric bus (BEB) evaluation at Foothill Transit, located in the San Gabriel and Pomona Valley region of Los Angeles County, California. Foothill Transit began a demonstration of three Proterra BEBs in October 2010 to evaluate the battery technology and determine if the BEBs could meet Foothill Transit’s service requirements. The initial demonstration went well and in 2014, Foothill Transit moved forward with an order of twelve next-generation BEBs from Proterra through a $10.2 million grant under the Federal Transit Administration’s (FTA’s) Transit Investments for Greenhouse Gas and Energy Reduction (TIGGER) Program. Foothill Transit’s project goal was to fully electrify one route in its service area—Line 291—and to investigate the feasibility of the technology for other routes. The focus of this evaluation is to compare the performance and the operating costs of the BEBs to that of the baseline conventional technology buses and to track progress over time. In the commercialization process described by technology readiness levels (TRLs) 1 through 9—from basic research/concept to commercial deployment—National Renewable Energy Laboratory (NREL) considers the BEBs to be at TRL 7. The primary goals of the in-service demonstration are to verify that technical performance targets are met and to identify any issues that need to be resolved. This is the second report summarizing the results of the BEB demonstration at Foothill Transit. The first report covered the initial data period of April 2014 through July 2015. This report provides data and analysis on the twelve Proterra BEBs and eight NABI compressed natural gas (CNG) baseline buses from August 2015 through December 2016.
