Description

The Oakland Unified School District, in collaboration with Zum and utility provider PG&E, has achieved a groundbreaking milestone by transitioning to a 100% electric school bus system with vehicle-to-grid (V2G) technology. This initiative, the first of its kind in the US, involves a fleet of 74 electric buses equipped with bidirectional chargers managed through Zum's AI-enabled platform. By becoming emissions-free and serving as a Virtual Power Plant (VPP), this fleet not only addresses environmental concerns but also contributes 2.1 gigawatt hours (GWh) of energy back to the grid annually. This transformative project not only benefits the Oakland community but also sets a precedent for other districts, with plans to electrify school bus fleets in San Francisco and Los Angeles next.
