Do you support using electric school buses and other fleets to help power your local grid?
Between 2024 and 2026, an Oakland school bus fleet successfully acted as a backup power source for 1,000 local homes. The 74-bus electric fleet returned 1.7 gigawatt-hours of energy to the power grid while maintaining a 99.5% operational uptime.
Why it matters
This project utilizes energy arbitrage to stabilize the regional grid during high-demand periods by selling stored power back to utilities. By creating revenue from idle school buses, the program offers a new model for managing energy costs and infrastructure stability at the municipal level.
The Oakland fleet operates with 74 electric school buses featuring a total storage capacity of 11.5 megawatt-hours. Each charger delivers up to 480 kilowatts, enabling the system to support 1,000 homes during peak demand periods.
The players
Zum
An operator of electric school bus fleets and charging infrastructure technology.
Tellus Power
A provider of specialized electrical vehicle charging hardware and infrastructure.
The details
The project relies on vehicle-to-grid (V2G) technology installed by Tellus Power and Zum. These chargers allow the buses to draw power from the grid when electricity prices are low and discharge that stored energy back into the network when prices spike. This mechanism helps prevent outages and optimizes grid performance.
Timeline
2024-2026: The electric school bus fleet returned 1.7 gigawatt-hours of energy to the power grid.
The Home Front
This project reflects a broader trend of integrating electric vehicle batteries into municipal infrastructure to serve as decentralized grid storage. It signals a move toward using large-scale commercial EV fleets as a tool for community energy resilience.
Residents should note that electric fleets in their area may increasingly support grid stability during extreme weather or high-demand events. This shift highlights how modern fleet electrification is moving beyond school transportation to become a functional part of the local power infrastructure.
The takeaway
Large-scale battery storage integrated into public transit can effectively balance grid loads during peak usage. Homeowners can track local grid management developments to see how fleet electrification impacts utility infrastructure and reliability in their region.
