Overview

• The site is fully operational with 14 buses—four Thomas Built and ten Blue Bird models—and 22 chargers, including six high-power bidirectional V2G DC fast chargers and 14 lower-power units.
• PG&E completed site upgrades under Rules 15/16 and Rule 21 by installing a 480-volt three-phase service entrance, a 750 kVA transformer and a 2,500-amp switchgear to enable energy exports.
• The Mobility House’s ChargePilot platform manages charging and discharging through OpenADR signals, enabling FUSD to dispatch stored power during PG&E’s Emergency Load Reduction Program.
• The deployment forms part of the California Energy Commission’s Replicable Vehicle-to-X Deployment Study and marks FUSD as the second district in PG&E’s commercial V2X pilot, with plans to add two high-power unidirectional chargers and two more electric buses in 2026.
• By replacing six diesel buses, the program advances local decarbonization and resilience while offering a model for scaling grid-integrated school transportation statewide.
