74 electric school buses in California send 1.7 GWh back to the grid

Oakland's school district has run 74 electric buses with Tellus Power V2G chargers for two years: 11.5 MWh of onboard storage and up to 2 MW of discharge, enough for about 1,000 homes. The fleet has returned 1.7 GWh to the grid with over 99.5% uptime and earns money through energy arbitrage.

• 74 buses hold 11.5 MWh and discharge up to 2 MW to the grid
• 1.7 GWh returned over two years with 99.5% uptime
• Tellus Power builds the chargers in the US without large on-site transformers
• Next target is electric garbage trucks with similar duty cycles
