Historic Test Flight: World's Largest All-Electric Commuter Aircraft Uses Just $5 of Electricity

Executive Key Takeaway

A landmark test flight of a 40-seat electric passenger plane costs less than $5 in electrical energy, demonstrating dramatic cost advantages over jet fuel.

A historic milestone in green aviation was achieved as the world's largest commercial electric aircraft completed a successful 45-minute maiden test flight over central Washington State. Retrofitted with dual megawatt-class electric propulsion motors and liquid-cooled battery stacks, the 40-passenger airliner consumed under 45 kilowatt-hours of grid energy—costing roughly $5.00 at local power rates.
