Plug, Store, Profit – Economic Potential of Bidirectional Fleets

The study evaluates the economic impact of bidirectional charging for electric vehicle fleets, providing fleet operators with a decision-making basis for transitioning to vehicle-to-grid (V2X) capable vehicles.

Key insights include:

  • TCO Dominance & Cost Savings: The Total Cost of Ownership (TCO) for EVs above the small car segment beats traditional combustion engines. Higher initial purchase and infrastructure costs are fully offset by lower energy and maintenance costs, THG quota revenues, and massive tax privileges.
  • Leasing, Insurance & Warranties: Monthly leasing rates for bidirectional EVs average 28% higher than fossil-fueled counterparts, while insurance costs match standard unidirectional EVs. Financial risks remain minimal as manufacturers offer extensive 8-year battery warranties backed by anti-aging protection.
  • Privileges & Revenue Streams: Fleet electrification unlocks substantial operational savings through smart PV self-consumption, peak shaving, and dedicated vehicle-to-grid charging tariffs. Operators additionally benefit from full vehicle tax exemptions until 2035 and sharply reduced company car taxation.
