Plugged In, Powering Up: Sweden Goes V2X

Energy Bank, Volkswagen, and Vattenfall launch Europe's largest CCS-based V2X pilot across Sweden

1 May 2026

A car sitting idle in a car park has always been a depreciating asset. Now, in a housing estate in Hudiksvall, a modest Swedish town, it may also be a revenue stream. That, at least, is the premise behind Europe's largest vehicle-to-everything (V2X) pilot, launched by Energy Bank, Volkswagen and Vattenfall across Sweden.

Fifteen months of prior evidence underpin the commercial logic. At the Stenberg Housing Association in Hudiksvall, a single bidirectional charger running on the CCS standard, the connector found in most European electric vehicles, generated around SEK 27,000 a year in Sweden's energy markets. Modest by the standards of large-scale infrastructure, but real, audited, and enough to make fleet operators pay attention.

Vattenfall acts as a single energy partner, aggregating power returned from connected vehicles and selling it across multiple flexibility markets, irrespective of local grid operators. This removes a headache that has stalled earlier V2X efforts: the fragmented landscape of competing local utilities, each with different requirements and settlement rules. Volkswagen's MEB-platform vehicles, capable of bidirectional DC charging, can respond quickly enough to provide frequency-stabilisation services, among the most financially rewarding products in the Nordic power market.

Running until 2028, the pilot will draw on roughly 200 participants from private households and small businesses. Data generated over that period is expected to inform V2X procurement rules and grid policy across the European Union. Europe's electricity system faces a structural problem: absorbing more wind and solar power demands fast, distributed storage to keep supply and demand in balance. Co-ordinated electric-vehicle batteries are one of the few solutions that can scale quickly enough to be useful.

CCS is the pilot's quiet trump card. Previous V2X deployments relied on the CHAdeMO connector, now largely confined to Japanese vehicles and fading from the European market. By proving the concept on CCS hardware, Energy Bank and its partners are building on infrastructure that fleet operators are already procuring. If the economics hold through 2028, the template may be harder to ignore than it once seemed.
