Pilot overview
One of the world’s largest V2G/V2H pilot projects at time of launch. Key parameters:
| Parameter | Value |
|---|---|
| Partners | Vattenfall, Energy Bank (software), Volkswagen (vehicles), Ambibox (chargers) |
| Chargers | ~200 bidirectional chargers (Ambibox, German supplier) |
| Location | SE3 and SE4 (central and southern Sweden) |
| Installation points | Private households and VW electric car dealerships |
| Participants | ~200 EV owners (households and fleet operators) |
| Duration | 2026–2028 |
| Preceding pilot | 12-month validation at Stenberg housing cooperative, Hudiksvall |
Technical and market structure
- V2G and V2H both in scope — the pilot explicitly covers grid discharge (V2G) and household self-supply (V2H)
- Vehicle eligibility: VW ID. models with 77 kWh or larger batteries — all have supported bidirectional charging for the past two years at time of launch
- Software: Energy Bank’s platform optimises and aggregates EV charging across participants
- Market roles: Vattenfall acts as both BRP and BSP — trading aggregated flexibility into the Balancing Market, Nord Pool, and local flexibility markets. This single-actor BRP+BSP structure is notable given the structural barriers to cross-BRP aggregation in Sweden (see Aggregation › Nordic comparison: Sweden’s cross-BRP problem)
- Participant compensation: EV owners receive compensation linked to flexibility and energy optimisation provided
Strategic intent
Vattenfall explicitly states the objective of launching a commercial V2H/V2G product following the pilot. The pilot generates insight into “how bidirectional charging can be integrated into the electricity system at scale.”
Quote from Magnus Berg, Vattenfall Head of Customer Products & Solutions:
“If the battery can support the grid while also generating revenue, it could improve the economics and value of owning an electric car and contribute to continued electrification.”
International context (from May 2025 article)
- UK: Cornwall Insight data shows V2G could reduce EV driver electricity costs by ~70%; DESNZ-funded V2X Innovation Programme with V2VNY trial
- Australia: ARENA recognises bidirectional charging potential for grid balancing and bill reduction
- US: ChargeScape + Leapoffering VPP participating in California wholesale market
Key claims
- Aggregated EV batteries in SE3/SE4 can participate in multiple markets simultaneously (balancing, day-ahead, local flex)
- Real-world scale testing (not just desk studies) is critical for identifying practical integration challenges
- The combination of V2H (direct consumer benefit) and V2G (grid revenue) is essential for consumer uptake — V2H creates the tangible value that motivates participation
Relevance
This is the most current and largest-scale Swedish V2G deployment as of 2026. The pilot directly tests the market structure hypothesis (Vattenfall as integrated BRP+BSP), the aggregation platform model (Energy Bank), and the revenue-sharing approach for EV owners. Results will be foundational for Swedish V2G commercial rollout post-2028. See Vehicle-to-Grid › Swedish pilots.
