Press release

Stockholm, Sweden, 15 April 2026

After proving Vehicle to Everything with private households and demonstrating full grid integration at the Stenberg Housing Association, Energy Bank is now installing 200 bidirectional chargers in SE3 and SE4, connecting multiple grid operators through a single energy partner.

Bidirectional charging works. It works as Vehicle to Home (V2H) with private customers who already use their EVs to optimize energy consumption behind the meter. At the Stenberg Housing Association in Hudiksvall, Energy Bank has also shown that it works as Vehicle to Grid (V2G) with measurable grid services, including frequency stabilization.

Now it is time to scale. Energy Bank is installing 200 bidirectional chargers in the SE3 and SE4 electricity price areas. The pilot is expected to become the world’s first and largest V2X pilot based on DC charging using the CCS standard. In its role as energy partner, Vattenfall ensures that energy from the EV is used in the best possible way across different energy and flexibility markets, independent of grid operator and price area.

The project brings together key players across the mobility and energy value chain: Volkswagen AG, Vattenfall, Energy Bank, and Scania Volkswagen Retailer (SVÅ).

Proven technology, ready to scale

Volkswagen’s MEB and MEB Plus platforms support bidirectional DC charging. With extremely fast response times, the vehicles are well suited for several grid support services, including the FCR market. Energy Bank acts as the technical aggregator, pooling flexibility from all connected vehicles and delivering it via its API integration to Vattenfall.

Energy Bank’s Living Lab Stenberg has confirmed the entire value chain. Vehicle battery, bidirectional DC charger, property and power grid enable real time dispatch of flexibility services. That is why the national rollout is not another technology test. It is the next step toward a commercial offering.

After more than 15 months of continuous operation in the Living Lab, Energy Bank has been able to show that a bidirectional charger generates total revenue in SE2 of around SEK 27,000 per year.

Partner perspectives

Energy Bank

"EVs are often seen only as transport. This project shows they can also become an active and valuable part of the energy system.

Together with Volkswagen and Vattenfall, V2X is now becoming a reality for real users. We are now making the technology available to vehicle owners in Sweden who, together with us, are shaping the path toward commercialization. Pilot participants play an important role in using V2X in everyday life and contribute insights that are crucial for making the technology work at scale.

This is an important step toward a new market where mobility and energy meet, and where the EV owner helps drive the energy transition."

- Klas Boman, Project Owner, Energy Bank

Vattenfall

"The results show that bidirectional charging can play an important role in an energy system with more fossil free electricity. Our collaboration explores how aggregated EV batteries can contribute flexibility and support system balance and stability. If the battery can support the power system and generate revenue, it is a way to improve the economics and value of owning an EV and contribute to further electrification."

- Magnus Berg, Manager Customer Products and Solutions, Vattenfall

Volkswagen AG

"Volkswagen MEB platform vehicles are ready for bidirectional charging today. With fast response times and the ability to deliver multiple grid services, our EVs are not just means of transport. They are mobile energy assets. This project shows what is possible when the right partners collaborate."

- Derek von Rönn, Business Owner, Charging, Volkswagen AG

Pilot participant perspectives

Private households

"What I find most exciting isn’t only what it saves me. It is what it means at scale. If hundreds of thousands of EVs can function as a distributed battery for the power grid, we need to build far less expensive infrastructure. I like that my car contributes to that without me even having to think about it."

- Amer Kadic

"I don’t have solar panels or a stationary battery, just the car and the charger. And still I can contribute to the power grid. That is what surprised me the most. I had never thought my car could be anything more than a vehicle, but now it is part of an energy system. It actually feels pretty cool."

- Mats Häggbring

Tranås Energi

"We have supplied renewable electricity to the people of Tranås for over a hundred years, from hydropower in a mill to a modern energy system. V2G is the next natural step in that journey. With six bidirectional chargers in the pilot, we can now see in concrete terms how EVs can become an active part of the grid, not just a load. As a local energy company, that gives us entirely new tools to balance and strengthen the power grid in a sustainable way."

- Sven Pålsgård, Head of Electricity Network, Tranås Energi

OKQ8

"Bidirectional charging, Vehicle to Grid, is a business opportunity that makes the EV part of the energy system. When an electric vehicle can store and deliver electricity back to the grid, new revenue and value are created. In the pilot, we are testing the technology to learn how it can become part of our future product portfolio and contribute to smarter energy management and faster electrification."

- Daniel Bogdanoski, Product Manager, Energy Solutions, OKQ8

About Energy Bank

Energy Bank develops technology that enables electric vehicles to function as distributed energy resources through bidirectional charging.

Other V2G aggregators package flexibility and decide how it is used. Energy Bank does the opposite. We aggregate capacity from connected EVs and hand control to the grid owner or electricity supplier. The Energy Bank way enables grid owners and electricity suppliers to build tomorrow’s fossil free energy system.
